…into bump-viem-2.37.7
Picks up the HyperEVM chain definition (id=999) added in viem 2.42.0, which is required to avoid the chain-lookup collision with wanchainTestnet (also id=999). Before this bump, getViemChain in src/cli/handler.ts was returning Wanchain Testnet for chain id 999 because viem 2.37.x has no hyperEvm export, breaking bundle tx submission on HyperEVM (Wanchain serialization rejected by HyperEVM RPC). Also benefits from: - 2.43.4: fixed getUserOperationHash for EIP-7702 UserOperations - 2.43.6: fixed paymasterSignature encoding in toPackedUserOperation - 2.44.4: optional assertChainId on sendTransaction No breaking changes outside the viem/tempo subpackage, which alto does not import. Strict tsc passes; ox's TypeScript >= 5.4 peer requirement surfaces a warning but is informational only (build compiles cleanly against TS 5.3.3).
