Introduction to Sui Bridge
Sui Bridge is a native bridging protocol specifically designed for securely transferring assets and data between Sui and Ethereum networks. This innovative solution enables seamless movement of ETH, wBTC, USDC, and USDT across chains while leveraging Sui's inherent security and speed. Supported by Sui network validators, this protocol establishes a vital infrastructure component for the growing Sui ecosystem.
Why Bridging Matters for DeFi Ecosystems
As blockchain ecosystems expand, secure bridging solutions become fundamental to healthy DeFi environments by:
- Enabling cross-chain interoperability
- Facilitating asset and data flow between networks
- Enhancing liquidity pools
- Expanding digital asset utility
- Simplifying user participation across DeFi and gaming platforms

- Operates under the same security mechanisms protecting the Sui blockchain
- Maintains trust through validator-backed operations
- Eliminates reliance on external verification systems
- Provides enterprise-grade protection for all cross-chain transfers
Testnet Incentive Program Details
To celebrate the testnet launch, Sui Foundation has allocated 100,000 SUI tokens to reward participants who help stress-test the system. The program focuses on:
Participation Requirements
- Complete full bidirectional transfers (Ethereum↔Sui)
- Use only the official web interface (direct contract calls invalidate eligibility)
- Document and report genuine edge cases with reproduction steps
- Check existing resources before submitting duplicate reports
Rewards Structure
| Contribution Type | Reward Potential |
|---|---|
| Critical bug reports | Highest tier allocation |
| UI/UX improvements | Moderate rewards |
| General testing | Base participation rewards |
Testing Methodology
Asset Preparation
- Obtain testnet tokens from approved faucets
