Гаманець для Exactly WBTC

What is Exactly WBTC (EXAWBTC)?

Three layers sit under this ticker. Bitcoin is held by WBTC's custodians, WBTC is the Ethereum-standard token representing it, and exaWBTC is what Exactly issues when that WBTC is supplied to its variable rate market on Optimism. Each layer has its own way of failing or being unwound, and unwinding runs strictly in reverse order.

A few things follow from that. The token inherits WBTC's eight decimal places instead of the eighteen most ERC20 balances use, so quantities are small numbers with a lot of meaning in the last digits and a mistyped amount is easy to make. The balance stays constant by design; what moves is the rate at which one exaWBTC converts back into WBTC as the market accrues. Withdrawing depends on the pool having WBTC free at that moment, since supplied bitcoin may be lent out against the protocol's borrowing side. And every action, including a plain transfer of the receipt token, needs ETH on Optimism for gas.

A supply position like this tends to outlast phones, laptops and interfaces. The key that controls it is created inside the card's secure element and stays there, an identical second card restores the same wallet if the first one disappears, and a recovery phrase is a choice you make rather than a step you must complete. Storage that asks nothing of you for a year at a time matches how this position is actually held.
