Bitlayer Launches BitVM Bridge Mainnet: Bringing Bitcoin to the DeFi World Safely and Cost-Effectively

Jakarta, August 2025 — Bitlayer, an innovative Layer-2 platform based on BitVM technology, officially announces the launch of the BitVM Bridge Mainnet. This innovation serves as a trust-minimized solution that allows Bitcoin liquidity to flow into the DeFi ecosystem without relying on centralized custodians.

With the BitVM Bridge, users can lock their BTC in the BitVM smart contract and receive YBTC, a token pegged 1:1 with BTC. YBTC can then be utilized for various DeFi activities such as staking, lending, trading, and liquidity provision—similar to the concept of wrapped BTC, but without the risks of a third party controlling the assets.

Advantages of the BitVM Bridge:

BTC is secured directly through the smart contract, with a mechanism that allows participants to detect and prevent fraudulent attempts.

Access to various DeFi opportunities without dependence on centralized entities, while maintaining value equivalent to BTC.

Roadmap and Architecture

Bitlayer is developing in three phases:

1. Phase 1 (Proof-of-Stake) — launched April 2024.

2. Phase 2 (BitVM-based Rollup) — starting 2025, providing full support for EVM-based smart contracts.

3. Phase 3 (High Scalability) — targeted for late 2025, capable of handling up to 20,000 transactions per second with a confirmation time of only 3 seconds.

Technically, Bitlayer combines Proof-of-Stake consensus for high performance with rollups that rely on the security of the Bitcoin network. As a result, transaction finality on Layer-2 can be achieved in seconds, while absolute finality on Layer-1 is achieved within a few days.
