Threshold Network and Sui have integrated tBTC, a decentralized Bitcoin-backed asset, onto the Sui blockchain, unlocking access to over $500 million in Bitcoin liquidity within Sui's high-performance DeFi ecosystem.

Sui’s object-centric design simplifies smart contract interactions, enhancing security and making audits more straightforward.

The launch is supported by a three-month campaign focused on developer support and ecosystem activation, including incentives for protocols like Bucket, AlphaLend, and Bluefin.

Sui is a scalable Layer 1 blockchain optimized for speed, security, and rich asset support, built with the Move programming language for fast and private digital asset ownership.

Sui emphasizes speed and liquidity as key advantages over competitors, positioning itself as a leading chain for Bitcoin DeFi applications.

tBTC on Sui offers benefits such as near-zero fees, no reliance on custodians, and a user-friendly Web2-like experience despite being built on Web3 infrastructure.

This development facilitates new trading and DeFi strategies, including Bitcoin perpetuals, delta-neutral loops, and retail access to advanced DeFi tactics.

The integration aims to boost Bitcoin on-chain liquidity, improve market depth, reduce spreads, and increase fee revenue for Sui.

Four native protocols—Bluefin, Bucket, AlphaLend, and AlphaFi—are already utilizing tBTC for vaults, lending, and leveraged strategies, treating tBTC as high-quality collateral.

Wormhole will serve as the interoperability bridge, enabling cross-chain movement of tBTC between Sui and networks like Ethereum, enhancing Bitcoin DeFi accessibility and liquidity.

The security of tBTC is strengthened by threshold cryptography, enabling Bitcoin holders to earn yield securely without custodial risks.

tBTC on Sui allows users to trade, lend, and implement advanced DeFi strategies with transaction finality as fast as 400 milliseconds, leveraging Sui's scalability and low fees.
