Hello sir! This was the result of private convo (dare I call it DAO lobbying). They feel SC are a critical part of their tech stack and cannot be outsourced.

If you feel up to it, maybe just build it and send it to them so they can play with it. Maybe some subcomponent of that can go to Web3 integration domain. I donāt recall anythin against delegates from applying to SDGP

"Has anyone here used NFTTrader.io? Usually, for bulk transactions, Iāve used that platform. However, Iām not sure if doing that really counts as a security measure for smart contracts. When I inquired about the difficulty, they said it was an intermediate level, not advanced. Given that our current team doesnāt seem to have the capacity to develop this, outsourcing looks like the right approach. I think it would be good to push for this, but are there any issues? I believe most people would agree if we brought this up.
While attracting players is crucial, people who want to buy large plots of land currently face significant hurdles. They could even fall victim to scams. Iāve personally thought about this a lot from The Sandboxās (TSB) perspective. It seems like this issue is lower on the priority list due to factors like disappointed selling pressure from existing partners and very low current LAND sale purchase rates. This is just my personal opinion. Itās quite complicated. But it seems right that we should facilitate transactions.
When I asked OpenSea to re-enable bulk transactions, they said they had closed it because it wasnāt being used. Iāll think about other ideas.

A good observationā¦
Sounds like youāve really been doing the research! Very cool.
As I understand it, TSB will not permit the third-party development of any smart contracts. @Cyril can double confirm that.
But at this point, I think the only path forward for this is pass a SIP requesting increased prioritization by TSB devs.

Hello there,
Iām meeting with TSB tomorrow to try to push for a way. Iāll report back as soon as I have something concrete. Thanks all for your patience.

Just FYI too, Opensea is moving to OS2, which currently affects the way transactions are made.
2 distinct ones are the removal of Deals which actually facilitate private Estate sales, and the removal of dual currencies for collections, i.e no more using SAND as a mode of payment, everything is in ETH.

removal of Deals which actually facilitate private Estate sales
So THATāS why I canāt do deals anymoreā¦I lost a Land deal over the loss of that feature. 
Thank you. I hope you have good news this time.
Iāll explore further to see if there are other directions.

This idea was explored as a possible solution in case direct support from The Sandbox team is difficult.
I also considered how such a feature could be sustainably used in the long term.
Just sharing this as a simple thought.
1. Why OpenSea API & Seaport Are Required
- OpenSeaās default interface does not support bulk LAND sales (e.g., 6x6 , 12x12 or 24x24 estates).
- To enable estate-level or bundled NFT transactions:
Use OpenSea API to fetch LAND metadata (coordinates, size, ownership).- Use Seaport protocol to create signed bundled NFT orders.
A custom external tool is required for user-friendly estate sales.
2. Current Market: No Reliable OTC NFT Service Exists
| Platform | Status |
|---|---|
| NFTTrader.io | Inactive or barely used |
| Swap.kiwi | Limited usage, low trust |
| Reservoir.tools | Good for aggregation, but not true OTC |
| Blur, Sudoswap | No support for trust-based bulk trades |
Currently, there is no trusted OTC platform for high-value NFT assets like LAND, despite strong market demand.
3. If The Sandbox DAO Builds This Tool
| Component | Description |
|---|---|
| Supported Assets | LAND bundles, Estates, high-value NFTs |
| Key Features | Bundle creation, order signing, public fulfillment links, optional NFT-for-NFT swaps |
| Ownership & Ops | DAO-owned, externally developed |
| Revenue Model | - 0.5% to 2% fee per fulfilled order |
- Optional royalties for creators
- Fees payable in SAND or ETH|
Creates a long-term revenue stream for the DAO and improves LAND market liquidity.
4. Realistic Cost, Timeline & Difficulty
| Item | Estimate |
|---|---|
| Development Difficulty | High (Seaport logic, signature handling, UX, security) |
| Budget Range | $30,000 ā $45,000 USD (includes frontend, backend, audits, 6mo ops) |
| Development Timeline | 7ā9 weeks total (2+ months) |
| Dev Team | Professional Web3 development team or verified contributors via grant model |
Developing a DAO-owned OTC NFT trading tool (LAND-focused, Seaport-powered) would cost $30ā45K USD and take ~2 months, but would unlock new liquidity, creator-to-creator trades, and a long-term DAO revenue source in a currently underserved niche.
Iām thinking very seriously about this issue.

I believe you still can use it until 16th June when they fully port over to OS2

Love that youāre thinking about this. But I find it hard to justify spending the money to build and maintain this infrastructure on our own instead of having it be assimilated to TSBās marketplace.
Looking at the amount of transactions thatās happening on OS (minus the recent TSB purchase), its hard to see us ever breaking even from fees.

I agree that this might be somewhat outside the core purpose of the DAO, and I fully understand your concern.
I just wanted to explore different possibilities and angles, in case alternative approaches could be useful down the line.

Yeah me too, in fact I find it very useful on a personal level.
