tBTC Meets Sui: Liberating Bitcoin from Digital Vaults
Threshold and Sui have announced a major integration to bring tBTC, the leading decentralized Bitcoin asset, to the Sui blockchain, engineered for mass adoption. This collaboration unlocks access to over $500 million in Bitcoin liquidity for Sui’s high-performance DeFi ecosystem, known for its near-zero fees, sub-second finality, and exceptional capital efficiency.
Threshold Network’s tBTC is a decentralized, trust-minimized onchain version of Bitcoin that preserves Bitcoin’s core principles while enabling liquidity across DeFi ecosystems. Now live on Sui, tBTC empowers users to trade, lend, and engage in advanced DeFi strategies within a secure, scalable environment, with transaction finality as fast as 400 milliseconds.
Sui will be the first non-EVM chain to support direct minting on the Threshold app, expanding accessibility and reinforcing its position as a premier destination for Bitcoin liquidity. On Sui, tBTC can participate in DeFi strategies within a high-speed, scalable environment—from trading and lending to more specialized use cases, such as serving as collateral on protocols like Bucket, while preserving its core properties.
“Bitcoin was designed to be used, not locked away,” says Callan “Sap” Sarre, Co-founder and CPO at Threshold Labs. “With tBTC on Sui, we’re combining the security of threshold cryptography with a high-throughput network to create a new standard for Bitcoin utility.
The integration will expand Sui’s growing Bitcoin ecosystem across four Sui-native protocols:
- Bluefin: Trade tBTC across select pairs and unlock additional APR rewards.
- Bucket: Save, spend, and explore Bitcoin-powered DeFi with ease.
- AlphaLend: Access advanced lending pairs and APR% rewards by supplying tBTC.
- AlphaFi: Enable high-leverage BTC DeFi strategies with auto-looping vaults.
Additionally, users can also mint tBTC directly on Sui via the Threshold dApp, providing a secure and easy access point to BTCFi. Key benefits of tBTC on Sui include:
- Sub-Second Finality: Transactions complete in 400 milliseconds.
- Eliminate Fragmentation: Move Bitcoin seamlessly between protocols with near-zero fees.
- True Sovereignty: No reliance on centralized custodians.
- Web3 Power, Web2 UX: Fast, cheap, and user-friendly.
Lastly, Wormhole will serve as the key interoperability provider for tBTC’s expansion to the Sui network. A dedicated bridge enabling users to move tBTC from other networks to Sui will soon be available on the Portal website. This integration will streamline cross-chain activity, making it easier for users to access Bitcoin DeFi across various ecosystems, including Sui, Ethereum, and others.
“We’re excited to support Bitcoin’s growth on Sui through Wormhole’s cross-chain infrastructure,” said Robinson Burkey, Co-Founder of Wormhole. “This integration advances Bitcoin’s interoperability and unlocks new DeFi opportunities while preserving the security and decentralization users expect.”
Enhanced Bitcoin DeFi Experience
Bitcoin DeFi is thriving on Sui, with a significant portion of Sui’s TVL now composed of BTC-backed assets. Since February 2025, a substantial amount of Bitcoin volume has flowed into Sui-native protocols. The integration of tBTC will strengthen this ecosystem by:
- Unlocking seamless Bitcoin liquidity on Sui through direct tBTC minting.
- Supporting leveraged DeFi strategies without compromising decentralization.
- Delivering frictionless DeFi interactions backed by industry-grade infrastructure.
As the world’s most valuable digital asset gains momentum and utility, Bitcoin expands beyond serving as a store of value to power decentralized finance (DeFi) applications.
Strategic Three-Month Campaign
To support the launch of Threshold’s tBTC on Sui, Threshold and Sui are kicking off a three-month campaign to facilitate long-term adoption. The initiative includes protocol-level developer support and ecosystem-wide activations to ensure the Bitcoin Standard flourishes in modern DeFi applications. This also includes limited-time incentives on select Sui DeFi Protocols, namely Bucket, AlphaLend, and Bluefin.
“BTC is expected to bring a massive amount of Bitcoin liquidity to Sui, creating a bridge that truly matters for institutions and everyday people who love Bitcoin,” said Adeniyi Abiodun, Co-Founder and Chief Product Officer at Mysten Labs, the original contributors to Sui. “This integration opens another door to accessible, sovereign BTCfi participation.
