BitcoinOS (BOS) unveiled its highly anticipated Grail testnet bridge app on Monday, which they call the “holy grail” technology that will kickstart a new era of innovation and investment opportunities on Bitcoin.
With the project’s $BOS token presale approaching in February 2025, this milestone has re-established BitcoinOS as a forerunner of the largest blockchain’s tech revolution, and positions $BOS as a staple for gaining exposure to the rebirth of Bitcoin.
As of this week, users can access the Grail bridge testnet to transfer test Bitcoin between Bitcoin Testnet 3 and various EVM-based testnets, including Ethereum Holesky, Merlin, Mode, and Base. While the current implementation focuses on Bitcoin-to-EVM transfers, it showcases the foundational technology that will enable Bitcoin’s first “trustless” bridging experience across the entire crypto ecosystem.
“This testnet brings our technology from concept to reality,” said Edan Yago, core contributor at BitcoinOS. “For the first time, users can experience truly trustless Bitcoin bridging that requires only one honest validator to maintain security.”

What BitcoinOS Is Bringing To Bitcoin
BitcoinOS is promising a fundamental breakthrough in Bitcoin functionality that’s excited investors across the crypto landscape. The project made history in July 2024 by verifying the first zero-knowledge proof on Bitcoin mainnet – a feat that developers had long considered impossible.
This technology enables Bitcoin to achieve unlimited scalability and programmability without compromising its core security or decentralization. The first way BitcoinOS will allow this is by building Grail – Bitcoin’s first trustless bridge to other, more advanced blockchains.
Unlike traditional bridges that rely on trusted custodians, the Grail bridge uses advanced ZK cryptography to secure transfers. This architecture leaves it far better protected against bridge hacks that have lost investors billions in the past, and far more trustworthy for the largest whales and institutions to enter the world’s first, real Bitcoin DeFi
Grail is already being integrated with major blockchains like Cardano, and has inspired its community to double down on becoming a Bitcoin DeFi Layer.

The $BOS Token: A Second Chance To Catch Bitcoin?
As BitcainOS prepares for its 2025 mainnet launch, attention is turning to its upcoming $BOS token presale – the so-called “gas token for Bitcoin compute.”
$BOS token holders will earn rewards for running SLAM nodes that stake $BOS tokens to participate in proof verification, and assist with multichain interactions. Users can use $BOS, BTC, or other tokens to directly pay for this computational activity.
This economic model ensures constant validation of cross-chain activity, and keeps Bitcoin and other chains coordinated, united, and secure at all times.
“The $BOS token creates a framework for trustless coordination between different blockchain environments,” explained Yago. “As all of crypto begins securing its activity on Bitcoin, the $BOS token’s value will rise in direct proportion to the overwhelming demand for Bitcoin block space and cross-chain activity.”
$BOS’s Bitcoin-centric economics could be appetizing for the crypto market today, which expert analysts note is increasingly consolidating around Bitcoin and BTC. Bitcoin market dominance is now above 60%, with outside ecosystems failing to keep pace with the original chain.

Getting Started with the Testnet
Users can begin exploring the Grail bridge testnet immediately:
- Visit the BitcoinOS website
- Obtain test BTC from the Bitcoin Testnet 3 faucet
- Connect a supported wallet (including OKX, Xverse, Unisat, Leather, BitGet, or any Wallet Connect-compatible wallet)
- Select a destination chain and execute the transfer
While current functionality focuses on one-way transfers to EVM chains, two-way bridging capabilities are in development and expected to launch with the mainnet. The team is also working to expand support beyond EVM to other major blockchain ecosystems.
The Road Ahead
The Grail testnet launch marks a significant milestone in BitcoinOS’s development roadmap. The project aims to enable mainnet transactions by the end of Q2 2025, coinciding with its token launch and broader ecosystem deployment.
For investors and crypto enthusiasts, the combination of working technology and upcoming token distribution represents a unique opportunity to participate in Bitcoin’s evolution. As BitcoinOS moves toward unifying the crypto ecosystem around Bitcoin, early supporters can engage through both testing and the upcoming presale.
“We’re bringing crypto home to Bitcoin,” said Yago. “With BitcoinOS, Bitcoin can finally fulfill its potential as both digital gold and a platform for unlimited decentralized innovation.”
With the crypto community increasingly focused on Bitcoin’s role in the ecosystem, BitcoinOS’s technological breakthroughs and approaching token launch suggest that a new chapter in Bitcoin’s story is about to unfold.
Those interested in participating in the $BOS token presale can register their interest at bitcoin.build. The project maintains active communities on Discord and Telegram where users can get support for testnet participation and stay updated on presale developments.
