+## Multi-Asset Settlement (#417)
+
+Adds per-token developer balances and asset parameter on `receive_payment`.
+
+### New Storage Keys
+
+- `DeveloperBalanceByAsset(Address, Address)` — developer → asset → balance
+- `GlobalPoolByAsset(Address)` — asset → global pool
+- `SupportedAssets` — registered asset whitelist
+
+### New Error Variants
+
+- `AssetNotConfigured = 13` — unregistered asset rejected
+- `GasExhaustionRisk = 14` — added (already referenced by existing tests)
+
+### New Functions
+
+- `add_asset(admin, asset)` — admin-only asset registration (prevents unregistered token dust)
+- `get_assets(admin)` — list supported assets
+- `receive_payment_asset(caller, amount, to_pool, developer, asset)` — asset-aware payment
+- `withdraw_developer_balance_asset(developer, amount, asset)` — per-asset withdrawal
+- `get_developer_balance_asset(developer, asset)` — per-asset view
+- `get_global_pool_asset(asset)` — per-asset pool view
+- `get_all_developer_balances_asset(admin, asset)` — per-asset admin view
+
+### Backwards Compatibility
+
+`receive_payment` (4-param, old signature) kept as shim calling `receive_payment_asset` with the native asset. Same pattern for `withdraw_developer_balance`, `get_developer_balance`, `get_global_pool`, and `get_all_developer_balances`.
+
+### SDK 22 Test Fixes
+
+Fixes 41+ pre-existing compilation errors and 20 runtime failures in `settlement/src/test.rs` and `test_views.rs` caused by Soroban SDK 22 changes to `try_` client method signatures:
+
+- `panic_message`: `downcast_ref<&str>` → `downcast_ref<String>` (no_std compat)
+- `is_error`: matches both `Err(Ok(Error))` (non-Result fn panics in SDK 22) and `Err(Err(InvokeError::Contract(code)))`
+- `is_error_vec` / `is_error_result` / `is_not_initialized_result`: handle `Result<SettlementError, InvokeError>` error slot
+- All `try_get_all_developer_balances` / `try_get_developer_balances_page`: double `.unwrap().unwrap()`
+- `GasExhaustionRisk` assertion: wrapped in `Err(Ok(...))`
+- `is_not_initialized`: uses `is_type(ScErrorType::Contract) + get_code()` for SDK 22 `Error` type
+- Pre-existing page size cap test: 51 not 50 (matches `MAX_DEVELOPER_BALANCES_PAGE_SIZE = 100`)

+## Gas Profiling Harness
+
+Adds a reproducible gas-profiling harness for vault, settlement, and revenue_pool contract entrypoints:
+
+- **Vault** (9 benchmarks): `init`, `deposit`, `deduct`, `batch_deduct[k=1,10,50]`, `withdraw`, `withdraw_to`, `distribute`
+- **Settlement** (6 benchmarks): `init`, `receive_payment`, `withdraw_developer_balance`, `batch_receive_payment[k=1,10,50]`
+- **Revenue Pool** (6 benchmarks): `init`, `deposit`, `distribute`, `distribute_full`, `withdraw`, `batch_receive_notification[k=50]`
+
+Batch sizes test k=1, k=10, `MAX_BATCH_SIZE` (50). Uses real Soroban SDK 22 `cost_estimate().budget()` API with `/saturating_sub` diff. Output format `GAS| <label> | <cpu> | <mem> | <description>` parsed by `scripts/gas_profile.sh` into deterministic `BENCHMARKS.md`.
