All notable changes to the TypeScript SDK (propamm) are documented here.

[1.2.2] - 2026-07-01

The swap and swapAndWait functions now attach a hardcoded per-function gas limit and skip node gas estimation, which can under-shoot when execution takes a heavier branch than it simulated. Override the gas limit per call with the new SwapOptions.gasLimit.
PropAmmRouter.gasLimitFor(opts?) returns the gas limit a swap will attach for the given options (the explicit gasLimit, else the per-function default) — for previewing the maximum network fee without sending.

State-override quotes now pin the simulated block.timestamp to the beacon slot's canonical block time (genesis + slot*12) instead of the frame's emit time, falling back to the emit time when no slot is present. Venues validate block.timestamp against the state they pushed, which is keyed to the slot. (#61)

Browser / injected wallet support: ContractClient.fromClients accepts prebuilt viem public and wallet clients (e.g. wagmi's usePublicClient / useWalletClient), so swaps can be signed by a browser wallet instead of a raw private key. (#56)

Breaking: the ContractClient constructor is now private. Build a client from an RPC URL with the new ContractClient.fromRpc static method instead of new ContractClient(...). (#56)

Price levels: subscribe to maker price-level updates and apply them to quotes via PriceLevelsWsSource (WebSocket) or PriceLevelsRpcSource (RPC), plus the PriceLevels container and related utilities. (#51)

Initial release. Core surface for interacting with the PropAMMRouter:
- Router actions: quote, swap, waitForSwap, approve, allowance, and view helpers.
- State overrides: apply fresh pAMM state to quotes via OverridesWsSource (WebSocket) or OverridesRpcSource (RPC), plus utilities.
- Shared helpers and types.
