PortalBridge

PortalBridge

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 Bridge

How it works

1. Connect your wallets

Link 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.

2. Choose token and chain

Pick the asset you want to send, the amount, the destination network. PortalBridge's router finds the best transfer path automatically.

3. Confirm and sign

Review the fee estimate displayed on screen. One wallet signature triggers the transfer. Gas is paid on the source chain; relay fees cover delivery.

4. Wormhole signs the VAA

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.

5. Funds arrive

A relayer submits the VAA to the destination chain. Tokens appear in your destination wallet. Most transfers finish in under three minutes.

Key features

30+ supported networks

Ethereum, Solana, Sui, Base, Arbitrum, Optimism, Polygon, Avalanche, BNB Chain, Fantom, Osmosis, and more. The list grows with each Wormhole integration.

Native USDC via CCTP

On supported routes, Circle's Cross-Chain Transfer Protocol mints canonical USDC at the destination. No wrapped tokens. Real USDC arrives in your wallet.

100+ token support

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.

Non-custodial by design

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.

Open-source contracts

Core bridge contracts are published and verifiable. Developers can audit logic, fork, or build on top. See the Ethereum bridge docs for protocol context.

Transaction history

The interface stores your past transfers locally. Each transaction links to Wormhole Explorer for full VAA verification. Good for auditing and debugging stuck transfers.

Automatic relaying

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.

Why PortalBridge

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.

FAQ

What is PortalBridge?

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.

How do I bridge tokens on PortalBridge?

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.

Is PortalBridge safe and audited?

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.

What tokens can I bridge?

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.

Which blockchains does PortalBridge support?

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.

How long does a transfer take?

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.

Can I use PortalBridge if I only have a Solana wallet?

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.

Why should I use PortalBridge over a centralized exchange?

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.

What fees does PortalBridge charge?

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.

Does PortalBridge support native USDC via CCTP?

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.

What should I do if my transfer is stuck?

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.
