Relationship with Decentraland: I have already built in Decentraland

Prior Decentraland work:

GitHub - DOCTORdripp/rituals: Burn2Upgrade Wearables by Emm & DOCTORdripp · GitHub GitHub - DOCTORdripp/KeepAway: A proof of concept for Keep Away game in Decentraland · GitHub GitHub - DOCTORdripp/cavern: a Decentraland Game Jam 2023 Submission by DOCTORdripp · GitHub

Why build for Decentraland?

Decentraland lacks accessible infrastructure for creators to manage NFT distribution and upgrade mechanics at scale. While wearables are core to the ecosystem, there is no simple way to airdrop to holders, run burn-to-upgrade campaigns, or create reward loops without custom development. MintOps provides open-source, no-code tools that empower creators to build these systems directly on Polygon, fully aligned with Decentraland’s wearable economy. This strengthens creator capabilities, increases engagement, and enables new types of experiences native to the platform.

Prior similar work:

I’ve already built and deployed systems that directly power the core mechanics proposed in MintOps. The primary example is the DOCTORdripp rewards platform, a live burn-to-upgrade system that allows users to send NFTs to a destination and receive upgraded items in return. This includes backend minting, wallet interactions, event logging, and a working upgrade flow used in production. It also supports randomized reward outcomes, which will translate directly into MintOps’ RNG campaign system. I also built a Polygon NFT holder aggregation tool (public GitHub), which fetches and processes holder data for airdrop targeting. This forms the foundation of the airdrop module. Additionally, I’ve implemented real-time blockchain event handling via WebSockets and built full-stack apps using Vercel and Supabase, demonstrating my ability to deliver scalable, production-ready tools.

The project

What is MintOps: Open-Source NFT Airdrop & Burn-to-Upgrade Platform?

MintOps is an open-source web platform that gives Decentraland creators simple, no-code tools to manage NFT distribution and upgrade mechanics. It allows users to aggregate wallet holders from any Polygon collection, run large-scale airdrops, and create burn-to-upgrade campaigns with optional randomized rewards. The platform is designed for wearable creators, game builders, and community managers who currently need custom development to run these systems. MintOps removes that barrier by handling minting, batching, gas abstraction, and campaign logic through a credit-based system. This solves a key gap in Decentraland: there is no accessible infrastructure for reward loops, progression systems, or scalable distribution. MintOps enables these mechanics natively, helping creators build more engaging and dynamic experiences.

How does this align with the AI-assisted tooling theme?

MintOps aligns with the AI-assisted tooling theme through its development approach and open-source accessibility. The platform is being built using AI-assisted coding workflows, enabling rapid iteration, reduced development time, and efficient implementation of complex Web3 infrastructure such as NFT distribution systems, relayers, and upgrade mechanics. By leveraging AI in the engineering process, MintOps demonstrates how advanced tooling can be developed faster and more efficiently, while remaining transparent and extensible. The full codebase will be open source, allowing other developers in the Decentraland ecosystem to learn from, reuse, and build upon the system.

Who is this for?

MintOps is designed primarily for Decentraland creators, including wearable designers, game developers, and experience builders who need simple tools to manage NFT distribution and upgrade mechanics without custom development. It also serves studios and community operators running campaigns, events, or reward systems, as well as developers who want an open-source foundation to build on or integrate into their own projects. By supporting both non-technical creators and technical teams, MintOps becomes a shared infrastructure layer for the broader Decentraland ecosystem.

What problem does this solve?

Decentraland creators lack simple tools to distribute NFTs or run upgrade systems at scale. Airdrops, holder targeting, and burn-to-upgrade mechanics currently require custom development, making them inaccessible to most creators. This limits engagement, reward systems, and progression mechanics. MintOps removes this bottleneck by providing a no-code, open-source solution for NFT distribution and upgrades.

Deliverables (90 days)

A working open-source MVP of MintOps will be delivered within 90 days. This includes a public web app that allows creators to connect a wallet, aggregate NFT holders from a Polygon contract, and execute airdrop campaigns using a credit-based system. The MVP will also include a burn-to-upgrade campaign builder with direct minting, configurable reward outputs, and integrated RNG logic. A backend relayer system will handle batching, gas abstraction, and transaction execution. Much of the core logic has already been built and tested in prior systems and will be refactored into a clean, public-facing platform. Deliverables include full documentation, deployment guides, and a public GitHub repository so developers can run, modify, or extend the system.

Open source

MintOps will be fully open source on GitHub, including the frontend, backend relayer, smart contract, and documentation. The codebase will be modular and well-documented so developers can deploy their own instance, integrate specific components, or extend functionality. Clear setup guides and examples will make it easy for others in the Decentraland ecosystem to reuse and build on the system.

Success metrics

Success will be measured by adoption and usage within the Decentraland ecosystem. Key metrics include number of creators using the platform, number of campaigns launched (airdrops and burn-to-upgrade), total NFTs distributed or upgraded, and repeat usage by creators. Additional signals include GitHub engagement (stars, forks), community feedback, and the number of developers deploying or extending the open-source codebase.

VOXEL — Technical Feasibility

VOXEL — Round 1 Questions (Revised)

@doctordripp — Three focused questions on flow, security, and feasibility:

Question 1: DCL Scene Integration Flow

Walk me through the end-to-end user flow for a burn-to-upgrade campaign that a DCL creator would deploy:

  • Does this happen in-scene (user clicks something in a DCL world) or external (user goes to a web dashboard)?
  • If in-scene: How does the SDK7 scene communicate with MintOps? Via executeTask HTTP calls to your backend? Direct smart contract calls?
  • If external: How does a DCL scene know that a user completed an upgrade? Does MintOps provide an API that scenes can query?

Concrete example: I’m a wearable creator. I want users who own “Basic Sword” to burn it in my scene and receive “Epic Sword” randomly (50% chance) or “Legendary Sword” (10% chance). How does MintOps enable this?

Question 2: Security & Race Conditions

You mention “atomic db locking for full security and race-condition checks.”

For burn-to-upgrade campaigns with RNG (randomized rewards):

  • How do you prevent a malicious user from front-running the transaction or manipulating the RNG outcome?
  • Where does the randomness come from? (On-chain VRF like Chainlink? Pseudo-random from block hash? Server-side RNG?)
  • What happens if a user submits multiple burn transactions simultaneously before the first one completes?
  • How do you ensure the creator’s NFT supply doesn’t get exhausted by race conditions (e.g., 100 users burn simultaneously but you only have 50 upgraded NFTs left)?

Question 3: Smart Contract Architecture & Feasibility

Your budget includes $2,500 for smart contract development, but you also say the system is “already complete” from your rewards platform.

  • Is the burn-to-upgrade smart contract already deployed and audited? If so, where can I see it (contract address on Polygon)?
  • Does the contract handle any Polygon NFT (ERC-721/ERC-1155) or is it specific to DCL wearables?
  • For RNG-based upgrades: How is the reward determined on-chain vs. off-chain? (This matters for trust/verifiability)
  • Gas costs: What’s the estimated gas cost per burn-to-upgrade transaction? And how does your $2,000 gas subsidy budget translate to number of transactions covered?

That’s it. Answer these three and I’ll have what I need to properly evaluate feasibility and security.

Hi @DCLVoxel - I’ve prepared responses to your questions below:

Question 1: DCL Scene Integration Flow

MintOps supports both a web dashboard and in-scene Decentraland interaction, with in-scene usage included in the MVP.

Creators configure burn-to-upgrade campaigns in the MintOps web dashboard by defining the source NFT, eligibility rules, reward options, and probability distribution.

Users can initiate upgrades either:

  • in-scene (e.g., interacting with an SDK7 upgrade station), or

  • via a smart wearable UI

In both cases, the scene or wearable communicates with MintOps using executeTask HTTP calls to:

  • check eligibility (ownership of required NFT)

  • fetch campaign configuration

  • retrieve upgrade results

No private keys or minting logic are handled client-side.

Example:

A creator defines:

  • Basic Sword → required source item

  • Epic Sword → 50%

  • Legendary Sword → 10%

  • remaining percentage → configurable fallback

A user interacts with an in-world upgrade station. The scene calls MintOps to verify ownership of Basic Sword. If eligible, the user signs a transaction to the shared MintOps contract.

The contract receives the NFT into escrow and emits an upgrade request event. MintOps detects the event, validates the campaign, applies interleaved RNG, reserves the reward, mints the selected item, records the result, and then finalizes the request on-chain.

Upon finalization, the contract routes the original NFT to the configured burn or destination address. The scene or wearable queries MintOps to display the result, unlock features, or update the UI in real time.

Question 2: Security & Race Conditions

MintOps separates responsibility across contract, backend, and database to ensure security and prevent race conditions.

  • Contract: escrows the source NFT, emits upgrade request events, and finalizes routing

  • Backend: validates campaign rules, applies RNG, reserves supply, and mints rewards

  • Database: enforces atomic locking and prevents duplicate or conflicting processing

RNG is server-side for the MVP using a proven interleaved RNG approach. The outcome is only determined after a valid on-chain escrow event is confirmed and cannot be influenced by user input.

Each upgrade request is processed exactly once using atomic locks keyed by:

  • transaction hash

  • wallet + source contract + token ID

  • campaign ID

This prevents duplicate claims and ensures simultaneous submissions cannot result in multiple rewards for the same NFT.

Reward supply is reserved atomically before minting. If multiple users submit concurrently and supply is limited, only successfully reserved requests proceed.

To protect users, the contract holds the source NFT in escrow until the reward is successfully minted and the upgrade is finalized. If the process fails or supply is unavailable, the user can reclaim the escrowed NFT after a timeout, ensuring no loss of assets.

Front-running risk is minimized because:

  • the reward is not pre-determined or user-controlled

  • RNG is applied only after transaction confirmation and locking

Question 3: Smart Contract Architecture & Feasibility

The current DOCTORdripp rewards platform does not use a custom smart contract. Instead, it uses a real-time WebSocket-based monitoring system: users send NFTs to configured burn or destination addresses, and the backend listens for transfer events from approved collections, validates them, applies RNG, mints rewards, and logs results.

This system is already running in production and is chain-agnostic across major EVM networks.

The shared MintOps contract is not yet deployed or audited and is part of the proposed grant scope. The goal is to evolve the existing system into a more structured on-chain architecture using escrow, explicit upgrade request events, and controlled finalization.

The contract will:

  • receive source NFTs into escrow

  • emit upgrade request events

  • allow backend-triggered finalization after reward minting

  • route NFTs to burn or configured destination addresses

  • allow user reclaim if finalization fails or times out

The contract will not determine rewards or mint them directly. Reward selection is handled off-chain by the backend after the escrow event is confirmed. This keeps the MVP practical while allowing future upgrades such as verifiable randomness.

The initial implementation will focus on Decentraland wearable upgrade flows, with architecture designed to support standard Polygon NFTs (ERC-721 first, with ERC-1155 support where feasible). The existing multi-chain capability provides a clear path for expansion beyond Polygon.

Gas costs:
Based on current Polygon conditions, typical transaction costs are approximately $0.005 at ~140 gwei, and up to $0.01 during higher activity, though this may vary with network usage. The $2,000 gas subsidy is intended to support a large volume of early transactions and validate real-world usage during launch.

ORACLE — Final Recommendation

This proposal is not approved, but the decision reflects the program’s current sequencing priorities rather than concerns about the project’s quality. The grants program is focusing funding on content creation — the scenes and experiences that bring people into Decentraland. MintOps is distribution and upgrade infrastructure for items creators already have, which becomes more valuable as the content base grows. We’d rather revisit tooling like this once that foundation has more depth.

Additionally, the architecture introduces ongoing operator dependencies (hosted backend RNG, shared smart contract that’s part of the proposed scope rather than already deployed and audited), and $2.5K over 90 days to design, build, test, and ideally audit a contract handling NFT burns is tight.

Acknowledgments: @doctordripp ships work. The DOCTORdripp rewards platform is in production, the technical track record is real, and the response to VOXEL’s questions was detailed, honest, and architecturally sound. The idea is genuinely good — no-code burn-to-upgrade and airdrop tooling would be valuable to the ecosystem at the right time. Open-source with a clear path from existing production code is the right shape for ecosystem infrastructure.
