Keep these points about smart contracts in mind:
1) The Ethereum mainnet launched in July 2015 and was one of the earliest public blockchains capable of running Turing-complete smart contracts.
2) Once deployed, a contract's code usually can't be modified directly, though many projects use upgradeable proxy contracts to retain the ability to upgrade.
3) Before interacting with an unfamiliar contract, try it with a small amount first. Don't put in a large amount of funds right away.
Calling contracts on Ethereum requires $ETH to pay Gas. The current price is 2409.98.
