From PIX to DeFi Yield
in Four Steps

Bridging Brazil's regulated financial infrastructure into permissionless DeFi lending markets.

Step 01
💳
Deposit via PIX
Send BRL via PIX to the EFIX SPE. Funds 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 minted 1:1 on Polygon, representing 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, loop for enhanced yield.
Advantages

Why Tokenized DI Funds?

D+0 redemption eliminates FX hedge costs while maintaining capital protection.

🛡️
Regulated Collateral
Backed 1:1 by ANBIMA-certified DI fund shares held at a CVM-registered securitizer. Guaranteed capital protection with daily yield accrual.
⏱️
D+0 Same-Day Redemption
Same-day liquidity enables instant collateral liquidation. Eliminates the need for expensive FX derivatives that cost 2-3% annually.
🌐
Cross-Chain Architecture
Built on Polygon (minting & yield) and Base (DeFi leverage) with LayerZero V2 OFT bridging. Composable with Morpho, Aave, and beyond.
📊
Sustainable Yield Spread
Earns the spread between CDI returns (~15%) and USDC borrow costs (~1-5%). Structural, non-speculative yield independent of crypto markets.
Economics

Yield Enhancement Model

Each leverage loop multiplies exposure to the CDI-USDC spread. Protocol targets 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.
