BOB is a hybrid L2 that combines EVM and Bitcoin infrastructure. Through Blast's custom and public APIs, BOB developers have instant access to essential blockchain data, to build on the intersection of Bitcoin and Ethereum and drive innovation and experimentation.
BOB ("Build on Bitcoin") is a Layer-2 that combines the advantages of Bitcoin and Ethereum. By leveraging the security, liquidity, user base, and innovation from both blockchain ecosystems, BOB bridges the gap between Bitcoin's mass adoption potential and Ethereum's innovation potential. BOB's rollup ecosystem uses Bitcoin for security while allowing users to access dApps, stablecoins, NFTs, DeFi options, through Ethereum's EVM. BOB brings together the benefits of Bitcoin (user base, adoption, liquidity, market cap, and PoW security) with Ethereum's innovation know-how (EVM, smart contracts, self-custody Web3 wallets). BOB launches on the OP stack, enabling rollups to Ethereum for seamless onboarding of users, assets, and liquidity. Additionally, BOB can inherit Bitcoin security through a novel merged mining protocol (re-staking for Bitcoin). At its core, BOB utilizes the Ethereum Virtual Machine (EVM) to create and execute smart contracts, primarily developed in Solidity. The EVM version on BOB is similar to Ethereum's, ensuring compatibility with existing developer tools, wallets, top multisig solutions, and key infrastructure, including block explorers and data analytics platforms.
Public RPC Endpoint
Public WSS Endpoint
Returns the number of the most recent block
Core API
Blast custom APIs offer optimized throughput and reduced latency for transactions on BOB and enable access to real-time data, transaction history and network status.
Included with all plans
Debug API
The Debug API gives Blast L2 developers access to several non-standard RPC methods, which will allow them to inspect, debug and set certain debugging flags during runtime.
Included with Developer, Startup, Enterprise & Pay As You Go plans
Archive Nodes
These nodes retain all historical transaction information on the Blast L2 blockchain from the genesis block to the present, enabling users to query and retrieve any past information.
