Bitcoin holders now have even more powerful tools at their disposal—thanks to the launch of xBTC, a new exchange-native BTC asset introduced by OKX, now live on the Sui Blockchain. As Bitcoin-backed assets continue to surge across Web3, Sui stands out with one of the most robust and rapidly growing Bitcoin DeFi (BTCfi) ecosystems in the space.
By launching xBTC on Sui, OKX signals a strong endorsement of Sui’s high-performance infrastructure, which combines security, speed, and scalability—critical traits for unlocking the next wave of Bitcoin utility in DeFi.
Why Sui? A Top-Tier Choice for xBTC
Sui is one of just three blockchain networks globally selected for xBTC’s debut, cementing its place as a prime venue for Bitcoin DeFi. Users can mint xBTC directly on the OKX exchange and withdraw it seamlessly to any on-chain wallet—including the native OKX Wallet—as a native Sui asset.
Two of Sui’s leading DeFi platforms—Cetus and Navi Protocol—are serving as exclusive launch partners for xBTC integration, ensuring immediate access to trading, liquidity, and yield strategies.
“At OKX, we’re constantly innovating to support onchain growth and decentralized finance,” said Jason Lau, Chief Innovation Officer at OKX. “Our reputation for trust and transparency strengthens the security model behind xBTC, and we’re excited to extend this new asset into Sui’s dynamic BTCfi ecosystem.”
Unlocking New Bitcoin Liquidity on Sui
The integration of xBTC doesn’t just expand token offerings—it also opens new reward mechanisms and liquidity paths for DeFi users. With xBTC backed by one of the world’s most trusted crypto exchanges, Sui is quickly solidifying its role as the most BTCfi-diverse Layer 1 blockchain.
And the numbers back it up. Since February, nearly 600 BTC have moved into the Sui ecosystem. BTC-backed assets now account for over 10% of the network’s total value locked (TVL)—a testament to the increasing interest from Bitcoin holders seeking secure, high-throughput chains for on-chain finance.
A Thriving BTCfi Arsenal on Sui
xBTC joins an expanding list of BTC-based assets on Sui, including WBTC, LBTC, and sBTC—each tailored for different use cases and risk preferences, ranging from fully decentralized custody models to exchange-issued convenience. This comprehensive suite of options gives users the flexibility to choose the BTCfi path that fits their strategy.
“Bitcoin DeFi on Sui has rapidly evolved from a novel idea into a fully validated market,” said Christian Thompson, Managing Director at the Sui Foundation. “OKX’s decision to deploy xBTC on Sui demonstrates the strength and maturity of our BTCfi infrastructure—and it’s another milestone in bringing Bitcoin into the heart of DeFi.”
Sui: Becoming the BTCfi Capital of Web3
The arrival of xBTC follows a wave of high-profile Bitcoin DeFi integrations on Sui, including Stacks, Lombard, Babylon, Cubist, SatLayer, and RedStone—each helping to build a full-stack BTCfi ecosystem. From custody to collateralization and lending to staking, Sui is fast becoming the destination of choice for Bitcoin utility in DeFi.
Whether you're a Bitcoin holder seeking new earning opportunities or a DeFi user looking for innovative BTC-backed instruments, Sui and OKX’s xBTC offer a secure, efficient gateway to a new era of Bitcoin finance.
