This is because you cannot understand the actions of a smart contract without executing it. Synchronizing Blockchain Internals and Externals Smart contracts operate exclusively within the blockchain's data, reading and writing information stored on-chain. This limitation does not prevent the creation of valuable applications, such as multi-signature wallets or tokens like ERC-20 and ERC-721, which rely solely on on-chain data. However, most practical applications also require interaction with off-chain systems. Take cryptocurrency exchanges, for example. Exchanges facilitate converting ETH into fiat currency or vice ver...
