OKX Introduces xBTC on the Aptos Network for Bitcoin-Backed DeFi

OKX Launches xBTC on Aptos, Transforming Bitcoin Usage in DeFi

On May 22, 2025, the Aptos Foundation announced the successful launch of xBTC on the Aptos network, a major step forward in integrating Bitcoin with decentralized finance (DeFi) applications. This new token is a wrapped version of Bitcoin that is fully backed 1:1 by BTC held in custody by OKX, one of the leading cryptocurrency exchanges.

Seamless Integration for Users

Aptos users can mint xBTC easily on the OKX platform without incurring any minting or redemption fees. Once minted, users are free to deposit or withdraw xBTC on the Aptos network, granting access to a multitude of DeFi applications that include trading, lending, and various Web3 strategies. This launch shows a commitment to enhancing usability and promoting broader access to decentralized finance options for Bitcoin holders.

A significant campaign is set to kick off on May 23 at 3 PM (UTC +8), in collaboration with industry leaders such as Hyperion, Echo Protocol, and Aries Markets. This partnership is positioned to drive deeper integrations within the Aptos ecosystem in the following weeks.

Enhancing Bitcoin's Utility in DeFi

Bitcoin is widely regarded as the most reliable cryptocurrency; however, it has seen limited engagement within smart contract ecosystems. The introduction of xBTC changes this narrative by enabling BTC holders to engage with DeFi on the Aptos network, which is designed as a scalable Layer 1 infrastructure capable of accommodating billions of users.

With a collateralization level of 1:1 and transparent custody facilitated by OKX’s public proof-of-reserves platform, xBTC not only boosts the usability of Bitcoin but also upholds the security and transparency that users demand. This shift is pivotal for the transition to open finance applications, as it strategically positions Bitcoin at the forefront of both traditional and decentralized finance.

A Thriving Ecosystem with Room for Growth

The Aptos platform currently hosts a robust DeFi ecosystem with over $1 billion locked in total value. Notable initiatives, such as aBTC through Echo Protocol, underscore the increasing momentum behind wrapped Bitcoin assets, with almost $270 million in TVL. With the arrival of xBTC, additional liquidity and cross-chain interoperability are anticipated, creating smoother access to DeFi protocols throughout the Aptos ecosystem.

As the DeFi sector continues to expand, initiatives like xBTC will play a vital role in the ongoing evolution of decentralized finance, giving developers the confidence and tools required to capitalize on these new opportunities.
