What are some common errors in smart contracts?
Common errors in smart contracts include reentrancy attacks, integer overflow/underflow, and gas limit issues.
Can you explain reentrancy attacks?
Reentrancy attacks occur when a contract calls another contract and the second contract calls back into the first before it finishes.
How can I prevent integer overflow in my smart contract?
You can prevent integer overflow by using safe math libraries that check for overflow conditions before performing arithmetic operations.
What tools can help me test my smart contracts?
Tools like Truffle, Hardhat, and Remix are great for testing and debugging smart contracts.
