Why we're strong & independent
Why we're strong
Collateral-first · math-enforced · unstoppable
Buyer always locks price + 10%. Seller locks a deposit tier before a listing goes live. Both stakes sit in public escrow on Base & Ethereum — chat opens only after both locks. Release, end together, and exit alone need 2 of 3 signatures (buyer, seller, or ARBITER). The contract owner cannot drain locked funds. Rules are open Solidity — not policy PDFs. Funded deals settle on-chain even if this website disappears.
Independent infrastructure
Not ruled by any country · nothing to hand over
p2pzero.air is neutral peer-to-peer infrastructure — we are not buyer or seller in your deals. No headquarters, no user database, no KYC vault. We do not collaborate with governments or share profiles — there are no names, emails, or IDs stored to seize. Chat encrypts on XMTP in your browser; listings live on IPFS; money moves only through public smart contracts. Your wallet is your only identity.
Why every party is safe
Safe for everyone
Why buyers, sellers, and both sides should trust the system
Buyers
Your money stays locked until you co-sign
- You lock price + 10% — seller must lock deposit too before chat opens.
- Release needs 2 of 3 — you keep a veto unless ARBITER joins a valid dispute.
- On success you receive the product (digital or physical) — your lock pays the seller; the 7% buffer is your fee.
- End together, exit alone, fault, and stale outcomes are fixed in the contract, not negotiable by us.
- Verify every step in your wallet before you sign — we never touch your keys.
Sellers
Buyers lock real funds before you ship
- Listing goes live only after your deposit is on-chain.
- Buyer locks price + 10% before coordination — no empty promises.
- On success you get price + deposit back minus the 7% fee — math is in Solidity.
- Reputation tiers lower your deposit over time — earned on-chain, not by admin.
Both sides · neutral rules
Same rules · no favouritism · no master key
- ARBITER is a 3rd signature only — needs 2-of-3 with buyer or seller.
- Contract owner cannot drain escrow — rules are auditable on-chain.
- Chat is XMTP encrypted — we do not read or store your messages.
- Deals settle on Base & Ethereum even if this website goes offline.

Your deals
Every purchase and sale in one place. Mark delivery done, co-sign release with the buyer, or request the arbiter if something stalls.
Your funds are protected: Escrow is live on-chain before you deliver. Verify on BaseScan or Etherscan, then co-sign release — ARBITER 2-of-3 if needed.
Private chat
Talk to your buyer or seller after escrow locks. Share photos, video, or a meetup pin — messages encrypt on XMTP, not our database.

ARBITER
ARBITER dispute console — 2-of-3 settlement
