TechFlow news, May 22 — According to official announcements, OKX officially launched its wrapped Bitcoin asset xBTC on May 22, 2025, and simultaneously opened deposit and withdrawal services for three major public chains: Solana, Sui, and Aptos. With xBTC, users can seamlessly participate in multi-chain DeFi ecosystems, supporting on-chain functions such as lending and liquidity mining, further unlocking Bitcoin’s cross-chain liquidity and yield opportunities. Additionally, OKX Wallet will gradually launch yield-generating products around xBTC, integrating top-tier DeFi protocols from the Solana, Sui, and Aptos ecosystems, enabling users to access additional ecosystem incentives through one-stop operations. Stay tuned.
xBTC is a wrapped Bitcoin issued by OKX, strictly backed by a 1:1 reserve mechanism. Users can withdraw BTC from the exchange to their chosen blockchain and receive an equivalent amount of xBTC, or deposit xBTC back to the exchange via the target chain to redeem BTC. The platform ensures asset transparency and enhances user security through real-time on-chain Proof of Reserves (PoR) verification.
