Fireblocks integrates Stacks for Bitcoin DeFi

Fireblocks said it will integrate Stacks to give institutional clients access to Bitcoin-based lending and yield products.

The integration allows decentralised finance applications to bypass Bitcoin’s 10-minute block time by using Stacks’ roughly five-second blocks, with transactions settling back 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,”

A Stacks spokesperson said.

Fireblocks said the integration is expected to go live in early 2026, though the company did not provide a precise rollout date.

The move comes as institutional interest in Bitcoin DeFi persists despite bitcoin trading about 40% below its October 2025 all-time high above $125,000.

Bitcoin-based DeFi applications currently hold about $5.5 billion in total value locked, down from a peak above $9 billion in October 2025, according to DeFiLlama data.

Supporters argue Bitcoin DeFi could eventually rival traditional finance, though critics warn that growing reliance on second-layer networks could threaten Bitcoin’s base-layer decentralisation.

At the time of reporting, Bitcoin price was $72,936.06.
