Bridge to Base

The orderbook settles on Base: cheapest gas, one combined book. Your wallet signs every transaction; funds never touch U.CASH.

From Polygon

No direct rail: two hops via Ethereum (burn, checkpoint claim, deposit). The wizard walks both.

Need USDC on Base?

Pairs quote in native USDC. USDC bridged via the canonical rail arrives as USDC.e, which is not listed here: use any-token routing instead.

Base to Ethereum withdrawals take ~7 days (OP challenge window). Plan inventory accordingly.
