PropXchain - UK Property Conveyancing on ICP (Looking for Community Feedback)

Developers Showcase
1

Hey everyone,

I’m building PropXchain - a platform that puts UK property transactions on the Internet Computer. Before I go down the NNS funding route, I’d really value some honest feedback from the community.

What’s the problem?

UK property transactions are honestly a mess. You’ve got solicitors, estate agents, mortgage brokers, and buyers/sellers all working off different spreadsheets and emails. Nobody knows what’s actually happening. Transactions fall through because someone forgot to chase a form. It takes months when it should take weeks.

The kicker? There’s zero accountability. When something goes wrong, everyone points fingers because there’s no single source of truth about who did what and when.

Why ICP?

I looked at other blockchains but ICP kept ticking boxes the others couldn’t:

Internet Identity - This one’s huge. UK property transactions involve real people with real money. They’re not crypto-native. They won’t touch MetaMask. Internet Identity gives us proper authentication without asking grandma to manage seed phrases.

On-chain audit trail - Everything that happens in a transaction gets recorded immutably. Who uploaded which document, when they did it, what Oscar AI found when it scanned the legal forms. When things go pear-shaped (and in property, they often do), we’ve got receipts.

For settlements - Property deposits and payments will hopefully be done with ShieldPay, verifiable by all parties. No more “the cheque’s in the post” nonsense.

Canister architecture - The whole platform runs on canisters. Front-end, back-end, document verification, the lot. It’s properly decentralised, not just blockchain-flavoured Web2.

What’s built so far?

We’ve got a working beta:

  • Transaction management (buyers, sellers, solicitors, agents all in one place)
  • Document upload with on-chain hash verification (GDPR-compliant - only hashes on-chain)
  • Oscar AI - scans legal forms (TA6, TA7, etc.) and flags issues automatically
  • Real-time status tracking for everyone involved
  • Property intelligence (flood risk, planning applications, price history from UK gov data)
  • It’s live, it works, and we’re onboarding the first pilot users now.

What I’m asking

  • I’m planning to submit an NNS proposal for development funding to scale this properly. But before I do that, I want to make sure I’m not missing something obvious or building in a way that doesn’t fit with how the ICP community thinks these things should work.

  • Questions I’m wrestling with:

  • Is there a better approach than NNS motion proposals for this stage (beta with early users)?

  • Are there other ICP projects in the legal/property space I should be talking to?

  • Any glaring technical concerns about putting sensitive property data on-chain (even as hashes)?

  • Appreciate any thoughts - particularly the critical ones. Much rather find out what I’ve missed now than after submitting a proposal.

Cheers,

Marc

Idea is nice, but i think you should ask funding from your goverment. Dfinity most likely wont fund it and SNS wont be sustainable.

Thanks for the feedback! Just to clarify - I’m looking at NNS development grants rather than launching an SNS. You’re right that we’re nowhere near ready for token economics yet.

Good shout on government funding though. Are you aware of specific UK programmes that fund blockchain property tech? We’ve looked at Innovate UK but they tend to shy away from anything crypto-related.

May I ask, why you cannot approach a bank for a traditional business loan and you must approach a decentralized blockchain?

We are building this system on the ICP blockchain, so thought that help from the blockchain would be good as it will bring users to the icp blockchain. Using Internet Identity means all users will log in and then start to be familiar with ICP. I am looking at other revenue streams Governement, Business lending etc but really like what the IC is doing and what it stands for, one of the reasons i built Propxchain is to knock down walls and make things transparent.

There is no proposal for this, and it’s not something the NNS would submit to (it would be rejected). The closest there is to this is launching an SNS, and even then the funding doesn’t come from some sort of NNS treasury or mint, it comes from market participants willing to invest in return for co-ownership. I think you’re unlikely to get what you’re looking for going the SNS route, because people will be sceptical of the revenue model until revenue is already coming in.

What are you actually asking for funding for? If it’s finished and ready for customers, then those are your source of funding. If that funding isn’t there, then a viable product isn’t there (though it sounds cool). Sometimes the world just isn’t ready for what it needs, even though it needs what it isn’t ready for.

Thanks for the feedback, I’m at the stage of approaching paying users so fingers crossed this goes well. It was more of an enquiry as the grant program affinity were running has been removed and while the app is nearly ready and marketing, consultations with users is about to start, we were hoping on funding to help with doing Property shows/expos. I currently have a full time job not in development and the funding would help release me to concentrate full time on getting Propxchain over the line. Thank you for your advice.

I think many people are in this position. I wish you luck!

The application is beautifully presented -

While I know very little about property it’s quite clear you spend a lot of time and consideration into your idea.

I forwarded your link to a friend in UK to have a look, she recently angel invested in something similar.

She will take a look.

Keep up the great work
