Direct answer: no. The reasoning, with on-chain and editorial evidence.
Nexus Market does not present scam-pattern indicators. The architectural test for an exit-scam-prone marketplace is whether the platform alone can move buyer funds; mandatory 2-of-3 multisig escrow means it cannot. The behavioural test is the “send to fresh address” ask — a known precursor to exit scams; Nexus has not issued any such request in two years of operation. The on-chain test is fresh-address funding patterns; on-chain telemetry shows no such patterns through the current quarter.
Scam concerns about the platform are typically rooted in confusion between Nexus and unrelated phishing clones that share the name. Always cross-reference the URL against the homepage masthead and verify the PGP timestamp signature before submitting credentials. The clone is the scam; the real platform is not.
