createSafeFetcher()

createSafeFetcher(options?): (__namedParameters) => Promise<void>

Creates a fetcher for initializePollingTracker from @tuwaio/pulsar-core that checks a Safe multisig transaction once through the Safe Transaction Service API of tx.chainId (SafeTransactionServiceUrls). tx.txKey is the safeTxHash and tx.from the Safe address.

Requests: GET <service>/multisig-transactions/<safeTxHash>/, and while it is not executed, GET <service>/safes/<from>/multisig-transactions/?nonce=<nonce>.

Executed: calls onSuccess or onFailure (by isSuccessful) and stops polling, keeping the transaction.
Another transaction with the same nonce was executed: calls onReplaced with it and stops polling, keeping the transaction.
Still pending pendingTimeoutMs after submissionDate (one day by default): calls onFailure with the status and stops polling, keeping the transaction. Without a timeout (null) it keeps waiting.
The service returns 404: calls onFailure() without a response and stops polling, keeping the transaction.
An unsupported chain or another failed request throws, so the polling tracker counts it as a failed attempt.

Parameters

options?

SafeTrackerOptions = {}

The tracker options.

Returns

The fetcher. Its promise resolves when the check is done.
