Philosophy

This module aims to be an un-opinionated representation of the defined:

• JSON-RPC 2.0 specification

Modules

• eth
• wallet
• connector
• transport
• transaction

Examples

Creating reader

import { eip155_11155111 } from "@ethernauta/chain"
import {
  create_reader,
  encode_chain_id,
  http,
} from "@ethernauta/transport"

const NAMESPACE = {
  ETHEREUM: "eip155",
}
const ETHEREUM_SEPOLIA_RPC_URL =
  "https://grounded-electronic-house.ethereum-sepolia.quiknode.pro/4d40a4c7ec139649d4b1f43f5d536c3756faacc9/"
export const SEPOLIA_CHAIN_ID = encode_chain_id({
  namespace: NAMESPACE.ETHEREUM,
  reference: eip155_11155111.chainId,
})
export const reader = create_reader([
  {
    chainId: SEPOLIA_CHAIN_ID,
    transports: [http(ETHEREUM_SEPOLIA_RPC_URL)],
  },
])

Creating a writer

import { eip155_11155111 } from "@ethernauta/chain"
import {
  create_writer,
  encode_chain_id,
  http,
} from "@ethernauta/transport"

const NAMESPACE = {
  ETHEREUM: "eip155",
}
const ETHEREUM_SEPOLIA_RPC_URL =
  "https://grounded-electronic-house.ethereum-sepolia.quiknode.pro/4d40a4c7ec139649d4b1f43f5d536c3756faacc9/"
export const SEPOLIA_CHAIN_ID = encode_chain_id({
  namespace: NAMESPACE.ETHEREUM,
  reference: eip155_11155111.chainId,
})
export const writer = create_writer([
  {
    chainId: SEPOLIA_CHAIN_ID,
    transports: [http(ETHEREUM_SEPOLIA_RPC_URL)],
  },
])
