Verified buyers consistently flag the multisig escrow as the platform's headline structural feature. What they say works and what they say is friction.
What works: Buyer, vendor, and platform each hold one key. Any two sign for movement. Reviewers explicitly cite this as the reason they trust the platform with payment in advance of delivery; the platform cannot unilaterally move funds, the vendor cannot move funds without buyer release, the buyer cannot move funds without vendor co-sign. Most reviewers report multisig settlements clearing in 30–90 minutes from buyer release to vendor wallet.
What's friction: the multisig signing round adds a small latency overhead vs single-sig escrow; sub-1-percent of reviewers in the verified corpus call this out as material. Vendors with high-volume settlement workflows are more sensitive than buyers; vendor-side reviews of the multisig contract are 4.4/5 against buyer-side 4.8/5.
