Fireblocks, a digital asset infrastructure firm securing trillions in annual transactions, has launched Wallet Pools, a feature that groups multiple vaults into a single transaction source. The system uses a health-tiered round-robin algorithm to automatically route transactions to operational vaults, avoiding bottlenecks caused by the nonce mechanism on Ethereum. Two companion features were introduced simultaneously: Transaction Timeout, which marks never-confirming transactions as failed before they hit the blockchain, and Account Traffic Control, a real-time monitoring layer alerting operations teams when vault health deteriorates. Fireblocks serves thousands of organizations, including BNY Mellon and Revolut, across more than 150 blockchain networks.
