Launched in mainnet in early 2023, the Sui blockchain has grown rapidly in a short time. Sui’s node infrastructure is already established to support developer activities. Users who already hold assets on other chains also don’t need to start fresh. They can bridge their existing tokens to Sui and immediately begin interacting with its ecosystem.
Here is our list of the best Sui bridges supporting USDC to Sui, ETH to Sui, SOL to Sui transfers, and more.

Basics of bridging to SUI
In 2024, Sui’s DeFi ecosystem saw incredible success, with the Total Value Locked (TVL) increasing by over 700%, reaching $1.8 billion.

Cross-chain bridges make it simple to move assets from other blockchains to Sui. They reduce barriers for users to explore Sui’s growing DeFi ecosystem and participate.
What is a SUI bridge?
Sui bridge is a system that allows the secure transfer of assets, data, or value between the Sui blockchain and other blockchain networks.
Cross-chain bridges make it easy to move assets like ETH, USDC, or SOL from their native blockchains – Ethereum, Solana, etc. – to Sui or transfer assets back from Sui to their other networks.
Why use a SUI bridge for cross-chain transactions?
Imagine you hold USDC on Ethereum and want to use it to participate in a yield farming opportunity on Sui’s DeFi platform. Instead of selling USDC on Ethereum and rebuying it on Sui, you can use a Sui USDC bridge and avoid trading fees for multiple trades.
This is typically faster and more cost-effective than using DEXs or other intermediaries (especially bridging ETH to Sui) and more user-friendly compared to atomic swaps.
Many protocols also incentivize users to bring liquidity to new chains by offering rewards like reduced fees or airdrops.
How to bridge to SUI
With modern bridge solutions, users can perform cross-chain transactions in minutes or even in seconds if we think of Solana to Sui or Sui to Solana bridges.
Steps to bridge to SUI network
Let’s break down the typical bridging process step-by-step:
- Ensure you have wallets for both the source chain and the SUI blockchain (e.g. Sui Wallet or Suiet).
- Research a reliable bridge service supporting the assets you need.
- Link your wallets to the bridge interface (e.g. MetaMask for Ethereum and Sui Wallet).
- Select the asset to bridge (e.g. ETH to Sui) and confirm.
Some bridges offer automated claims to finalize the process in one transaction.
Top 5 bridges on SUI
Let’s explore the best bridges that support asset transfers to and from the SUI blockchain.
| # | Bridge | Supported Chains | Native USDC Transfer | Bridging Time |
|---|---|---|---|---|
| 1 | Sui Bridge | Ethereum | Yes | ~ 13 minutes |
| 2 | Portal Bridge | Ethereum, Solana, BNB Chain, Polygon, Avalanche, Arbitrum, Optimism, Fantom, Aptos, Kaia, Moonbeam | Yes | ~ 19 minutes |
| 3 | Nitro by Router | 30+ chains, including Ethereum and Solana | Yes | ~ 30 seconds |
| 4 | Suilend | Ethereum, Solana | No | ~ 16 minutes |
| 5 | Cetus | Ethereum, Solana | Yes | ~ 19 minutes |
Since Sui is in its active growth phase, additional chains, tokens, and features may be added to these bridges over time.
1. Sui Bridge
Website: https://bridge.sui.io/
Overview: A native bridge of the network, operational since September 2024. Purpose-built for the Sui blockchain.
Source: Sui Bridge
Supported assets: USDC, ETH, and WETH bridge between Ethereum and Sui.
Advantages:
- No bridging fees on SUI: gas subsidies for claiming tokens;
- One-transaction bridging;
- Native USDC transfers via Circle’s Cross-Chain Transfer Protocol (CCTP) from and to Solana and EVM networks;
- Supports a native representation of ETH on the Sui network;
- Secured by Sui’s native validator infrastructure.
Limitations:
- Limited asset support; currently focuses on Ethereum-based tokens.
The Sui Testnet Bridge version supports a larger pool of assets.
2. Portal Bridge
Website: https://portalbridge.com/
Overview: A token bridging application powered by Wormhole, a widely adopted interoperability protocol.
Source: Portal Token Bridge
Supported assets: Native and wormhole-wrapped assets across Ethereum, Solana, BNB, Chain, Aptos, and 6 more chains.
Key features:
- Native USDC bridging;
- Automatic claim: Gas fees are charged on the source chain (doesn’t apply to native USDC transfers).
Advantages:
- Portal-wrapped tokens are widely supported across DeFi ecosystems.
3. Router Nitro
Website: https://routernitro.com/
Overview: A fast, user-friendly multi-chain bridge with added features by Router Protocol.

Source: Router
Supported assets: Various assets across 30+ chains.
Key features:
- Gas airdrops to cover SUI fees;
- Single transaction transfer without connecting the destination wallet or interacting with it;
- Native Sui USDC bridge powered by CCTP;
- Token swap support from any supported chain to any token on Sui.
Advantages:
- Transfer times: Around 3 minutes for most supported chains;
- Multi-chain support, including rarely available bridges (e.g. Sui to Aptos).
- Built on the Router Chain, a blockchain designed specifically for secure and fast inter-blockchain communication.

Limitations:
- No native USDC transfers;
- No native ETH support.
5. Cetus

Source: Cetus
Features:
- Wormhole-powered bridge for native USDC and wrapped assets;
- Seamless within the DEX environment.
Best practices for bridging on SUI
A smooth and secure bridging experience requires understanding each platform's features. For example, Sui Bridge transfers ETH as native ETH, compatible with Sui’s ecosystem, while Wormhole transfers ETH as WETH.
Some other considerations for Sui bridge users:
- Choose well-established platforms with strong security audits;
- Have enough SUI tokens for transaction fees or use a bridge offering gas subsidies and native gas features;
- Check daily and per-transaction transfer limits;
- Test smaller amounts first.
Efficient bridging not only depends on the platform’s design but also requires robust blockchain infrastructure. RPC node services like GetBlock ensure that users and developers experience smooth interactions with SUI nodes.
