What is Chain-Fi Access Control?

Chain-Fi Access Control is an enterprise-grade smart contract security framework that protects treasury contracts and development teams with three-address protocol, team-based multi-signature, guardian attestation, and airgapped mobile 2FA.

How does the three-address protocol work?

The three-address protocol separates development, treasury, and guardian wallets for maximum security. Each transaction requires multi-signature approval from different address types, eliminating single points of failure.

Who is Chain-Fi Access Control for?

Chain-Fi is designed for DeFi projects, DAOs, blockchain startups, and enterprises requiring treasury security, team access control, and compliance automation. Ideal for projects with >$1M in assets.

Single Points of Failure

The Enterprise Digital Asset Challenge

Traditional blockchain security fails enterprises because development teams and end users work in isolated systems without unified control.

👥

Team Isolation

Developers build secure smart contracts, but teams cannot collaborate on asset management.

🏢

CFO Control

CFOs need enterprise controls, but developers work with individual wallet addresses.

📊

Compliance Gaps

Compliance requires audit trails, but blockchain transactions are scattered across multiple systems.

🔐

Single Points of Failure

Crypto wallets are isolated single-user tools without team collaboration capabilities.
