BOB has joined forces with LayerZero to unlock the access capabilities of native BTC across a multi-chain ecosystem with one click, covering nearly 15,000 Dapps across 11 chains including Ethereum, Avalanche, and BNB.

September 30 - BOB (Build on Bitcoin) announced the official launch of the first trustless one-click native Bitcoin cross-chain channel, connecting native Bitcoin with 11 on-chain institutional-grade wrapped Bitcoin (wBTC) issued by BitGo and supported by LayerZero.

This smooth interoperability system allows users to easily access native BTC through wBTC.OFT. At the same time, with the BOB Gateway SDK, nearly 15,000 Dapps across 11 mainstream chains, including Ethereum, Avalanche, Base, and BNB, can achieve one-click access to the immense liquidity and user base of native Bitcoin. Previously, most of these 11 mainstream public chain networks did not have direct paths to native BTC.

The BOB Gateway simplifies the complex cross-chain bridging process, enabling the direct conversion of native BTC, allowing users to more conveniently access the multi-chain DeFi ecosystem built around wBTC OFT. This integration is based on BOB's Bitcoin intent system and LayerZero's OFT standard, achieving secure, programmable, and composable cross-chain Bitcoin liquidity. The combination of Bitcoin intent and universal messaging constructs a highly capital-efficient interoperability model, marking another significant advancement following BOB's recent upgrade of wBTC to the LayerZero OFT standard.

The LayerZero wBTC.OFT standard is a full-chain (Omnichain) standard for implementing wrapped Bitcoin ( WBTC ), which allows WBTC to be transferred and interoperate seamlessly and efficiently across different blockchains. This standard is supported by LayerZero's cross-chain verification protocol and by custodians such as BitGo through a burn-mint mechanism, ensuring the liquidity and security of the assets and expanding the usage of WBTC to a broader blockchain ecosystem.

For institutions and individual users holding native BTC, the BOB Gateway supports one-click conversion of assets into wBTC.OFT on 11 chains (for example, for participating in DeFi deposits), or one-click return of earnings to native BTC. Additionally, nearly 15,000 Dapps on the 11 chains accessing wBTC.OFT can now achieve one-click native BTC deposit functionality through the integrated BOB Gateway SDK. This will greatly reduce the operational complexity of DeFi, allowing complex position management, including loop strategies, to be easily utilized by both institutions and retail investors, effectively promoting the large-scale application of Bitcoin in the DeFi world.

Nearly $2.3 billion worth of wBTC.OFT has completed 67,000 cross-chain transfers through LayerZero. After this upgrade, holders can directly convert native BTC to wBTC.OFT across chains, injecting new liquidity into the ecosystem and expanding access.

Alexei Zamyatin, co-founder of BOB and core contributor to BitVM, stated: “This upgrade is a key step in making BOB the Bitcoin DeFi gateway. By enabling instant access to wBTC.OFT through the BOB Gateway, we provide a convenient one-click integration native BTC entry solution for thousands of applications across 11 on-chain networks. This strategic move aligns closely with our core goal of enhancing BTC accessibility and providing a seamless, smooth user experience. As native BTC flows into wBTC.OFT through BOB, users will be able to earn yields on Bitcoin in DeFi more securely and conveniently.”

Simon Baksys, Vice President of Global Business Development at LayerZero, stated: “As a leading interoperability infrastructure, LayerZero enables applications and users to access the required assets on the desired chains. wBTC is currently one of the most widely used assets in the DeFi ecosystem, and this integration with BOB Gateway will further unleash its utility. By connecting native BTC to nearly 15,000 applications across 11 chains, we are very much looking forward to seeing wBTC continue to grow its market share as the most trusted asset in the crypto space and meet more user demands.”

In addition to Ethereum, Avalanche, Base, and BNB, the BOB Gateway also supports Soneium, Unichain, Bera, Optimism, Sei, TelosEVM, Swell, Sonic, and the native BTC and wBTC.OFT of the BOB chain for seamless two-way one-click conversion, covering a total of 11 mainstream public chains. This extensive multi-chain layout ensures that users and developers can enjoy one-click Bitcoin DeFi services within the mainstream ecosystem.
