Bitcoin is the most secure and decentralized asset, but using it across different networks has always been slow and frustrating. Bridging can take hours, while wrapped assets, like wBTC, introduce security risks. Combined, these challenges isolate Bitcoin from the flourishing ecosystems that your users enjoy using.
It doesn’t have to be this way.
Today, we’re excited to launch native Bitcoin support in the OneBalance Toolkit, enabling instant Bitcoin-to-EVM token swaps in partnership with Turnkey and Reservoir. With one compact SDK, apps can now integrate Bitcoin into their core offering, creating a seamless, one-click experience and unlocking new possibilities for their users.

Making Bitcoin transactions instant
Despite Bitcoin’s massive $1.9t market cap, less than 2% ($24.5b+) is actively used outside the Bitcoin network via wrapping, restaking, or locked within Bitcoin Layer 2s. This highlights an enormous untapped opportunity for apps to unlock deep Bitcoin liquidity and grow their total-value-locked (TVL) with the OneBalance Toolkit.
Through the OneBalance Toolkit, our Chain Abstraction solution, apps can transform complex multichain interactions into seamless, one-click user experiences.
This allows for:
- Gas fee abstraction
- Multichain portfolio aggregation
- Instant crosschain swaps
- Passkey signing
- Transaction batching
- Multichain call data functionality (Useful for NFT marketplaces, money markets, and Perp DEXs)
For native Bitcoin, EVM networks, and soon Solana, in the same account.

What makes this possible and sets OneBalance apart from our competition is that we leverage Resource Locks to make instant cross-chain transactions possible—even for slower networks like Bitcoin. They work by temporarily locking the assets on the source chain–also known as creating a credible commitment. This provides a guarantee to solvers that they will always get paid, and there is no risk of double-spend. Solvers then fulfill the transaction instantly on the destination chain, bypassing both tedious finality waiting periods and slow bridging times.
This isn’t just a speed upgrade. It fundamentally shifts how Bitcoin interacts with other chains and apps.
Made possible with Turnkey and Reservoir
We couldn’t bring Bitcoin to the OneBalance Toolkit without the support of Turnkey and Reservoir. Turnkey provides the trusted execution environment (TEE) and policy-based controls, enabling our Toolkit to ensure secure authentication and a seamless signing UX for Bitcoin accounts. Meanwhile, Reservoir is the solver, facilitating order fulfilment and ensuring efficient execution for crosschain Bitcoin transactions.
The future of Chain Abstraction
Growing onchain fragmentation requires infrastructure that gives users simplicity. The OneBalance Toolkit does this by abstracting away the complexity of cross-chain interactions to allow your users to hold a single balance and execute transactions across supported chains.
We are in closed beta, with several GTM teams backed by Cyber Fund, Binance Labs, and Consensys already building on our infrastructure. Whether you're a new spot or perp DEX, payment solution, or something brand new; enable BTC for your users.
