Options Vault Collateral Recycling Tool

WHAT IT DOES

Options Vault Collateral Recycling Tool is a DeFi tool that optimizes collateral utilization in options vaults by recycling excess collateral into new positions. It reads the user's wallet address, options vault contract address, current option position details (collateral amount, strike price, option type, expiry), collateral token address and balance, current collateral utilization, vault health metrics (collateral ratio, risk parameters), account nonce, gas estimates for recycling steps, previous recycling records, and market conditions (implied volatility, underlying price). The tool then executes a multi-step recycling process: withdrawing excess collateral from the options vault, reallocating collateral to new option positions, rolling existing option positions, adjusting collateral ratios to maintain optimal health, claiming any expired option proceeds, and transferring reclaimed collateral to the user or a new vault.

HOW TO USE

Connect your wallet via the built-in connector. Select the network where the options vault is deployed. Enter the options vault contract address, the collateral token address, and the new option position details (strike price, option type, expiry). The tool will read on-chain data and display a preview including: vault address, collateral token, current collateral amount, collateral utilization percentage, vault health ratio, new position details, excess collateral available, underlying price, implied volatility, estimated gas, and the recycling steps. Review all details carefully. Click "recycle collateral" to execute the recycling process. The tool will guide you through five steps: withdrawing excess collateral, rolling positions, adjusting ratios, claiming proceeds, and transferring reclaimed collateral.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with options vault contracts. It reads the current position details using `getPosition(address)` which returns collateral amount, strike price, option type, and expiry. Collateral utilization is read via `getUtilization()` and vault health via `getHealthRatio()`. Market conditions are read from oracles: underlying price using `getUnderlyingPrice()`, and implied volatility using `getImpliedVolatility()`. Excess collateral is calculated as (collateral balance - required collateral) based on the vault's risk parameters. The recycling process calls `withdrawExcessCollateral()`, `rollOptions()`, `adjustCollateralRatio()`, and `claimExpiredOptions()` on the vault contract. Gas estimates are calculated using `estimateGas` on each method with EIP-1559 fee data from `feeData`, and the total gas cost is summed. The tool uses `effectiveGasPrice` from receipts for accurate cost accounting. Previous recycling records are scanned using `eth_getLogs` for `CollateralRecycled` events, with adaptive chunking (halving chunk size on failure) to handle different RPC limits. All transactions are built with EIP-1559 fee data, and the tool ensures sequential execution of all steps.

WHAT IT CANNOT SEE

This tool cannot predict future option price movements that affect collateral requirements. It cannot guarantee that new option positions are profitable—options trading involves significant risk. It cannot detect if volatility spikes trigger margin calls after the recycling is complete. It cannot ensure that collateral is not locked in expired options that cannot be claimed. It cannot verify that option pricing models used by the vault are accurate. It cannot prevent front-running of recycling transactions by other market participants. It cannot validate that vault risk parameters are up to date with current market conditions. It cannot predict changes in underlying asset prices that could affect collateral requirements.

PLEASE NOTE

This tool is EVM-only and supports Ethereum, Polygon, BNB Chain, Arbitrum, Optimism, and Avalanche. All transactions are signed by the connected wallet, and the user pays gas fees for each step. Options trading involves significant risk—only recycle collateral if you understand the risks. The tool does not provide financial advice. Always verify the proposed recycling strategy before signing. Test on testnet before using on mainnet. The tool does not store or transmit any vault or position data.
