House Party Protocol

Overview

House Party Protocol (HPP) is an AI-native Arbitrum Orbit Layer 2 blockchain secured by Ethereum. The network is fully EVM-compatible and uses AnyTrust data availability to deliver scalable, low-cost infrastructure for decentralized applications and autonomous agents.

Faucet

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

Units

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

  • 1 hppeth = 1018 wei
  • 1 wei = 10-18 hppeth
  • 1 gwei = 10-9 hppeth

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

Tokens

House Party Protocol natively supports ERC20 tokens. BitGo-supported House Party Protocol tokens can be accessed on the Mainnet (e.g. BitGo coins and tokens).

Fees

House Party Protocol supports EIP-1559 gas estimation. Fees consist of a base fee that adjusts dynamically based on block utilization plus an optional priority tip. As an Arbitrum Orbit chain, fees also include an L2 component for posting data to the parent chain. The network denominates and pays gas in ETH.

Create Wallet

bitgo
  .coin('thppeth')
  .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="thppeth"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export LABEL="<DESIRED_WALLET_NAME>"
export PASSPHRASE="<YOUR_BITGO_LOGIN_PASSPHRASE>"
export ENTERPRISE_ID="<YOUR_ENTERPRISE_ID>"

}'

Create Address

bitgo
  .coin('thppeth')
  .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>"

curl -X POST \

Consolidate Balance

Consolidation Fee Source: House Party Protocol Gas Tank

House Party Protocol 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 = 'thppeth';

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="thppeth"
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"

Transact

Withdrawal Fee Source: Wallet Base Address

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

export BITGO_EXPRESS_HOST="<YOUR_LOCALHOST>"
export COIN="thppeth"
export WALLET_ID="<YOUR_WALLET_ID>"
export ACCESS_TOKEN="<YOUR_ACCESS_TOKEN>"
export ADDRESS="<DESTINATION_ADDRESS>"
export AMOUNT="<AMOUNT_IN_BASE_UNITS>"
export WALLET_PASSPHRASE="<YOUR_WALLET_PASSPHRASE>"

curl -X POST \

  -H 'Content-Type: application/json' \
 -H "Authorization: Bearer $ACCESS_TOKEN" \
  -d '{
    "address": "'"$ADDRESS"'",
    "amount": "'"$AMOUNT"'",
    "walletPassphrase": "'"$WALLET_PASSPHRASE"'"
}'
