    1. 0.2. Features of ERC-777
    2. 0.4. Benefits

ERC-777 is a token standard on the Ethereum blockchain designed to improve upon the widely used ERC-20 standard. It allows for more efficient token transfers and offers greater flexibility, enabling features like operator-controlled token transfers and enhanced security. Unlike ERC-20, ERC-777 supports advanced functionalities such as “hooks” that let smart contracts interact with tokens in more complex ways.

Features of ERC-777

  • Operator Control: ERC-777 introduces the ability for a third party (operator) to send tokens on behalf of a user, providing more flexibility for use cases like custodial wallets.
  • Token Hooks: Smart contracts can define functions (hooks) to interact with tokens when they are sent or received, improving automation and programmability.
  • Compatibility: ERC-777 is fully compatible with ERC-20, meaning existing ERC-20 tokens can be easily integrated into the ERC-777 ecosystem.

Benefits

ERC-777 improves user experience and flexibility compared to ERC-20, while maintaining compatibility with existing Ethereum applications. It allows for more complex use cases, such as decentralized finance (DeFi) protocols and tokenized assets.
