Tempo Moderato assets
Tempo Moderato (eip155:42431) is Stripe’s test network for Tempo. These assets are used in Tempo-specific corridors.
Tempo has no native gas token. Transaction fees are paid in the USD-denominated tokenized currencies listed below — not a volatile native coin. If your fee token differs from the validator’s preferred token, Tempo’s Fee AMM converts it at a ~0.3% spread, and pathUSD generally has the best liquidity. This matters when you operate a settler, and when you do your initial Permit2 token approval; recipients never need gas of their own, and senders only need it for that one-time approval. See Tempo’s fee specification.
