DAPI sends every response uncompressed. rs-dapi's Drive client says compression is "handled by Envoy", but the gateway has no compressor filter, and neither rs-dapi nor rs-dapi-client enables tonic compression. Checked live against mainnet evonodes (DAPI 4.1.x): native gRPC responses carry no grpc-encoding even when the client sends grpc-accept-encoding: gzip, and grpc-web responses carry no Content-Encoding even when the client sends Accept-Encoding: gzip, br.
rs-dapi: Platform and Core responses are gzip-compressed for clients that list gzip in grpc-accept-encoding. Clients that don't list it get uncompressed responses as before. Compressed requests are still not accepted.
rs-dapi-client (native): Platform and Core clients accept gzip responses. This covers rs-sdk, and Swift/Kotlin through rs-sdk-ffi. Nodes that don't compress ignore the header, so new clients work against old nodes. gzip comes from flate2's pure-Rust backend, so iOS and Android builds gain no C dependency.
rs-dapi-client (wasm): unchanged on purpose. Browsers and Node's fetch negotiate HTTP Content-Encoding with the gateway and decompress on their own. Also, grpc-accept-encoding isn't in the gateway's CORS allow-list, so sending it from a browser would fail the preflight.
rs-dapi-client retries: when a gzip response decompresses past the client's max_decoding_message_size, tonic returns ResourceExhausted ("Error decompressing: size limit…") instead of the OutOfRange an uncompressed oversized response gets. ResourceExhausted is retryable and bans the node, so without this fix one oversized response would ban healthy nodes one after another, for a limit that lives in the client. That status is now not retryable, the same as OutOfRange.
Gateway (Envoy): a gzip compressor for grpc-web responses only (application/grpc-web*). It sits above grpc_web, so the trailer frame is compressed too. Native application/grpc responses are never HTTP-compressed; rs-dapi compresses those messages itself. It uses window_bits: 15 (zlib's 32 KiB window) instead of Envoy's 4 KiB default. On the mainnet sample, the default window would cut savings on responses over 64 KiB from 82.6% to 5.5%, and over all messages from 55.2% to 12.3%. The cost is about 144 KiB of zlib state per in-flight compressed response.
dapi-grpc: the native-only transport feature enables tonic/gzip.
The misleading "handled by Envoy" comment and log line in the Drive client are removed, and packages/rs-dapi/doc/DESIGN.md is corrected. The rs-dapi → Drive hop stays uncompressed because it's local.
js-dapi-client in Node (@grpc/grpc-js) already sends grpc-accept-encoding: identity,deflate,gzip, so it gets compressed responses without changes.
Measurements (real responses)
162 read-only responses collected from 3 mainnet evonodes on 2026-10-25 (protocol 13, height 458,086), plus 227 from testnet. Each message was compressed on its own, the way gRPC per-message compression works. Savings are by bytes, gzip level 6, which is what tonic uses.
Testnet (protocol 14): 47.8% overall, 43.1% excluding responses over 64 KB.
The savings come from embedded payloads: contract schemas, documents, epoch and quorum data. Small proofs that are mostly 32-byte Merk hashes don't compress. 37 of the 119 mainnet messages, almost all single-identity proofs of 1–4 KB, come out slightly larger, by at most 23 bytes. I did not add a size threshold. tonic has none built in, and the loss on those messages is tiny next to the gains on the large ones.
zstd-3 saves within 1–4 points of gzip-6 at about 4× less CPU. The cost is a C dependency, so it is left for later. Measured CPU for gzip-6 (single thread, Apple M4 Pro, zlib): median 24 µs to compress a message, 5 µs to decompress, about 117 MB/s compression throughput. That's small next to the cost of producing a proof.
The percentages depend on the query mix, not on production traffic. Mainnet nodes were on 4.1.x, so v5 response shapes may differ somewhat.
How Has This Been Tested?
New rs-dapi test should_gzip_responses_only_for_clients_that_accept_gzip. It serves the Platform service with gzip enabled as in production, over an in-memory connection, and checks three things: a plain tonic client gets no grpc-encoding, a client built with rs_dapi_client::transport::new_platform_client gets grpc-encoding: gzip, and both decode to the same message.
New rs-dapi test should_not_ban_nodes_for_a_gzip_response_over_the_client_limit. A compressible response goes through the real server to a client with a 1 KiB decode limit, and the test asserts the status is not retryable. Without the retry fix it fails with exactly that ResourceExhausted status.
New dashmate unit test that pins the compressor between cors and grpc_web and restricts it to the grpc-web content types.
cargo test -p rs-dapi --lib protobuf_request_errors, cargo test -p rs-dapi --lib server:: and cargo test -p rs-dapi-client --all-features.
cargo check --target wasm32-unknown-unknown for rs-dapi-client and wasm-sdk. flate2 is not in the wasm dependency tree.
packages/dashmate/scripts/validate-envoy-config.js --smoke: all 8 config variants and the rate-limit smoke checks pass on both envoyproxy/envoy:v1.39.0 and the pinned dashpay/envoy:1.39.0-impr.1.
Ran the rendered gateway config in the pinned Envoy image in front of a stub gRPC upstream serving a real 4.3 KB contract proof:
grpc-web + Accept-Encoding: gzip: content-encoding: gzip, 4,396 → 2,083 bytes on the wire, message and trailer frame intact after decompression.
grpc-web without Accept-Encoding: unchanged response.
Native gRPC with message-level gzip: passes through Envoy unchanged (grpc-encoding: gzip, 4,361 → 2,035 bytes, decompresses to the exact payload). Envoy does not HTTP-compress application/grpc.
Breaking Changes
None. Compression only happens when the client asks for it, so old clients see no change, and new clients work against old nodes.

Summary by CodeRabbit
New Features
gRPC clients that advertise gzip can receive compressed responses. Browser clients continue to use browser-managed compression for gRPC-Web responses.
JSON-RPC responses and Drive requests remain uncompressed.
Bug Fixes
Compressed responses that exceed the client’s decompressed-message limit return a non-retryable error.
DAPI sent every response uncompressed: rs-dapi claimed Envoy handled
compression, but the gateway had no compressor filter.
- rs-dapi gzip-compresses Platform and Core responses for clients that
list gzip in grpc-accept-encoding; other clients are unaffected.
- Native rs-dapi-client clients accept gzip responses (pure-Rust flate2,
no new C dependency). The wasm client is unchanged: browsers negotiate
HTTP Content-Encoding with the gateway themselves.
- The gateway gzips grpc-web responses (32 KiB window) for clients that
send Accept-Encoding; native gRPC is never HTTP-compressed.
- A gzip response that decompresses past the client's decode limit is
not retried, like an uncompressed oversized response, so it no longer
bans healthy nodes.
On a mainnet sample, gzip saves 65% of response bytes overall (29%
without responses over 64 KiB); single-identity proofs barely change.

Summary
Client gzip support and retry handling packages/dapi-grpc/Cargo.toml, packages/rs-dapi-client/src/transport.rs, packages/rs-dapi-client/src/transport/tonic_channel.rs, packages/rs-dapi-client/src/transport/wasm_channel.rs, packages/rs-dapi-client/src/transport/grpc.rs
The transport feature enables tonic gzip. Native client constructors accept gzip responses, and pooled client creation uses the new constructors. Wasm constructors are added. Decompression-limit ResourceExhausted statuses are not retried.
DAPI server gzip responses packages/rs-dapi/src/server/grpc.rs, packages/rs-dapi/src/services/platform_service/protobuf_request_errors.rs
Platform and Core gRPC servers enable gzip responses when clients advertise gzip. Tests cover response negotiation, decoding, and decompression-limit errors.
The design document describes compression behavior for Drive requests, native gRPC, gRPC-Web, and JSON-RPC. The Envoy test checks filter order and configured gRPC-Web content types. The Drive client’s disabled-compression comment and startup log are removed.
The change is mergeable with a recommended assertion to ensure grpc-web requests remain uncompressed.

Final validation — Phase 1 + Phase 2
The gzip implementation is correctly scoped across native gRPC, grpc-web, and WASM transports, with no blocking correctness, security, or layering defects found. Three non-blocking test and maintainability improvements remain: Core response compression lacks direct coverage, the retry guard depends on tonic's error wording, and the Envoy test can throw a TypeError instead of reporting an assertion failure. The Rust workspace test failure is unrelated to this PR; one browser test check was still in progress in the supplied CI snapshot.
Triage: normal by gpt-6.1-sol (effort low) — This is a broad cross-cutting change to gRPC transport, server compression, gateway configuration, client retry handling, and protocol error mapping, but it does not alter consensus, funds, cryptography, key handling, or storage.

- [SUGGESTION] packages/rs-dapi/src/server/grpc.rs:55-62: Core response compression lacks direct test coverage
`core_server()` now enables gzip response compression, but the added integration coverage exercises only `platform_server()`. Because `core_server()` is a separate constructor, a future edit could remove or misconfigure its `send_compressed(CompressionEncoding::Gzip)` call without any test detecting the regression. Add a Core-service compression test, or expose the constructor under `cfg(test)` and cover it with a small Core harness.

- [SUGGESTION] packages/rs-dapi-client/src/transport/grpc.rs:133-137: Document the tonic-version dependency of the decompression-limit prefix
`can_retry()` identifies the client-local decompression limit by prefix-matching tonic's English status message. That wording is an implementation detail rather than a stable status discriminator. The existing test will catch a wording change when it runs, but the constant should explicitly identify the tonic decoder source and version so a future tonic upgrade prompts a deliberate review instead of silently changing retry classification if the test is skipped or weakened.
In `packages/dashmate/test/unit/templates/envoyTemplate.spec.js`:
- [NITPICK] packages/dashmate/test/unit/templates/envoyTemplate.spec.js:46-49: Avoid a TypeError when the Envoy compressor block has no content types
If the rendered compressor block contains no matching content-type lines, `match()` returns `null` and the test throws a TypeError before reaching an assertion. This produces a misleading failure and obscures the actual template regression. Normalize the match result to an empty array before mapping it.
Out-of-scope follow-up suggestions (1)
These are valid observations, but they are outside this PR's scope and should be handled in separate issues or author/maintainer-requested PRs rather than blocking this review.
Rust workspace test failure is pre-existing and unrelated — The supplied CI snapshot shows Rust workspace tests / Tests failing in the untouched packages/rs-sdk/src/platform/identities_contract_keys_query.rs because QuerySettings initializers omit verified_protocol_version. The changed files do not include this module, and the failure is unrelated to the gzip transport changes.
Follow-up: Track or fix the rs-sdk QuerySettings initializer issue separately on the appropriate development branch.

Re-review — Final validation — Phase 1 + Phase 2
The PR correctly wires gzip negotiation through the native Platform/Core servers and clients and adds grpc-web compression at the gateway. However, enabling gzip changes tonic's existing 32 MiB response limit to apply after compression, allowing much larger highly compressible responses to be generated and buffered by the public DAPI; this is a blocking unauthenticated DoS risk. CI checks covering the changed code are still in progress.

- [BLOCKING] packages/rs-dapi/src/server/grpc.rs:50-61: Gzip compression bypasses the server's 32 MiB response-size backstop
With tonic 0.14's server encoder, enabling `send_compressed` first serializes the response into an uncompressed buffer, compresses it, and then applies `max_encoding_message_size` to the compressed payload. Before this change, the same 32 MiB limit bounded the raw protobuf response; now a highly compressible response whose uncompressed size exceeds 32 MiB can pass as long as its gzip representation is below 32 MiB. The DAPI must still materialize and compress the larger response before the limit is checked, so an unauthenticated caller can repeatedly consume substantial memory and CPU. The same regression exists in both `platform_server()` and `core_server()`. Preserve a raw/uncompressed response-size bound, or reject responses whose uncompressed encoding exceeds `MAX_ENCODING_BYTES` before compression.

(existing thread: https://github.com/dashpay/platform/pull/5577#discussion_r4369224008)
`core_server()` is a separate production constructor with its own `send_compressed(CompressionEncoding::Gzip)` call, but the added end-to-end test exercises only `platform_server()`. A future Core-only edit could remove or misconfigure gzip while the Platform test continues to pass. A focused Core harness can use an unreachable Core RPC endpoint: `get_blockchain_status` deliberately converts Core RPC failures into absent fields and still returns a successful response, providing a small response whose compression headers can be asserted without a live Core node.

- [SUGGESTION] packages/rs-dapi-client/src/transport/grpc.rs:153-155: Do not trust a remote status message to identify a local decompression limit
After tonic converts a client-side decompression-limit failure into `Status`, `can_retry()` has no provenance indicating that the status was generated locally. A malicious or faulty DAPI node can return `ResourceExhausted` with a message beginning `Error decompressing: size limit`, causing the client to classify the response as non-retryable and skip node failover or banning. This lets the node remain in rotation and repeatedly fail requests. Preserve local decoder-error provenance before converting it to `Status`, or use a transport-level discriminator that a remote peer cannot forge, rather than relying solely on the peer-controlled status message.

With gzip on, tonic checks max_encoding_message_size against the
compressed message, so a highly compressible response larger than
32 MiB raw could be compressed and sent. Cap the Drive client's decode
limit at the same 32 MiB so such a response is refused before DAPI
encodes or compresses it. Also cover core_server's gzip negotiation.

The compression implementation is correctly scoped across native gRPC, WASM, DAPI, and the grpc-web gateway. The raw Drive response bound, Core coverage, Envoy test robustness, and tonic-version documentation address the prior actionable findings; the remaining retry-classification concern does not introduce a material new failure mode because peers already control non-retryable gRPC statuses.

the same way the server does.

Re-review — Final validation — Phase 1 + Phase 2
The gzip negotiation is wired correctly for native gRPC and grpc-web, but enabling tonic response compression changes the existing 32 MiB server limit to apply after compression. Highly compressible raw responses between 32 and 64 MiB can therefore pass the DAPI backstop, while the separately configured Core service still lacks direct compression regression coverage. The Rust workspace test failure is reported as unrelated to the changed DAPI and Envoy paths; several relevant checks remain in progress.

(existing thread: https://github.com/dashpay/platform/pull/5577#discussion_r4369320101)
Both service builders now enable gzip before tonic applies `max_encoding_message_size`. In tonic 0.14.6, the encoder serializes the response, compresses it, and then checks the compressed buffer length, so the configured 32 MiB limit no longer bounds the raw protobuf response. A highly compressible response larger than 32 MiB can pass this check and be sent to a gzip-capable client. The DAPI still materializes the raw response and performs the compression before any limit failure, and the Drive client continues to accept up to 64 MiB, so this is both a weakened response-size invariant and additional per-request memory/CPU exposure. Preserve an explicit raw/uncompressed response bound before compression for both Platform and Core responses; the existing compressed-size limit can remain as an additional bound.

(existing thread: https://github.com/dashpay/platform/pull/5577#discussion_r4369224008)
`CoreServer` has an independent `.send_compressed(CompressionEncoding::Gzip)` configuration, but the current integration tests exercise only the Platform server. The earlier Core harness was removed in commit `3b925224b2`, so deleting or misconfiguring the Core compression line would leave the suite green. Add a small Core-service harness, such as the `getBlockchainStatus` path that succeeds with unreachable upstream services, and verify both plain-client and gzip-capable-client behavior.

DAPI sends every response uncompressed. rs-dapi's Drive client says compression is "handled by Envoy", but the gateway has no compressor filter, and neither rs-dapi nor rs-dapi-client enables tonic compression. Checked live against mainnet evonodes (DAPI 4.1.x): native gRPC responses carry no
grpc-encodingeven when the client sendsgrpc-accept-encoding: gzip, and grpc-web responses carry noContent-Encodingeven when the client sendsAccept-Encoding: gzip, br.Replaces #5576.
What was done?
grpc-accept-encoding. Clients that don't list it get uncompressed responses as before. Compressed requests are still not accepted.Content-Encodingwith the gateway and decompress on their own. Also,grpc-accept-encodingisn't in the gateway's CORS allow-list, so sending it from a browser would fail the preflight.max_decoding_message_size, tonic returnsResourceExhausted("Error decompressing: size limit…") instead of theOutOfRangean uncompressed oversized response gets.ResourceExhaustedis retryable and bans the node, so without this fix one oversized response would ban healthy nodes one after another, for a limit that lives in the client. That status is now not retryable, the same asOutOfRange.application/grpc-web*). It sits abovegrpc_web, so the trailer frame is compressed too. Nativeapplication/grpcresponses are never HTTP-compressed; rs-dapi compresses those messages itself. It useswindow_bits: 15(zlib's 32 KiB window) instead of Envoy's 4 KiB default. On the mainnet sample, the default window would cut savings on responses over 64 KiB from 82.6% to 5.5%, and over all messages from 55.2% to 12.3%. The cost is about 144 KiB of zlib state per in-flight compressed response.transportfeature enablestonic/gzip.packages/rs-dapi/doc/DESIGN.mdis corrected. The rs-dapi → Drive hop stays uncompressed because it's local.js-dapi-client in Node (

162 read-only responses collected from 3 mainnet evonodes on 2026-10-25 (protocol 13, height 458,086), plus 227 from testnet. Each message was compressed on its own, the way gRPC per-message compression works. Savings are by bytes, gzip level 6, which is what tonic uses.
getFinalizedEpochInfosgetCurrentQuorumsInfogetDocuments(DPNS, DashPay)getDataContract/getDataContractsgetEpochsInfoTestnet (protocol 14): 47.8% overall, 43.1% excluding responses over 64 KB.
The savings come from embedded payloads: contract schemas, documents, epoch and quorum data. Small proofs that are mostly 32-byte Merk hashes don't compress. 37 of the 119 mainnet messages, almost all single-identity proofs of 1–4 KB, come out slightly larger, by at most 23 bytes. I did not add a size threshold. tonic has none built in, and the loss on those messages is tiny next to the gains on the large ones.
zstd-3 saves within 1–4 points of gzip-6 at about 4× less CPU. The cost is a C dependency, so it is left for later. Measured CPU for gzip-6 (single thread, Apple M4 Pro, zlib): median 24 µs to compress a message, 5 µs to decompress, about 117 MB/s compression throughput. That's small next to the cost of producing a proof.
The percentages depend on the query mix, not on production traffic. Mainnet nodes were on 4.1.x, so v5 response shapes may differ somewhat.
How Has This Been Tested?
should_gzip_responses_only_for_clients_that_accept_gzip. It serves the Platform service with gzip enabled as in production, over an in-memory connection, and checks three things: a plain tonic client gets nogrpc-encoding, a client built withrs_dapi_client::transport::new_platform_clientgetsgrpc-encoding: gzip, and both decode to the same message.should_not_ban_nodes_for_a_gzip_response_over_the_client_limit. A compressible response goes through the real server to a client with a 1 KiB decode limit, and the test asserts the status is not retryable. Without the retry fix it fails with exactly thatResourceExhaustedstatus.corsandgrpc_weband restricts it to the grpc-web content types.cargo test -p rs-dapi --lib protobuf_request_errors,cargo test -p rs-dapi --lib server::andcargo test -p rs-dapi-client --all-features.cargo clippy -p rs-dapi -p rs-dapi-client -p dapi-grpc --all-features --all-targets --no-deps -- -D warnings.cargo check --target wasm32-unknown-unknownforrs-dapi-clientandwasm-sdk. flate2 is not in the wasm dependency tree.packages/dashmate/scripts/validate-envoy-config.js --smoke: all 8 config variants and the rate-limit smoke checks pass on bothenvoyproxy/envoy:v1.39.0and the pinneddashpay/envoy:1.39.0-impr.1.Accept-Encoding: gzip:content-encoding: gzip, 4,396 → 2,083 bytes on the wire, message and trailer frame intact after decompression.Accept-Encoding: unchanged response.Accept-Encoding: gzip: compressed.grpc-encoding: gzip, 4,361 → 2,035 bytes, decompresses to the exact payload). Envoy does not HTTP-compressapplication/grpc.Breaking Changes
None. Compression only happens when the client asks for it, so old clients see no change, and new clients work against old nodes.
