[email protected] device

The EVM consensus light client

About

The [email protected] device is an EVM/Ethereum consensus light client built into the HyperBEAM devices stack. With helios, node operators can trustlessly connect to EVM RPCs with a very lightweight, multichain and secure setup, and no historical syncing overhead. With this device, every hyperbeam node can turn into a verifiable EVM RPC endpoint.

What is Helios?

Helios is a trustless, efficient, and portable multichain light client written in Rust.

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.

[email protected] device

The [email protected] as per its current implementation, initiates the helios client (and JSON-RPC server) at the start of the hyperbeam node run. The JSON-RPC server is spawned as a separate process running in parallel behind the 8545 port (standard consensus rpc port).

The device supports all of the methods supported by helios. Check the full list here

Endpoint

As this device is supported on the hb.load.rs hyperbeam node, it's explicitly assigned the eth.rpc.rs endpoint for the Ethereum mainnet network.

Example

local

curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' http://127.0.0.1:8545

using rpc.rs

curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_blockNumber","params":[],"id":1}' https://eth.rpc.rs
