Main Vault Contract Functions

deposit(uint256 amount, uint8 lockDays)

• Parameters: amount (in wei, 18 decimals), lockDays (1,5,10,20)

• Requires: USDT approved

• Emits: event Deposited(address user, uint256 amount, uint8 lockDays)

withdraw(uint256 positionId)

• Parameters: positionId (position ID)

• Requires: matured position (unlock date passed)

• Returns: principal + yields in USDT

• Emits: event Withdrawn(address user, uint256 positionId, uint256 amount)

getUserPositions(address user)

• View function

• Returns: array of Position structs (amount, lockDays, startTime, endTime, rewards)

getPendingRewards(uint256 positionId)

• View function

• Returns: uint256 pending rewards in USDT

calculateYield(uint256 amount, uint8 lockDays)

• View function

• Returns: projected total yield (based on tier fixed rate)

Strategy Manager Functions (example)

getAllocationPercentages() → Returns struct with % for lending, trading, reserve getBotPerformance() → Returns success rate, total ops, etc.

Integration Recommendations

• Use ethers.js or web3.js for calls

• Always verify chainId == 56

• Implement error handling for revert messages

• Monitor events (Deposited, Withdrawn, etc.) via websocket provider

• Use multicall to optimize queries (if available)

Simple deposit example (ethers.js):

const vault = new ethers.Contract(VAULT_ADDRESS, VAULT_ABI, signer);
const tx = await vault.deposit(ethers.utils.parseUnits("100", 18), 10); // 100 USDT, 10 days
await tx.wait();
console.log("Deposit successful!");
