Locking Valid Token IDs

This example demonstrates how to control updates to the validTokenIds field, either locking it permanently or allowing controlled expansion. The validTokenIds field is used to control which token IDs are considered valid for the collection.

Overview

The canUpdateValidTokenIds permission controls whether the valid token ID ranges can be modified.

Lock Valid Token IDs Forever

const FullTimeRanges = [
    {
        start: '1',
        end: '18446744073709551615',
    },
];

const collectionPermissions = {
    canDeleteCollection: [],
    canArchiveCollection: [],
    canUpdateStandards: [],
    canUpdateCustomData: [],
    canUpdateManager: [],
    canUpdateCollectionMetadata: [],
    canUpdateValidTokenIds: [
        {
            // Which token IDs does this permission apply to?
            tokenIds: FullTimeRanges, // All token IDs

            // What is status of this permission at any given time?
            permanentlyPermittedTimes: [],
            permanentlyForbiddenTimes: FullTimeRanges, // Never allowed to update
        },
    ],
    canUpdateTokenMetadata: [],
    canUpdateCollectionApprovals: [],
};

Lock Token IDs 1-100, Allow Future Expansion

const collectionPermissions = {
    canDeleteCollection: [],
    canArchiveCollection: [],
    canUpdateStandards: [],
    canUpdateCustomData: [],
    canUpdateManager: [],
    canUpdateCollectionMetadata: [],
    canUpdateValidTokenIds: [
        {
            // Which token IDs does this permission apply to?
            tokenIds: [
                {
                    start: '1',
                    end: '100', // Only applies to tokens 1-100
                },
            ],

            // What is status of this permission at any given time?
            permanentlyPermittedTimes: [],
            permanentlyForbiddenTimes: FullTimeRanges, // Token IDs 1-100 locked forever
        },
        // Token IDs 101+ remain soft-enabled (can be updated by manager)
    ],
    canUpdateTokenMetadata: [],
    canUpdateCollectionApprovals: [],
};

Implementation

const createCollection = {
    // ... other collection fields
    collectionPermissions,
    validTokenIds: [
        {
            start: '1',
            end: '100', // Initial valid range
        },
    ],
};

Important Notes

⚠️ Token ID Targeting

• Permissions only apply to the specified token ID ranges

• Unspecified ranges remain soft-enabled for manager updates

• Cannot reduce valid token IDs once locked (only expansion possible for unlocked ranges)
