🟢Project Introduction

Huma Finance is the first PayFi network that provides instant liquidity for cross-border payments and credit financing through Solana blockchain and stablecoin tokenized accounts receivable and other real-world assets. The platform provides high returns (10.5-25% APR) for retail and institutional investors, has processed more than $3.8 billion in transaction volume, and has worked with Solana, Circle, and Fireblocks to lead the way in connecting Web2 and Web3 financial systems.

🔵Product Composition

Huma's products are divided into three parts:

1. Huma 2.0 (no permission required): a decentralized platform where retail investors can deposit USDC into the liquidity pool and earn 10.5% APR. The fund allocation is 80% PayFi assets and 20% DeFi protocols.

2. Huma Institutional: a licensed service for institutional investors, requiring KYC/KYB, providing credit opportunities based on accounts receivable, such as cross-border payments and credit card settlements.

3. Arf: A Swiss licensed subsidiary, focusing on cross-border payment financing, providing short-term USDC loans to licensed payment institutions, secured by fiat currency.

🟤Technical architecture analysis

Huma's PayFi technology stack is divided into six layers, taking into account scalability, security and compliance:

1. Transaction layer (Solana): Solana provides 400 millisecond transaction confirmation and low fees of $0.00025, supporting high-frequency payment financing needs.

2. Currency layer (USDC, PYUSD): Stablecoins eliminate price volatility risks, and USDC's compliance enhances trust and interoperability.

3. Custody layer (Fireblocks, Cobo): Fireblocks provides enterprise-level security to resist hacker attacks; Cobo's multi-party computing (MPC) wallet improves fund security.

4. Compliance layer (Chainalysis, Elliptic): Chainalysis conducts anti-money laundering monitoring, and Elliptic ensures transparent fund flows and reduces regulatory risks.

5. Financing layer (Huma protocol): Huma's proprietary protocol fragments accounts receivable into token assets, and smart contracts automate loan issuance, repayment, and profit distribution.

6. Application layer (Arf, Raincard): Arf provides cross-border payment financing, and Raincard supports T+0/T+1 credit card settlement to build a seamless ecosystem.

🟢Core advantages and highlights

- High throughput and low cost: Solana's infrastructure enables Huma to process a large number of transactions at a low cost, far exceeding Swift (3-6 days, 1-3% fee).

- Stable income: Huma's 10.5-25% APR comes from real cash flow (6-10 basis points per day), avoiding the leveraged income risk of DeFi.

- Compliance: Arf's Swiss FINMA license and Chainalysis integration provide Huma with a competitive advantage in regulated markets.

- Modular stack: The open PayFi architecture encourages third-party application development, similar to Ethereum's Layer 2 framework, to promote ecological growth.

🔵Current barriers and optimization solutions

1. Insufficient off-chain transparency:

- Problem: Arf's risk management and borrower review are off-chain operations, which raises trust concerns.

- Solution: Increase transparency by disclosing anonymized borrower data on the chain or using zero-knowledge proofs to verify collateral, and increase third-party audits (such as Huma Institutional's PwC audit).

2. Regulatory risks:

- Problem: US regulation of stablecoins may limit market expansion.

- Solution: Deepen cooperation with compliant stablecoin providers such as Circle, expand to Singapore, UAE and other regions with clear regulations, and upgrade Chainalysis compliance functions.

3. Smart contract security:

- Problem: Solana's historical network outage (2022) and potential contract vulnerabilities pose risks.

- Solution: Regular audits with top companies such as Certik or Quantstamp, leveraging Solana’s stability improvements, and deploying multi-signature wallets to protect critical operations.

4. Institutional Scalability:

- Problem: Institutional pools need robust infrastructure to handle large-scale transactions.

- Solution: Optimize Solana’s parallel processing capabilities and explore Layer 2 solutions such as SOON (Solana Optimistic Network).

🟤Summary and Contribution to the Crypto Industry

Huma Finance’s technical architecture sets a benchmark for PayFi, combining Solana’s speed, stablecoin stability, and compliance to reshape traditional finance. Its modular stack sets the standard for future applications and attracts developer innovation. By addressing off-chain transparency and regulatory risks, Huma can consolidate its leadership in RWA and DeFi. The project’s high returns and realistic cash flows drive adoption, and its open architecture promotes ecological expansion. Huma’s success may promote the widespread application of the Web3-Web2 hybrid model and form a closed-loop financial ecosystem.
