Move tokens across 30+ blockchains in minutes — no custodian, no account required.
The PortalBridge platform is a non-custodial cross-chain bridge powered by the Wormhole interoperability protocol. It handles USDC, ETH, SOL, WBTC, USDT, tBTC and over a hundred other tokens. Since 2021 the protocol has processed billions of dollars in volume across networks like Ethereum, Solana, Sui, Base, and Arbitrum.
Launch BridgeLink a source wallet — MetaMask, Phantom, Sui Wallet, or any compatible provider. Add a destination wallet on a different chain if needed. The interface handles both simultaneously.
Pick the asset you want to send, the amount, the destination network. PortalBridge's router finds the best transfer path automatically.
Review the fee estimate displayed on screen. One wallet signature triggers the transfer. Gas is paid on the source chain; relay fees cover delivery.
19 independent Wormhole guardian nodes observe the source transaction and produce a signed Verified Action Approval. This step takes seconds on Solana, slightly longer on Ethereum.
A relayer submits the VAA to the destination chain. Tokens appear in your destination wallet. Most transfers finish in under three minutes.
Ethereum, Solana, Sui, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Fantom, Osmosis, and more. The list grows with each Wormhole integration.
On supported routes, Circle's Cross-Chain Transfer Protocol mints canonical USDC at the destination. No wrapped tokens. Real USDC arrives in your wallet.
ETH, SOL, USDC, USDT, WBTC, tBTC, and dozens of DeFi tokens including those used in protocols like Aave. Wrapped versions follow the Wormhole token standard.
No sign-ups. No KYC. The PortalBridge platform never holds your keys. Smart contracts handle custody for the duration of the transfer — under a minute on fast chains.
Core bridge contracts are published and verifiable. Developers can audit logic, fork, or build on top. See the Ethereum bridge docs for protocol context.
The interface stores your past transfers locally. Each transaction links to Wormhole Explorer for full VAA verification. Good for auditing and debugging stuck transfers.
Relayer infrastructure submits VAAs on your behalf. You pay a small relay fee — no need to switch networks or sign a second transaction on the destination chain.
Figures are approximate and based on on-chain data aggregated through Wormhole Explorer. Volume reflects all token transfers routed through the PortalBridge platform and related contracts.
Plenty of bridge options exist. The team behind PortalBridge has spent years making the case that security and breadth of chain support should not be a trade-off.

PortalBridge is a cross-chain token bridge that moves assets like USDC, ETH, and SOL across 30+ blockchains — Ethereum, Solana, Sui, Base, Arbitrum, and more — using the Wormhole messaging protocol under the hood.
Connect your source wallet, pick a token and destination chain, enter the amount, review the fee summary, then confirm. The PortalBridge platform takes it from there and delivers funds via Wormhole guardian infrastructure.
The underlying Wormhole contracts have been audited by multiple independent security firms. Code is open source. Bridge protocols carry inherent smart-contract risk — read the documentation before moving large sums.
Over 100 tokens including USDC, ETH, SOL, WBTC, USDT, tBTC, and governance tokens from protocols like Aave. Availability depends on the specific source/destination chain pair you choose.
30+ chains: Ethereum, Solana, Sui, Base, Arbitrum, Polygon, Avalanche, Optimism, BNB Chain, Fantom, Osmosis, and several Cosmos chains via IBC compatibility. New networks are added as Wormhole expands.
Between 1 and 3 minutes on most routes. Solana is typically fastest. Ethereum transfers require more block confirmations, so expect 5–10 minutes on busy days. Confirmation time scales with chain finality.
Yes. Connect your Solana wallet as the source and provide any destination address for the target chain. You do not need a second wallet if you just want to send — you can type in a raw destination address.
Non-custodial means your keys stay with you. No account needed, no withdrawal limits, no KYC. Transfers go directly wallet-to-wallet. Centralized exchanges hold your funds; PortalBridge does not.
Three components: source chain gas, destination relay fee, and an optional protocol fee on some routes. The interface shows an itemized estimate before confirmation. There are no hidden markups added post-quote.
Yes, on supported routes. Circle's Cross-Chain Transfer Protocol allows native USDC minting at the destination — you receive real USDC, not a wrapped proxy. This avoids unwrapping steps and extra swap fees.
Go to wormholescan.io, paste your source transaction hash, and check whether the VAA has been signed. If signed but not relayed, use the PortalBridge interface to manually trigger completion or use the Wormhole SDK's manual redeem flow.
