Account Management

How to manage accounts addresses

Flow accounts are not derived from a private key. This creates an issues for testing, since you need to create actors in a specific order to use their addresses properly. In order to reduce this friction we made a handy method getAccountAddress, which allows you to access specific address using an alias. This way you can think about actual actors - for example Alice and Bob - without needing to know their Flow addresses. It also helps you to write tests in a sequential or non-sequential way. Calling this method for the first time will create a new account and return the address. Calling it a second time with the same alias again will return the Flow address for that account, without creating new account.


Resolves name alias to a Flow address (0x prefixed) under the following conditions:

  • If an account with a specific name has not been previously accessed, the framework will create a new one and then store it under the provided alias.
  • Next time when you call this method, it will grab exactly the same account. This allows you to create several accounts up-front and then use them throughout your code, without worrying that accounts match or trying to store and manage specific addresses.

const main = async () => {
  const Alice = await getAccountAddress("Alice");
  console.log({ Alice });
