Expand description

A Delegate is a webassembly code designed to act as an agent for the user on Freenet. Delegates can:

  • Store private data on behalf of the user
  • Create, read, and modify contracts
  • Create other delegates
  • Send and receive messages from other delegates and user interfaces
  • Ask the user questions and receive answers

Example use cases:

  • A delegate stores a private key for the user, other components can ask the delegate to sign messages, it will ask the user for permission
  • A delegate monitors an inbox contract and downloads new messages when they arrive
