Security & custody model
How Simply.Exchange handles funds, keys, and risk — transparency by design.
Non-custodial trading
Spot orders are signed by your wallet. We match and settle without holding trading balances as a custodian.
Fiat and token sales
Regulated payment flows. Settlement to issuer treasury; project tokens sent on-chain with order ID linkage.
What we never store
Seed phrases, private keys, or card numbers (cards are entered only in the payment UI).
Infrastructure
Hosted API with signed webhooks, idempotent payouts, and an auditable order ledger.
