RWA Collateral Valuation Update Trigger

WHAT IT DOES

The RWA Collateral Valuation Update Trigger enables you to update the on-chain valuation of tokenized real-world assets used as collateral in DeFi protocols. You specify the collateral contract address, asset ID, and the new valuation amount. The tool reads the current asset information, valuation, collateral ratio, loan-to-value (LTV) ratio, and checks if the update is allowed. It then executes the valuation update transaction, which can trigger margin calls or adjust loan parameters based on the new valuation. This provides a critical mechanism for maintaining accurate collateral values for RWA-backed loans.

HOW TO USE

Connect your EVM wallet and select your network. Enter the collateral contract address and the asset ID you want to update. Specify the new valuation (in USD with 8 decimals). Click "Preview update" to see the current valuation, asset details, collateral ratio, LTV ratio, and the impact of the change. If everything looks correct, click "Trigger valuation update" to execute the update. Progress is shown in real-time, and gas costs are calculated accurately using effectiveGasPrice.

ONE TECHNICAL SECTION — THE REAL MECHANISM

The tool interacts with a collateral valuation contract that manages RWA collateral values. The getAssetInfo() function returns the asset's name, symbol, current valuation, and last update timestamp. The getCollateralRatio() and getLTV() return the current collateralization and loan-to-value ratios, which are critical for determining loan health. The isValuationUpdatable() function checks if the update is allowed based on governance rules, time locks, or other constraints. The updateValuation() function sets the new valuation on-chain, which then triggers any necessary rebalancing of loan positions. If the valuation decreases, it may trigger margin calls for borrowers; if it increases, it may allow additional borrowing. This ensures that RWA collateral values remain accurate and loans stay properly collateralized.

WHAT IT CANNOT SEE

The tool cannot verify off-chain valuation accuracy or guarantee oracle data correctness. It does not validate that the new valuation is based on reliable market data, that the appraisal method is sound, or that the asset's actual value matches the on-chain record. It cannot detect if the valuation is being manipulated or if the oracle data is compromised. It does not provide financial advice or ensure that the update is appropriate. The tool also cannot recover from a valuation update that triggers unintended liquidations — ensure the valuation is accurate before updating.

PLEASE NOTE

This tool is EVM-only and supports Ethereum, Goerli, Sepolia, Optimism, Arbitrum, Polygon, and Base. It does not support Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. Valuation updates should be based on reliable, audited data sources. Incorrect valuations can lead to improper loan liquidations or under-collateralization. The tool is provided free and as-is; users assume full responsibility for their valuation decisions.
