HAPI Protocol

HAPI Protocol is a decentralized cybersecurity infrastructure layer for the blockchain ecosystem, offering real-time AML screening, on-chain address risk scoring, and compliance-grade tooling to DeFi protocols, exchanges, and wallets across multiple networks including Solana, Ethereum, BNB Chain, Polygon, and NEAR Protocol.

The Problem HAPI Solves

DeFi's permissionless design creates a persistent security gap: any wallet can interact with any protocol, regardless of its history of fraudulent activity, involvement in hacks, or association with money laundering. Traditional compliance tools built for centralized finance cannot plug into on-chain smart contracts. HAPI was designed to bridge that gap — making it possible for protocols to query the risk profile of a wallet address before processing a transaction, and for investigators to trace funds across complex transaction paths.

How It Works

HAPI operates as both an on-chain and an off-chain system. The on-chain component is a publicly accessible, smart-contract-based database of malicious wallet addresses that any DeFi protocol or wallet can query in real time via API or direct contract call. The off-chain component aggregates data from a range of sources — including major blockchain intelligence providers such as Chainalysis and Crystal Blockchain — alongside HAPI Labs' internal analysis and community-contributed reports, to continuously update and maintain that database.

At the core of the oracle architecture, independent node operators each run an oracle service that provisions off-chain data to HAPI smart contracts. Aggregating contracts evaluate this incoming data based on node performance and behavior, while reputation contracts penalize tampering. Addresses are categorized across four risk tiers — low, medium, high, and severe — based on transaction history and known associations with illicit activity.

This architecture allows DeFi protocols to embed HAPI's risk-scoring logic directly, screening counterparty wallets before a swap, deposit, or liquidity action executes.

Product Suite

HAPI offers a tiered product lineup accessed through its API or the HAPI Terminal software platform.

HAPI Protocol API is the foundational access layer. The free plan supports 500,000 requests per month at 600 requests per minute. The Business plan scales to 25 million requests per month at 100,000 requests per minute, designed for high-throughput integrations by exchanges and large DeFi protocols.

HAPI Terminal Lite ($150/month) bundles the Business API plan with five tools: On-chain Risk Scoring, Aggregated Audits Database, Branching Transaction Visualizer, Risk Assessing Suite, and Automated Risk Alerts, along with access to an OSINT database.

HAPI Terminal ($450/month) adds two more capabilities on top of the Lite package: Crowdsourced Data Aggregation (Scamfari) and the Automated Token Security Auditor.

The individual tools within these tiers each address a distinct slice of the security workflow:

• Aggregated Audits Database consolidates audit reports from crypto projects and generates automated compliance checks against smart contracts without requiring a formal audit. It also compares the current on-chain state of a contract against its audit report to flag divergence.
• Branching Transaction Visualizer constructs interaction graphs that enable users to trace the chronological movement of assets across multiple networks, saving investigations for ongoing monitoring.
• Risk Assessing Suite maintains a regularly updated database of wallet risk profiles, covering address changes and transaction chain histories.
• Liquidity Pool Monitoring provides early detection of suspicious activity in pools, enabling faster incident response.
• Automated Token Security Auditor evaluates tokens against 23 defined criteria to produce a risk categorization with continuous monitoring of subsequent changes.
• Scamfari is a crowdsourced reporting layer — an on-chain mechanism through which external agents contribute structured intelligence about malicious activity across networks. HAPI stakers can submit and validate reports, contributing to the database while earning rewards.
• HAPI ID is a more recent product, launched in October 2024, which extends the protocol's identity and reputation scoring into Web3 identity use cases, with a staking and referral program introduced in early 2025.

According to figures published on the HAPI website, the protocol has identified over 239,000 affected users in its database, serves more than 171,000 API requests per day, and has completed 159 or more formal investigations.

Token

The native HAPI token underpins the community participation layer of the protocol. Token holders can stake HAPI to participate in the Scamfari crowdsourced reporting system, submitting reports on malicious addresses and earning rewards for verified contributions. A referral program for HAPI stakers was opened to the public in early 2025. The token is a relatively small-cap asset, reflecting HAPI's position as infrastructure-layer tooling rather than a consumer-facing DeFi product.

Team and Background

HAPI Protocol was founded in 2021 and is operated by a team of more than 40 professionals. The named leadership includes Yurii Olentir (Co-Founder and CEO), Andrei Arsenin (CTO), Eugene Pshenychkin (COO), Vadym Prykhodko (Chief of Business Development), and Mark Letsyuk (Chief Communications Officer).

Notable protocol integrations and partnerships include Allbridge, Jumbo Exchange, RiskSwap, and Bitcoin.com's Verse DEX. In November 2025, HAPI partnered with BeanBee AI, an AI-powered DeFi copilot on BNB Smart Chain, to provide automated smart contract vulnerability checks running 25 checks in seconds as a built-in safety layer inside the BeanBee Telegram interface.

Solana Relevance

HAPI's oracle network and address scoring infrastructure extend to Solana alongside four other supported chains. Solana-based DeFi protocols, DEXes, and wallets can integrate HAPI's risk API to screen wallet addresses and token contracts, and Solana transactions are indexed within the Branching Transaction Visualizer for cross-chain fund tracing. As Solana's DeFi ecosystem has grown and attracted more security-focused builders, infrastructure layers like HAPI that offer compliance tooling compatible with the chain's high-throughput environment address an increasingly practical integration need.
