Fireblocks Rolls Out Wallet Pools to Streamline Crypto Vault Management

Fireblocks has launched Wallet Pools, a feature that consolidates multiple vaults into unified pools to eliminate stuck transactions in vault management. This system uses a health-tiered round-robin algorithm to route transactions, automatically avoiding stuck lanes and sending traffic through ones that are working.

The new feature tackles the problem of stuck transactions by grouping multiple vaults into a single transaction source, distributing transactions across the pool. When one vault encounters a stuck transaction, the algorithm routes new transactions to healthy vaults in the pool.

Wallet Pools didn't arrive alone; Fireblocks simultaneously introduced Transaction Timeout and Account Traffic Control, two features that address different parts of the same reliability problem. Transaction Timeout handles delayed transactions that never confirm but also never officially fail, while Account Traffic Control functions as a real-time monitoring layer that sends alerts when vault health deteriorates.

Fireblocks serves thousands of organizations, including names like BNY Mellon and Revolut, which process enormous transaction volumes across more than 150 blockchain networks. The dependency on single vaults has been a persistent vulnerability in institutional crypto operations, but Wallet Pools directly reduces that single-point-of-failure risk by distributing the operational load.
