Eagle OVault

Omnichain Yield Aggregator - ERC-4626 compliant vault + LayerZero V2 share bridging

📋 Table of Contents

Overview

Eagle OVault is an ERC-4626 compliant, WLFI-denominated vault with synchronous deposits and redemptions (deposit/mint/withdraw/redeem). Internally, the system can hold WLFI and other exposures (e.g. USD1) and accounts for them in WLFI-equivalent terms via totalAssets(). Vault share exposure can be bridged across chains via LayerZero V2.

Key Features

🏦 ERC-4626 (synchronous): Standard deposit/mint/withdraw/redeem interface; user deposits are WLFI (the ERC-4626 asset())
🌐 Omnichain Native: LayerZero V2 enables cross-chain bridging of vault shares
📈 Strategy support: Optional strategy layer can deploy capital into external positions (e.g. Charm / Uniswap V3)
🔒 Non-Custodial: Your keys, your tokens - full control maintained
⚡ Gas Optimized: Efficient smart contracts with comprehensive testing
🛡️ Security-focused: Built to be auditable; arrange an independent review before production use

Multi-Chain Support

Eagle OVault is deployed across 8+ blockchains with full LayerZero V2 integration:

Strategy Contracts

Strategy contracts live under contracts/strategies/ and integrate with external venues (e.g. Charm / Uniswap V3). Exact strategy wiring is deployment-specific—use deployments/ and frontend/src/config/contracts.ts as the source of truth.

Cross-Chain Contracts

Asset	Base Contract	Spoke Contracts

Solana Integration

Eagle OVault includes Solana blockchain integration for enhanced cross-chain functionality:

Solana Programs

Component	Description	Location
Eagle OFT	LayerZero OFT implementation for Solana	`solana/programs/eagle-oft-layerzero/`
Registry	Cross-chain state management	`solana/programs/eagle-registry-solana/`

LayerZero Integration

# Build Solana programs
cd solana/programs
anchor build

# Run LayerZero examples
cd solana/layerzero
pnpm install
npx tsx examples/send-to-ethereum.ts

Solana Addresses

OFT Program ID: Deployed program address (see deployment logs)

Testing & Security

Testing

# Run the test suite
pnpm test

# Run security analysis (when dependencies are available)
# Note: Advanced testing requires additional setup

Security Features

✅ Access Controls: Multi-signature recommended for admin functions
✅ OpenZeppelin Standards: Uses standard, battle-tested primitives where applicable
✅ Defense-in-depth: Reentrancy guards, input checks, and conservative external integrations

Security Monitoring

Dependabot: Automated dependency updates and security alerts
Manual Reviews: Regular security assessments
Audit Reports: If/when published, link them here (recommended before production use)

Usage

Deposit & Withdraw

// ERC-4626 deposit (WLFI asset)
IERC4626 vault = IERC4626(EAGLE_OVAULT);
IERC20 asset = IERC20(vault.asset());

asset.approve(address(vault), assets);
uint256 shares = vault.deposit(assets, receiver);

// ERC-4626 redeem (synchronous)
uint256 assetsOut = vault.redeem(shares, receiver, owner);

Cross-Chain Bridging

// See `frontend/abis/EagleShareOFT.json` for the exact structs.
// High-level flow:
// 1) quoteSend(sendParam, payInLzToken)
// 2) send(sendParam, fee, refundAddress)

Development

Smart Contracts

# Install dependencies
pnpm install

# Run tests
pnpm test

# For contract development, additional tools may be needed:
# - Foundry (forge) for advanced Solidity testing
# - Hardhat for Ethereum development
# - LayerZero CLI for cross-chain configuration

Frontend Integration

The frontend/ directory contains integration examples and hooks:

cd frontend

# Install dependencies
pnpm install

# Start development server (view integration examples)
pnpm dev

# Build examples
pnpm build

Solana Development

cd solana/programs

# Build Solana programs (requires Anchor)
anchor build

# Deploy to devnet (requires Solana CLI)
anchor deploy --provider.cluster devnet
