# Submit External Transaction

**POST /proxy/transactions**

<p align="right">status: <strong>stable</strong></p>

Submits a transaction that was created and signed outside of cardano-wallet.

NOTE: Unlike the `submitTransaction` endpoint, there are no
guarantees that a transaction accepted by this endpoint will
actually be included in the chain. It's up to the caller to
retry submission until the transaction is confirmed.
