Protocol Overview

Fountfi is a protocol for tokenizing Real World Assets (RWA) on-chain, providing a secure and compliant framework for bringing traditional finance assets into DeFi.

Fountfi Enables:

• Tokenization of RWAs with flexible strategy implementations

• Share-based accounting for RWA representation using ERC4626 vaults

• NAV (Net Asset Value) oracle integration via Reporter contracts

• Built-in KYC/AML compliance features with extensible hook system

• Two-phase gated deposit flow for compliance verification

• Advanced withdrawal management for illiquid assets

• Role-based access control for protocol administration

Protocol Architecture

Key Terms and Concepts

• tRWA (Tokenized Real World Asset): An ERC4626-compatible token that represents ownership shares in an underlying real-world asset strategy.

• Strategy: A contract that manages underlying assets and deploys its own tRWA token. Strategies implement different investment approaches for the underlying assets.

• Registry: The central hub of the protocol that manages all component registrations and deployments, ensuring only authorized components can interact.

• Conduit: A security contract that manages all asset transfers between users and the protocol, providing a layer of protection for token movements.

• Hook: A pluggable validation component that enforces rules before token operations (deposits, withdrawals, transfers). Hooks enable extensible compliance mechanisms.

• Rules Engine: A special type of hook that coordinates multiple sub-hooks, allowing complex validation logic to be composed from simpler rules.

• Reporter: An oracle contract that provides asset valuations to the protocol, enabling accurate share pricing.

• GatedMint: A two-phase deposit mechanism where assets are held in escrow pending explicit approval, allowing for issuer control over flow of funds and timing of acceptance.

• Deposit Escrow: A contract that temporarily holds assets during the two-phase deposit process until they are either accepted or refunded.

• Withdrawal Queue: A mechanism for managing withdrawals from illiquid assets, allowing for orderly processing of redemption requests.
