• #5179 60951cb0166d8f55615294b2b71de4c3526128e9 Thanks @jxom! - Fixed waitForTransactionReceipt treating the awaited transaction as its own replacement when its receipt was unavailable.

• #5142 e65f6640031af871622a4929d58a1593695c488c Thanks @rubenmarcus! - Fixed waitForTransactionReceipt so concurrent calls for the same hash on one client each honor their own timeout, confirmations, pollingInterval, retryCount and checkReplacement instead of inheriting the first call's options.

viem@2.56.9

Patch Changes

• #5123 2068265d2fefb41da2ca672f7b8ef0d221efdbde Thanks @rabbitmainnet! - Added Rabbit Chain Testnet (chain ID 9280) to viem/chains.

  +]

• #5112 c704647d93ed5eaabe3ca9e22fdd4f7e9132b641 Thanks @spalladino! - Added optional maxUsedGas to simulateBlocks call results, preserving the per-call maxUsedGas reported by eth_simulateV1.

  maxUsedGas is the node's measurement of the gas used by a call before gas refunds are applied – it is not a guaranteed minimum sufficient gas limit for the call. It is undefined against nodes that do not report it, and is available on both successful and failed call results.

• #5126 6feacb3a9066b47d3f083a0da0da2d8172577870 Thanks @jxom! - viem/tempo: Added PropAMM actions.

• #5077 b8c79781ecc7bb3c99e14a0e2164ea6245a00a30 Thanks @dmytrozahumennov-wb! - Added whitechainSepolia to viem/op-stack chain exports.

viem@2.56.5

Patch Changes

• #5069 86adf420cfb20721ff99aa5bf6e6c1017588d473 Thanks @moyanghe-uniswap! - Fixed stateOverride being silently dropped by estimateGas in viem/linea — it was destructured into an unused rest object and never serialized onto the linea_estimateGas request, so overrides never reached the node.
