MegaETH

Overview

MegaETH is an Ethereum Layer 2 blockchain designed for real-time performance, targeting 100,000 transactions per second with 10-millisecond block times. It uses a single high-performance sequencer that holds the entire blockchain state in memory, enabling transaction execution without storage I/O. MegaETH is fully EVM-compatible, allowing existing Ethereum dApps to deploy without code modifications. The network uses ETH as its native gas token.

Units

Each MegaETH unit is comprised of 1,000,000,000,000,000,000 (10¹⁸) wei, so not even a single ETH can be stored numerically without exceeding the range of JavaScript numbers. Gas fees are denoted in gwei.

1 ETH = 10¹⁸ wei
1 wei = 10^-18 ETH
1 gwei = 10^-9 ETH

For that reason, only string balance properties are available, which are balanceString, confirmedBalanceString, and spendableBalanceString.

Tokens

MegaETH natively supports tokens. BitGo-supported MegaETH tokens can be accessed on the Mainnet (e.g. BitGo coins and tokens).

Fees

MegaETH supports EIP-1559 gas estimation. The network uses ETH as its native gas token for transaction fees. Fees consist of a base fee that is burned and an optional priority tip paid to the sequencer. The base fee adjusts dynamically based on block utilization.

Create Wallet

bitgo
  .coin('tmegaeth')
  .wallets()
  .generateWallet({
    label: 'My Test Wallet',
    passphrase: 'secretpassphrase1a5df8380e0e30',
    enterprise: '5612c2beeecf83610b621b90964448cd',
    walletVersion: 4,
  })
  .then(function (wallet) {
    // print the new wallet
    console.dir(wallet);
  });

export BITGO_EXPRESS_HOST="<YOUR_LOCALHOST>"
export COIN="tmegaeth"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export LABEL="<DESIRED_WALLET_NAME>"
export PASSPHRASE="<YOUR_BITGO_LOGIN_PASSPHRASE>"

Create Address

bitgo
  .coin('tmegaeth')
  .wallets()
  .getWallet({ id: '585c51a5df8380e0e3082e46' })
  .then(function (wallet) {
    return wallet.createAddress();
  })
  .then(function (newAddress) {
    // print new address details
    console.dir(newAddress);
  });

export WALLET="585c51a5df8380e0e3082e46"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"

Consolidate Balance

Consolidation Fee Source: MegaETH Gas Tank

MegaETH uses forwarders, so it does not support manual consolidation.

Estimate Fee

const BitGoJS = require('../../../src/index.js');
const bitgo = new BitGoJS.BitGo({ env: 'test' });
const accessToken = '<YOUR_ACCESS_TOKEN>';
const coin = 'tmegaeth';

async function getFeeEstimate() {
  try {
    await bitgo.authenticateWithAccessToken({ accessToken });
    const res = await bitgo.coin(coin).feeEstimate({ numBlocks: 2 });
    console.dir(res);
  } catch (err) {
    console.error('Error fetching fee estimate:', err);
  }
}

getFeeEstimate();

export COIN="tmegaeth"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"

curl -X GET \
 https://app.bitgo-test.com/api/v2/$COIN/tx/fee \
 -H 'Content-Type: application/json' \

Transact

Withdrawal Fee Source: Wallet Base Address

const tx = await fundedWallet.send({
    address: '<DESTINATION_ADDRESS>',
    amount: '<AMOUNT>',
    walletPassphrase: process.env.PASSWORD,
  });
