API

Reading from the blockchain

import { eth_getBlockByHash } from "@ethernauta/eth";
import { reader, SEPOLIA_CHAIN_ID } from "./reader";

const readable = eth_getBlockByHash([
  "0x31386e6cfba70bb4d8a95404bdb740572b758a15c62e51ee912071a7b5be9e26",
  false,
]);
const block = await readable(reader(SEPOLIA_CHAIN_ID));

Signing a transaction

import { eth_sendRawTransaction } from "@ethernauta/eth"
import { number_to_hex } from "@ethernauta/wallet"

const method = "transfer"
const ADDRESS = "0x515e9e0565fdddd4f8a9759744734154da453585"
const params = [ADDRESS, number_to_hex(1)]
const signed_transaction = await window.wallet.sign(
  method,
  params,
)

Writting to the blockchain

import { transfer } from "@ethernauta/eth"
import { number_to_hex } from "@ethernauta/wallet"
import { writer, SEPOLIA_CHAIN_ID } from "./writer"

const writable = transfer([
  "0x636c0fcd6da2207abfa80427b556695a4ad0af94",
  number_to_hex(1),
])
const hash = await writable(writer(SEPOLIA_CHAIN_ID))
await writable(writer(SEPOLIA_CHAIN_ID))

Reacting to transaction states

import { transfer } from "@ethernauta/eth"
import { number_to_hex } from "@ethernauta/wallet"
import { writer, SEPOLIA_CHAIN_ID } from "./writer"
import {
  watch_transaction,
  register_transaction
} from "@ethernauta/transaction"

const writable = transfer([
  "0x636c0fcd6da2207abfa80427b556695a4ad0af94",
  number_to_hex(1),
])
const hash = await writable(writer(SEPOLIA_CHAIN_ID))
// initial transaction state 
// with "type" key equal "pending"
const transaction = register_transaction(hash)
watch_transaction(hash, (transaction) => {
  // subsequent states that the transaction goes trough
})
