Understanding Blockchain Bridging
Blockchain bridging enables the transfer of tokens between incompatible networks by "wrapping" them into derivative tokens compatible with the target chain. The SUI ecosystem supports seamless token movement both to and from other blockchains through two primary solutions:
Key Bridging Solutions for SUI
- Wormhole Connect
An integrated bridge supporting assets from any Wormhole-compatible chain to SUI, featuring gas fee optimizations. - Wormhole Portal Bridge
A universal bridge powered by Wormhole, facilitating transfers across 22 supported networks.
Wormhole Connect: Features and Functionality
Asset Support
Initially supports major cryptocurrencies including:
- Ethereum: ETH, WETH, USDC
- Polygon: MATIC, WMATIC
- BSC: BNB, WBNB
- Avalanche: AVAX, WAVAX
- Plus 10+ other chains (Full token list)

Automated Gas Relay
- Single-Chain Fee Payment: Users only pay gas fees on the source chain (EVM/Sui).
- Target Chain Coverage: Relay services cover destination network fees.
Gas Drop-Off Option
- Users can prepay fees in source-chain tokens to receive native SUI for future transactions.
- Currently available for EVM-to-Sui transfers.
Developer Tip: Embed Connect Token Bridge directly into dApps using Wormhole's SDK.
Wormhole Portal Bridge: Universal Asset Transfers
Supports any asset across Wormhole's 22-chain network, including:
- Ethereum
- Solana
- Aptos
- Full network list

FAQ: SUI Bridging Essentials
Q: How long do cross-chain transfers take?
A: Typically 5-15 minutes, depending on network congestion.
Q: Are there minimum transfer amounts?
A: Yes, varies by asset. Wormhole displays minimums during transaction setup.
Q: Can I bridge NFTs to SUI?
A: Currently supported only through third-party NFT bridges.
Q: What's the cost difference between Connect and Portal?
A: Connect offers gas optimizations, while Portal provides broader asset support.
Q: How do I verify token authenticity?
A: Always cross-check contract addresses against the official list above.
Pro Tip: For high-value transfers, test with small amounts first. All SUI bridges undergo regular security audits, but caution is recommended when handling novel assets. 👉 Learn secure bridging practices
