Account management


Let's review some code examples on how to manage Accounts:

Creating a custom account system

In the following code snippet we create a custom Account system, that enables us to process Atoms in any way we might see fit.

import { RadixAccountSystem, RadixAtomUpdate, RadixAtom } from 'radixdlt'
export default class CustomAccountSystem implements RadixAccountSystem {
public name: 'CUSTOM'
public async processAtomUpdate(atomUpdate: RadixAtomUpdate) {
const atom: RadixAtom = atomUpdate.atom
// This is either 'STORE' or 'DELETE'
const action = atomUpdate.action
// Do whatever you want with your atom here
if (action === 'STORE') {
// Add atom contents to state
} else {
// Remove atom contents from state

Note: the atomUpdate has an action field, which can be STORE or DELETE.

A DELETE can occur when an Atom fails to validate or is rejected by the consensus. It's crucial to handle it correctly in the particular context of the application.

Once you have your custom account system, you can simply add it to the account using the addAccountSystem() method:

const account = RadixAccount.fromAddress('JEaSfBftmFdseSRKfTm6hJNhQi3FAEqmVzAPTxsf55wPqXvBxRB')
const myAccountSystem = new CustomAccountSystem()
