Curator Verdict & OpSec Breakdown

THE BOTTOM LINE

404.cash is a top-tier privacy tool delivering a verified zero-KYC posture, solid infrastructure, and proven reliability for the Monero ecosystem.

✓

Proven Strengths

▸ Anonymous account model: no real-name, phone, or government ID required to transact.
▸ Non-custodial architecture: user retains full custody of private keys throughout execution.

⚠

OpSec Trade-offs & Caveats

▸ Clearnet-only footprint: lacks an official .onion hidden service mirror; exposes visitor network IP unless routed through VPN/Tor.
▸ Fresh operational history: established recently (2026); limited track record under severe market volatility.

Review

Embeddable payment widget. Merchants get a public API key, drop an iframe into their checkout, accept XMR/BTC/LN/USDT. Optional managed routing settles to a single payout address. Used by stables.rip and others in this directory.

Fees

Per-tx fee 0.5-1% · BYOK or managed routing
