Why Chain-Fi?
A Trust-First Gateway to Secure Web3 Integration
Chain-Fi is a compliance-anchored, zero-vault-tolerance platform that serves as a trust-first Web3 gateway for businesses and users alike. We provide a secure bridge between enterprises and end-users, enabling both to interact in a vetted, transparent crypto ecosystem.
What is Chain-Fi?
Chain-Fi combines institutional-grade security with user-centric design to ensure every interaction – from payments to data sharing – is trustworthy and verifiable. Our architecture supports flexible asset management tailored to user needs: whether you require stable-value transactions via stablecoin payment rails for predictable payments, or traditional crypto asset management for trading, DeFi, and other Web3 activities. All while preserving custodial independence (users retain control of their keys and assets).
This means companies can confidently integrate blockchain into their operations without ceding control of funds, and users can participate in Web3 services without trusting any centralized vault or intermediary. The result is a unified gateway where compliance requirements are built-in and every actor and action is authenticated by design.
Built on Base: Base is Chain-Fi's home chain and foundational layer. While Chain-Fi's identity and OAuth systems are architectural features that work across all supported chains, Base serves as the primary ecosystem layer where token launches, governance mechanisms, and ecosystem-specific features are anchored. We chose Base for its exceptional combination of low transaction costs, high scalability, EVM compatibility, and strong alignment with compliance-focused infrastructure. Base's commitment to security, decentralization, and regulatory clarity makes it the ideal foundation for Chain-Fi's trust-first architecture. Chain-Fi supports multi-chain operations across Base, Arbitrum, Optimism, Polygon, and Ethereum, with vaults and payment rails deployed natively on each chain, while Base remains the home for ecosystem-level features and token economics.
No direct wallet connections: Unlike traditional Web3, users never need to connect their wallets directly to dApps or give wallet approvals to unknown applications. All interactions go through Chain-Fi's secure module, shielding users from malicious dApp connections and eliminating the need for repeated wallet approvals.
OAuth-style authorization with mutual consent: Chain-Fi uses an OAuth-style authorization model where each connected dApp can determine the scope of approval, but all interactions require explicit user consent. This creates a "negotiation of trust" - mutual consent that is revocable by design. Clients can only enforce minimal compliance data requirements, and users approve and select which payment type they want to use for each client, sharing only what is minimally needed.
Gasless vault interactions: Unlike traditional wallets that require users to pay gas fees for every transaction, Chain-Fi vault interactions are completely gasless. The guardian network covers transaction fees, making Web3 interactions as seamless as traditional web applications while maintaining full self-custody of assets.

The Problem Chain-Fi Solves
Today's crypto onboarding and integration landscape is fragmented and fraught with trust issues. Users and enterprises face a "Wild West" environment with siloed identity checks and inconsistent security practices.
Onboarding Friction
Every project requires its own wallet connection and identity process, leading to repetitive KYC and a poor user experience. This not only frustrates users but also deters non-crypto-savvy customers from onboarding.
Trust vs. Decentralization Trade-offs
Organizations are wary of operating in a "trustless" ecosystem. Regulations demand auditability and oversight, yet blockchain transactions across disparate wallets are hard to reconcile and monitor.
Security Gaps
Users are expected to be their own security experts – managing private keys, avoiding phishing scams, and deciphering transaction data. Mistakes or malicious actors can lead to catastrophic losses, which the industry has come to accept as "inevitable."
Bridging Users and Enterprises in Both Directions
Chain-Fi acts as a two-way bridge that simultaneously serves the needs of end-users and enterprises, creating a symbiotic ecosystem.
The Chain-Fi Bridge: Our benefits remain constant across all integrations, with users playing a central role in every interaction. Whether it's DeFi lending, NFT marketplaces, payment processing, gaming platforms, or e-commerce, Chain-Fi provides the same foundational benefits: gasless transactions, multi-sig security, OAuth authentication, and KYC compliance.
Users never need to connect wallets directly to projects or pay gas fees. Enterprises get immediate access to a vetted, compliant user base without building infrastructure from scratch. This creates a win-win ecosystem where users enjoy seamless Web3 experiences while enterprises focus on their core product.

Enhancing UX and Business Usability in Crypto
Predictable Stablecoin Payments
By leveraging stablecoin rails for transactions, Chain-Fi ensures payments are fast and stable in value. Users and merchants can transact in currencies like USDC/USDT that don't fluctuate, making crypto payments viable for commerce.
Full Connectivity Across Ecosystems
Chain-Fi offers full-stack connectivity to the crypto ecosystem. It supports multiple blockchains (Ethereum, Base, Arbitrum, Optimism, Polygon) and integrates with existing Web2 systems, creating a unified environment.
Audit-Ready Compliance and Monitoring
Every transaction and session is logged and auditable by design. The system automatically enforces KYC/AML checks, monitors transactions in real time for suspicious activity, and maintains detailed logs for regulatory reporting.
Secure Sessions and Access Control
User sessions in Chain-Fi are protected by strong multi-factor security and fine-grained access controls. The dual-device approach ensures that even if one device is compromised, an attacker cannot hijack the session.
No Direct Wallet Connections
Users never need to connect their wallets directly to dApps or give wallet approvals to unknown applications. All interactions go through Chain-Fi's secure gateway, eliminating phishing risks and the need for repeated wallet approvals.
OAuth-Style Consent & Minimal Data Sharing
Each dApp can request specific scopes, but you maintain full control. Approve only what's needed, select your preferred payment method per client, and share minimal compliance data. All consents are revocable by design - true negotiation of trust with mutual consent.
Gasless Vault Interactions
Unlike traditional wallets that require gas fees for every transaction, Chain-Fi vault interactions are completely gasless. The guardian network covers all transaction fees, making Web3 as seamless as traditional web applications while maintaining full self-custody.
The Trust Stack: Technical Architecture
Chain-Fi's Trust Stack is a comprehensive, multi-layered security architecture that enforces trust, security, and compliance at every level of the system. Each layer is independently verifiable and works together to create a robust, transparent, and secure ecosystem.
Consent (Multi-Signature)
All critical operations require explicit user consent through multi-signature authentication. Every transaction, data sharing request, and access grant must be approved by both the owner wallet and the auth wallet (2FA device). This dual-signature requirement ensures that no action can be taken without the user's explicit approval on two separate devices, preventing unauthorized access even if one device is compromised.
Asset Protection
Assets are protected through non-custodial vault architecture with multi-signature enforcement at the smart contract level. The ChainFiVault smart contract requires both owner and auth signatures for any asset movement, and includes emergency withdrawal mechanisms, whitelisting controls, and gasless transaction execution. Assets remain in full user custody at all times, with no intermediary control or access.
Enclosed Ecosystem
Chain-Fi operates as an enclosed ecosystem where all participants (users and applications) are vetted and verified before access. Applications must register and be approved in the Chain-Fi network registry. Users undergo KYC/AML verification. Wallets never connect directly to dApps - all interactions go through Chain-Fi's secure gateway, creating a walled garden of trusted actors where unknown or malicious entities cannot gain access.
Transparency and Auditability
Every session, transaction, and interaction is logged with immutable audit trails. All actions are tied to verified identities, device attestations, and cryptographic proofs. Users and enterprises can access complete audit logs filtered by session, device, wallet, app, function, and time window. This transparency enables regulatory compliance, dispute resolution, and security auditing without exposing sensitive personal data.
Guardian Attestation (Internal Stack)
Chain-Fi's internal Guardian system provides cryptographic attestation for all user actions. When a user performs a sensitive operation via the mobile app, Chain-Fi uses the application's Guardian private key to co-sign the response. The web app receives both the raw response and the Guardian-signed copy, enabling verification of authenticity. This internal attestation layer ensures that all actions are verified by Chain-Fi's secure process and cannot be tampered with in transit.
Multi-Guardian Network (Coming Soon)
Enterprise clients will be able to add project-specific attestation layers within their enterprise accounts and workflows. This allows organizations to implement custom guardian networks that align with their internal security policies, compliance requirements, and operational workflows. Each enterprise can configure multiple guardian nodes with different roles and permissions.
