## What is House Party Protocol

House Party Protocol (HPP) is an Ethereum layer 2 network built on Arbitrum Orbit and aimed at AI and data applications. It is the successor of the Aergo blockchain, whose AERGO token migrates to the HPP token at a 1:1 ratio.

## Network and consensus

| Parameter | Details |
|---|---|
| Type | Ethereum layer 2 network built on Arbitrum Orbit, EVM-compatible. |
| Runs on | Three layers: HPP Mainnet (Arbitrum Orbit L2), Ethereum (settlement, L1) and the legacy AERGO Mainnet. |
| Launched | HPP Public Mainnet went live on 18 August 2025. |
| Smart contracts | HPP Mainnet chain ID 190415; gas is paid in ETH. |
| Consensus | The legacy Aergo layer 1 uses DPoS consensus and Lua smart contracts; its network went live in April 2019. |

## Supply and issuance

| Parameter | Details |
|---|---|
| Maximum supply | Hard cap of 1,700,000,000 HPP with no inflationary issuance. |
| Initial distribution | Supply vests over 80 months; allocations are held in separate vaults with third-party custodians. |
| Issuance | 76% of newly issued HPP is allocated to community-focused initiatives. |
| Staking rewards | Staking runs in seasons of about three months with a seasonal APR model. |
| Initial distribution | Migration: 1 AERGO = 1 HPP; 1 AQT = 7.43026 HPP via the migration portal. |

## What HPP is used for

- Gas and fees for layer 2 transactions, AI executions and API calls.
- Staking and delegation by validators and data providers.
- Governance through token-weighted voting.
- Buying, selling and licensing datasets and AI models in the ecosystem.

## Who develops and governs House Party Protocol

- **Governance**: HPP DAO decides protocol upgrades, treasury use and governance rules; execution is left to operational entities.
- **Governance**: Protocol decisions go through HPP Agora, the on-chain DAO launched in April 2026.
- **Developer**: HPP is co-developed with Aergo, Alpha Quark (AQT), Booost and VaaSBlock.
- **Open source**: GitHub organisation hpp-io, created 2 April 2025.

## History

| Date | Event |
|---|---|
| 2019 | Aergo launched as an enterprise-focused hybrid blockchain. |
| February 2024 | The Aergo core team began a review of the project's positioning and long-term direction. |
| April 2025 | The community approved AIP-21, adopting the House Party Protocol name and the merged ecosystem. |
| — | The Aergo team thanked the community after AIP-21 passed and said it would build the layer 2 first. |
| — | AIP-22 proposed moving HPP's layer 2 from OP Stack to Arbitrum's stack. |
| 18 August 2025 | HPP Public Mainnet went live. |
| April 2026 | HPP Agora, the on-chain DAO, launched. |

## Security and audits

- HPP says its contracts were audited by CertiK and its reserves are held in BitGo institutional custody.
- In April 2025 a DDoS attack made the Aergo website temporarily unavailable; the team reported it back online and warned of impersonation scams.

## Security incidents

| Date | What happened | Source |
|---|---|---|
| 14 April 2025 | Outage: A DDoS attack made the Aergo website temporarily unavailable; Aergo later said the site was fully back online and warned users about impersonation and scam DMs. No loss of funds was stated. | [x.com](https://x.com/i/status/1911684243530616856) |

## Official HPP contracts

| Network | Contract address |
|---|---|
| Ethereum | [0xe33fbE7584EB79e2673abe576B7AC8C0De62565c](https://etherscan.io/token/0xe33fbE7584EB79e2673abe576B7AC8C0De62565c) |

HPP token contracts as published in the HPP docs. The legacy AERGO ERC-20 contract is 0x91af0fbb28aba7e31403cb457106ce79397fd4e6 (https://etherscan.io/token/0x91af0fbb28aba7e31403cb457106ce79397fd4e6).

## Risks and caveats

- Holders of legacy AERGO and AQT must swap to HPP; HPP warns users to check contract addresses to avoid loss of funds.
- Token allocations vest over 80 months, so circulating supply grows over time.
- Staking rewards follow a seasonal model whose rules can change each season.
