Vacuum.exchange

Vacuum.exchange is a no-account, no-KYC cryptocurrency exchange for crypto-to-crypto swaps. There is no sign-up, no identity check and — by design — no balances and no wallets: the service holds funds only for the few minutes an exchange takes, and there is no way to deposit without an order. It supports 23 assets across 11 networks (Bitcoin, Ethereum, Monero, Litecoin, Solana, Tron, Dogecoin, BNB, Polygon, Avalanche, Toncoin, plus USDT and USDC on the chains that carry them), any-to-any in either direction. How it works: you get a fixed rate and a fixed deadline, send your coins to a one-time deposit address, and Vacuum pays out to the address you named on the network you named. Every status change is pushed to a signed webhook with retries, and the rate is locked at order creation. Refund handling is unusually strict and honest: the refund destination is agreed once at order creation and is immutable afterwards — not changeable by any API call, callback or support request — which removes a common attack where a "refund" is steered to whoever asks later. Custody and what to weigh: despite the "no custody" framing, funds do pass through Vacuum during the swap, so it is custodial for that brief window — best for moving value, not for storage. It is a newer, privacy-focused service reachable over a Tor onion address; as with any custodial exchange, use a wallet you control for the payout and start with a modest amount until you are comfortable with it.
