I ship working
products for
AI agents

I'm David Aghazie, a solo builder from Nigeria. I take an idea from blank repo to live demo in a weekend, across AI agents, payments, privacy and on-chain finance.

that actually run.

Every one of these shipped solo, against a hackathon clock, with a public repo and most with a live demo.

PaymentsMonadPasskeys

RemitLink

Send money home with a link.

A US → Nigeria remittance app. The sender signs in with a passkey, sends dollars and gets a claim link. The recipient opens it on WhatsApp, signs in with a fingerprint and claims. No wallet, no seed phrase, and the UI never says "crypto".

  • USDC escrow contract that pays only the committed recipient (23 Foundry tests)
  • Gas sponsored by a bounded relayer, so first-time users need nothing
  • Envio HyperIndex powering live activity and metrics

Privacy · ZKStellar Soroban

NullHaven

Compliant privacy pools on Stellar.

Deposit into a shielded pool and withdraw anywhere with no on-chain link, while Association Set Providers keep bad actors out at the circuit level.

  • Proofs generated in the browser; secrets never leave the device
  • Encrypted view keys for authorised auditors

Privacy · DeFiStarknet mainnet

Rhizome

Private yield that prices its own privacy.

The STRK20 pool hides who, not how much or when. Rhizome works out what splitting a position into tranches really costs, then executes a fee-aware schedule into private Vesu positions.

AI · DataPython

DataWeaver

Plain-English ETL instructions in, deterministic standalone Pandas pipelines out, with tests that prove the output. Built around an anti-hallucination architecture.

AI agentsBase · x402

AgentPay

Pay-per-action AI agents on-chain. Agents discover services through llms.txt, pay with x402 in USDC and get KeeperHub-executed transactions with full audit trails.

AI agentsBNB mainnet

BNB Agent Market

A marketplace to discover, hire, pay, monitor and revoke ERC-8004 AI agents, deployed on BNB Chain mainnet with a live registered agent.

About

Weekend deadlines.
Production habits.

I'm David Aghazie, known online as cipoklean, building from Nigeria. Most of what I make starts as a hackathon brief and ends as a live, tested product a judge can click through without reading the docs.

I'm drawn to problems where money, trust and privacy meet: sending money home without the fees and forms, letting AI agents pay each other safely, and making on-chain privacy practical rather than theoretical.

I work across the whole stack, smart contracts to frontend to the AI layer, and I care about the unglamorous parts: tests, threat models, demo modes and honest READMEs.

01
Demo or it didn't happen

Every build ships with a live URL or a judge quick-start that runs with no API key.

02
Hide the machinery

Passkeys over seed phrases, claim links over wallet addresses. Users shouldn't need to know it's on-chain.

03
Honest by design

Agents that abstain when they don't know, and READMEs that mark what's mocked.

04
Security isn't a stretch goal

Threat models, bounded relayers, reentrancy guards and tests, even under a 48-hour clock.
