Selected Projects
Payroll that arrives the moment work happens. Real-time cross-border payroll and remittances on Circle Arc — stream USDC to anyone in the world, settled per second, claimable anytime, and bridgeable home via Circle CCTP.
Walk. Capture. Own the map. A real-time GPS territory game on Solana — run to claim real land, collect VRF-dropped Guardian NFTs, and battle them over Bluetooth or online. Every capture settles gasless on a MagicBlock Ephemeral Rollup.
Private, agent-native prediction markets. Your position stays hidden with zero-knowledge proofs, stakes are confidential via encrypted ERC, and markets resolve from Chainlink oracles — AI agents trade from a single SKILL.md.
Private-by-default money. Hold and transfer value with balances and amounts encrypted on-chain via eERC — every operation verified by a zk-SNARK, with a rotatable auditor that keeps it compliance-ready. Private, not anonymous.
The credit card for the machine economy. When an autonomous agent hits an HTTP 402 paywall with an empty wallet, Fund402 fronts the micropayment from an on-chain vault, settles it, and records the loan and the agent's reputation — no human in the loop.
Pay in crypto, spend in AED. A tourist payment wallet for the UAE that lets visitors settle in local currency and reclaim VAT tax refunds instantly — zkLogin sign-in, decentralized receipt storage, and an atomic escrow payout split.
