Tx Submit API

Submit signed transactions over HTTP

Accept signed Cardano transactions over HTTP and submit them to a node through its local transaction submission protocol.

How it works

An HTTP boundary for local transaction submission

Tx Submit API accepts a CBOR-encoded signed transaction over HTTP and forwards it to a connected Cardano node using Ouroboros LocalTxSubmission. Its API follows the cardano-submit-api specification, so existing clients can use the same submission contract.
