INDEXER_EVENT_DECODE_FAILED

Log topic doesn't match any ABI event

What happened

A log was fetched with a topic0 that isn't in the contract's ABI — typically a stale ABI after a contract upgrade, or wrong contract address.

How to fix

Refresh the ABI for the contract address (via cast interface or a redeployed artifact) and restart the indexer.

Example

// Refresh the typed contract after upgrade
const typed = createTypedContract({ abi: freshAbi, address, client });
