What is Portal Bridge (Wormhole)?
Portal Bridge is the token transfer app for Wormhole, a message-passing protocol that connects EVM and non-EVM chains. Wormhole's contract list shows Core Contracts on 37 mainnet chains, and its security page counts 29 third-party audits by firms including Trail of Bits, OtterSec and Zellic.
How Portal Bridge (Wormhole) works
Wormhole's Wrapped Token Transfers (WTT) module, which the contracts and SDK call Token Bridge, moves standard tokens between chains.
When you send ETH from Ethereum to Solana, the WTT contract on Ethereum locks your ETH and calls the Wormhole Core Contract, which emits a message. Guardians watch the chain, and once 13 of the 19 sign, the message becomes a Verified Action Approval (VAA). The VAA is submitted to the WTT contract on Solana, which verifies it and mints wrapped ETH to you. Sending it back burns the wrapped token and releases the original.
Some tokens get better routes than a wrapped IOU. Native USDC can move over Circle's CCTP between CCTP-enabled chains, issuers that deploy Native Token Transfers keep ownership of their token on every chain, and ETH, wstETH and USDT have relayed routes that end in the canonical asset on chains such as Arbitrum, Base and Optimism. When a better route exists for your pair, the Connect widget shows only that route.
How to start with Portal Bridge (Wormhole)
- You need a self-custody wallet on the source chain and a receiving address on the destination chain.
- Pick the source chain, token and destination.
- On the automatic route, a relayer submits the second transaction for you for a small fee, so you sign once.
- On the manual route you sign twice: once to lock or burn on the source chain and once to redeem on the destination, which needs gas there.
- Complete a manual transfer within 24 hours.
- Guardian Sets are guaranteed valid only for that long, and a later redemption can be rejected if the set changed in between.
- You can look up any transfer on the Wormholescan explorer.
- Wrapped tokens keep their name, symbol and decimals, but only the WTT program controls them, so metadata fixes such as a token image on Solscan go through the Solscan team, not Wormhole.
Portal Bridge (Wormhole) fees and limits
- An automatic route adds a relay fee charged at cost on the destination chain, so the transfer must cover it: about 4.2 USDC to Ethereum L1 and 0.3 USDC to Base, Optimism, Arbitrum or Avalanche.
Neither the Portal Bridge terms nor Wormhole's Connect FAQ list a bridge or protocol fee; the terms make you responsible for the gas fees of any transaction you start. On a manual route you pay gas twice, on the source chain and again to redeem on the destination, and the FAQ says there is no minimum amount when you pay gas yourself. Gas dropoff lets the relayer swap part of the transferred amount into the destination chain's gas token.
Risks to know before using Portal Bridge (Wormhole)
- Wrapped tokens received through WTT are contracts deployed and controlled by the WTT program, backed 1:1 by assets locked on the source chain, so their value depends on that lock staying intact.
- Validity rests on the Guardian signatures: 13 of 19 validator companies must sign, and a two-thirds supermajority of Guardians can upgrade contracts or change the Guardian set through governance.
- On delegated chains, a smaller subset of Guardians does the direct observation before the canonical set signs, which the docs call a per-chain trust assumption.
- Two safeguards limit damage: the Global Accountant blocks transfers that would break total supply across chains, and the Governor delays suspicious outflows.
- The bug bounty runs on Immunefi.
