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](https://www.gobob.xyz/) 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 onchain 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.

### DFNS unlocks Tier-1 status for Bob

Our Tier-1 integration with Bob offers seamless wallet functionality through the DFNS API, including:

- Automatic asset detection: Instantly view Bob-based assets in every wallet. No manual setup.
- Transfer history: Keep track of all Bob transactions for compliance, reporting and user experience.
- Transaction management: Sign and send Bob transactions securely, with full audit logging and multi-tenant controls.
- Webhook notifications: Subscribe to real-time balance updates and transaction events to build responsive apps and services.

With DFNS, developers can now build on Bob trading apps, tokenization platforms, cross-chain services, payment flows, and any financial use case bridging Bitcoin with modern smart contracts.
