Focused entry on the platform's 2-of-3 multisignature escrow contract: how it works, what it guarantees, what it does not.

Mechanics

Each order is locked in a 2-of-3 multisignature contract. Three keys exist: buyer, vendor, platform. Two signatures are required to authorise any movement. The contract address is publicly visible on-chain; the signatures themselves are not, but their effect on the contract state is.

What it guarantees

The platform alone cannot move funds. The vendor alone cannot move funds. The buyer alone cannot move funds. Any single-party failure (compromised key, malicious actor) does not put funds at risk so long as the other two parties are honest.

What it doesn't guarantee

The escrow does not protect against bad-faith vendor behaviour where the vendor has the buyer's release. The dispute panel exists for that case. The escrow also does not protect against buyer-side credential theft — an attacker who controls the buyer's account can co-sign a release. PGP-2FA is the structural mitigation for that vector.
