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.
Prerequisite: Start an Aztec local network in a separate terminal:
aztec start --local-networkTests: yarn test runs Noir and JS tests. JS tests expect the network to be running at http://localhost:8080 (or NODE_URL).
Benchmarks: yarn bench connects to the same running network.
Set NODE_URL to override the default (e.g. http://localhost:9000).

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.

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.

The Vault contract is a standalone yield-bearing vault that holds an underlying AIP-20 asset and issues AIP-20 share tokens to depositors. The vault and shares token are separate contracts — the vault manages deposit/withdraw/redeem logic while delegating share token operations (mint, burn, transfer) to an external AIP-20 Token contract configured with the vault as its minter.
We published the AIP-4626: Tokenized Vault Standard to the forum. Feel free to review and discuss the specification there.

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.

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