CONTRACTS_ABI_MISMATCH

ABI doesn't match deployed contract

What happened

The ABI passed to createTypedContract({ abi, address }) doesn't match the deployed bytecode — typically a stale codegen output after the contract was redeployed.

How to fix

Re-run 0g contracts generate --abi <fresh-forge-artifact>.json --out <dir> to refresh the typed client.

Example

0g contracts generate --abi ./out/MyContract.sol/MyContract.json --out ./src/typed
