To identify who handled a wallet swap, preserve three layers: where you requested the quote, which provider the interface selected, and what the signed transaction or order did. No single logo necessarily identifies all three.
Where interfaces expose the evidence
| Interface | Useful location |
|---|---|
| Phantom | Provider settings and Pricing details before confirmation |
| Uniswap web app | Order routing field and route-information icon |
| Trezor Suite | Matched provider, exchange type and Trade ID |
| OKX web | Portfolio, DEX orders and linked explorer records |
These locations are documented in Phantom settings, Uniswap’s screen guide, Trezor Suite and OKX’s web guide.
What onchain evidence can and cannot show
A token approval identifies permission to a spender. It is not proof of which application later generated a quote. A transaction target can identify a settlement contract while leaving the frontend origin ambiguous.
The 0x FAQ explicitly notes that onchain data alone does not uniquely identify every transaction as originating from its API: the settlement contract can also process non-API transactions. Avoid claiming more attribution than the evidence supports.
A useful record
Save the quote’s provider label, selected mode, timestamp and order reference together with the confirmed transaction. For cross-chain swaps, add the underlying bridge and destination record. A screenshot taken before approval can preserve details that the final portfolio history omits.
This record helps compare repeated trades and direct support requests to the right party. It also prevents a common fee mistake: assigning an interface’s fee to the wallet merely because that wallet displayed the signing prompt. Attribute each cost and action to the service that actually supplied it.
