A smart contract on a blockchain is permanent. Once deployed, the bytecode cannot be edited. If it has a bug that drains funds, the bug is permanent too. Two minutes of reading saves you from very expensive mistakes.
Pre-flight checklist
- Read the contract end to end. Ask Claude to summarise what each function does in one sentence.
- Ask "who can call each function?" Functions that move tokens or change ownership should be locked down to specific addresses.
- Ask "is there a way to pause or upgrade this?" If the answer is "no" and you are not 100% sure of the code, do not deploy.
- Deploy on testnet first. Run every flow at least three times. Read every output.
- Only when all of the above is green: deploy on mainnet, with a small initial amount of KLV in the contract, not your full intended supply.
