How to configure signing accounts

By default, Orchestrate (tx-signer worker) signs transactions using in-memory private keys which are identical to those pre-funded in Geth, see .env.

If you want to use another private key to sign transactions, please fill the SECRET_PKEY variable in the .env file. We can list several private keys separating them by a whitespace.
