Bitcoin is moving closer to native decentralized finance as OpNet goes live on mainnet, introducing smart contract functionality that enables yield-generating strategies directly on the network.
Launched Thursday, the protocol allows users to engage in DeFi activities such as trading, lending and staking without moving their bitcoin off-chain. All interactions are executed as standard Bitcoin transactions, with BTC used as the only fee token.
Until now, Bitcoin holders have largely been excluded from DeFi’s core ecosystem, which has been dominated by smart contract platforms like Ethereum. Access typically required workarounds such as wrapping BTC, using cross-chain bridges or relying on custodial services—each introducing additional risks and undermining Bitcoin’s self-custody model.
OpNet aims to eliminate those barriers by enabling applications to run natively on Bitcoin’s base layer. Users can connect their wallets directly to DeFi platforms and retain full control of their assets throughout.
According to OpNet, the protocol embeds smart contract logic into Bitcoin transactions, which are then validated by miners. This approach ensures that execution and state remain anchored to the network’s core infrastructure.
The launch includes a native DeFi stack on Bitcoin layer 1, supporting permissionless smart contract deployment with a focus on trading, yield generation and token issuance. Developers can issue assets using the OP-20 standard and build applications that settle directly on Bitcoin.
Among the first live applications is MotoSwap, a decentralized exchange that enables swaps between BTC and OP-20 tokens. It features a two-step execution model tailored to Bitcoin’s slower block times, along with staking tools that allow users to create yield opportunities.
OpNet also embraces Bitcoin’s slower transaction speeds as a feature rather than a limitation. The team argues that longer block intervals and higher fees during congestion create natural friction, encouraging liquidity to remain within protocols for longer periods.
This concept, referred to as “SlowFi,” is designed to support more stable and sustainable DeFi activity, reducing the rapid inflows and outflows often seen on faster blockchains.
Looking ahead, the OpNet team plans to introduce stablecoin functionality through the OP-20S standard in early Q2 2026, a move expected to further expand the scope of Bitcoin-native DeFi.
