Hedera introduced MirrorNodeAccountBalanceQuery as an SDK-native way to read HBAR balances from the Mirror Node REST API without leaving the SDK query flow. The query is available in JavaScript, Java, and Go, and it supports multiple account ID formats while requiring no HBAR payment.

What this rests on

Claim by claim, with its source
✓
Hedera made MirrorNodeAccountBalanceQuery available in the JavaScript, Java, and Go Hiero SDKs for reading an account’s HBAR balance from the Mirror Node REST API through the SDK query interface.
✓
The new query is presented as the SDK-native replacement for AccountBalanceQuery.

What it means

Who it affects, what changes and what is still unconfirmed

Each sentence links inside to the piece that supports it.

Developers using the JavaScript, Java, and Go SDKs are the group that can notice this first, because the balance lookup now sits inside the SDK query flow instead of requiring a separate REST call path. That changes how HBAR balance reads are handled in day-to-day use of those SDKs.

What changes in practice is the way an account balance is read: the query is described as the SDK-native replacement for AccountBalanceQuery, and it can work with multiple account ID formats without an HBAR payment. What stays the same is that it is still a read of an account’s HBAR balance from the Mirror Node REST API. (per crypto-economy.com)
