Stablecoin Savings Rate Deposit Tool

WHAT IT DOES

Stablecoin Savings Rate Deposit Tool enables users to deposit stablecoins into protocol savings rate contracts to earn interest on their holdings. The tool reads your connected wallet address, savings contract address, stablecoin address, deposit amount, current savings rate (APY), total deposits, user deposits, accrued interest, current block timestamp, withdrawal fee, and minimum deposit. It displays the current savings rate, total deposits, your deposits, accrued interest, withdrawal fee, and minimum deposit before you deposit. Once confirmed, the tool handles token approval and executes the deposit transaction, allowing your stablecoins to earn interest.

HOW TO USE

Connect your wallet and select your network. Enter the savings rate contract address and the stablecoin address you want to deposit. Specify the deposit amount. Click "Fetch savings rate" to load the current savings details including the APY, total deposits, your deposits, accrued interest, withdrawal fee, and minimum deposit. Review all details carefully—the tool will show you the current interest rate and any fees. If everything is correct, click "Deposit" to approve token spend and execute the deposit. The tool handles the approval and deposit in one flow.

THE REAL MECHANISM — INTEREST-ACCURING DEPOSITS WITH FEE AND MINIMUM TRACKING

Unlike simple deposits that only transfer tokens, this tool implements an interest-accuring savings system with comprehensive tracking. The getSavingsInfo function returns the current savings rate (as an annual percentage yield), total deposits across all users, the user's deposit balance, accrued interest, withdrawal fee (as a percentage), and minimum deposit amount. The deposit function verifies that the deposit amount meets the minimum deposit requirement, transfers the stablecoins from the user to the savings contract, and updates the user's deposit balance. The contract accrues interest continuously based on the savings rate and the user's deposit balance. Interest can be claimed separately via claimInterest. Withdrawals may incur a fee that goes to the protocol. The tool reads all savings data via getSavingsInfo and validates the deposit amount against the minimum deposit before enabling the deposit button. All arithmetic uses ethers.js BigNumber with the token's decimal precision, and gas costs are reported using receipt.effectiveGasPrice.

WHAT IT CANNOT SEE

Cannot predict future savings rate changes—the APY can be adjusted by governance and may change over time. It cannot ensure protocol solvency—the tool has no visibility into the protocol's reserves or ability to pay interest. It cannot detect if the savings contract contains vulnerabilities—the tool does not audit the contract logic. It cannot verify off-chain interest calculations—the tool relies on the contract's interest calculation and cannot verify the formula. It cannot recover funds if the deposit is made and the protocol later fails.

PLEASE NOTE — EVM CHAINS ONLY

This tool exclusively supports EVM-compatible chains where ethers.js can connect via standard JSON-RPC. It does not support non-EVM chains such as Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The savings contract must implement the specific interface expected by this tool (getSavingsInfo, getStablecoin, deposit, withdraw, claimInterest). Always review the savings rate, fees, and minimum deposit before depositing. This tool is a savings interface, not a financial advisor or investment strategist.
