Locking Specific Token IDs

This example demonstrates how to permanently lock approvals for specific token IDs while keeping other approvals updatable.

Overview

By targeting specific tokenIds, you can freeze approvals for those tokens permanently while allowing updates to approvals for other token IDs.

Lock Token IDs 1-100

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

const collectionPermissions = {
    canDeleteCollection: [],
    canArchiveCollection: [],
    canUpdateStandards: [],
    canUpdateCustomData: [],
    canUpdateManager: [],
    canUpdateCollectionMetadata: [],
    canUpdateValidTokenIds: [],
    canUpdateTokenMetadata: [],
    canUpdateCollectionApprovals: [
        {
            // Which approvals does this permission apply to? Approvals must match ALL criteria.
            fromListId: 'All',
            toListId: 'All',
            initiatedByListId: 'All',
            transferTimes: FullTimeRanges,
            tokenIds: [
                {
                    start: '1',
                    end: '100', // Only targets tokens 1-100
                },
            ],
            ownershipTimes: FullTimeRanges,
            approvalId: 'All',

            // What is status of this approval at any given time? (Unhandled = soft-enabled)
            permanentlyPermittedTimes: [],
            permanentlyForbiddenTimes: FullTimeRanges, // Permanently locked
        },
    ],
};

Lock All Tokens EXCEPT 1-100

const collectionPermissions = {
    canDeleteCollection: [],
    canArchiveCollection: [],
    canUpdateStandards: [],
    canUpdateCustomData: [],
    canUpdateManager: [],
    canUpdateCollectionMetadata: [],
    canUpdateValidTokenIds: [],
    canUpdateTokenMetadata: [],
    canUpdateCollectionApprovals: [
        {
            // Which approvals does this permission apply to? Approvals must match ALL criteria.
            fromListId: 'All',
            toListId: 'All',
            initiatedByListId: 'All',
            transferTimes: FullTimeRanges,
            tokenIds: [
                {
                    start: '101',
                    end: '18446744073709551615', // All tokens except 1-100
                },
            ],
            ownershipTimes: FullTimeRanges,
            approvalId: 'All',

            // What is status of this approval at any given time? (Unhandled = soft-enabled)
            permanentlyPermittedTimes: [],
            permanentlyForbiddenTimes: FullTimeRanges, // All others permanently locked
        },
    ],
};

Implementation

const createCollection = {
    // ... other collection fields
    collectionPermissions,
    collectionApprovals: [
        {
            tokenIds: [{ start: '1', end: '50' }],
            // ... this approval will be locked if it overlaps with permission criteria
        },
        {
            tokenIds: [{ start: '150', end: '200' }],
            // ... this approval's updateability depends on configuration
        },
    ],
};

Use Cases

• Lock Founder Tokens: Prevent modification of special token 1-100 transfer rules

• Preserve Rare Items: Keep limited edition tokens (1-100) immutable

• Tier-Based Control: Lock specific tiers while allowing others to evolve

Important Notes

⚠️ ID Range Targeting

The permission only applies to approvals that overlap with the specified token ID ranges. Approvals targeting token IDs outside the range remain updatable.
