txReceipts

txReceipts is a stream of all transaction receipts in each newly mined block.

Service available via Gateway only.

Note: Gateway must have a node connection to both Consensus Layer and Execution Layer as well as be using the eth-ws-uristartup argument (see How to connect Go-Gateway to consensus layer).
