What is teleBTC (TELEBTC)?

teleBTC is Bitcoin in wrapped form: real BTC is locked on the Bitcoin chain and an equivalent amount of teleBTC is minted on a smart-contract network, so one unit is meant to stand for one bitcoin. The point of holding it is to use bitcoin value where Bitcoin's own chain cannot go - in contracts, pools and swaps on an EVM network.

That wrapping is the whole story of what a holder has to watch. teleBTC is not BTC and is not designed to be sent to a Bitcoin address; it moves as a token on the network it was minted on, and it is redeemed back into BTC by burning it through the bridge that issued it. Supported networks in Tangem (2): BNB Smart Chain, Polygon POS. The same eight decimals as bitcoin mean amounts look familiar, but a teleBTC balance on one chain is a separate balance from the same token on another - they are not one pooled holding, and a transfer goes out on one chain only. Fees are paid in that chain's native coin, BNB or POL, never in teleBTC itself, so keep a little of it alongside or a transfer will simply not go through. It is also worth keeping straight that wrapped bitcoin comes in many flavours with different issuers behind them; teleBTC is its own, with its own redemption path.

Since the same address string exists on every EVM chain, the network is the part a person gets wrong. Tangem keeps each network's balance separate and names the network on the screen it asks you to confirm, so you read which chain the transfer leaves on before tapping the card against the phone - useful discipline for a token that exists in more than one place under the same name.
