Summary

Wrapped BTC (Portal) — also labeled "Wrapped BTC (Wormhole)" on some platforms — is a Solana SPL token at mint address 3NZ9JMVBmGAqocybic2c7LQCJScmgsAZ6vQqTDzcqmJh representing Bitcoin value bridged onto Solana via the Wormhole/Portal token bridge. It is a long-established, verified, widely held asset (reported holder counts over 100,000 and a market capitalization in the hundreds of millions of dollars), but as a multi-layer bridged and wrapped asset it carries inherent custodial and smart-contract risks, including exposure to the 2022 Wormhole bridge hack, that are distinct from holding native Bitcoin.
