tBTC is now on Sui: A New Standard for Decentralized Bitcoin Utility

Today, we're thrilled to announce that BTC is now an accessible bridge to DeFi on one of the most powerful layer-one chains in crypto: Sui, a high-performance, composable blockchain infrastructure. This new access point for BTC holders marks a fundamental shift in how Bitcoin can participate in DeFi ecosystems: combining Bitcoin's security with 400 milliseconds transaction finality.

An Unlikely Alliance: Hard Money x Fluid Experience

At first glance, avid Bitcoin users and Sui ecosystem builders may appear to represent different ends of the blockchain spectrum—one rooted in the principles of sound money and decentralization, the other focused on pushing the boundaries of user experience and blockchain scalability. Yet it is precisely this contrast that makes their collaboration so compelling. The convergence of Bitcoin’s monetary integrity with Sui’s high-performance infrastructure will create a uniquely powerful foundation for the next phase of decentralized finance.

Sui, the only blockchain built for mass adoption, offers an unmatched combination of scalability, speed, and composability of assets. While other chains often compromise on speed or decentralization, Sui has engineered an environment where high performance coexists with user trust. With support for 297,000 TPS and 400ms finality, Sui will provide the environment needed to transform BTC into active capital.

tBTC will bring Bitcoin's multi-trillion-dollar liquidity to a deeply integrated DeFi network through its multi-layered architecture. Unlike centralized wrapped tokens that compromise Bitcoin's core principles, tBTC works for everyone. Institutions achieve compliance, while Bitcoin maximalists maintain their sovereignty. This integration will activate Bitcoin's utility across multiple Sui-native DeFi protocols, including Bluefin, Bucket, AlphaLend, and AlphaFi, while providing users with a variety of ways to utilize their Bitcoin.

“tBTC is expected to bring a massive amount of Bitcoin liquidity to Sui, creating a bridge that truly matters—not just for institutions but for everyday people who love Bitcoin,” said Adeniyi Abiodun, Co-Founder and Chief Product Officer at Mysten Labs, the original contributors to Sui. “This new integration opens another door to accessible, sovereign BTCfi participation.”

Both tBTC and Sui share a fundamental vision: challenging the false polarity between performance and decentralization. Sui achieves this through its innovative object-centric model that minimizes coordination costs. tBTC accomplishes this through its decentralized and trust-minimized approach to Bitcoin on DeFi. Together, they will represent not merely a technical integration but a reimagining of what decentralized finance was always meant to be.

“Bitcoin was designed to be used, not locked away,” said Callan “Sap” Sarre, Co-founder at Threshold Labs. “With tBTC on Sui, we will combine the security of threshold cryptography with a high-throughput network to create a new standard for Bitcoin utility.”

Strategic Convergence for Next-Gen Bitcoin DeFi

This launch marks the beginning of a comprehensive three-month campaign supported by an alliance of ecosystem leaders committed to building a sustainable Bitcoin DeFi ecosystem on Sui:

1. Sui: Delivering strategic support and technical infrastructure to enable sustainable Bitcoin utility throughout the Sui ecosystem.
2. Bluefin: Acting as the primary DEX partner, powering deep tBTC liquidity and efficient trading across key trade pairs.
3. AlphaFi: Unlocking leveraged yield opportunities for tBTC through auto-looping vaults built for risk-adjustable strategies.
4. AlphaLend: Facilitating tBTC lending and borrowing, empowering users to earn yield or access liquidity while maintaining full Bitcoin exposure.
5. Bucket: A collateralized debt platform that allows users to leverage tBTC as collateral to unlock onchain liquidity.

Sui is set to become the first non-EVM chain to support direct tBTC minting via the Threshold app, broadening access and strengthening its role as a leading destination for Bitcoin liquidity. A growing suite of DeFi applications is unlocking new utilities for BTC, from trading and lending to using tBTC as collateral on protocols like Bucket. Together, these innovations are transforming BTC from a dormant store of value into a fluid, productive asset with long-term yield potential.
