HAPI Protocol

What HAPI Protocol Is

HAPI Protocol is an on-chain and off-chain cybersecurity solution designed to bring institutional-grade threat intelligence directly into decentralized finance. Rather than relying on users to manually verify counterparties, HAPI embeds security checks at the smart contract layer so DeFi protocols can automatically screen wallets against a continuously updated database of known malicious addresses, compromised accounts, and stolen funds before any transaction completes.

The core problem HAPI addresses is a structural gap in DeFi security: when a centralized exchange is hacked or a wallet is flagged for money laundering, there is no on-chain mechanism that prevents stolen funds from moving freely through decentralized protocols. HAPI fills that gap by distributing real-time threat intelligence across integrated protocols, enabling coordinated, trustless responses to emerging threats.

How the Core Mechanism Works

HAPI operates through two integrated layers. The on-chain layer consists of smart contracts deployed across multiple blockchains that maintain a publicly queryable registry of flagged addresses, categorized by risk type and assigned ban periods ranging from twelve hours to permanent. DeFi protocols integrate these contracts directly and query them before executing user transactions.

The off-chain layer handles data sourcing and processing. HAPI's oracle network—a distributed set of nodes, each running an independent oracle service—collects threat intelligence from external data providers, including established blockchain analytics firms, and relays it to the on-chain registry. According to the protocol's documentation, the defining characteristic of HAPI-specific oracles is speed: threat data must reach smart contracts faster than attackers can move funds, which makes latency the primary design constraint rather than the price accuracy that dominates traditional DeFi oracles.

Data providers supply information to the network and are selected through a DAO governance process. Node operators who contribute threat data receive compensation in HAPI tokens. Requests to modify or add address data carry a fee, creating an economic layer that discourages low-quality or fraudulent submissions.

When a new threat event occurs—such as a confirmed exchange hack—HAPI distributes the flagged wallet addresses across all integrated protocols simultaneously. Any integrated DeFi application can then reject deposits or interactions from those addresses, interrupting the movement of stolen funds before they are laundered through decentralized liquidity pools or token swaps.

Key Products and Features

HAPI Terminal is the protocol's primary interface for security professionals and integrators. It provides real-time address monitoring, transaction path visualization to trace fund flows, and smart contract vulnerability detection. HAPI Labs cybersecurity specialists conduct manual investigations on a case-by-case basis for complex threats that require human analysis beyond automated detection.

Scamfari is a crowd-sourcing cybersecurity platform developed under the HAPI Foundation that enables community members to submit reports on scams, phishing sites, and malicious projects. Submissions are evidence-backed and go through a validation process before contributing to the shared threat database. Scamfari 2.0 expanded the platform into a multi-level system that combines community reporting with AI-powered analysis to automate data collection, validation, and decision-making at scale.

HAPI ID is a Web3 digital identity tool designed to distinguish genuine human users from automated bots. Its primary application is ensuring that ecosystem rewards—airdrops, governance distributions, and liquidity mining programs—reach verified participants rather than Sybil attackers operating multiple wallet addresses.

HAPI Snap for MetaMask extends the protocol's security layer to individual users by integrating directly with the MetaMask browser extension. It aggregates threat data and applies AI processing to flag potentially risky on-chain actions before users confirm transactions.

Supported Blockchains

HAPI Core, the foundational set of smart contracts, is deployed across multiple networks. The Solana implementation is built on the Anchor framework and maintained in the HAPIprotocol GitHub repository, where it has accumulated over 500 commits. The protocol also maintains EVM-compatible deployments and an implementation on NEAR Protocol. The native HAPI token exists as both an ERC-20 on Ethereum and a BEP-20 on BNB Chain. On the Solana network, HAPI additionally operates Boca Chica, a token launchpad. External data partnerships include Chainalysis and Crystal Blockchain as upstream intelligence sources.

Security and Audit Status

The HAPI Protocol has undergone security reviews by both CertiK and Hacken. CertiK has assigned the protocol a security rating of 4.0. The Hacken audit report is publicly available on Etherscan for the ERC-20 token contract.

Team and History

HAPI was launched in early 2021 and conducted its initial token offering through DAO Maker. The HAPI token was listed on AscendEX in July 2021. Development and ongoing coordination of the protocol are managed by the HAPI Foundation, which describes its mission as uniting cybersecurity approaches aligned with Web3 principles.

Fit in the Solana Ecosystem

Within Solana, HAPI provides a security primitive that DeFi protocols can integrate to screen user wallets before transactions execute. As the Solana ecosystem has expanded to encompass significant total value locked across lending markets, automated market makers, and derivatives platforms, the attack surface for theft and money laundering has grown correspondingly. HAPI's oracle infrastructure offers protocols a mechanism to connect to cross-chain threat intelligence, so a wallet flagged on Ethereum following an exchange hack can be blocked on Solana-native DeFi without any manual intervention by the protocol team. The Anchor-based HAPI Core implementation aligns with the standard development tooling used across Solana's smart contract ecosystem, reducing integration friction for teams that want to add address screening to their contract logic.
