Collateral Top-Up Executor

WHAT IT DOES

Collateral Top-Up Executor is a DeFi tool that lets you deposit additional collateral into an existing lending position to improve your health factor and reduce liquidation risk. It reads your current debt, collateral balance, health factor, and borrowing power, then simulates the impact of adding more collateral. This helps you understand exactly how much your position will improve before you commit. The tool handles the collateral approval and deposit in a single transaction, making it easy to strengthen your position when markets are volatile or when you want to unlock additional borrowing capacity.

HOW TO USE

Connect your EVM wallet via the BGWallet bridge. Enter your lending pool address, collateral token, and debt token. Specify the amount of collateral you want to add. Optionally, set a target health factor — if you leave it blank, the tool will show you the resulting health factor from your specified top-up amount. Click "Simulate Top-Up" to see your current health factor, debt, collateral, projected health factor after the top-up, and the additional borrowing power unlocked. Review the simulation carefully — a health factor above 1.5 is generally considered safe. Click "Execute Top-Up" to sign and broadcast the transaction. The tool handles token approval and deposit in a single transaction, providing a transaction hash for tracking.

TECHNICAL MECHANISM

The tool computes your health factor using the formula: (collateral_value * liquidation_threshold) / debt_value. It fetches token prices from the lending pool's oracle or a fallback price feed. When you execute a top-up, the tool encodes a transaction that: (1) approves the collateral token if needed, and (2) calls the pool's `deposit` function to add the collateral. If you specified a target health factor, the tool calculates the required collateral amount and suggests it to you. The entire operation is atomic — if any step fails, the transaction reverts and your position remains unchanged. The tool also calculates the additional borrowing power unlocked by the top-up, helping you understand the full benefit of the action.

WHAT IT CANNOT SEE

This tool cannot guarantee that the top-up will prevent liquidation if collateral prices drop significantly after execution. The health factor displayed is based on current prices and may be outdated by the time your transaction confirms. The tool also cannot predict oracle updates, protocol changes, or sudden market movements that could affect your position. Always monitor market conditions and consider adding a safety buffer — a health factor of 1.5 or higher is generally recommended. This tool is an aid for managing your position, not a guarantee against liquidation.

PLEASE NOTE

EVM chains only. This tool relies on the BGWallet connector and will not function on Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The user is responsible for ensuring the supplied contract addresses are correct and that the lending protocol supports the specified operations. Always double-check the simulation results and ensure you have sufficient token balance and gas before executing the transaction.
