Hedera Ships MirrorNodeAccountBalanceQuery as SDK-Native Replacement for AccountBalanceQuery
- —Available now in the JavaScript, Java and Go Hiero SDKs
- —Free to run: no query payment and no HBAR required
- —Accepts shard.realm.num, EVM address, public key alias and contract ID
- —AccountBalanceQuery consensus endpoint throttled to zero in v0.77
Why it matters: Hedera developers must migrate, as the old balance query no longer works on testnet or mainnet.
