Bitcoin adoption on Sui gains momentum with Threshold Network and Sui starting the second phase of integrating tBTC, a popular Bitcoin sidechain project.

Bitcoin adoption on Sui is expanding as Threshold Network and Sui progress with Phase 2 of tBTC integration.

In an exciting development for the decentralised finance (DeFi) landscape, Phase 2 of tBTC on Sui has been announced. This phase includes the launch of auto-optimising yield strategies, such as the AlphaFi Auto-Looping Vault, and expanded liquidity options for tBTC on Sui.

One of the key features of this phase is the introduction of the AlphaFi Auto-Looping Vault, which can be tried out at https://alphafi.xyz/portfolio/ALPHALEND-SINGLE-LOOP-TBTC. This innovative strategy aims to optimise yield for users, making it easier for them to earn returns on their tBTC holdings.

In addition to the AlphaFi Auto-Looping Vault, new tBTC pool pairs have been launched on Bluefin. These pool pairs, including the tBTC-USDC pair available at https://trade.bluefin.io/deposit/0x1f121fb96bb1f57ac07564e7fad3a0412a6958701da1a66496b70f7ea15e051e, are designed to enhance composability across BTC assets and strengthen Bluefin's position as a key liquidity venue in Sui's growing BitcoinFi ecosystem.

The bridge for tBTC from the Ethereum Network to Sui is now live at https://sui.threshold.network/. This bridge enables users to move their tBTC assets between the two networks, further increasing the liquidity and utility of tBTC on Sui.

Sui is a Layer 1 blockchain and smart contract platform designed to make digital asset ownership fast, private, secure, and accessible. Based on the Move programming language, Sui is emerging as a new hub for BitcoinFi, with Bitcoin-backed lending, trading, and yield strategies. For more information about Sui, visit https://sui.io.

The launch of Phase 2 of tBTC on Sui has been facilitated by a partnership between Threshold Network, the protocol behind tBTC, and a growing community of builders on Sui. This partnership was announced jointly by Threshold Network and the Sui community.

The tBTC x Sui Phase 2 brings the launch of key new infrastructure for leveraged yield and seamless cross-chain flow, expanding Bitcoin's role in DeFi on Sui. With Bitcoin DeFi assets now accounting for over 20% of Sui's Total Value Locked (TVL), the market is ready for tBTC in Sui, with $10M supplied on Alphalend and thousands of community participants, moving beyond the experimental stage.

This development is a significant step forward for both the tBTC and Sui ecosystems, confirming measurable progress in BitcoinFi and offering cross-chain access, structured yield products, and more capital-efficient strategies. tBTC has found a product-market fit on Sui, as demonstrated by Phase 1, where Bitcoin liquidity scaled rapidly when provided with the right environment. Sui is one of the first non-EVM networks to recognise the growing need for users to unlock Bitcoin utility on-chain.
