Hedera Launches MirrorNodeAccountBalanceQuery for SDK-Native HBAR Balance Reads
- —Available in JavaScript, Java and Go SDKs with no new dependencies
- —Free to execute, no query payment, with automatic retries on 5xx errors
- —Accepts shard.realm.num, EVM addresses, public-key aliases and contract IDs
- —AccountBalanceQuery consensus-node endpoint throttled to zero from v0.77
Why it matters: Hedera developers must update their SDKs, as the legacy balance-read endpoint stops working on testnet and mainnet.
