On-chain escrow
USDC for every trade locks in an audited escrow contract on Base. The merchant cannot release until you confirm; you cannot reclaim until the timer expires.
Trade peer-to-peer.
Escrow on-chain.
Primeborg P2P matches buyers and sellers directly. USDC sits in an audited escrow contract until the fiat payment clears. Disputes are resolved by a mediator council.
What you get
5 things that distinguish Primeborg P2P
Multiple payment rails
Bank transfer, PayPal, Venmo, Zelle, Wise, Revolut, mobile money, and in-person cash meetings. Each merchant lists the methods they actually accept.
Merchant ranks
New / Verified / Trusted / Established / Legendary ranks reflect completion rate, dispute rate, and trade history. The data is on-chain so you can audit it yourself.
Mediator council disputes
Disputes are resolved by a council of human reviewers with multi-sig authority over the escrow. No single party — not Primeborg, not the merchant, not the buyer — can move funds alone.
Optional KYC for trust
Merchants can require buyer KYC. Buyers can prefer KYC-verified merchants. KYC documents are stored encrypted; only the mediator council can access them during a dispute.
Frequently asked
Honest answers, not marketing
How is P2P escrow different from a centralized exchange?
A centralized exchange custodies your funds and matches buyers to sellers as a market maker. Primeborg P2P puts your USDC in an on-chain escrow contract that neither side controls alone. The exchange is permissionless — anyone can list a trade — and the escrow is auditable on Basescan.
What payment methods are supported?
Whatever the merchant lists: bank transfer, PayPal, Venmo, Zelle, Wise, Revolut, mobile money (M-Pesa, MTN, etc.), or in-person cash. Primeborg does not process the fiat side; the merchant and buyer settle directly. The on-chain escrow only releases after both confirm.
What happens if the merchant disappears?
After the trade timer expires (set by the merchant, typically 15-60 minutes), you can open a dispute. The mediator council reviews evidence — bank statements, payment proofs, chat logs — and votes to release the escrow to whichever side has the better case.
Are P2P trades private?
On-chain, trades show as USDC transfers to/from escrow — the counterparty addresses are visible but not necessarily linked to your identity. Off-chain, the merchant sees the payment method details you used. KYC documents (if required by the merchant) are encrypted and only visible to the mediator council during a dispute.
How does Primeborg get paid?
A platform fee (~0.2%) is deducted from the escrow at release. Merchants pay a separate stake to operate. There are no listing fees and no spread; the price between buyer and seller is whatever they negotiate.
Is there a way to operate as a market-maker?
Yes — merchants list public trading links advertising amount, currency, price, and method. You can run a desk that takes both sides of the book. Liquidity merchants get a "Has Liquidity" badge.
