Hedera Introduces MirrorNodeAccountBalanceQuery for HBAR Balance Reads
Hedera (HBAR)

crypto-economy.com reports that Hedera has launched MirrorNodeAccountBalanceQuery, an SDK-native tool replacing the legacy AccountBalanceQuery. This new method allows developers to read HBAR balances directly from Mirror Node infrastructure without leaving the standard query interface. It is now available in JavaScript, Java, and Go Hiero SDKs and requires no additional dependencies or client configuration.
The migration shifts balance reads away from consensus nodes, turning a REST-based data path into a first-class SDK workflow. MirrorNodeAccountBalanceQuery retrieves data from the GET /api/v1/balances endpoint and is free to execute with no query payment required. It automatically retries transient 5xx responses or network failures using exponential backoff and accepts various account identifiers including shard.realm.num and EVM addresses.
The update is mandatory for applications using AccountBalanceQuery because the consensus-node endpoint is throttled to zero on testnet and mainnet as of Consensus Node software v0.77. Developers must update their SDKs to replace the deprecated query to avoid operational issues. Rust, Swift, and C++ applications can still access balance data directly through the Mirror Node REST endpoint. Hedera recommends adding a short retry or polling step when reading balances immediately after submitting a transaction due to propagation delays.

HBAR is trading at $0.1040 with a 1-hour buy ratio of 59.5%, indicating strong immediate buying pressure. This 1-hour ratio is higher than the 4-hour ratio of 53.3% and the 24-hour ratio of 50.8%, suggesting that buying intensity is building in the short term. The Volume Delta for the last hour is +$134,179, showing net inflows that exceed the 4-hour delta of +$217,601 and the 24-hour delta of +$141,725. The Cumulative Volume Delta (CVD) for the 24-hour period closed at +$408,210, confirming net positive flow over the day. Net buying occurred for 18 of the last 24 hours, with a total spot volume of $8,247,356 and 55,437 trades recorded. This flow indicates active accumulation rather than distribution during the reporting period.
The latest daily buy ratio of 49.3% sits at the 50th percentile of the last 322 days, against a median of 49.2% - ordinary for this coin.
Was that an ordinary day?
The same Binance spot measurements for HBAR, averaged over the days leading up to the story.
Over the preceding week, the 7-day average buy ratio was 49.9%, making today's 24-hour ratio of 50.8% slightly above average by 0.9 points. Volume activity was subdued, with current volume at 0.14x the weekly average, indicating lower participation than usual. Net buying days were limited to 3 out of the last 7 days, contrasting with the 18 days of net buying in the last 24 hours. The price increased by 8.5% over the 8-day period, while the total Volume Delta for that week was -$6,431,003. This suggests that while the price has risen, the underlying volume flow has been net negative over the longer timeframe, making today's positive flow unusual compared to the weekly trend.
