tBTC Native Minting on Arbitrum is now live

Today, Threshold DAO has launched its first cross-chain native minting experience for tBTC users on Arbitrum. If you’ve been looking to leverage Bitcoin’s power in the thriving Ethereum Layer 2 ecosystem, this launch offers a seamless, user-friendly solution. With innovative UI upgrades, direct minting capabilities, and no need for a separate Ethereum Layer 1 transaction, users can now efficiently mint tBTC natively on Arbitrum.

This isn’t just another integration—it’s a leap forward from the leading decentralized Bitcoin bridge, empowering you to tap directly into the Arbitrum ecosystem with the security and decentralization of Bitcoin. Whether you’re a developer building on this advanced infrastructure or a DeFi user seeking rewards and incentives, the new tBTC minting experience opens doors to new possibilities in DeFi.

The tBTC Native Minting Dapp on Arbitrum is powered by an off-chain relayer and the tBTC SDK extension to Arbitrum. The off-chain relayer coordinates transactions between chains so that users can directly mint tBTC on Arbitrum. The relayer is maintained by Threshold DAO members through governance. It is powered by Wormhole, a long-standing Threshold DAO partner with whom we expanded tBTC to leading Layer 2 chains last year (Arbitrum, Base, Optimism, Polygon), as well as Solana. The tBTC SDK extension for Arbitrum empowers developers to build native minting directly into their Dapps across the Arbitrum ecosystem. For more details, check out the tBTC SDK documentation on how to start building.

This launch, along with its innovative UI and core technology, introduces a loyalty program for tBTC liquidity providers. The program rewards participants not only for their involvement but also for their long-term commitment. Points are assigned based on your weighted average liquidity across Curve and Uniswap V3 pools on Arbitrum. The more liquidity you provide, the more rewards you’ll claim.

Threshold DAO teamed up with the Arbitrum grants program to create a series of incentive buckets:

• 20,000 ARB + $45k in Threshold’s T token for tBTC on GMX incentives 
• 50,000 ARB + 25% in T for long-term liquidity providers of tBTC on Arbitrum
• Ongoing Threshold Incentives for liquidity pools on Curve and Uniswap on Arbitrum

This launch comes at a timely moment, with many DeFi protocols on Arbitrum including GMX, Synthetix and Notional proposing to list tBTC. Stay tuned for updates on these deployments.

In the meantime, head over to the native minting Dapp. Mint tBTC natively on Arbitrum. Earn your share of rewards. Yes, there’s even a leaderboard, so happy degening!
