Bob, a Bitcoin-first Layer 2 built on the OP Stack, now fully integrated as a Tier-1 blockchain by Dfns.
We're excited to announce that Bob is now fully integrated into the Dfns Wallet-as-a-Service platform as a Tier-1 blockchain. This means developers and institutions can now access all wallet and transaction capabilities on Bob securely, programmatically, and at scale.
What is Bob?
Bob is a high-performance Layer 2 rollup that brings Bitcoin to modern smart contract infrastructure. Built using the OP Stack and backed by Bitcoin's economic security, Bob enables developers to build Ethereum-style applications with native BTC support. Its goal: unify the liquidity, user base, and credibility of Bitcoin with the programmability and scalability of rollups.
Key features include:
- Bitcoin-first: Bob is the first rollup designed from the ground up for BTC-native assets and users.
- OP Stack compatibility: Developers can deploy EVM smart contracts with familiar tools and workflows.
- Modular architecture: Bob separates execution from consensus, leveraging Bitcoin for finality while enabling high-speed on-chain applications.
- Fast and developer-friendly: With low fees, fast finality, and a familiar dev environment, Bob lowers the barrier to building powerful Bitcoin-based dApps.
