cardano-tx-submit-api

The cardano-submit-api is a program that provides a web API allowing transactions (generated by external wallet or SDK ) to be posted to the Cardano blockchain. It is designed for exchanges and wallets who manage their own UTXO distribution with full control of transaction generation and signing. To submit a transaction to the network (mainnet, staging, or any of the testnets), cardano-node must be running and have access to the genesis file and genesis hash value for the network.

To build and run the cardano-submit-api see the documentation

After setting up a locally running cardano-node, follow these instructions to build and run the web API using Nix.

In a new terminal or emulator, change to the Cardano explorer root directory:

Build submit api where <network> can be staging | testnet | mainnet :

nix-build -A scripts.<network>.submit-api -o submit-api-tx

Export path:

export PATH="${HOME}/cardano-node/state-node-mainnet/node.socket:${PATH}"

Run the submit-api

./submit-api-tx \
 --config /submit-api/config/ \
 --genesis-file ../cardano-node/configuration/mainnet-genesis.json /
 --port 8101/
