OneKey

OneKey is a crypto wallet with a built-in Swap & Bridge function that compares routes for exchanging assets and moving them between networks. It supports custom user operations, so the same interface is used for storing assets and for converting them.

How exchanges work

OneKey itself acts as a wallet and interface. The actual swap and bridge executions run through partner integrations, which means the quotes, fees and execution risk of a transaction depend on the partner route chosen by the user rather than on OneKey as a counterparty. This is the standard model for wallet-based exchange and differs from an exchange or a broker holding client balances.

What to clarify

The public profile does not state supported chains, fee levels, limits or the legal entity behind the product. A business considering OneKey for treasury movements should check which networks and partners are available, how routes are ranked, what slippage settings exist, and where responsibility sits if a partner transaction fails. As a wallet, it does not offer fiat on-ramps in the description given.
