LSP Smart Contracts ·

The smart contracts reference implementation of the LUKSO Standard Proposals (LSPs).

For more information see Documentation on docs.lukso.tech.

⚠️	This package is currently in early stages of development, use for testing or experimentation purposes only.

Installation

npm

LSP smart contracts are available as a npm package.

npm install @lukso/lsp-smart-contracts

cloning the repository

Alternatively you can also clone the repository and install its dependencies to start using the smart contracts.

$ git clone https://github.com/lukso-network/lsp-smart-contracts.git
$ cd ./lsp-smart-contracts
$ npm install

Testing

For detailed instructions on how to run tests, please refer to our Testing Guide.

Usage

in Javascript

You can use the contracts JSON ABI by importing them as follow:

import LSP0ERC725Account from "@lukso/lsp-smart-contracts/artifacts/LSP0ERC725Account.json";

const myContract = new web3.eth.Contract(
  LSP0ERC725Account.abi,
  "",
  defaultOptions
);

in Solidity

import "@lukso/lsp-smart-contracts/contracts/LSP0ERC725Account/LSP0ERC725Account.sol";

contract MyAccount is LSP0ERC725Account {
  constructor(address _newOwner) LSP0ERC725Account(_newOwner) {}
}

Deployment via hardhat

You can find more infos on how to deploy the contracts via hardhat in the DEPLOYMENT page.

Available Constants & Types

The @lukso/lsp-smart-contracts npm package contains useful constants such as Interface IDs or ERC725Y Data Keys related to the LSP Standards. You can import and access them as follow:

import {
  INTERFACE_IDS,
  ERC1271,
  OPERATIONS,
  SupportedStandards,
  ERC725YDataKeys,
  PERMISSIONS,
  ALL_PERMISSIONS,
  LSP8_TOKEN_ID_SCHEMA,
  LSP25_VERSION,
  ErrorSelectors,
  EventSigHashes,
  FunctionSelectors,
  ContractsDocs,
  StateVariables,
} from "@lukso/lsp-smart-contracts";

Note: we also export it as @lukso/lsp-smart-contracts/constants or @lukso/lsp-smart-contracts/constants.js to keep it backward compatible.

It also includes constant values Array data keys to retrieve both the array length and for index access.

'LSP5ReceivedAssets[]': {
    length: '0x6460ee3c0aac563ccbf76d6e1d07bada78e3a9514e6382b736ed3f478ab7b90b',
    index: '0x6460ee3c0aac563ccbf76d6e1d07bada',
},

Note for Hardhat Typescript projects

If you are trying to import the constants in a Hardhat project that uses Typescript, you will need to import the constants from the dist folder directly, as shown in the code snippet:

import { INTERFACE_IDS } from "@lukso/lsp-smart-contracts/dist/constants.cjs.js";

// This will raise an error if you have ES Lint enabled,
// but will allow you to import the constants in a Hardhat + Typescript based project.
const LSP0InterfaceId = INTERFACE_IDS.LSP0ERC725Account;

See the issue related to Hardhat Typescript + ES Modules in the Hardhat docs for more infos.

Typescript types

The following additional typescript types are also available, including types for the JSON format of the LSP3 Profile and LSP4 Digital Asset metadata.

import {
  LSP2ArrayKey,
  LSPSupportedStandard,
  LSP6PermissionName,
  LSP3ProfileMetadataJSON,
  LSP3ProfileMetadata,
  LSP4DigitalAssetMetadataJSON,
  LSP4DigitalAssetMetadata,
  ImageMetadata,
  LinkMetadata,
  AssetMetadata,
} from "@lukso/lsp-smart-contracts";

Audits

NB: dates of the audit reports use the american date format YYYY-MM-DD.

The following audits and formal verification were conducted. All high-level issues were addressed, or were not deemed as critical.
