Crypto: Fireblocks To Integrate Stacks For Institutional-grade Bitcoin Defi

The Bitcoin network has an average block time of about 10 minutes, which creates a challenge for decentralized finance applications.

Update (2-4-26 at 6:49 UTC): This article has been updated to show the correct Stacks block time as 5 seconds

Fireblocks, an institutional-grade crypto infrastructure company, announced on Wednesday that it will integrate Stacks, a decentralized finance (DeFi) layer for the Bitcoin protocol, to give institutional clients access to lending and yield-bearing opportunities.

The integration bypasses the 10-minute Bitcoin block time by leveraging the Stacks blockchain, which has an average block time of about 5 seconds, a Stacks spokesperson told Cointelegraph.

All Stacks transactions settle to the Bitcoin ledger for finality. Removing the 10-minute BTC block time barrier resolves one of the most common objections for financial institutions looking to use BTC-based DeFi applications, the Stacks spokesperson said.

The integration will go live in “early” 2026, according to Fireblocks, but no exact timeline for the rollout was announced.

The Fireblocks and Stacks integration reflects continued institutional interest in Bitcoin DeFi even amid a market downturn that has caused the price of Bitcoin (BTC) to drop by about 40% from its all-time high above $125,000 reached in October 2025.

There was about $5.5 billion in total value locked (TVL) in Bitcoin-based DeFi applications at time of writing, according to DeFiLlama.

The TVL in Bitcoin DeFi applications began rising in October 2024, surging from about $704 million to over $9 billion by October 2025, before dropping back to current levels, according to DeFiLlama.
