What is zkSync Bridged WBTC (zkSync) (WBTC)?

Two layers of packaging sit between this token and actual bitcoin. WBTC itself is an ERC-20 token backed 1:1 by bitcoin held by a custodian and minted or burned through approved merchants. This version adds a second layer: the original WBTC is locked in the zkSync bridge and a matching token is issued on the rollup.

For a holder that means redemption runs backwards through the same path. There is no way to turn this balance into bitcoin on the Bitcoin network directly from zkSync; it goes back across the bridge first, and only the original WBTC can enter the burn-and-release process. A practical detail: WBTC carries eight decimals rather than the eighteen most ERC-20 tokens use, so amounts look unusually short, and a balance like 0.0125 is a normal-sized holding rather than dust. Fees on zkSync are paid in ETH, which has to be on the rollup itself.

Supported networks in Tangem (1): zkSync.

One key in the Tangem card signs every transfer of this token on the rollup, with no import step and nothing to restore in between. Bitcoin exposure wrapped twice over is worth keeping under a key that never leaves hardware, and that is the case for holding this token in Tangem.
