What is Re7 cbBTC (RE7CBBTC)?

Holding RE7CBBTC means holding a share in a curated lending vault rather than bitcoin itself. The deposit asset is cbBTC, a bitcoin-backed ERC-20 on Ethereum, which is already one step away from coins on the Bitcoin network; the vault token is a second step. Re7 Labs acts as the curator, deciding which lending markets the deposited cbBTC is allocated to and on what risk terms.

The practical consequence for a holder is that the number of tokens in the wallet does not move on its own. A vault share of this kind tracks value per share, so the redemption ratio against cbBTC changes while the token count stays where it is. A flat balance is not a sign that nothing is happening. Exit runs through the vault, converting shares back into cbBTC, and that cbBTC is what would then be moved or unwrapped further; each of those steps is an Ethereum transaction paid in ETH, so ETH belongs in the same wallet.

There is nothing to sign day to day. Tangem reads the share balance and its current value straight from the contract, while the key that could move those shares stays inside the card's secure element. A position you check rarely is well matched to a card you touch rarely.
