# BOB > The Bank of Bitcoin BOB is a hybrid Layer 2 network that combines Bitcoin security with Ethereum compatibility. It lets users swap, save, earn, and borrow using native Bitcoin across decentralized applications. BOB is a hybrid Layer 2 network, positioned as the Bank of Bitcoin, that combines Bitcoin proof-of-work security with Ethereum Virtual Machine compatibility. It operates as a rollup that draws finality from both Bitcoin and Ethereum, enabling swapping, saving, earning, and borrowing on Bitcoin rails. It targets Bitcoin holders and developers seeking access to decentralized finance without leaving Bitcoin's security guarantees. The network addresses the fragmentation of Bitcoin liquidity across many wrapped-asset bridges by using a native, trust-minimized bridge secured through cryptographic proofs rather than custodians. It functions as a hybrid rollup, combining optimistic verification with zero-knowledge fault proofs, and checkpoints its state to the Bitcoin network alongside settlement on Ethereum. This architecture lets users move native Bitcoin into decentralized applications while retaining a security model rooted in Bitcoin. BOB's ecosystem centers on a cross-chain swap and deposit gateway, alongside lending, staking, and yield products that let users earn on Bitcoin holdings. The platform supports a range of decentralized applications spanning trading, lending, and payments across multiple connected networks. It is used by Bitcoin holders, decentralized finance participants, and developers building applications that require native Bitcoin liquidity and shared settlement. - Type: Network - Sector: Blockchain Platforms - Status: Active - Founded: 2023-09-01 - Profile: https://thegrid.id/profiles/bob ## Products - [BOB Mainnet](https://thegrid.id/profiles/bob): BOB Mainnet is a hybrid rollup that combines Bitcoin security guarantees with Ethereum Virtual Machine compatibility. It settles transaction proofs while checkpointing state to Bitcoin and inherits additional security from a Bitcoin-secured fraud-proof bridge design, allowing native Bitcoin to be used directly in smart contracts without a wrapped intermediary. Developers deploy standard EVM smart contracts on the network, and users access decentralized applications, staking, and lending services built on top of it through a dedicated web application. (L2, Live, Main Product) - [BOB Fusion](https://thegrid.id/profiles/bob): BOB Fusion was a points distribution program that allocated rewards based on on-chain activity such as decentralized finance participation, liquidity provision, and other ecosystem engagement across multiple seasons. It tracked user actions on BOB Mainnet and converted qualifying activity into points redeemable for token rewards. The program has concluded and is no longer accepting new activity. (Customer Engagement Platform, Discontinued) - [BOB Gateway](https://thegrid.id/profiles/bob): BOB Gateway is a cross-chain infrastructure protocol that enables one-click, non-custodial swaps between native Bitcoin and stablecoins, tokenized gold, or wrapped Bitcoin across a range of blockchain networks. It uses an intents- and request-for-quote-based architecture with an on-chain Bitcoin light client, routing user swaps to competing solvers who settle atomically so that neither the application nor the protocol ever custodies funds. Wallets, exchanges, and decentralized applications integrate the underlying software development kit and API to add native Bitcoin interoperability, including direct exchange deposits and hardware wallet support, without building their own swap infrastructure. (Cross-chain Infrastructure, Live, Main Product) ## Assets - [BOB (BOB)](https://thegrid.id/profiles/bob): BOB is the utility and governance token of the BOB hybrid Bitcoin Layer 2 network. It is used for staking to secure Hybrid Nodes, participating in DAO governance decisions, and accessing priority allocation and fee discounts within the ecosystem. Its fixed supply of ten billion tokens is distributed across BOB Mainnet, Ethereum, and BNB Smart Chain, bridged canonically through Chainlink CCIP.
