Universal BTC wallet

What is Universal BTC (UNIBTC)?

uniBTC comes from Bedrock and exists for people who hold wrapped bitcoin rather than native BTC. Wrapped forms such as WBTC or BTCB cannot be staked through Babylon directly, so Bedrock takes the wrapped token, routes the position into Babylon's bitcoin staking design, and issues uniBTC as the liquid receipt for it. Redeeming returns the underlying wrapped token, and the exit runs through the protocol's own process rather than a simple burn.

The defining complication is how widely it is deployed. uniBTC exists on a long list of chains, and each deployment is a separate contract with its own supply and its own liquidity. They are not one pooled balance. Moving uniBTC between chains means using a bridge route the protocol supports, and redemption generally has to happen where the position was opened, against the wrapped BTC that chain actually holds. Fees are paid in whatever the local chain uses for gas - ether, BNB, SOL and so on depending on where your uniBTC sits - so each chain needs its own small reserve.

Also worth knowing: the token count does not grow. uniBTC does not rebase, so a static balance is the expected state, not a sign something is stuck.

Supported networks in Tangem (11): Ethereum, Base, Arbitrum One, Optimism, BNB Smart Chain, Solana, HyperEVM, X Layer, Mantle, Rootstock RSK, Ink.

Tangem keeps a separate balance for uniBTC on each of those chains and states the network on the transaction you are about to approve. Read that line before you tap - an EVM address looks identical everywhere, and only you know which chain the other side is watching. For an asset scattered across this many deployments, seeing them listed apart is what keeps the picture straight.
