Send tokens across 30+ blockchains in minutes — no custodian, no account needed.
The Portal Bridge platform is a non-custodial cross-chain bridge powered by the Wormhole interoperability protocol. It supports USDC, ETH, SOL, WBTC, USDT, tBTC and over a hundred additional 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 manages both at once.
Select the asset you wish to send, the amount, and the destination network. Portal Bridge's router identifies the optimal transfer path automatically.
Review the fee estimate shown on screen. A single wallet signature initiates the transfer. Gas is paid on the source chain; relay fees cover the delivery.
19 independent Wormhole guardian nodes observe the source transaction and generate a signed Verified Action Approval. This step completes in seconds on Solana, and slightly longer on Ethereum.
A relayer submits the VAA to the destination chain. Tokens appear in your destination wallet. Most transfers wrap up in under three minutes.
Ethereum, Solana, Sui, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Fantom, Osmosis, and beyond. The list expands with each new Wormhole integration.
On eligible routes, Circle's Cross-Chain Transfer Protocol mints canonical USDC at the destination. No wrapped tokens. You receive genuine USDC directly in your wallet.
ETH, SOL, USDC, USDT, WBTC, tBTC, and many DeFi tokens including those used in protocols like Aave. Wrapped versions follow the Wormhole token standard.
No sign-ups. No KYC. The Portal Bridge platform never holds your keys. Smart contracts manage custody for the duration of the transfer — under a minute on faster chains.
Core bridge contracts are publicly available and verifiable. Developers can audit the logic, fork, or build on top. See the Ethereum bridge docs for protocol context.
The interface saves your past transfers locally. Each transaction links to Wormhole Explorer for complete VAA verification — useful for auditing and resolving stuck transfers.
Relayer infrastructure submits VAAs on your behalf. You pay a modest relay fee — no need to switch networks or sign a second transaction on the destination chain.
Figures are approximate and derived from on-chain data aggregated through Wormhole Explorer. Volume reflects all token transfers routed through the Portal Bridge platform and associated contracts.
Many bridge options exist. The team behind Portal Bridge has spent years demonstrating that strong security and broad chain support need not be a trade-off.

Portal Bridge is a cross-chain token bridge that transfers 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, choose a token and destination chain, enter the amount, review the fee summary, then confirm. The Portal Bridge platform handles the rest and delivers funds via Wormhole guardian infrastructure.
The underlying Wormhole contracts have been reviewed by multiple independent security firms. Code is open source. Bridge protocols carry inherent smart-contract risk — read the documentation before moving large amounts.
More than 100 tokens including USDC, ETH, SOL, WBTC, USDT, tBTC, and governance tokens from protocols like Aave. Availability depends on the specific source and destination chain pair you select.
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 the quickest. 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 simply want to send — a raw destination address is sufficient.
Non-custodial means your keys stay with you. No account required, no withdrawal limits, no KYC. Transfers go directly wallet-to-wallet. Centralized exchanges hold your funds; Portal Bridge does not.
Three components: source chain gas, destination relay fee, and an optional protocol fee on certain routes. The interface presents an itemized estimate before confirmation. No hidden markups are added after the quote.
Yes, on supported routes. Circle's Cross-Chain Transfer Protocol enables native USDC minting at the destination — you receive real USDC, not a wrapped proxy. This eliminates unwrapping steps and additional swap fees.
