The Ethereum network
Ethereum is an open network that runs programs. Smart contracts automate rules in code, so a coding mistake can directly affect assets.
Accounts and transactions
Externally owned accounts sign transactions, while contract accounts follow deployed code. Addresses are public, but linking one to a person requires other information.
Gas fees
Gas reflects demand for computation and block space. Wallet estimates are only estimates, so verify network, address, and amount before signing.
Contract risks
Contracts cannot automatically correct errors, and audits do not guarantee safety. Approvals, phishing sites, and counterfeit tokens are recurring risks.
