Wrapped Aptos (Universal) wallet

What is Wrapped Aptos (Universal) (UAPT)?

Aptos runs on its own account model, its own address format and its own signature scheme, and none of that travels. uAPT is the workaround: an ERC-20 token on an EVM chain, issued against APT held one for one in custody, so that an APT sized position can move through EVM applications. Burning the token is what releases the underlying APT again.

That makes the ownership split clear. Real APT pays for its own transactions on Aptos; uAPT is an ordinary token on the chain where you hold it, and its transfers are paid for in that chain's gas coin, ETH. So the wallet needs two balances to function: the token you care about, and a modest amount of ETH kept aside for fees, approvals and the occasional swap. Run the ETH down to zero and the uAPT is immobile until you top it up.

One other point for anyone planning to move funds out: an address on Aptos looks nothing like an EVM address, and there is no path that sends this token to one. Exchanges and services that list APT usually mean the native coin, not this representation.

For the day to day of it, Tangem keeps the gas coin and the token in the same wallet and signs with a tap of the card against the phone, so a small approval costs you a second rather than a hunt for a cable. That is a practical fit for a token you will actually be moving rather than just parking.
