Depeg Swap Settlement Tool

WHAT IT DOES

This tool evaluates settlement readiness for DeFi swaps with integrated depeg detection, helping users determine if they can successfully settle a swap before initiating a transaction. Given a settlement contract address, token in and token out addresses, and an amount, it reads the user's token balance and allowance for the settlement contract, checks if the balance and allowance are sufficient, and calls the settlement contract's canSettle() function to verify all on-chain conditions are met. It also retrieves the settlement output amount using getSettlementAmount() if available. The tool then provides a clear settlement readiness status—Ready to settle, Pending, or Blocked—along with a detailed breakdown of each readiness factor. Additionally, it integrates depeg detection by calling the settlement contract's getDepegStatus() function or, if not available, reading from a provided oracle address. The depeg status is displayed as Critical, Warning, or Stable, with the deviation percentage shown. All data is pulled directly from the blockchain and oracle in real time, providing a transparent, informed view before any settlement transaction is attempted.

HOW TO USE

Connect your wallet using the Connect button in the header. Select the target network from the dropdown—Ethereum Mainnet, Polygon, Optimism, Arbitrum One, Base, or Sepolia testnet. Enter the settlement contract address (the contract that executes swaps or settlements), the token in address, and the token out address. Enter the amount to settle in human-readable format. Optionally, provide an oracle or price feed address for depeg detection if the settlement contract does not expose getDepegStatus. Click "Check settlement." The tool will fetch your token balance, allowance, the settlement output amount, and call the contract's canSettle function. It will also check depeg status from the contract or oracle. Results appear in the card below with a prominent settlement readiness badge, depeg status indicator, detailed breakdown of readiness factors (balance sufficient, allowance sufficient, depeg acceptable, canSettle returns true), and all relevant addresses with block explorer links. Use this information to decide whether to proceed with the settlement transaction.

INTEGRATED DEPEG DETECTION WITH SETTLEMENT READINESS

The tool provides two layers of depeg detection. First, it attempts to call the settlement contract's getDepegStatus() function, which returns a status code (0 = safe, 1 = warning, 2 = critical) and a deviation percentage. This is the most reliable source as it reflects the contract's own view of depeg conditions. If the contract does not implement this function, the tool falls back to reading from a provided oracle address. It calls latestRoundData() or latestAnswer() to fetch the current price, compares it against the expected peg (1.0 for stablecoins), and calculates the deviation percentage. The tool then displays the depeg status with color-coded indicators and includes the deviation percentage. Settlement readiness is determined by combining four factors: sufficient token balance, sufficient allowance for the settlement contract, acceptable depeg status (not critical), and the contract's canSettle() function returning true. Each factor is displayed with a checkmark or cross, making it easy to identify why a settlement might be blocked and what action is needed.

WHAT IT CANNOT SEE

This tool cannot guarantee settlement execution—on-chain conditions may change between the check and the transaction. It cannot verify off-chain settlement conditions or ensure that the settlement contract is correctly configured for the specific swap. It cannot ensure counterparty solvency or detect settlement fraud. It cannot validate the authenticity of settlement terms or assure that the settlement contract is free from vulnerabilities, bugs, or malicious code. It cannot predict future depeg events or guarantee that the depeg status will remain stable during settlement. It cannot verify that the oracle price feed is accurate or protected from manipulation. It cannot detect stale oracle data or ensure that the oracle is operating correctly. It cannot provide financial advice or guarantee that a settlement is profitable or safe. All data is provided as-is for informational purposes only; any reliance on the tool's output for settlement decisions is the sole responsibility of the user.

PLEASE NOTE

This tool supports EVM-compatible chains only: Ethereum Mainnet (1), Polygon (137), Optimism (10), Arbitrum One (42161), Base (8453), and Sepolia testnet (11155111). Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, and XRP are not supported. The tool requires a Web3 provider (MetaMask or WalletConnect) and access to an RPC endpoint for the selected chain. It does not store any wallet data, token addresses, or settlement records. All queries are performed directly against the blockchain in real time. The tool does not execute settlements—it only provides read-only information. Depeg detection is a heuristic based on contract state or oracle price feeds and does not guarantee that a depeg has occurred or that settlement conditions are safe. Always verify critical data independently through a block explorer and consult with financial advisors before making any settlement decisions.
