On February 4, 2026, Stacks announced an integration with Fireblocks that will let the platform's 2,400+ institutional clients deploy BTC into Bitcoin-native DeFi on Stacks. According to the announcement, Fireblocks secures more than $5 trillion in annual digital asset transfers, and the integration will use enterprise-grade infrastructure for custody, settlement, trading, and payments.

Fireblocks said Wednesday it will integrate Stacks, a Bitcoin-aligned DeFi layer, to offer institutional lending and yield opportunities.

Fireblocks expects the rollout in early 2026, without a specific launch date.
