AB (prev. Newton) wallet

What is AB (AB)?

AB carries the history of the Newton Project, and that history is the single most useful thing for a holder to understand. The ecosystem rebranded from Newton to AB, and the token people used to know under the older name and ticker became AB. Anyone holding from the Newton era, or reading older material, is looking at the same asset under a name it no longer uses. The direction of the project itself is a mainnet with industry-oriented sidechains and cross-chain links out to other ecosystems, with real-world asset use cases as the stated focus.

The second thing is that the BNB ecosystem has two different chains, and they are not interchangeable. Supported networks in Tangem (2): BNB Beacon Chain, BNB Smart Chain. The Smart Chain version is an ordinary EVM token at a 0x address with fees in BNB; the Beacon Chain version uses bnb1-style addresses and its own fee rules. Sending one to an address belonging to the other does not work, and no amount of confidence about the ticker changes that. Check the address format matches the balance you are spending from before signing.

Because this asset has already been through one rename and its ecosystem is still adding chains, the useful property of a Tangem card is that your key is generated in the card's secure element and stays there. Your address does not change when the branding does, and restoring on a spare card from the same set brings back the exact same addresses. Holding AB through whatever the ecosystem does next is therefore a matter of keeping the card, not of tracking announcements.
