Flow Account API

This API is an intermediary for non-custodial Flow wallets. It has two responsibilities:

• Creating a new account on the behalf of a just-initialized wallet.
• Maintaining a registry of publicKey -> accountAddress.

Running locally

This project uses Docker Compose and the Flow Emulator to simulate a blockchain environment on a local machine.

Run this command to start the Docker Compose network:

make run

Run with emulator outside of Docker

Start the emulator using the flow.json file in this directory:

flow emulator start

In a separate process, launch the API:

make run-with-local-emulator
