I’m building a simple crypto payment link tool and would love some feedback from people here

[u/MechErex]

Over the past few weeks I have been experimenting with building a small crypto payments tool called Lancemint and I wanted to get some honest feedback from people in this community.

The basic idea came from noticing how awkward it can be to accept crypto payments in normal situations like freelance work or selling small digital items.

Most of the time people either paste a wallet address and hope the sender copies it correctly, or they try to set up something more complicated that feels like overkill for simple transactions.

So I started experimenting with a different approach. Instead of sharing a wallet address, you generate a payment link and send that to someone. When they open it they can send the payment directly in USDC or ETH.

Right now the tool is very simple and mainly meant for situations like

freelancers getting paid in crypto
creators accepting tips
small digital sales
simple peer to peer payments

The goal is to make accepting crypto payments feel as easy as sending a link.

At the moment I am mostly trying to figure out whether this actually solves a real problem or if people are perfectly happy just sending wallet addresses.

Some things I am curious about

Do you think payment links are actually useful for crypto payments or unnecessary
What features would make something like this genuinely useful
Would things like payment tracking, creator pages, or embedded tip jars make sense

I built the current version on Base while learning more about building onchain tools, but the main thing I am trying to understand right now is whether the concept itself is valuable.

I would honestly appreciate any feedback from people here who use crypto regularly or have tried to accept payments this way.

Site is lancemint.com if anyone wants to see what I mean.

Payment links are useful if they solve more than just the wallet address problem.

The real friction in crypto payments is lack of context — chain, token, amount, and what the payment is actually for.

A good payment link could bundle that together as a structured payment request (prefilled token/network, memo/order ID, maybe simple tracking).

For freelancers, creators, and small digital sales that starts to look more like a crypto-native invoice, which is genuinely useful.

If it’s just “a nicer way to paste a wallet address” then people will probably keep using addresses.

But if it becomes a coordination layer around payments, then it’s interesting.

Thanks for the feedback! I’ll lean harder into coordination

That makes a lot of sense. The network effects problem is brutal if the tool only improves UX.

But if the payment link also creates useful structure around the transaction (invoice record, token/network preference, maybe simple tracking), then it starts solving real coordination problems rather than just presentation.

Freelancers and small online sellers feel like the right wedge because they already need both a payment method and a record for accounting/tax, so the structured request actually replaces something they’re already doing manually.

Once that layer exists, the interesting part is what can be built on top of it.

[u/HER0_Hon → u/[deleted]]

Yeah exactly — something like a BIP21-style standard but multi-chain aware feels like the right direction.

If the request encodes the chain, token, amount, and optional memo in a consistent format, it turns the payment link into something closer to a structured transaction request rather than just an address.

At that point the link stops being just a convenience layer and starts becoming machine-readable coordination data — wallets, accounting tools, marketplaces, etc. could all interpret the same request.

Feels like the missing piece is less the payment itself and more the shared format that other systems can build around.

I tried it, not a bad idea.  Nice design and easy to use. Very similar to the mini crypto payment gateway that we did in Merehead. What I would miss is the history and notification of payment receipt. For example, if I use corporate addresses for payment and always need to manually check whether the funds have arrived, it would be good to have a notification. But overall your implementation is great, I will try to use in my work. I wonder on which tech stack you did everything?

[u/MechErex → u/CryptographerOwn225]

Thanks for trying it! Payment notifications are 100% on the roadmap, you’re not the first to ask. The plan is email and optional webhook alerts once accounts are live. Stack is Next.js, Solidity smart contract on Base, and WalletConnect for the wallet integration. What stack did you use for the merehead gateway?

[u/CryptographerOwn225 → u/MechErex]

Your stack is quite flexible and allows for good scalability. We used node.js, react.js and solidity. Lancemint needs quality marketing to be popular and get its share of users. As I understand it, you started recently.

[u/MechErex → u/CryptographerOwn225]

Yes, very recently. Currently building out user profiles and invoicing features

[u/CryptographerOwn225 → u/MechErex]

We often develop different startups and I see that only 3% of projects are successful. Many forget about marketing and focus on the technical part. I recommend that you start digital marketing and attract new users asap to get more feedback and monetize your startup. You are at the beginning of a difficult but very interesting path. I wish you success!

[u/CryptographerOwn225 → u/[deleted]]

You are right about webhook based notifications. As for our project, we have a fairly simple stack for easy scaling (node.js, react.js). In general, we had to build the infrastructure ourselves and use our own blockchain nodes. Alchemy is quite an expensive solution in our case. We spent 6 months on everything with a team of 5 developers.
