Ethereum is a blockchain platform that supports digital assets and programmable applications. Its smart contracts are programs that execute actions when predefined conditions are met.
Use cases
Smart contracts can power decentralized finance, digital collectibles, games, and other applications. They reduce the need for some intermediaries but do not remove the need for testing and oversight.
Security matters
Code errors can cause permanent losses. Users should review project documentation, understand transaction permissions, and treat promises of guaranteed returns with caution.
