On Sui, Bitcoin holders have more choices than ever before. As BTC-backed assets grow increasingly popular in Web3, Sui is building the most comprehensive BTCfi infrastructure and asset matrix. Today marks the official launch of xBTC—a flagship BTC asset natively issued by OKX—further strengthening this asset ecosystem.

Sui is one of only three major public blockchains to support xBTC at launch, leveraging its secure, high-speed, and scalable environment to simplify user access to Bitcoin DeFi. xBTC can be minted directly on the OKX exchange and withdrawn as a native asset to any chain-compatible wallet, including the OKX Wallet. Two leading DeFi protocols in the Sui ecosystem, Cetus and Navi, will serve as exclusive initial partners for the xBTC rollout.

Jason Lau, Chief Innovation Officer at OKX, said: “At OKX, we continuously introduce new features that drive on-chain growth and support decentralized finance. As one of the most trusted and transparent institutions, we bring a robust security model to xBTC and are thrilled to bring it into Sui’s thriving Bitcoin finance ecosystem.”

The launch of xBTC opens a wide range of yield-generating strategies for Sui users and introduces a new liquidity channel backed by one of the world’s most trusted exchanges, further solidifying Sui’s position as the most diverse Layer 1 for BTCfi.

Sui’s BTCfi Momentum Remains Strong

Since February, nearly 600 BTC have flowed into Sui, driven by the network’s rich selection of assets and DeFi opportunities, making Sui the top choice for Bitcoin holders seeking secure on-chain DeFi access. BTC-backed assets now represent over 10% of Sui’s total value locked (TVL), a figure that continues to rise rapidly.

The addition of xBTC strengthens Sui’s growing suite of BTC assets, which already includes WBTC, LBTC, and sBTC—each offering distinct models, integration methods, and on-chain advantages. These options span from fully decentralized custodial solutions to familiar exchange-issued assets, covering the full spectrum of user needs—all accessible on Sui.

Christian Thompson, Head of the Sui Foundation, said: “Bitcoin DeFi on Sui has evolved from an intriguing idea to a proven product-market fit in just months. OKX choosing to bring xBTC to Sui is a strong validation of the strength and maturity of Sui’s BTCfi ecosystem, marking another key milestone in enabling deeper DeFi participation for Bitcoin holders on Sui.”

The arrival of OKX and xBTC is just one of several key BTCfi integrations on Sui recently, alongside others such as Stacks, Lombard, Babylon, Cubist, SatLayer, and RedStone—all collectively positioning Sui as the preferred platform for unlocking value from Bitcoin assets.
