PolyExhange is a custodial spot exchange: one wallet, live market rates, instant swaps between assets, and withdrawals that a person checks before the funds leave the platform.
We operate a custodial exchange: when you deposit, the asset is credited to a balance we hold on your behalf, priced against the live market. From there you can swap between any of the 19 listed assets at the posted rate, hold a position, or request a withdrawal to an external address. We don't run an order book or match your order against another user's — every swap fills instantly against the platform's own posted rate, the same way an exchange counter or a bank's FX desk would quote you a price and settle on the spot.
This is a deliberate trade-off. An order book gives you price discovery from other traders; a posted-rate exchange gives you a rate you can see before you commit and a fill you can't get slipped on. We think that trade-off suits an account meant for holding and moving value more than for high-frequency trading.
Three systems do the actual work behind the account:
Because this is a custodial model, your balance is a claim against the platform, not a key you hold yourself. That's a meaningful trade-off worth understanding: it buys you instant swaps and a recoverable account (no seed phrase to lose), at the cost of trusting us to safeguard and honor withdrawals. We take that trade seriously — every withdrawal is reviewed by hand precisely because an automated pipeline is the easiest thing for an attacker, or a mistake, to exploit.

VIP is a fee rank on trade and swap. It does not skip human review on withdrawals. The worker on this hostname can change it on an account. Signed-in, rank shows on Wallet. Schedule: Fees.
| VIP rank | You pay | How it is set |
|---|---|---|
| Standard | Full exchange fee | Default on signup |
| VIP | 25% of exchange fee | We set it — never from volume |
