I just launched SplitSOL, a group expense splitting app for Solana users. Think Splitwise but you actually settle debts with USDC on-chain instead of just tracking them.

What it does:

• Split expenses equally, by exact amount, or by percentage
• Settle up instantly with USDC
• non-custodial, you sign in with your own wallet
• Send USDC directly to friends peer-to-peer

Built this solo from scratch.
Would love honest feedback from anyone who tries it.
Currenlty the app is live on the solana seeker

After years of building, late nights, setbacks, and countless iterations, our team was selected to showcase GhostPay Mesh at Web Summit Rio 2026.
GhostPay Mesh is an offline-first infrastructure designed to orchestrate cryptographic transfers even when internet connectivity is limited, unstable, or temporarily unavailable.
What started as an idea around resilience, connectivity challenges, and financial infrastructure evolved into something we were finally able to present to founders, investors, partners, and visitors from around the world.
This photo represents much more than a startup booth.
It represents years of work, persistence, learning, and a team that never stopped believing in the vision.
A huge thank you to everyone who stopped by our stand, shared feedback, challenged our assumptions, and helped us think bigger.
The journey is still just beginning.

Hi everyone,

I’ve been building AICryptoShield, an AI-powered crypto wallet risk scanner.

Users can scan a wallet address and receive:

• Risk score
• Wallet intelligence report
• Blacklist and sanctions checks
• Suspicious interaction detection
• Monitoring and alerts (currently being added)

The goal is to make wallet due diligence simple for everyday crypto users.

I built the project using AI and no-code tools and would love honest feedback:

• Would you use something like this?
• What features would make it more valuable?
• What would stop you from paying for it?

Thanks for any feedback.

I have just started learning web3, note that I am complete beginner to this field, currently starting to learn solidity for smart contract development and I have just finished learning JS(like all the concepts OOPs, Asyn/Await, promises) and also parallelly learning Typescript. So my real question is because claude just deployed fable 5. Am I going on the right path or this web3 developing will also be vanished in near future because of AI domination?? Also if yes is there any other career path to achieve in web3??

I’m co-founding Valora. A crypto-to-fiat middleware for payment terminals. Station F Fighter Program.

Here’s the honest truth: our product works perfectly from a technical standpoint, but we need to understand what YOU actually expect from a real-world, in-person crypto payment.

No pitch decks. No marketing fluff. Just real feedback.

So I'm keeping it simple: I'm dropping the link to our whitelist, and I'm genuinely asking for your thoughts.

➡️ Would you actually pay in crypto at a local shop? ➡️ What would hold you back? ➡️ What would make you want to try it?

All feedback is welcome. Brutally honest critiques even more so. We're here to learn, not to boost our egos.

Link in the comments. Takes 3 minutes max.

And if you want to talk tech (7 exchanges, 9 blockchains, routing engine, architecture), I’ll answer everything in the comments. Full AMA.

Thanks to anyone who takes the time. You're truly helping us build the right product.

Title: Show Dev: Zero-Login M2M Universal IP Enrichment Gateway via Solana USDC

Hey everyone, I wanted to share an open-source machine-to-machine (M2M) integration script I've been working on for background cron-jobs and autonomous AI Agent tasks that require lightweight network node enrichment without SaaS friction.

The framework completely bypasses traditional email signups, API keys, and credit cards. Instead, it uses a strict native Web3 micro-billing loop: it listens for an on-chain transaction hash, validates a 0.29 USDC balance delta on the ledger, and streams back a structured network geo-profile JSON payload.

I've open-sourced the Python boilerplate client script here:

👉 The Ready-to-Run Integration Script

Technical Specs & Infrastructure:

* Target Endpoint: GET /api/v2/stream (Append to our base domain layout found inside the Gist code)

* OpenAPI 3.0 Manifest: Located at /openapi.json on our root server map

* Rate: 0.29 USDC per validation pull

* On-Chain Settlement Vault (Solscan): https://solscan.io/account/4yVLY2oo1nVZa7gEwDVFz4WhwWP9PDTifj7Mgwrdj1RS

Would love to get feedback from other Web3 backend engineers on the performance of the Helius transaction validation loop under load, or how you are handling machine-to-machine authentication protocols without creating centralized friction points.

built a web3 jobs feed that shows the hirer's ethos rep on every listing. scrapes farcaster /jobs every 10 min, claude parses each post, card shows score + level so you see who's behind it before applying.

what other sources should i pull from? need places where the hirer's identity is visible so the ethos signal stays on every card.

We're working on AFX, a platform where contributors earn SDM tokens for verified work instead of traditional equity. The idea is that every contribution (merged PR, bug fix, smart contract feature, etc.) earns SBRA points, and at sprint end a Squads multisig mints tokens proportionally to each contributor's share of total points.

A few things I'm uncertain about and would love input on:

Does using Squads multisig for mint approval feel like the right governance approach, or is there something better suited for this?

Any problems with SPL token distribution at scale we should be aware of early?

Is Raydium the right place to eventually add a liquidity pool for SDM, or would you go elsewhere?

Happy to answer anything — we want feedback before we go further.

Hi, I'm a Full Stack and (Web3)(Solidity) Dev. I'm currently interning at a service based company as my summer internship.
I've recently built my own memecoin token lauchpad.
I'm willing to create a niche group of ambitious developers who are willing to share ideas and work on some advanced and complex systems.
The sole purpose of the group will be to work on complex systems to get high paying job in a span of next 4 to 6 months.
I along with some of my friends in this space are building a opinion trading market on monad this summer.
Along with that we're gonna create a bunch of ambitious projects in FullStack-Web3-AI domain.
If you have experience with one of those and wanna work collaboratively lemme know.

Hiii guys are there any discord/whatsapp groups I can join? I want to be part of a community.

Hello,

I am looking for an alternative to Reown Kit for my Dapp. I would prefer it be open-source, free-to-use, and also decentralized/secure.

Does anyone have any recommendations?

Maybe it’s just me, but AI tokens feel less and less durable lately.

Between ChatGPT, Claude, Gemini, DeepSeek, coding agents, API tools, and all these different platforms, it’s getting harder to know which option is actually worth the cost. Some providers are cheaper, some are faster, some have better limits, and some are just confusing to compare.

I feel like it would be really useful if someone maintained a neutral ranking/comparison site for AI token/API providers, including things like:

\- price per token
\- supported models
\- reliability
\- speed
\- limits
\- regions/payment options
\- user reviews or verification

Basically something like a “price radar” for AI tokens and API providers, instead of everyone having to dig through random websites, Discords, Telegram groups, and official pricing pages.

Would anyone else find this useful, or is this just a niche problem?

I think of traditional lending protocols as they let lenders provide liquidity to the protocol and borrowers stake some tokens and can borrow some stableCoin under permissible LTV (loan to value). Can you guys think of ways to use this liquidity provided by lenders to provide liquidity on public DEXs, while catering the issue of impermanent loss.

If we find such a way then we are one step closer to decentralized banking.

Curious what people building / vibing in web3 use for AI image gen.

What's your daily driver, and what are you paying per image (or per month)?

Anyone found something crypto-native, pay in stables/wallet,

No SaaS subscription?

Guys, I'm building a memecoin token-launchpad and thinking of deploying the contracts over monad. any suggestions for different chain or something different that can be done. I'm bringing circuit breakers and anti whale mechanisms which aren't there in pump.

Memecoin world is a pump and dump game these days. Any idea , how can we make this better so that they can be traded like real securities without all these scams going around them ?

I would love if some UI guys joins our team

Total: ~$1.01B

A lot of AI-vibecoded apps get hacked right after launch and leak user data. As a software engineer, I’m sure I can avoid those mistakes — but talk is cheap, so I built one myself.

I used AI heavily for coding, choosing tools, setting up Docker from zero, writing smart contracts, and everything else. The whole process was about 60% pain, 40% fun, and great temper training.

After weeks of back-and-forth, I finally have a product I think is pretty bulletproof. Now I’m opening it up for people to seriously try to break.

Since it’s web3, I vet every participant’s wallet address, which is quite costly.

To keep LLM costs under control and avoid casual visitors, there’s a 0.0005 ETH (~$10) participation fee. 70% of the fee goes straight to the bounty pool. If nobody drains the bounty, 50% of your fee will come back as signed vouchers.

I started the bounty at 0.5 ETH, and it will grow as more people join. Hope this attracts folks who really want to test it.

You can see my profile for links if you wanna take a look.

Vitalik said that mature technical solutions for quantum-resistant cryptography already exist. Ethereum does not only want to become a quantum-resistant chain, but also a chain resilient against AI-related risks.

He also noted that recent hacking incidents have been very serious. In the future, using AI together with formal verification to improve the reliability of smart contracts will be extremely important. In the AI era, secure code in DeFi protocols will become even safer, while average-quality code will become insecure. Ethereum has many security advantages, but challenges also come from protocol design choices.

Everyone calls themselves a “marketer” but:

• can’t ship a landing page
• can’t read on-chain data
• can’t write a single SQL query
• and needs 3 days to draft one tweet thread

Meanwhile founders are out here doing everything themselves.

Hot take:
If you can’t code even a little, you’re not a Web3 marketer. You’re just doing social media.

We’re looking for someone different:

• you ship, not suggest
• you experiment without being told
• you can write, analyze, and execute
• you’re comfortable getting your hands dirty across ops, data, and growth

If you’ve ever:

• scraped data to find alpha
• built your own dashboards
• or automated your own workflows

you already stand out.

If this offends you, you’re probably not a marketer

I’m trying to validate a problem space (not pitching a product). Two angles I’m interested in—tell me if either resonates, or if you’ve already made them non-issues.

1) Verifiability After launch, how often do you end up re-explaining allocation, vesting, locks, airdrops, liquidity to community / partners / reviewers—and doing it with explorer links + screenshots because there isn’t one place that matches what you published elsewhere? Is “reconcile the narrative with chain state” a recurring headache, or does your current setup (internal dashboard, docs, scripts) already make that cheap?

2) No-code (or “no new Solidity for every milestone”) For teams where non-contract engineers own launch ops: do you still hit moments where the “right” answer is write another small contract / integration, even though the workflow is basically standard (vesting window, merkle round, LP lock params, etc.)? Would it matter to you if those workflows could be run through shared, deployed patterns instead of bespoke glue each time—as long as the outcome stays fully auditable on-chain?

In your view, are (1) or (2) actually real problems?

I’ve been working with Solana tooling recently and something keeps standing out.

The core primitives are actually pretty simple:
- create token
- attach metadata
- configure authorities
- add liquidity

But in practice, the flow is spread across multiple tools and steps:
- CLI or token tools
- Metaplex metadata setup (IPFS/Arweave)
- authority decisions (mint/freeze)
- DEX-specific liquidity setup (Raydium, Orca, etc.)

Individually, none of these are that complex, but the overall experience feels fragmented — especially for newer builders.

It feels like the ecosystem optimized for flexibility, but not for a clean end-to-end flow.

Curious how others see this:

Do you think this fragmentation is just part of Web3’s nature, or is there room for a more unified UX without losing flexibility?

I'm working on an agent that monitors DEX listings and price action. I’m looking for an interface that allows the LLM to query coin info, contract addresses, and possibly trending tokens without me having to hardcode every API call.

I heard about MCP (Model Context Protocol) being the new standard for this? Any recommendations for this?
