Routes

VOLT does not invent a price. CCTP moves USDC one for one, minus fees. Relay returns a live quote. If Relay has no quote, the button does not pretend there is a fill.

CCTP

Used when both chains have Circle USDC and you are paying in that USDC. Your wallet burns USDC with Circle’s TokenMessenger. Circle attests the burn. USDC is minted on the destination to the receiving address. Fast burn is used where that chain supports it. Arc uses standard finality.

The first time you bridge a token from a chain, the wallet must approve the messenger to spend the USDC. That approval is its own transaction. The burn is simulated only after that approval exists, so the first quote on a new token can still be signed.

Relay

Used for ETH, and for any route that touches Robinhood Chain. VOLT asks Relay for an exact-input quote, then has your wallet submit the steps Relay returns. Those steps can include an approval and a deposit. Each one is confirmed before the next is requested.

An ETH amount is not a USDC amount. 0.05 ETH is a price in the destination asset, not 0.05 USDC. The receive figure on the ticket is that quote. If the quote fails, you see no route instead of a copied number.

Polygon USDC stays on CCTP. It is not sent through Relay, including toward Robinhood.
