AEVA

AEVA pays for gas — native transactions and EVM transactions alike — and is what validators stake. The fee market sets a base fee with a floor of 25 gwei (25·10⁹ aaeva per gas). Inflation is 0 on testnet-0.

aeUSD

aeUSD is the settlement coin: what trades are priced in and what income is distributed in by default. On a production network it is the display name of USDC bridged onto Aeva; the native aeusd on testnet-0 is a stand-in for it, handed out by the faucet.

Fees in aeUSD are refused on testnet-0: governance has a switch (fee.accept_aeusd) and it is off. A transaction that pays its fee in aeUSD fails with fee denom not accepted; an EVM transaction from an account that holds only aeUSD fails with a message saying gas is paid in AEVA.
