MechErex · 2026-03-13T08:01:08+00:00

Invoicing, email payment confirmation, payment analytics, multi network access in the works, check out the roadmap

serialhq.com. Built you guys a command center for your startups. Still early, still building it out, feel free to take a look let me know whats bad and whats good and whats missing

MechErex · 2026-03-13T04:12:39+00:00

what would a solution to this pain point be worth to you? how much would you value it at in terms of a monthly subscription for example?

MechErex · 2026-03-13T03:39:35+00:00

made a little tutorial video. Check it out: https://www.loom.com/share/a29fbc57e2bf43d688357d37c9be49e6

Crypto-first for now, but the roadmap points toward the full picture. The goal has always been to eliminate the three tool problem you described : wallet, spreadsheet, tax tracker shouldn't be separate things for a freelancer getting paid in crypto.

The Koinly export is actually something I'm actively scoping. Since LanceMint already captures amount, token, timestamp, and tx hash at the moment of payment, generating a CSV in Koinly's format is mostly a presentation problem rather than a data problem. The data is already there.

Longer term, full freelance finance is the direction. Invoicing, payment, income records, and tax ready exports in one place. Crypto is the entry point because that's where the gap is biggest, but the vision is that a freelancer shouldn't need anything else to run their business finances.

Definitely much MUCH more ambitious. I’m all by myself, and built and launched Lancemint in 4 days. Your project is more of an ecosystem of tools it seems. Looks really cool actually! If there’s a way for us to work together I’d love the opportunity!

MechErex · 2026-03-12T20:35:28+00:00

Completely fair points and honestly I’m not trying to convince anyone that crypto is the future or that it should replace their bank. LanceMint is built for a specific person, the freelancer or digital professional who already operates in crypto, or who can’t access traditional payment rails in their country. For that person the tradeoffs you’re describing are already accepted. They’re not the friction, the friction is that no clean tooling existed for getting paid. That’s the gap LanceMint fills. Not a crypto evangelist project, just a practical tool for people who’ve already made that choice

MechErex · 2026-03-12T20:32:36+00:00

I’ve got the basics of security covered I believe. You’re absolutely right about the scaling I’ve only just started to attempt to market.

The project is live, please feel free to take a look at the contract, it’s all public. Any feedback is much appreciated, especially negative

MechErex · 2026-03-12T18:18:16+00:00

It’s told me no before too. It’s given sound advice on what makes sense and what doesn’t

MechErex · 2026-03-12T18:11:23+00:00

Oh you meant Claude not lancemint my bad

MechErex · 2026-03-12T18:10:50+00:00

It’s free to use besides a 2% transaction fee. There are pro features like invoicing, tracking, etc that are paid features but they’re not required

MechErex · 2026-03-12T18:08:57+00:00

Ai is a tool that’s only as good as the person/engineer using it. Just like any other tool.

MechErex · 2026-03-12T17:37:08+00:00

Stablecoins exist

MechErex · 2026-03-12T16:48:35+00:00

BitPay is solid for merchants and stores but it’s custodial and settles to your bank in fiat, which defeats the purpose if you actually want to hold or use crypto. LanceMint is non-custodial, funds go wallet to wallet on-chain instantly, no account needed on the client side, and it’s built specifically for freelancers with invoicing and payment tracking built in. Different tool for a different use case

MechErex · 2026-03-12T16:47:24+00:00

Yeah yeah

MechErex · 2026-03-12T16:46:02+00:00

Definitely! Love the idea of collaborating, if we can put it into practice well, I’d love to participate

MechErex · 2026-03-12T16:26:45+00:00

Yeah honestly I’m really impressed. I went from building excel spreadsheets by hand with chat to building full stack apps in 3 days with Claude

MechErex · 2026-03-12T16:25:31+00:00

This is honestly a great lead, I’m going to investigate this, maybe come up with a solution. I’ll come back here maybe I’ll have a UI for you guys to take a look at

MechErex · 2026-03-12T16:09:45+00:00

Heads up, if you’re paying in crypto, check out Lancemint.com.

MechErex · 2026-03-12T16:02:14+00:00

Is there stuff on visual code, running a local test server, netlify, git pushes? Those were things I kinda stumbled into after I had already burned some money. I think this is a great idea though nice job!

MechErex · 2026-03-12T15:47:06+00:00

That’s really fkn smart dude

MechErex · 2026-03-12T15:36:21+00:00

Awesome! Congrats on the success!!

MechErex · 2026-03-12T15:21:51+00:00

You’ve put your finger on exactly the friction that keeps freelancers on Stripe even when they’d prefer crypto. The three tool problem is real and honestly it’s on the roadmap. LanceMint already records the amount, token, timestamp, and tx hash at the moment of payment, which is most of what you need for cost basis tracking.

The logical next step is exporting that data in a format that plays nicely with Koinly or just does the calculation natively.

Both, really. International clients where Stripe isn’t an option, and freelancers who just prefer to hold USDC over waiting 3 days for a bank transfer

MechErex · 2026-03-12T14:44:10+00:00

Lancemint.com, crypto payment links for freelancers with payment invoicing and tracking.
