Portal Bridge

Portal Bridge

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 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 manages both at once.

2. Choose token and chain

Select the asset you wish to send, the amount, and the destination network. Portal Bridge's router identifies the optimal transfer path automatically.

3. Confirm and sign

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.

4. Wormhole signs the VAA

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.

5. Funds arrive

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

Key features

30+ supported networks

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

Native USDC via CCTP

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.

100+ token support

ETH, SOL, USDC, USDT, WBTC, tBTC, and many 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 Portal Bridge platform never holds your keys. Smart contracts manage custody for the duration of the transfer — under a minute on faster chains.

Open-source contracts

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.

Transaction history

The interface saves your past transfers locally. Each transaction links to Wormhole Explorer for complete VAA verification — useful for auditing and resolving stuck transfers.

Automatic relaying

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.

Why Portal Bridge

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.

FAQ

What is Portal Bridge?

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.

How do I bridge tokens on Portal Bridge?

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.

Is Portal Bridge safe and audited?

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.

What tokens can I bridge?

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.

Which blockchains does Portal Bridge 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 the quickest. Ethereum transfers require more block confirmations, so expect 5–10 minutes on busy days. Confirmation time scales with chain finality.

Can I use Portal Bridge 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 simply want to send — a raw destination address is sufficient.

Why should I use Portal Bridge over a centralized exchange?

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.

What fees does Portal Bridge charge?

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.

Does Portal Bridge support native USDC via CCTP?

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.
