The @lukso/lsp7-contracts npm package contains useful constants such as interface IDs or ERC725Y data keys related to the LSP7 Standard. You can import and access them as follows.

In JavaScript.

import {
  INTERFACE_ID_LSP7,
  INTERFACE_ID_LSP7_PREVIOUS,
  LSP7_TYPE_IDS,
} from "@lukso/lsp7-contracts";

In Solidity.

import {
  _INTERFACEID_LSP7,
  _INTERFACEID_LSP7_V0_12_0,
  _INTERFACEID_LSP7_V0_14_0,
  _TYPEID_LSP7_DELEGATOR,
  _TYPEID_LSP7_DELEGATEE,
  _TYPEID_LSP7_TOKENSSENDER,
  _TYPEID_LSP7_TOKENSRECIPIENT,
  _TYPEID_LSP7_TOKENOPERATOR
} from "@lukso/lsp7-contracts/contracts/LSP7Constants.sol";

The LSP7_TYPE_IDS object includes type IDs for the following types of notifications:

'LSP7Tokens_SenderNotification';
'LSP7Tokens_RecipientNotification';
'LSP7Tokens_OperatorNotification';
'LSP7Tokens_VotesDelegatorNotification';
'LSP7Tokens_VotesDelegateeNotification';

TypeScript types

import {
    // standard version
    lsp7DigitalAssetAbi,
    lsp7CappedSupplyAbi,
    lsp7MintableAbi,
    lsp7VotesAbi
    // proxy version
    lsp7CappedSupplyInitAbstractAbi,
    lsp7DigitalAssetInitAbstractAbi,
    lsp7MintableInitAbi,
 } from '@lukso/lsp7-contracts/abi';

Foundry deployment

This package includes two Foundry scripts to deploy the LSP7CustomizableTokenInit and LSP7MintableInit implementation contracts.

• scripts/DeployLSP7CustomizableTokenInit.s.sol
• scripts/DeployLSP7MintableInit.s.sol

Set your deployer key first:

export PRIVATE_KEY=0x...
