tBTC, the leading decentralized, trust-minimized Bitcoin bridge, is now live with direct native minting on Starknet — one of the most advanced Ethereum Layer 2 networks powered by ZK-rollup technology.

With this launch, Bitcoin holders can now seamlessly mint tBTC directly on Starknet, eliminating the need to bridge via Ethereum first. This brings the full security, transparency, and 1:1 BTC peg of tBTC natively to the Starknet ecosystem.

This is a significant milestone as it::

Enables Bitcoin to flow into Starknet’s DeFi protocols (DEXs, lending, stablecoins)
Reduces fees and friction for BTC onboarding
Maintains tBTC’s unmatched decentralization and non-custodial architecture

The launch also opens the door to future incentive programs designed to bootstrap BTC liquidity and drive adoption of Bitcoin-backed DeFi use cases on Starknet.

Why it matters: Starknet is emerging as one of the most scalable, developer-friendly ZK-rollups, and native BTC liquidity will unlock new opportunities for the Starknet DeFi ecosystem. This is part of tBTC’s broader vision to make Bitcoin universally accessible across major chains, with no compromises on decentralization or security.
