Portal is the canonical token bridge built on Wormhole. It locks assets on a source chain and mints wrapped representations on 30+ destination chains using a 13-of-19 Guardian super-majority attestation.
Portal locks the source asset and only mints the wrapped token once a 13-of-19 Guardian super-majority signs the VAA.
0x3ee18B…8a585Each Guardian observes the lock and co-signs the VAA. A 13-of-19 super-majority is required before the destination chain will accept it.
Security still rests on the honesty and liveness of the Guardian set: if 13+ keys collude or are compromised, unbacked mints become possible — the very class of failure behind the 2022 $326M Solana exploit (since fully reimbursed). There is no on-chain timelock on upgrade VAAs.

Most blockchains are isolated. Moving assets — especially between EVM and non-EVM ecosystems like Solana, Sui and Cosmos — requires trusted intermediaries, slow wrapping flows, and per-chain bespoke integrations.
Portal locks assets on a source chain and mints wrapped representations on the destination chain after a 13-of-19 Guardian super-majority signs a VAA attesting to the lock event. The same Guardian-VAA primitive supports generic message passing, NTT, and governance.
Broadest chain coverage of any major bridge (30+ chains spanning EVM and non-EVM), 4+ years live, the largest bridge bug bounty ($1M Immunefi), and 29+ third-party audits including Trail of Bits, Cantina, Zellic and Sherlock.
