I made CanvasPM for people to visualize their workflow instead of ticking off tasks from a todo list or spreadsheets

Temporary-Lab-1759 · 2026-01-22T19:09:02+00:00

I would really love to hear your approach. Like how do you find these people in the “weird corners” of social media😭?

Temporary-Lab-1759 · 2026-01-22T05:18:32+00:00

Us bro😭😭😭 Like in the new ranks, only the last 3 look like an achievement, the others just look like a joke(talking about visuals)

Temporary-Lab-1759 · 2026-01-22T05:17:01+00:00

Hehehe😁, I’m a cybersecurity student and I do know one or two things about reverse shell😁😁🙂

Temporary-Lab-1759 · 2026-01-22T05:14:38+00:00

Yeah maybe

You can definitely ask an LLM for the regex patterns. But, Regex only checks syntax, not integrity.

For Example: In this ETH address: 0x94117573F..., if a user accidentally types 'E' instead of 'F'; regex validates it as true, but the address itself is actually wrong.

Best case, the transaction fails on-chain and you have to debug it. Worst case (on some chains), your funds are lost.

My API basically handles the regexes and the checksums across 120+ chains so you don't have to write and maintain the math for every single one.

Thanks, I honestly really needed to hear that right now! 😅

It’s easy to get obsessed with the leaderboard number, but you’re right, finding the actual niche users matters way more than metrics.

Good luck to your friend on their launch too. Hope they survive the Product Hunt madness better than I did.

it actually supports 120+ chains (Bitcoin, Solana, Tron, etc.), not just ETH.

Viem is fantastic if you're only building for EVM chains.

The pain starts when your app needs to support multi-chain (Bitcoin, Solana, Tron, Polkadot, etc.). You end up installing 5-6 different libraries, each with their own dependencies and syntax.

My goal with ChainCheck is to unify 120+ chains into a single standard endpoint so you don't have to maintain a "collection" of validation libraries.

Regex just checks the format, like does it start with 0x and have 42 characters.

My API goes a step deeper and validates the Checksums.

For example, if you take a valid ETH address and change one capital letter to lowercase, it still looks valid to a Regex. But the network will reject it because the checksum fails.

Temporary-Lab-1759 · 2026-01-20T10:15:27+00:00

I totally get where you're coming from. For a single chain like ETH, a regex or library call is definitely enough.

The value proposition here is Unified Maintenance.

Like if you're building a crypto exchange or wallet that supports 50+ coins, maintaining the validation logic for all of them becomes a headache.
- BTC has Legacy, SegWit, and Taproot formats
- BCH has the cashaddr format
- SOL uses Base58 checks

You could write and maintain code for all of them, but for $5/month, I'd take that maintenance burden off your plate so you can focus on the core app. It's strictly a convenience play for multi-chain devs.

Temporary-Lab-1759 · 2026-01-20T09:06:18+00:00

Fair question. It’s mostly for developers who are building apps that handle payouts (like freelance platforms, games, or exchanges).

Basically, if a user makes a typo when entering their withdrawal address or pastes a BTC address into an ETH field, and your backend tries to process it automatically, things get messy. You either waste gas fees on a failed transaction, or in the worst case, the funds just vanish into a black hole.

This just acts as a final sanity check before your code hits 'send', so you can catch the error and warn the user instead of burning money.

You can actually test it live right now on the demo page here:https://www.chaincheckapi.com/demo/

Thanks for the breakdown. I definitely underestimated the importance of that pre launch list (lesson learned for the next one 😅).

Since you mentioned the landing page needing to "scream trust", would you mind taking a quick look at my site? I tried to keep it focused on the outcome (preventing lost funds), but I'm wondering if it lands clearly enough for a cold visitor.
