Hedera released the MirrorNodeAccountBalanceQuery for its software development kits to streamline HBAR balance lookups. This update shifts balance read traffic from consensus nodes to the Mirror Node infrastructure.
Why it matters
The change improves network efficiency by offloading read traffic, ensuring that consensus nodes remain focused on transaction processing rather than balance queries.
The new method is available in JavaScript, Java, and Go SDKs and supports shard.realm.num, EVM addresses, public-key aliases, and contract IDs. Release v0.77 initiates the zero-throttling of the legacy consensus-node endpoint.
The players
Hedera
Hedera is a decentralized public network that provides infrastructure for developers to build applications using distributed ledger technology.
The details
Developers can implement the new tool by replacing the old import while keeping their existing setAccountId and execute pattern. The new query method requires no HBAR payment and features built-in automatic retries to handle transient errors.
Timeline

The Tech Race
This move reflects the ongoing evolution of distributed ledger architectures as they attempt to optimize for scalability by separating read-heavy operations from transaction-critical consensus processes. It marks a transition away from monolithic node requests toward specialized, load-balanced infrastructure tiers.
Developers must update their software imports to ensure continued functionality for balance checks as legacy consensus-node endpoints are throttled to zero. These changes reduce costs for users by removing the HBAR payment requirement for standard balance lookups.
The takeaway
Developers should migrate to the MirrorNodeAccountBalanceQuery to take advantage of the free, automated, and more robust balance lookup system. This migration ensures long-term compatibility as Hedera deprecates older consensus-based query patterns.
