From PIX to DeFi Yield
in Four Steps

EFIX bridges the gap between Brazil's regulated financial infrastructure and permissionless DeFi lending markets.

Step 01
💳
Deposit via PIX
Send BRL via PIX to the EFIX SPE. Funds are received instantly through HausBank's payment infrastructure.
Step 02
🏦
Buy DI Fund Shares
The SPE purchases DI-linked fund shares through Genial IAAS, tracking the CDI interbank rate (~15% p.a.).
Step 03
🪙
Mint efixDI Tokens
efixDI tokens are minted 1:1 on Polygon, representing the underlying fund shares. Tokens accrue daily CDI yield.
Step 04
Leverage on Morpho
Bridge efixDI to Base via LayerZero, deposit as collateral on Morpho Blue, borrow USDC, and loop for enhanced yield.

Why Tokenized DI Funds?

The protocol's core innovation: leveraging D+0 redemption of Brazilian DI funds to eliminate FX hedge costs while maintaining capital protection.

🛡️
Regulated Collateral
efixDI is backed 1:1 by ANBIMA-certified DI fund shares held at a CVM-registered securitizer. Unlike crypto-native collateral, the underlying asset has guaranteed capital protection and daily yield accrual.
⏱️
D+0 Same-Day Redemption
DI funds offer same-day liquidity (D+0), enabling instant collateral liquidation. This eliminates the need for expensive FX derivatives that cost 2-3% annually in traditional RWA strategies.
🌐
Cross-Chain Architecture
Built on Polygon (minting & yield) and Base (DeFi leverage) with LayerZero V2 OFT bridging. Composable with the broader DeFi ecosystem — Morpho Blue, Aave, and beyond.
📊
Sustainable Yield Spread
The protocol earns the spread between CDI returns (~15% APY) and USDC borrow costs (~1-5% APY). This is a structural, non-speculative yield source independent of crypto market conditions.

Yield Enhancement Model

Each leverage loop multiplies exposure to the CDI-USDC spread. The protocol targets conservative 2-3 loops for optimal risk-adjusted returns.

Strategy Multiplier Gross APY Net APY Health Factor
Hold (no leverage) 1.00× 15.0% 12.5%
1 Loop 1.77× 22.7% 20.0% 1.77
2 Loops ★ Recommended 2.36× 28.6% 25.6% 1.49
3 Loops 2.82× 33.2% 29.8% 1.38
4 Loops (max) 3.05× 35.5% 33.0% 1.28

* Net APY after 20% performance fee. Morpho Blue LLTV: 77%. Auto-deleverage triggers at Health Factor < 1.15. CDI rate: ~14.9% (Feb 2026). USDC borrow rate varies with market utilization.

Whitepaper

A comprehensive technical document covering the protocol's architecture, yield mechanics, risk framework, smart contract design, and regulatory compliance structure.

The whitepaper details how EFIX creates a sustainable yield spread by bridging Brazil's R$6+ trillion fixed-income market into permissionless DeFi lending protocols. It covers the mathematical model behind recursive leverage loops, liquidation risk analysis, oracle design, and the regulatory framework under CVM Resolution 60.
