Helios converts an untrusted centralized RPC endpoint into a safe unmanipulable local RPC for its users. It syncs in seconds, requires no storage, and is lightweight enough to run on mobile devices. Helios has a small binary size and compiles into WebAssembly. This makes it a perfect target to embed directly inside wallets and dapps. Installing First install heliosup , Helios's installer: To install Helios, run heliosup . Usage Ethereum To run Helios on Ethereum, run the command below, replacing $ETH RPC URL with an RPC provider URL such as Alchemy: $ETH RPC URL must be a supported Ethereum Execution API Provider that provides the eth getProof endpoint. We recommend using providers like Alchemy or Infura. Helios will now run a local RPC server at http://127.0.0.1:8545 . Helios also provides documentation of its supported RPC methods in the rpc.md file. OP Stack To run Helios on an OP Stack chain, run the command below, replacing $ETH RPC URL with an RPC provider URL such as Alchemy and $NETWORK with a supported OP Stack network: Currently supported network values are op-mainnet and base , with more to come soon. Linea To run Helios on Linea, run the command below, replacing $ETH RPC URL with an RPC provider URL such as Alchemy: $ETH RPC URL must be a supported Ethereum Execution API Provider that provides the eth getProof endpoint.
