Generalized Accounts

Generalized Accounts

Generalized Accounts in æternity offer enhanced flexibility in how transactions can be authenticated, moving beyond traditional public-private key signatures. This powerful feature allows users to define custom logic for transaction authorization through smart contracts, enabling various authentication schemes such as multi-signature setups, spending limits, specific transaction type restrictions, or even alternative cryptographic signing algorithms like ECDSA used in Bitcoin and Ethereum.

The Generalized Accounts documentation provides comprehensive technical specifications for Generalized Accounts, including detailed examples of implementation. You'll find practical examples such as an ECDSA authentication contract that allows users to sign æternity transactions with their Bitcoin private keys, along with important security considerations and best practices for implementing authentication functions in these contracts.
