BitcoinOS (BOS), the good contract working system designed for Bitcoin, introduced on Monday, February 17, 2025, the launch of the BitcoinOS Grail Bridge testnet app.
It's right here, BOSes!
BitcoinOS Grail testnet bridge is now LIVE!
For the primary time, you may trustlessly bridge BTC between Bitcoin testnet and a number of EVM chains utilizing our groundbreaking ZK know-how.

In a press launch shared with Cryptonews, the agency said that the app will allow safe, trustless BTC transfers throughout a number of blockchain networks, representing a notable development in cross-chain Bitcoin interactions.
Introducing the Grail Bridge Testnet
The primary-stage testnet launch of the Grail app will supply a sensible instrument for each customers and builders. It introduces one-way bridging from Bitcoin testnet to Ethereum Digital Machine (EVM)-compatible chains.
This transfer is meant to maximise person engagement and ecosystem participation. Preliminary integrations have been accomplished with Ethereum Holešky, Base Sepolia, Mode Sepolia, and Merlin Chain Testnet, stated the agency.
Notably, the event journey included the primary Bitcoin Zero-Information (ZK) bridge transaction on Merlin Chain again in November 2024. This was a serious milestone exhibiting the platform’s technical means.
Customers can entry the Grail app by a number of wallets, together with OKX, Xverse, UniSat, Bitget, and different Pockets Join-supported wallets.
“With deployment already secured with key tasks throughout crypto and web3 ecosystems as companions, this milestone marks a major step in the direction of BOS’s mission to unlock Bitcoin’s ‘holy grail’ answer for trustless scaling, whereas preserving the soundness and integrity of Bitcoin’s core protocol,” stated Edan Yago, a core contributor to BOS.
By initiating the launch with EVM chains, BOS seeks to interact the biggest attainable person base.
Roughly 90% of DeFi exercise happens on EVM-compatible chains, the place most wrapped Bitcoin additionally resides.
The transfer capitalizes on the confirmed observe document of EVM chains in Zero-Information Proof (ZKP) functions and their dominance within the DeFi house.
Technological Breakthrough with BitSNARK
Grail is the primary utility constructed on BitSNARK, BOS’s zero-knowledge proof verification system.
In contrast to conventional bridges counting on custodians or multi-signature schemes, Grail makes use of ZKP know-how.
BitcoinOS plans to permit two-way bridging by the tip of Q1 2025, with a small-scale transaction from Ethereum to Bitcoin on the mainnet.
The complete mainnet launch is predicted in Q2 2025, following safety audits and deliberate integration with non-EVM ecosystems like Cardano and Solana.
Cross-chain interactions have lengthy been some extent of friction for Bitcoin, with centralized custodians and wrapped belongings standing as obligatory however imperfect options.
Grail’s integration of zero-knowledge proofs introduces a brand new paradigm—one the place Bitcoin can transfer past these trade-offs with out compromising its foundational rules.
If BOS succeeds in scaling this method, it may shift how builders and establishments take into consideration Bitcoin’s position in multi-chain ecosystems, not as a static asset however as an energetic participant in decentralized finance.
