Principal-Protected Vault Depositor

WHAT IT DOES

This tool enables DeFi users to deposit funds into principal-protected vaults. Principal-protected vaults are designed to safeguard the initial deposit amount (principal) while generating yield from various strategies. Users can configure the protection level (0-100%), which determines how much of the principal is guaranteed. Higher protection typically results in lower yields, while lower protection allows for higher potential returns. It connects to your wallet and reads the vault contract address, deposit amount, principal protection level, yield rate, lock period, deposit status, deposit history, and timestamps. The tool signs and submits transactions to deposit into principal-protected vaults, set protection levels, update deposit status, record deposit metadata, and emit deposit events.

HOW TO USE

1. Connect your wallet using the wallet bridge (supports MetaMask, WalletConnect, and other EVM-compatible wallets).

2. Select the target network that matches your vault contract deployment.

3. Enter the vault contract address and click "load contract" to initialize the connection.

4. Click "fetch vault status" to retrieve the current yield rate, lock period, deposit status, and deposit history.

5. Review the yield rate and lock period — these determine the returns and the duration of your deposit.

6. Enter the deposit amount (in native token) and the principal protection level (0-100%).

7. Click "validate deposit" to verify that the deposit amount and protection level are valid.

8. Click "check deposit history" to view your past deposits.

9. Review the deposit amount, protection level, yield rate, and lock period before executing.

10. Click "deposit" to sign and submit the transaction that deposits your funds into the principal-protected vault.

TECHNICAL MECHANISM

The tool uses ethers.js v5.7.2 to interact with any EVM-compatible principal-protected vault contract that implements a standard interface (getYieldRate() view returns (uint256), getLockPeriod() view returns (uint256), getDepositStatus(address) view returns (uint8), deposit(uint256, uint256) external payable, getDepositHistory(address) view). The deposit function accepts the deposit amount and the protection level as parameters. The contract calculates the yield rate based on the protection level — higher protection yields lower returns. The lock period determines how long the funds are locked in the vault. The contract validates that the protection level is within the allowed range and that the deposit meets the minimum requirements. The getDepositStatus view returns the current status of the user's deposit (none, active, locked, withdrawn). The contract maintains a history of deposits, storing timestamps, amounts, and protection levels for audit purposes. Transaction handling follows EIP-1559 gas price calculations using receipt.effectiveGasPrice for accurate cost reporting. Deposit metadata is recorded both in the contract's history and locally for the user's reference.

WHAT IT CANNOT SEE

This tool operates purely on-chain and cannot verify off-chain yield accuracy — it does not check whether the yield rate is accurate or generated from reliable strategies. It cannot validate the protection mechanism — the tool cannot confirm that the vault's protection mechanism is correctly implemented or that it will actually protect the principal. It cannot detect vault risks — the tool cannot identify vulnerabilities in the vault's strategy, smart contract risks, or external dependencies. It cannot ensure principal protection — the tool relies on the contract's implementation and does not independently verify that the principal is fully protected. The tool also cannot guarantee that principal is fully protected — while the vault is designed to protect principal, there is no guarantee of full protection under all circumstances.

PLEASE NOTE

This tool works exclusively with EVM-compatible blockchain networks (Ethereum, Polygon, Arbitrum, Optimism, Base, etc.). It requires the vault contract to implement the interface described above. All transactions incur gas fees paid by the connected wallet. The tool maintains no persistent storage — all state is refreshed from the blockchain on each session. Principal-protected vaults are designed to reduce risk, but they do not eliminate all risks. Understanding the trade-off between protection and yield is important — higher protection means lower potential returns, and vice versa. Always review the vault's strategy, lock period, and fee structure before depositing. Consider your risk tolerance and investment goals when choosing the protection level.
