The Problem
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.
The Solution
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.
Why it Matters
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.
