tBTC Integration Brings Bitcoin Liquidity to Sui

Threshold’s tBTC now live on Sui, enabling Bitcoin holders to access DeFi while unlocking over $500M in liquidity.

tBTC Launch on Sui Enables Native Bitcoin Access to DeFi

The integration of Threshold Network’s tBTC into the Sui Blockchain marks a significant advancement in bridging Bitcoin’s liquidity with decentralized finance infrastructure. This development allows Bitcoin holders to mint tBTC—a tokenized, 1:1 backed version of Bitcoin—directly on the Sui Network, making their BTC interoperable within Sui's fast-growing DeFi ecosystem.

What is tBTC?

tBTC is a decentralized, non-custodial version of Bitcoin on Ethereum and now, on Sui. Backed 1:1 by BTC and secured through threshold cryptography, tBTC allows users to maintain custody-free exposure to Bitcoin while utilizing it across DeFi protocols. Unlike centralized wrapped Bitcoin alternatives, tBTC minimizes reliance on third-party custodians by distributing trust across a network of independent signers.

Why This Matters for Sui

The arrival of tBTC on Sui introduces the potential for over $500 million in Bitcoin liquidity to be utilized in Sui-native protocols. It opens up opportunities for Bitcoin holders to access staking, lending, liquidity provisioning, and yield-generating strategies without moving assets outside of their Sui wallet.

According to Adeniyi Abiodun, Co-Founder and Chief Product Officer at Mysten Labs, the original contributor to Sui:

“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. This new integration opens another door to accessible, sovereign BTCFi participation.”

BTCFi: Expanding Bitcoin’s Utility

The emergence of BTCFi—short for Bitcoin DeFi—aims to expand Bitcoin’s role from a passive store of value to an active capital asset within decentralized applications. By leveraging tBTC on a performant network like Sui, users gain access to high-throughput, low-latency DeFi use cases without compromising on decentralization.

Sui has already seen promising adoption: over 600 BTC (approximately $65 million) have been bridged into the ecosystem since February 2025. BTC-backed assets now represent more than 10% of the total value locked (TVL) on Sui, which currently exceeds $1.83 billion, according to DeFiLlama.

Secure, Scalable Bitcoin Integration

Threshold Network, which supports tBTC, is a decentralized protocol combining cryptographic primitives with blockchain infrastructure. It leverages threshold cryptography, a technique where private keys are divided among multiple parties, reducing the risk of single-point failure. This approach ensures a secure, trust-minimized mechanism for bridging Bitcoin into other blockchain ecosystems.

Callan Sarre, Co-Founder at Threshold Labs, emphasized:

“Bitcoin was designed to be used, not locked away. With tBTC coming on Sui, we’re combining the security of threshold cryptography with a high-throughput network to create a new standard for Bitcoin utility.”

As of July 2025, tBTC has a market capitalization exceeding $570 million, with over 5,265 tBTC tokens in circulation, according to CoinGecko.

Conclusion

The integration of tBTC into Sui represents a pivotal development in the evolution of BTCFi. It unlocks substantial liquidity for DeFi applications while maintaining the decentralization ethos of Bitcoin. For Sui, it signals increasing maturity as a multi-asset ecosystem capable of attracting cross-chain capital and serving as a foundational layer for next-generation decentralized finance.
