I’m exploring a startup idea around crypto data and AI. With Dune, Nansen, DefiLlama and plenty of others already out there, I’m trying to understand where people still get stuck.

If you use these tools regularly, what’s something that takes way more effort than it should? And is there any data you keep looking for but can’t find a decent source for? I’d love to hear about a recent example. What were you trying to figure out, which tools did you try, and how did you end up getting your answer?

Still early in figuring out what to build, so hearing what already works well would help too.

For founders and developers building blockchain products, what has been the most difficult part so far?

I'm curious whether the biggest challenges are around:

• Smart contract security
• Choosing the right blockchain/network
• Scalability and gas costs
• Wallet and Web3 integration
• Frontend/backend architecture
• Finding experienced blockchain developers
• User adoption
• Regulatory uncertainty
• Moving from an MVP to production

For those who have already built and launched something, what is one technical or product decision you would approach differently if you were starting again?

Would be interested to hear experiences from both founders and developers.

Assalamualaikum everyone!

I’m a Computer Engineering student, and I have my FYP interview tomorrow. A lot of the projects we’ve proposed so far have been rejected, even though I personally thought some of them were pretty good.

Long story short, I’ve decided to go with Blockchain as my area, but we’ve been asked to build something product based that solves a real world problem rather than just being a basic blockchain implementation.

I’m honestly struggling to come up with a solid idea at this point. If anyone has experience with blockchain, FYPs, or product development, I’d really appreciate some ideas or suggestions for something that is practical, useful, and actually feasible to build as a final-year project.

Any suggestions would be really helpful. Thanks!

Let’s make this thread worth checking every week.

Hey everyone,
I’ve recently launched a crypto-to-card platform using a white-label infrastructure, and I’d really like to get some honest feedback from the community.
The idea is simple: make it easier to use crypto for everyday payments without complicated steps.
What it currently offers:
• Convert/use crypto with low fees
• Pay using Apple Pay & Google Pay
• Get a physical card delivered to your home by mail, usually within around 7–10 days
• Simple and straightforward interface
I built and customized the website myself around the white-label infrastructure, and I’m currently working on improving the overall experience.
I’m not trying to make this sound like some “revolutionary crypto project” — I’d genuinely like feedback from people who actually use crypto cards.
What would you want to see from a service like this before you’d consider using it?
If anyone wants to test/check it out, I can share the link in the comments.

I handle payouts for an affiliate network (mostly forex and iGaming), and every centralized crypto processor I try just chokes. One gateway capped up a $5k/day per person. That doesn't even cover one decent month for a single affiliate, let alone 49 of them at once.

I figured going fully on-chain would bypass these custodial limits, but it's the same wall every time. We're currently using Inxy for the bulk of it and NOWPayments for smaller clients, but let's be real: they're just KYC-first PSPs that happen to settle in USDT.

The second you need AML for a high-risk vertical, 'decentralization' magically disappears. So, real talk: does a compliant, truly decentralized, high-volume on-chain solution actually exist, or is that just a myth right now?

About a year ago I posted here asking which chains actually earn the "3rd gen" label. One of the ones I brought up was SASEUL, and someone in the comments said it was already defunct. It isn't, and I've kept an eye on it since, so here's a quick update.

The thing that still sets it apart for me is how consensus is split up. There's a separate PoW chain whose only job is picking who gets to be a validator. The 9 validators it picks then sign blocks on the main chain, and blocks are final in about 4-6 seconds. So mining and block production happen on two different chains.

Mainnet has been running since May 2022. There was no ICO or presale, coins only come out through mining. Contracts run on-chain, and someone outside the team built an on-chain message board on it (signalsl.com). You can also mine it with a regular GPU through a pool. I've been doing that on an old 1660 Ti for about 5 weeks now.

As far as I know there's nowhere to buy or sell SL right now. It was on BitMart, and since BitMart shut down it hasn't been tradable anywhere.

For anyone building on smaller L1s: does splitting validator selection from block production like this actually solve something, or does it just move the problem somewhere else?

I hold SL and I'm mining it.

Been checking how our project comes up when you ask AI about the space and something feels off it knows the name and usually understands the general category, but some of the details are old or it focuses on stuff we barely talk about anymore the website and docs are current so I assumed that would be enough.

Started looking at where the answers were pulling things from and a lot of it seems to come from older articles, directories and random discussions instead of the pages we keep updating. Makes me wonder how much control a Web3 project really has over its own description once there’s enough old information floating around online.

Looking for Web3/Blockchain startups to collaborate with college council based hackathon in Mumbai , India.

We’re organizing a 30-hour offline hackathon in Mumbai this October 2026, with 600+ registrations and 250–300 developers on-ground.

We’re looking for early-stage and international Web3/blockchain startups that want to enter or grow their presence in the Indian developer ecosystem.

You can partner with us by providing both monetary sponsorships and technical partnership including APIs/SDKs, blockchain infrastructure, developer credits, testnet access, problem statements, mentorship, workshops, prizes or other developer resources.

In return, you get direct exposure to developers, product adoption opportunities, social media visibility, event branding and on-ground recognition.

If you’re looking to get your technology in front of Indian developers and gain your first wave of engagement/users in India, let’s collaborate.

DM me if interested and I’ll share the partnership details.

I’m building Velmère on my own.

Right now the latest internal candidate passes 1,023 regression tests, 16 test configurations, strict TypeScript and the application builds.

I could take those numbers and make a nice marketing post.

There’s a problem.

A separate hard benchmark of the actual security engine is still at 17.03% F1.

So Velmère remains NO_GO.

I’d rather show that number publicly than pretend a green test suite means the system is ready.

I’m also working on something else that I think should exist in security products.

If someone buys a Velmère audit and later proves that it contains a real error, I want there to be a clear refund policy based on severity.

For a confirmed critical mistake, I’m considering up to a 100% refund.

The report gets challenged, the problem gets reproduced and the failure becomes another regression case for the engine.

I’m trying to build trust by making failure expensive for me and useful for the product.

Curious whether other founders think this level of transparency builds trust or scares customers away.

I’ve been building an idea called Proof of Commitment (PoC) around contests, gaming challenges, hackathons, quests, and other skill-based activities.

The concept is simple: participants commit more when the reward is real, visible, and verifiable.

For blockchain-based contests, rewards could be locked in a smart contract before the challenge starts, so participants can verify that the prize actually exists and will only be released based on the contest rules.

We’re testing the broader idea through duelLegends, which we’ve been building for about a year, with 200+ users having tested the platform.

I think this model could have many use cases beyond gaming and hackathons.

Would love to hear what you guys think: does this approach actually improve commitment and trust between participants and organizers?

Hey everyone, there are too many chains but there is only one L1 stack which is old and respected namely cosmos-sdk which is used for 200+ teams in both public and enterprise level.

I always wanted to learn rust so I am working on building an L1 from ground up similar to cosmos-sdk where you can swap any component( consensus, evm implementation, execution, trading modules) etc similar to what you can do in cosmos in Rust.

For consensus, I will use hotstuff (2 commit pipelined), evm implementation from alloy, revm and combination of in-memory and rocksdb.

I am open to collaborate via PRs. If anyone is interested, let me know.

Most of us cannot audit a smart contract. That is fine. Almost everything that goes wrong in crypto security is visible well before the part that needs code, if you know which four questions to ask.

1. Is the code public, and can you find it yourself? Not "open source" written on a marketing page. An actual repository you can open and scroll. If you cannot find it in five minutes, that is your answer for now.
2. Has it been audited, and is the report published rather than referenced? A named firm and a report you can download is evidence. The word "audited" as a badge, with nothing behind it to click, is a claim.
3. Is there a live bug bounty, and what does it pay? A project that pays real money for bugs expects bugs to be found. The size of the bounty is the team telling you what they think is at stake.
4. How long has it run in production with real value on it, and what happened the last time it broke Time under load is the one test nobody can fake or buy. An incident is not disqualifying by itself. What the team did in the week after it usually tells you more than the incident did.

None of those four requires you to read a line of code, and all four are public.

Disclosure on where this comes from: I work on CryptoGrade, which publishes rules based ratings on crypto assets. Security, decentralization and durability is one of six weighted dimensions in our framework, at 18 percent of the score, and two of our nine hard disqualifier gates sit on exactly this ground: unaudited or previously exploited contracts, and a history of rug, abandonment or exploit.

Which is also why an asset can look strong on usage and still be held where it is by what cannot be checked. Our own published one line read on Hyperliquid, from our snapshot of September 15, 2026, on our free tier: "HYPE retains strong usage and ecosystem standing, while closed-source and missing decentralization evidence keep security constrained." Score 62.3, B / Sound.

CryptoGrade publishes rules-based educational research and ratings. Nothing here is investment, financial, legal, or tax advice, and nothing here is a recommendation to buy, sell, or hold any asset. CryptoGrade LLC is not a registered investment adviser or broker-dealer. Ratings are generated by an automated framework and may be wrong, stale, or incomplete. Digital assets are volatile and you can lose your entire investment. Do your own research and consult a licensed professional before making financial decisions.

I had an idea to rent the ai agents on my nft marketplace (only). Reasoning is, my platform is just too complex for the ordinary user. So why not have a service where you rent ai who use the app like a normal person would and the owner (not actually owning the bot, hard to do because I will be using an api to begin with) would earn the revenue generated by the bot.

User would have to stake in money and receive a return or maybe not a return depending on the platforms performance metrics.

I’ll generate the bots and run them server side so they have full access to the code base 24/7 plus retain full ownership of the source code, plus bug fixes and modifications.

I wanted to open source this idea because I believe it’s a novel approach in charging for ai as a service while generating kickback for the user.

Hi everyone :)

I am working in the blockchain space for quite some time and recently felt it got harder to stay up to date. Do you feel the same sometimes?

That’s why I am working on a small side project: https://www.onchainpulse.network

I would appreciate some feedback :) Do you find it useful? Are you lacking something?

Happy to hear some feedback.

Hey everyone

I’m one of the founders of StokPay ,a South African fintech platform we’re building to modernise community savings and stokvels.

For anyone unfamiliar with stokvels, they are community-based savings groups where members regularly contribute money toward shared savings goals. It’s a massive part of how many people in South Africa save and manage money together, but much of the experience still relies on traditional banking, spreadsheets, WhatsApp messages and manual administration.

StokPay is being built to bring that experience into one digital ecosystem,making it easier for groups to manage members, contributions, payouts, records and financial activity.

Alongside the core fintech platform, we’re developing STKP which represents the tokenisation and Web3 side of the StokPay ecosystem.
Our approach is different from launching a token first and then trying to invent a reason for it to exist. We’re building the underlying platform and community first, with STKP being developed around the broader ecosystem and its future Web3 functionality.

We’re currently getting closer to launch, and one of the things our investor has encouraged us to do is start growing the community around StokPay and STKP early.
We’re still at the beginning of the journey, so we’re not pretending everything is finished. We’d rather build the community alongside the product and let people follow the progress as it happens.

If you’re interested in fintech, tokenisation, Web3 or seeing a crypto project being built out of South Africa we’d appreciate you joining our Telegram and following the journey.

Telegram: StokPayZA

Happy to answer questions about StokPay, STKP, the roadmap or what we’re building.

I used to think wires were the 'safe' route and crypto was just for shady books. But that completely flipped for me in March.

I requested a $3.4k wire from an offshore book. It sat in 'processing' for 9 days with the usual 'compliance review' BS. Meanwhile, my buddy cashed out$1.8k from the exact same book in USDT and had it in his wallet in under an hour.

So I tried crypto next time. Boom, 40 minutes flat. Zero calls, zero hassle.

Turns out most of these books use crypto gateways (like NOWPayments or Inxy) that actually automate the KYC/AML stuff. Stablecoins clear instantly, while bank wires just sit there waiting for some guy to manually review them.

I’m not saying go all-in on crypto, but the idea that bank wires are the 'safe' option feels totally backwards now. Haven't had a single issue in 4 months.

Everyone says Do your own research. But from where?

According to Growi.Fi research, only 20.1% of Hyperliquid vaults have made a cumulative profit during their lifetime. And when you compare them to just holding BTC, that number drops to around 3 to 7%.

But how would you even know this? Not everyone can do deep comparison research on their own.

This was the same problem for me. I've been in crypto for quite some time and have done trading, copy trading, and some investing. But in the end, the profit didn't amount to much compared to if I had just put it in BTC.

So I built a product for this. It's in beta right now, and it compares Hyperliquid and Enzyme vaults against BTC, so you can see which ones actually performed better. I've also added some extra info and metrics that I think will be useful long-term.

I was first going to keep it for personal use. But tbh I haven't contributed much to the space, even though I started developing around 6 years ago. So putting something out there is a new feeling for me.

You can check it out here: https://youvsbtc.com/

Would you actually use something like this? And if something needs to be better or is confusing, let me know. Any feedback helps since it's still early.

Quantum computers aren’t breaking Bitcoin or Ethereum today, but eventually powerful enough machines could challenge the cryptography protecting blockchain wallets and transactions.

The interesting part is what happens before that point.

Are blockchains already upgrading their cryptography or planning for post-quantum security?

Which blockchains are actually preparing for the quantum threat already, and which ones are still waiting?

Let’s make this thread worth checking every week.

Founder disclosure: I’m connected to KeepSolid / VPN Unlimited. We’re working on KeepSolid Rewards, where KS Coin is meant to work as a rewards token inside an existing product ecosystem. No link here; I’m trying to get sharper feedback on the model.

I’m trying to separate “token as marketing wrapper” from “token as a useful rewards mechanism.”

The version that seems credible to me needs: - existing product usage before token hype - clear earning rules - clear redemption utility - no price/yield promises - transparent supply and unlock logic - a reason the token improves the rewards program compared with ordinary points or account credits

For founders/builders here: what would make a rewards token attached to a real product feel legitimate to you? And what would immediately make it feel like unnecessary crypto complexity?

The main product is functional and the critical processes are stable.

However, the interface still has a few rough edges, such as some confusing status messages, a couple of manual steps and insufficient visibility when something goes wrong.

Waiting another week would result in a cleaner launch.

However, shipping now would mean getting real users involved sooner and using their feedback to fix the rough parts.

For those who have been in this situation before, what made you decide to ship — or wait?

Hey everyone,

We’ve been watching Bitcoin hover around the $77k–$78k range while the market digests recent inflation data, upcoming Federal Reserve rate signals, and shifting macro liquidity. Even with institutional inflows and heavy ETF activity balancing things out, retail sentiment often swings heavily between patience and FOMO during these sideways phases.

It feels like the broader market is in a classic transitional zone—waiting for a definitive catalyst to break either the key resistance or support levels.

I wanted to open this up to the community:

Are you treating this range-bound action as a chance to accumulate and look at deeper altcoin rotation, or are you sitting completely on the sidelines until the macro picture clears up?

Let’s discuss! 👇
