# accountDelta

> Balance and nonce change events for subscribed addresses.

The server pushes this event when an account's EGLD balance, ESDT token balance, or nonce changes on-chain. It reaches subscribers of `address/{bech32}` (one address) or `accounts` (all addresses network-wide).

## Topic

`address/{bech32}` or `accounts` via [subscribe](/api-reference/ws/subscribe)
