Bridging digital assets to new blockchain ecosystems and leveraging them in decentralized finance (DeFi) protocols is a powerful way to grow your crypto holdings. The Sui Network, known for its high-speed, low-cost transactions and innovative Move-based programming language, is rapidly gaining traction in the DeFi space. One of the leading platforms on Sui is Scallop, a lending and borrowing protocol designed to maximize capital efficiency.
This guide walks you through the complete process of bridging assets to Sui using trusted cross-chain solutions and providing liquidity on Scallop to earn passive income. Whether you're new to Sui or expanding your DeFi strategy, this step-by-step tutorial ensures a smooth and secure experience.
Why Bridge to Sui and Use Scallop?
Sui offers sub-second transaction finality and negligible gas fees, making it ideal for active DeFi participation. Scallop, as the first DeFi project officially funded by the Sui Foundation, brings robust security and innovative features to users.
By bridging assets like ETH or USDC from Ethereum or other EVM chains, you unlock opportunities to:
- Earn competitive interest on supplied assets
- Borrow against your collateral
- Participate in a rapidly growing ecosystem

Step-by-Step: Bridge Assets to Sui Network
Step 1: Access the Scallop Bridge
Go to the official Scallop DApp at https://app.scallop.io/ and click on the “Bridge” tab. Scallop integrates with leading cross-chain interoperability protocols — Wormhole, Portal, and Celer — enabling seamless transfers from major blockchains like Ethereum, BSC, Polygon, Avalanche, Solana, and more.

While all options work well, Wormhole is recommended for its user-friendly interface and reliability.
Step 2: Select Source and Target Chains
Choose your source chain (e.g., Ethereum) and set Sui as the target chain. You’ll need two wallets:
- An EVM-compatible wallet (like MetaMask) for your source chain
- A Sui-compatible wallet (like Suiet or Martian) for receiving funds
Connect both wallets, then select the token (e.g., ETH or USDC) and the amount you wish to transfer.
Step 3: Choose Your Gas Payment Method
When bridging from Ethereum to Sui, you have two options to cover transaction fees:
Option 1: Pay with Source Chain Native Token (Recommended)
Use ETH or USDC from your Ethereum wallet to pay the bridge fee. This method requires only one transaction, making it faster and simpler — perfect for beginners.
Option 2: Pay with ETH + SUI
If you already hold $SUI, you can split the fee between ETH and SUI. However, this involves two separate transactions and requires manually entering a transaction ID, increasing complexity.
Additionally, enable the “Native gas” option if you'd like to receive a small amount of $SUI upon arrival. This converts part of your bridged asset into $SUI, ensuring you have gas for future actions on the Sui network.
The interface clearly shows your expected balances post-bridge — both the received token (e.g., USDC) and any $SUI obtained via gas conversion.
Pro Tip: Stick with Option 1 unless you're comfortable managing multi-step transactions.
Step 4: Confirm and Approve Transaction
Double-check all details — destination address, token amount, and gas settings. Ensure your wallet has enough balance to cover fees. Once verified, approve the transaction through your wallet.
Wait for blockchain confirmations. Depending on network congestion, bridging typically takes 5–10 minutes.
Step 5: Completion
Upon successful transfer, you’ll see a confirmation screen showing the completed bridge. Your assets are now available in your Sui wallet, ready for use in DeFi applications like Scallop.
How to Provide Liquidity on Scallop Lending Pools
Now that your assets are on Sui, it’s time to put them to work.
Scallop operates as a non-custodial lending protocol where users supply assets into liquidity pools and earn interest generated by borrowers.
Step 1: Connect Wallet and Navigate to Lending
Return to https://app.scallop.io/ and click the “Lending” tab. Connect your Sui wallet — supported options include Martian, Suiet, ELLI, and Ethos.
Once connected, you’ll see available lending pools. Currently, Scallop supports:
- $SUI
- $USDC
These stable and high-utility assets offer strong demand for borrowing, translating into consistent yield for lenders.
👉 Maximize your idle crypto with high-yield lending opportunities.
Step 2: Supply Assets to a Lending Pool
Select the pool you want to contribute to (e.g., USDC). Click “Supply”, enter the amount, and confirm.
For example:
- If you bridged 100 USDC, you can supply any portion of that balance.
- Interest accrues in real-time and can be claimed anytime.
Step 3: Confirm Wallet Transaction
Your wallet will prompt you to approve the supply action. Verify the amount and network details before confirming.
After confirmation, your assets are deposited into the pool. You’ll receive sTokens (Scallop’s interest-bearing tokens) representing your share of the pool.
You can withdraw funds at any time by clicking “Withdraw” — no lock-up periods or penalties.
How to Borrow Against Your Collateral
Scallop also allows users to borrow assets by locking up collateral — ideal for leveraging positions without selling your holdings.
Step 1: Deposit Collateral
Go to the “Collateral” tab and choose which asset (SUI or USDC) you’d like to deposit. Enter the amount and click “Deposit.”
This action secures your borrowing power based on the asset’s loan-to-value (LTV) ratio.
Step 2: Borrow an Asset
Navigate to the “Borrowing” tab. Select the asset you want to borrow (subject to availability and LTV limits), input the amount, and click “Borrow.”
Once confirmed, funds are instantly credited to your wallet.
Remember: Maintain a healthy collateral ratio to avoid liquidation during price volatility.
Frequently Asked Questions (FAQ)
Q: Which blockchains can I bridge from to Sui using Scallop?
A: You can bridge from Ethereum, BSC, Polygon, Avalanche, Fantom, Celo, Moonbeam, Solana, and other major chains via Wormhole, Portal, or Celer integrations.
Q: Is there a minimum amount required to provide liquidity on Scallop?
A: No. Scallop does not enforce minimum deposits, allowing both small and large investors to participate freely.
Q: How is interest calculated on supplied assets?
A: Interest is computed in real-time based on utilization rates within each pool. Rates fluctuate dynamically depending on borrower demand.
Q: Can I lose money providing liquidity on Scallop?
A: Since Scallop uses over-collateralized loans, there’s minimal risk of insolvency. However, impermanent loss isn’t applicable here (as it’s not an AMM), but always monitor smart contract risks inherent in DeFi.
Q: Do I need $SUI to interact with Scallop after bridging?
A: Yes. While some bridges offer native gas delivery, having a small amount of $SUI ensures you can pay for transaction fees when supplying, borrowing, or withdrawing.
Q: Is Scallop audited and secure?
A: Scallop has undergone security reviews and received official support from the Sui Foundation, indicating strong protocol credibility.
