Monad

Overview

Monad is a high-performance Ethereum-compatible L1 blockchain. Monad materially advances the efficient frontier in the balance between decentralization and scalability. Monad improvements address existing bottlenecks while preserving seamless compatibility for app developers (full EVM bytecode equivalence) and users (Ethereum RPC API compatibility).

Wallets Types

BitGo enables holding Monad in the following wallet types:

	Multisig Cold	Multisig Hot	MPC Cold	MPC Hot
Custody	❌	❌	✅	❌
Self-Custody	❌	❌	✅	✅

Ticker Symbols

Mainnet	Testnet
mon	tmon

Faucet

You can use a faucet to obtain free testnet Monad for development and testing purposes.

Units

Each Monad consists of 1,000,000,000,000,000,000 (10¹⁸) wei, so not even a single monad can be stored numerically without exceeding the range of JavaScript numbers. Gas fees use gwei.

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

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

Tokens

The Monad blockchain natively supports tokens.

Create Wallet

export BITGO_EXPRESS_HOST="<YOUR_LOCALHOST>"
export COIN="tmon"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export LABEL="<DESIRED_WALLET_NAME>"
export PASSPHRASE="<YOUR_BITGO_LOGIN_PASSPHRASE>"
export ENTERPRISE_ID="<YOUR_ENTERPRISE_ID>"

curl -X POST \
 http://$BITGO_EXPRESS_HOST/api/v2/$COIN/wallet/generate \
 -H 'Content-Type: application/json' \
 -H "Authorization: Bearer $ACCESS_TOKEN" \
  -d '{
    "label": "'"$LABEL"'",
    "passphrase": "'"$PASSPHRASE"'",
    "enterprise": "'"$ENTERPRISE_ID"'",
    "walletVersion": 4
}'

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

Create Address

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

curl -X POST \
-H "Authorization: Bearer $ACCESS_TOKEN" \
https://app.bitgo-test.com/api/v2/tmon/wallet/$WALLET/address

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

Consolidate Balance

Consolidation Fee Source: Monad Gas Tank Monad uses forwarders, so it does not support manual consolidation

Estimate Fee

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

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

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

Transact

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

let params = {
  recipients: [

      amount: "<AMOUNT_1>",
      address: "<DESTINATION_ADDRESS_1>",

  ],
  walletPassphrase: "<YOUR_WALLET_PASSPHRASE>",
};
wallet.sendMany(params).then(function (transaction) {
  // Print transaction details
  console.dir(transaction);
});

Stake

Staking is out of scope for these chains as they don’t have native support for them.
