Exactly USD.e Coin wallet

What is Exactly USD.e Coin (EXAUSDC.E)?

The awkward name says a lot about this token. EXAUSDC.E is the Exactly receipt for a deposit of USDC.e on Optimism, and USDC.e is the bridged dollar token that arrived there before Circle issued a native version on the same network. Two stablecoins, same three letters in the middle, different contracts.

So a holder is dealing with two lookalike problems at once. The exaToken is not a dollar token at all: it is a share of Exactly's variable rate pool, redeemable for USDC.e in an amount that grows with the interest borrowers pay, while the number of shares in the wallet stays put. And the USDC.e underneath it is not interchangeable with native USDC, even though wallets, and people, often shorten both to "USDC". Anything you swap or bridge afterwards should be checked against the contract the interface actually selected, not against the ticker.

Fees on Optimism are settled in ETH, so a position like this still needs a small amount of ETH sitting beside it before it can be redeemed or moved.

Supported networks in Tangem (1): Optimism. Tangem holds a separate balance per network and names the network a transfer is leaving on right on the confirmation screen, before the card is tapped to sign, which gives you one last moment to read what is actually being sent. With a token whose ticker resembles two other things, that pause before signing earns its keep, and it is a good reason to park the position here.
