Release notes
In this release, we:
onBeforeAssembleTxhook to wallet connectors for quicker estimationSummary
This PR introduces two approaches to enable more optimal transaction speeds from estimation to summary generation:
Connector Aware Estimation
Adds the
onBeforeAssembleTxfunction to the connector interface. This allows for connector specific modifications to a transaction request to be added before the SDK assembles the transaction. A specific use case for this is the SVM/EVM connectors that fund a transaction using an associated predicate account.Inverted Submission Flow
Utilises the change made to the
connector.sendTransaction()signature in #3669 whereby we can now return astring | TransactionResponse.fuels-ts/packages/account/src/connectors/fuel-connector.ts
Lines 47 to 51 in e8494fa
This approach enables #3665 to allow connector transactions to submit and generate a transaction summary in apps in a single request.
Proof Of Concept
A demo using the above approaches can be seen in the connectors repo here. The result of which can be seen here:
