Helios is a fast, trustless multichain light client for Ethereum written in Rust that turns an untrusted centralized RPC endpoint into a verified local RPC server. It syncs in seconds, requires no storage, and compiles to WebAssembly so it can be embedded in wallets and dapps.
Use cases
- run a trustless local ethereum rpc endpoint
- verify ethereum rpc responses without running a full node
- embed a light client in a crypto wallet
- sync to ethereum mainnet in seconds on mobile
- use a light client for op stack chains like base
- access linea chain data without trusting the rpc provider
- convert alchemy or infura into a verified local rpc
When to choose
- you need trust-minimized ethereum access without running a full node
- you're building a wallet or dapp that needs verified chain data
- you want a lightweight client that runs on mobile or in wasm
- you need to verify rpc data from untrusted providers like alchemy or infura
When to avoid
- you need a full archive node with historical state access
- you need chains outside ethereum, op stack, and linea
- you need high-throughput production rpc infrastructure for many users
- you require features beyond the rpc methods helios supports
