With BitGo’s WBTC now live on Sui, Bitcoin holders can move a unified cross-chain asset seamlessly across ecosystems. Learn how to migrate and use WBTC on Sui.
Main Takeaways
WBTC is now live on Sui in the LayerZero-powered OFT standard, enabling instant, gas-only cross-chain transfers and unified liquidity.BitGo’s WBTC is already supported across major Sui DeFi platforms, including AlphaLend, Aftermath, Bluefin, Bucket, Cetus, Momentum, Navi, Suilend, and STEAMM.The OFT format makes WBTC easier to move and build with, giving Bitcoin a smoother path into Sui’s fast, low-fee DeFi and BTCfi ecosystem.
Overview
Wrapped Bitcoin (WBTC) is now native to Sui in the OFT (Omnichain Fungible Token) format, giving Bitcoin ($BTC ) holders a smoother and more consistent way to bring liquidity into Sui’s fast, low-cost DeFi and BTCfi ecosystem.
Secured by BitGo and powered by LayerZero, WBTC can move seamlessly across supported chains, arriving on Sui ready for use in swaps, lending markets, yield strategies, and new BTC-driven products.
This creates a simpler, more direct path for Bitcoin holders to tap into Sui’s high-performance infrastructure and the growing set of protocols building on it.
What Is WBTC (How the OFT Standard Works)
WBTC is a tokenized form of BTC that can be used on blockchains beyond the Bitcoin network.
Each WBTC is backed 1:1 by BTC held in custody by BitGo, a regulated institutional qualified custodian, ensuring the supply is fully reserved. This gives Bitcoin holders a simple way to use their assets in faster, more expressive environments like Sui.
On Sui, WBTC is now natively available thanks to the OFT format, which BitGo uses to keep the asset unified across all blockchains. Transfers are fast, cost only normal gas fees, and avoid additional wrapping or conversion steps. Everything moves 1:1 with no slippage, ensuring predictable cross-chain transfers.
LayerZero provides the connectivity, while BitGo continues to secure the underlying Bitcoin and maintain the token contracts across supported chains, allowing WBTC to move smoothly between ecosystems and into Sui’s expanding BTCfi landscape.
What the OFT Standard Unlocks
With WBTC now natively available on Sui through the OFT standard, users gain a consistent and much simpler cross-chain experience.
Instead of managing different versions of the asset or dealing with fragmented liquidity, WBTC behaves the same wherever it’s supported.
This gives users confidence that their token will work predictably across applications and provides builders with a unified source of Bitcoin liquidity to develop on.
The result is a smoother experience: users can move WBTC freely, and developers can rely on a single, widely supported version of BTC when designing new products.
How to Bring WBTC Into Sui: Migration Instructions
Moving WBTC into Sui is straightforward, whether you currently hold WBTC on Ethereum or previously accessed it through the Sui native bridge. 
The steps below outline the simplest path to receive WBTC on Sui in the unified OFT format, now natively deployed by BitGo. 
For users with WBTC on Ethereum
If you already hold WBTC on Ethereum, you can transfer it directly into Sui in OFT format:
Visit Stargate.Select Ethereum as your source chain and Sui as your destination.Choose WBTC as your asset.Enter the amount you’d like to move and confirm the transaction.
After a short confirmation period, your WBTC will appear in your Sui wallet in OFT format.
For users who brought WBTC into Sui using the Sui native bridge
If you used the Sui native bridge in the past to bring WBTC into Sui, follow these steps:
Use the Sui native bridge to send your WBTC back to Ethereum.Once your WBTC arrives on Ethereum, visit Stargate.Select Ethereum → Sui, choose WBTC, and complete the transfer.
This ensures your WBTC arrives on Sui in the unified OFT format used across supported ecosystems.
Where You Can Use WBTC on Sui
With BitGo bringing WBTC toSui in OFT format, users can start exploring a range of DeFi applications that support Bitcoin liquidity. The previously bridged version of WBTC on Sui was limited to the Sui network, whereas the OFT format connects Sui to broader Bitcoin liquidity across all supported LayerZero-enabled chains. 
Ecosystem teams are now shifting toward the OFT-based version for new pools and integrations. This gives builders and liquidity providers a clearer, more flexible foundation for supporting WBTC across Sui.
Trading and liquidity: Aftermath, Bluefin, Cetus, Momentum, and STEAMM are among the Sui DeFi platforms now integrating WBTC into their trading routes and liquidity pools. Users can swap WBTC for other assets directly on Sui or provide liquidity in pools that include WBTC pairs as they go live across the ecosystem.
Borrowing and collateral: AlphaLend, Bucket Protocol, Navi, and Suilend all support (or are rolling out support for) WBTC within their borrowing and collateral markets, enabling users to use WBTC across Sui’s lending ecosystem
More coming soon: Additional integrations — including lending markets and new BTCfi-focused products — are already in development. Teams will share updates as support continues to expand.
Why This Matters for BTCfi on Sui
The arrival of WBTC marks an important milestone for Sui’s BTCfi ecosystem. 
With a unified, widely supported version of Bitcoin now available on-chain, builders have a stable foundation to design BTC-powered applications without managing fragmented liquidity or multiple token variants.
For users, this introduces a straightforward way to bring Bitcoin into Sui and interact with the network’s fast, low-fee infrastructure. For developers and market participants, it creates a dependable source of BTC liquidity that can support trading, collateral markets, new asset primitives, and future BTCfi innovations.
As more teams integrate WBTC across their protocols, Bitcoin becomes easier to use throughout the Sui ecosystem, helping strengthen liquidity and expand opportunities.
