Aztec Standards

Aztec Standards is a comprehensive collection of reusable, standardized contracts for the Aztec Network. It provides a robust foundation of token primitives and utilities that support both private and public operations, empowering developers to build innovative privacy-preserving applications with ease.

Table of Contents

• Dripper Contract
• Token Contract
• Tokenized Vault Contract
• NFT Contract
• Escrow Standard Contract & Library
• Future Contracts

Dripper Contract

The Dripper contract provides a convenient faucet mechanism for minting tokens into private or public balances. Anyone can easily invoke the functions to request tokens for testing or development purposes.

Token Contract

The Token contract implements an ERC-20-like token with Aztec-specific privacy extensions. It supports transfers and interactions explicitly through private balances and public balances, offering full coverage of Aztec's confidentiality features.

We published the AIP-20 Aztec Token Standard to the forum. Feel free to review and discuss the specification there.

Tokenized Vault Contract

The Token contract can be configured to function as a Tokenized Vault, allowing it to issue yield-bearing shares that represent deposits of an underlying asset. To enable this mode, deploy the contract using the constructor_with_asset() initializer. The underlying asset contract must be an AIP-20–compliant token, and the vault itself issues AIP-20–compliant share tokens to depositors.

We published the AIP-4626: Tokenized Vault Standard to the forum. Feel free to review and discuss the specification there.

NFT Contract

The NFT contract implements an ERC-721-like non-fungible token with Aztec-specific privacy extensions. It supports transfers and interactions through both private and public ownership, offering full coverage of Aztec's confidentiality features for unique digital assets.

Escrow Standard Contract & Library

The Escrow Standard contains two elements:

• Escrow Contract: a minimal private contract designed to have keys with which authorized callers can spend private balances of tokens and NFTs compliants with AIP-20 and AIP-721, respectively.
• Logic Library: a set of contract library methods that standardizes and facilitates the management of Escrow contracts from another contract, a.k.a. the Logic contract.

To see examples of Logic contract implementations, such as a linear vesting contract or a clawback escrow contract, go to aztec-escrow-extensions.

Future Contracts

Additional standardized contracts (e.g., staking, governance, pools) will be added under this repository, with descriptions and function lists.
