Plain English
Wormhole is a generalized cross-chain messaging and bridging protocol launched in 2021, originally on Solana. Suffered a $325M hack in February 2022 — replenished by Jump Crypto. Now supports 30+ chains. W token launched in 2024. Underpins many cross-chain dApps.
How it actually works
Uses a guardian network (19 validators) to attest to cross-chain messages. Wormhole NTT (Native Token Transfers) lets projects mint native versions across chains rather than wrapped tokens. Wormhole Connect provides UI components for any dApp to integrate cross-chain functionality.
What it means for you
Wormhole is one of the largest cross-chain bridges by volume. The 2022 hack history weighs on the security calculus, though the post-hack restoration and security overhaul has reset perception. For HNW users, Stargate or Across are typically lower-risk alternatives for L2 transfers; Wormhole is more relevant for transfers involving Solana, Sui, or alt-L1s.
