erc4337Fetcher()

erc4337Fetcher<T>(params): Promise<void>

Defined in: trackers/erc4337Tracker.ts:69

A fetcher for initializePollingTracker from @tuwaio/pulsar-core that checks a UserOperation once through eth_getUserOperationReceipt.

The bundler client comes from createBundlerRpcClient of @tuwaio/orbit-evm, which caches it in memory and contacts tx.bundlerUrl, else api.pimlico.io with tx.pimlicoApiKey, else the rate-limited public.pimlico.io.

Invalid chainId: stops polling (keeping the transaction) and calls onFailure with a reason.
Receipt not available yet: calls onIntervalTick with status: 'pending'.
Receipt with success: true: stops polling (keeping the transaction) and calls onSuccess with the bundle hash.
Receipt with success: false: stops polling (keeping the transaction) and calls onFailure with the revert reason.
Any other error is rethrown, so the polling tracker counts it as a failed attempt.

Parameters
