Today, Threshold Network announced the launch of tBTC on Starknet, bringing the Bitcoin asset into its DeFi ecosystem. Summary tBTC: Starknet’s DeFi welcomes Bitcoin The layer-2 zk-rollup Starknet Threshold Network tBTC: Starknet’s DeFi welcomes Bitcoin tBTCaims to be the main decentralized asset backed 1:1 by Bitcoin within the layer-2 of Starknet. This will expand multi-chain access to Bitcoin, and make Threshold a more accessible decentralized Bitcoin bridge. The arrival of tBTC on Starknet opens new native DeFi opportunities concerning Bitcoin. The integration with Starknet allows the direct minting of tBTC through the Threshold interface. This way, users can deposit Bitcoin and access the DeFi ecosystem of Starknet. The objective is to strengthen the position of tBTC as a decentralized and widely accessible wrapped Bitcoin solution across multiple networks. Furthermore, such an approach lays the groundwork for potential advanced Bitcoin DeFi strategies, including, for example, automated yield vaults, liquid BTC staking tokens, and composable lending solutions that uphold Bitcoin’s decentralized principles. Thanks to tBTC, operational on eight blockchains, Threshold Network has created the most comprehensive decentralized Bitcoin bridge infrastructure possible. The multi-chain presence of tBTC allows users to access Bitcoin’s DeFi opportunities, maintaining custody and mitigating the risks of centralization. The layer-2 zk-rollup Starknet The integration with Starknet is a strategic expansion of zero-knowledge rollup technology. It combines the security of Bitcoin with advanced scalability solutions, so by leveraging the high processing capacity and low fees of Starknet, tBTC users can adopt sophisticated DeFi strategies without compromising decentralization or security. In fact, Starknet Foundation is a decentralized and permissionless ZK-rollup based on Ethereum, which offers high scalability, low fees, and rapid finality. Based on STARK proofs, and developed by StarkWare, it is designed to offer long-term composability, security, and flexibility for developers. Threshold Network Threshold Network is a decentralized protocol that combines cryptographic primitives and on-chain infrastructure to support permissionless applications. It is managed by Threshold DAO and Threshold Labs, and it is based on tBTC, one of the wrapped tokens of Bitcoin. The collaboration with Starknet is the eighth blockchain integration of tBTC. The integration will be initiated with two key partners of the ecosystem, providing immediate functionality to tBTC users. The first is Ekubo, which is the main decentralized exchange of Starknet, that will offer high liquidity through trading pairs. The second is Vesu, the main lending protocol of Starknet, which will allow users to obtain loans against their investments in tBTC. The idea is to mirror the successful adoption patterns on the Ethereum mainnet, where 25% of the tBTC supply is locked in Aave, demonstrating a strong demand for Bitcoin-backed loans. The partnership will prioritize long-term sustainability over short-term incentives, focusing on meaningful use cases and the growth of the protocol. For this reason, Threshold Network has committed incentives to contribute to the start of the Starknet ecosystem, and to maintain its momentum beyond the initial launch phase. The CEO of Threshold Labs, MacLane Wilkison, commented by saying: “tBTC offers a decentralized and trust-minimized bridge for Bitcoin on Starknet, allowing native BTC liquidity to flow securely in a ZK-rollup environment. This integration promotes a multi-chain future where Bitcoin functions as programmable capital, securely distributed across scalable, composable, and censorship-resistant networks”.
