What we built

OPN Pulse is a real-time yield optimizer built for OPN Chain.

It is an ERC-4626 vault that automatically splits user deposits across two yield strategies. Yield accrues on-chain every second, and anyone can trigger harvesting and rebalancing at any time.

Why OPN Chain

Frequent harvesting is the main feature of this product.

On most chains this is too expensive because of gas and slow blocks. OPN Chain’s ~1 second finality and very low predictable fees make frequent compounding practical and profitable.

The whole system is designed around this advantage. Without OPN’s performance, the core value would disappear.

Key Features

• On-chain per-second yield accrual
• Permissionless harvest and rebalance with keeper incentives
• Live dashboard showing TVL, total harvests, and exact seconds since last harvest
• One-click deposit and capital deployment

Technical Highlights

The main function anyone can call:

function harvestAndRebalance() external;

Strategies are registered with their allocation weights at deployment:

vault.addStrategy(lendingStrategy, 6000); // 60%
vault.addStrategy(dexStrategy, 4000);     // 40%

Every strategy must follow this interface:

interface IStrategy { 
function deposit(uint256 amount) external;
    function withdraw(uint256 amount) external;
    function harvest() external returns (uint256 profit);
    function totalAssets() external view returns (uint256);
}

All logic lives on-chain. The design depends on OPN’s fast blocks and low fees to make repeated calls cheap.

On-Chain Verification

The following contracts were deployed by this wallet inside the Season 1 window:

PulseVault:        0x41a4640745cFeF401FCAfED8269CcEA8Bd71def3
LendingStrategy:   0x928c5716a7D54a4bf6006666f6A4e86BcAB45cfe
DexStrategy:       0x82Ae3f146e8825bd5C5233a6bCF4a9adD2266352

Dozens of deposits and on-chain harvests/rebalances have already been executed with the same wallet to prove real usage and activity.
