RWALayer Dual Yield Overview

RWALayer offers a dual yield system for assets bridged from Ethereum, allowing users and smart contracts to earn yields through auto-rebasing and real-world assets (RWA).

​
Yield Generation

Bridged assets on RWALayer generate yield through:
  1. Auto Rebasing: Yield from L1 ETH native staking via Lido, T-bill yield from MakerDAO, and native staking of BNB & CAKE.
  2. Real World Assets (RWA): Yield from RWALayer ecosystem protocols covering property, commodities, private credit, and future developments.
Key features include:
  • Auto Rebasing Yield: Credited on-chain every 7 days.
  • XUSD Stablecoin: After bridging USDT, users receive XUSD which auto-rebases yield from MakerDAO’s Treasury Bill protocol. XUSD can be redeemed for DAI when bridging back.
  • Monitoring: Track dual yield progress via the RWALayer App.

​
Yield Modes for Smart Contracts

Smart contract accounts on RWALayer can choose from three yield modes:
  1. Void (DEFAULT): No yield; ETH balance remains constant.
  2. Automatic: ETH balance increases automatically.
  3. Claimable: Yield accumulates separately and can be claimed.

​
Configuring Yield Modes

To change yield modes, smart contracts must interact with the RWALayer yield contract.

​
Yield Mode Details

​
Void Yield (DEFAULT)

Ensures compatibility with existing Ethereum Mainnet and other EVM-compatible dapps, requiring no modifications.

​
Automatic Yield

Depositing 1 ETH results in an increase to approximately 1.04 ETH after a year. Suitable for dapps that want to pass yield benefits directly to users. 
interface IRWALayer {
    // Interface methods
}

contract MyContract {
    constructor() {
        IRWALayer(<yieldContractAddress>).configureAutomaticYield(); // Enables automatic yield
    }
}

​
Claimable Yield

ETH balance remains unchanged, but yield accumulates separately and can be claimed. 
interface IRWALayer {
    // Interface methods
}

contract MyContract {
    constructor() {
        IRWALayer(<yieldContractAddress>).configureClaimableYield();
    }

    function claimYield(address recipient, uint256 amount) external {
        IRWALayer(<yieldContractAddress>).claimYield(address(this), recipient, amount);
    }

    function claimAllYield(address recipient) external {
        IRWALayer(<yieldContractAddress>).claimAllYield(address(this), recipient);
    }
}

​
Managing Governors

The governor is responsible for claiming a contract’s yield and gas. Initially, the contract’s address is the governor but can be updated. 
interface IRWALayer {
    // Interface methods
}

contract MyContract {
    constructor(address gov) {
        IRWALayer(<yieldContractAddress>).configureClaimableYield();
        IRWALayer(<yieldContractAddress>).configureGovernor(gov); // Sets the governor address
    }
}

​
Claiming Yield and Gas

Efficient management of yield and gas claims maximizes earnings and resource management.

​
Claiming Yield

Yield in Claimable mode can be claimed manually: 
function claimYield(address recipient, uint256 amount) external {
    IRWALayer(<yieldContractAddress>).claimYield(address(this), recipient, amount);
}

function claimAllYield(address recipient) external {
    IRWALayer(<yieldContractAddress>).claimAllYield(address(this), recipient);
}

​
Claiming Gas

Configure and claim gas for managing operational costs, similar to claiming yield.

​
Monitoring Yield

Users can monitor their yield progress via the RWALayer App, ensuring they have up-to-date information on their earnings. By following these configurations and guidelines, you can effectively manage yield and gas for your smart contracts on RWALayer, leveraging the dual yield system to maximize your returns.
