Гаманець для Aptos

What is Aptos (APT)?

APT is the native coin of the Aptos blockchain, a proof-of-stake Layer 1 built by much of the team that originally designed Diem. Everything that runs on Aptos is written in the Move language, whose main design idea is that assets are typed resources that cannot be accidentally copied or dropped by a contract. For a holder this matters in one practical way: a balance on Aptos is a resource stored under your own account, not a number in a contract's ledger.

What is specific about holding APT

APT pays for every transaction on the network, so any transfer, swap or staking operation needs a small amount of APT in the same account. There is no separate gas coin to keep track of.

An Aptos address is a 32-byte hex string starting with 0x, which is longer than an Ethereum address. Sending APT to an address that has never been used creates the account on-chain automatically. Aptos also supports key rotation: the address stays the same even if the authentication key behind it changes, which is different from most chains where the address is simply the key.

The ticker APT appears on other networks as bridged or wrapped versions issued by bridge contracts. Those are not the same asset as the native coin, and a transfer of native APT only ever happens on the Aptos network itself. There is no rebase, no token account to open and no old and new contract to distinguish.

Supported networks in Tangem (1): Aptos.

Because an Aptos account is defined entirely by the key that controls it, the only thing that really needs protecting is that key. Tangem generates it inside the card's secure chip and never exports it; the backup is a second identical card rather than a written phrase. For a Layer 1 coin that most people hold in one account for a long time, that arrangement removes the weakest point without adding any daily effort.
