OP_NET has introduced a decentralized finance stack designed to run directly on Bitcoin’s base layer without relying on bridges, wrapped assets, or separate gas tokens. The platform uses standard Bitcoin transactions, allowing users to execute smart contracts with BTC as the only fee currency. The approach is described as “SlowFi,” reflecting Bitcoin’s slower block times and higher transaction costs compared to other networks.
Native Transactions and Taproot Integration
According to co-founder Frederic Fosco, applications operate through Taproot-based Bitcoin transactions. The system’s NativeSwap model enables token swaps without wrapping BTC or introducing additional tokens. Transactions typically cost between $1 and $2 under normal conditions, rising to $10–$20 during congestion, as users only pay standard network fees.
Debate Over Bitcoin’s Expanding Use Cases
The launch has intensified debate within the Bitcoin community. Supporters argue that on-chain DeFi activity could strengthen the network’s fee market, especially as mining rewards decline after halving events. Critics, however, warn that adding DeFi-style functionality may congest block space and shift Bitcoin away from its primary role as a monetary system.
Unlike alternatives such as RSK and Stacks, which rely on separate layers or tokens, OP_NET keeps execution fully on Bitcoin. The model targets users willing to trade speed for security and native asset usage.
