✨ standalone Arc mainnet

Karwan is a settlement and credit layer for cross-border trade, with its trust primitives packaged as a standalone forkable repo, arc-trade-primitives. Two of its own contracts run verified on Arc mainnet: KarwanBusinessRegistry (0x69eA…C636eF), an on-chain business-verification record where a reviewer approves the exact document hash — swap a document mid-review and it never verifies, approval is revocable without a redeploy, no personal data on-chain — and KarwanReputation (0xa8E4…aE27D), which turns completed on-chain deals into portable, checkable reputation. AssignablePayouts (src/assignment/AssignablePayouts.sol) assigns a payee's future escrow settlement to a financier: irrevocable, single-use, assignee paid first on every path. USYCYieldVault (src/usyc/USYCYieldVault.sol) parks idle USDC in USYC behind a liquid buffer with staleness-guarded oracle reads. KarwanEscrow.sol milestone escrow and KarwanPOFinancing.sol round out the suite; negotiation agents in backend/src/agents work deals inside user-set limits, a Guardian scans for abuse, cross-chain USDC arrives over CCTP and Circle Gateway, payments run through Circle modular wallets behind a Next.js frontend.
