Services / 02 / Solana & x402 builds
Solana apps for people who have never owned a wallet.
Onchain products where the chain stays out of the way: wallets created on the server, fees paid for the user, and x402 endpoints so AI agents can pay per request in USDC.
Tell me about your projectFree 30-minute intro call. Written scope and quote before any work starts.
Sound familiar?
If any of this is you, keep reading.
Your users drop off at 'connect wallet'.
You want AI agents to pay for your API per call, and card payments can't do that.
You have a hackathon prototype and need it to survive real users.
You need someone who has shipped on Solana, not someone who read the docs last week.
What you get
The deliverables.
- Solana programs and integrations: tokens, NFTs on Metaplex Core, payments
- Onboarding without a wallet app. The server creates the wallet and pays the fees
- x402 payment endpoints, so an agent pays in USDC and gets its answer in the same request
- The web or Android app people actually use, deployed and handed over
Proof
Things I've already shipped.
Superteam Balkan's representative for Macedonia. Organized the Solana Arena hackathon in Ohrid in April 2026.
Meet Everyone (Revoluchain)
Event Game / Onchain Rewards · 2026Badge game built for Revoluchain in Prilep. Tap someone's NFC badge or scan their QR and you've met, for both of you. Meet ten people and a non-transferable Metaplex Core card lands in a wallet the server creates for you, fees paid, no wallet app needed. Only the card goes onchain; who met whom stays off it.
Tally (Warm Vault)
Agent Commerce / Hardware Security · 2026Physical API key for the agent economy. Your bank card is the hardware wallet — every agent transaction requires an NFC tap, with the master seed split between an Android Keystore biometric shard and a card-derived shard that's never stored. Built for Colosseum Frontier 2026. Live at tally.lll.mk, with an x402 signal endpoint: an agent pays 0.1 USDC on-chain and gets the signal back.
Ainterview
AI EdTech · 2025AI-powered interview prep integrating x402 payment technology. Creates sustainable value for job seekers and employers within the AI economy.
SINFT
Social Impact · 2025Web3 platform empowering marginalized communities to fundraise via Social Impact NFTs. Bridging youth creativity with crypto-philanthropy.
How it works
From first call to handover.
- STEP_01
Intro call
30 minutes. You explain the problem, I tell you honestly whether I'm the right person for it.
- STEP_02
Written scope
What gets built, what doesn't, how long it takes and what it costs. In writing, before any work starts.
- STEP_03
Build in the open
You see working progress every week instead of a big reveal at the end.
- STEP_04
Handover
Source, files, documentation and a walkthrough. You own all of it.
After it ships: Mainnet finds problems devnet never did. After launch I can stay on for fixes, monitoring and the next feature.
QUESTIONS
Do my users need a crypto wallet?
Not unless you want them to have one. Meet Everyone gave every player a wallet created by the server, with fees paid, and nobody installed anything.
What is x402?
An open payment standard built on HTTP's 402 status code. An agent calls your API, gets a price, pays in USDC and gets the response. Tally's signal endpoint works this way at 0.1 USDC a call.
Devnet or mainnet?
Both. We build and test on devnet, then move to mainnet once the costs and the failure cases are understood.
Do you build the front end too?
Yes. The program, the backend and the app people tap on, from one person.
