📝 WalkthroughWalkthroughThe Solana SDK now supports environment-specific settlement seeds, program IDs, state PDAs, and delegate authorities. Order PDA and quote derivation pass the environment explicitly. New helpers are exported from the SDK. ChangesSolana settlement PDA support
Estimated code review effort: 3 (Moderate) | ~20 minutes Merge Risk: 🟡 Moderate · up to The SDK now derives settlement addresses by environment, but callers can corrupt cached seed data and existing consumers importing SETTLEMENT_SEED from the package root may no longer compile. Resolve the seed mutability and preserve compatibility or release this as an explicit breaking change before merge. Sequence Diagram(s)sequenceDiagram

In `@packages/sdk-trading-solana/src/index.ts`:
- Line 4: Update the package root exports in the index entry point to preserve
the existing SETTLEMENT_SEED export from orderPda, preferably as a deprecated
compatibility alias, while retaining the current findOrderPda and ORDER_SEED
exports. Do not remove the root import contract unless the package is explicitly
versioned as a breaking release.
In `@packages/sdk-trading-solana/src/orderPda.ts`:
- Around line 3-4: Restore the public SETTLEMENT_SEED export from the package
root for production compatibility, marking it deprecated if appropriate. Reuse
the existing settlement-seed definition behind getSettlementSeed rather than
introducing a duplicate value, and preserve current imports and behavior for
other exports.
In `@packages/sdk-trading-solana/src/settlementSeed.ts`:
- Line 35: Update getSettlementSeed to return a copy of the environment seed
rather than the mutable Uint8Array stored in SETTLEMENT_SEEDS, while preserving
the existing environment lookup behavior.
