Prom wallet

What is Prom (PROM)?

PROM started life under the name Prometeus, and that older name still turns up in token lists and explorers next to the current one, Prom. Both refer to the same token with the same ticker, so a listing that says "Prometeus" is not a lookalike - it is this asset.

What the project does today is run Prom, a modular zkEVM Layer 2. The chain settles on a base network and posts its transaction proofs to other chains as well, EVM and non-EVM, so applications can talk across ecosystems instead of staying locked to one. PROM is the token that runs the network: it pays for execution on the Prom chain and is what the ecosystem's applications are built around.

For a holder the practical point is that PROM exists in more than one place. On Ethereum it is an ERC-20 and every transfer is paid in ETH; on BNB Smart Chain it is a BEP-20 and the fee is paid in BNB. These two are separate balances that move between chains through the project's bridge, and neither is the same thing as PROM sitting natively on the Prom L2 itself. Keep a little of the fee coin next to the token on whichever chain you use, or a transfer will simply not go out.

In Tangem the two versions appear as two independent lines, and when you send you choose which of them you are sending from. Since an EVM address looks identical on every chain, the network is your decision to make and check, not something a wallet can verify for you - a wrong pick becomes a bridge job to undo, so it is worth one glance before you tap the card. Supported networks in Tangem (2): Ethereum, BNB Smart Chain. Holding PROM on the chain you actually use, with its fee coin alongside, is the whole setup this token asks for, and Tangem covers it without extra steps.
