What is renBTC (RENBTC)?
renBTC was the output of a bridge. Bitcoin went into custody held by RenVM, a network of nodes running the key management, and an equivalent token was minted on the destination chain at 1:1, so BTC exposure could be used inside Ethereum contracts and later burned to release the original coins back to a Bitcoin address.
That mint and burn path no longer operates. Ren's bridge was wound down following the collapse of the company funding its development, which means renBTC should not be treated as a redeemable BTC receipt any more. What remains on-chain are ordinary transferable tokens - an ERC-20 on Ethereum and equivalents on BNB Smart Chain and Polygon - that can still be moved and swapped wherever liquidity exists for them, without the original route back to Bitcoin behind them.
That also changes what the three chain versions mean. Each is its own contract and its own balance, and with the bridge gone they are not interchangeable by minting and burning; getting from one to another means finding a market or a third-party bridge, not calling the protocol. A renBTC balance on Polygon is simply not the same holding as one on Ethereum.
Supported networks in Tangem (3): Ethereum, BNB Smart Chain, Polygon POS. Each chain gets its own renBTC line in the app, and the network a transfer will go out on is named on the screen the card signs. Reading it is your job, not the wallet's: EVM addresses look identical across all three chains and nothing on your side can know which chain the receiving party is watching. Done that way, three parallel balances stay three legible things instead of one confusing one.
