The Transaction Builder endpoints let you construct unsigned Cardano transactions server-side. Each endpoint returns a CBOR-encoded transaction body that you sign locally with your keys and submit via the transaction submission endpoint. This separation keeps signing keys on the client while offloading UTXO selection, fee calculation, and protocol-parameter handling to Nexus.

Available endpoints

Stake delegation

Stake registration

DRep registration

Typical flow

  1. Call the relevant builder endpoint with the required inputs.
  2. Receive the unsigned transaction body (CBOR hex).
  3. Sign locally with your wallet keys.
  4. Submit the signed transaction via POST /v1/transactions/submit.
