Important Notes

Token Decimals

Token	Decimals	Example
WEUSD	6	1 WEUSD = 1000000
USDC (BSC)	18	1 USDC = 1e18
USDC (Base/Arb)	6	1 USDC = 1000000
RWA Tokens	18	1 RWA = 1e18

Approval Pattern

Always approve before calling state-changing functions:


// Step 1: Approve
IERC20(token).approve(spender, amount);
 
// Step 2: Call function
contract.functionName(params);

Slippage Protection

Use desired parameter to protect against price movements:


// Allow 1% slippage
uint256 desired = expectedAmount * 99 / 100;

Error Handling

Common revert reasons:

Insufficient balance
Approval not granted
Slippage exceeded
Market not active
Contract paused
Not whitelisted
Investment not matured
