+### Two WASTR Implementations
+
+Astar EVM supports two WASTR contracts for different use cases. **Both are safe and fully functional.** Choose based on your specific needs.
+
+#### Official Astar WASTR (Recommended)
+**Contract Address:** `0x37795fdd8c165cab4d6c05771d564d80439cd093`
+
+- **Standard:** WETH9 (ERC-20 compatible)
+- **Deployed by:** Astar Foundation
+- **Chainlink CCIP Compatible:** Yes
+
+**Use for:**
+- Cross-chain bridging to Soneium via CCIP
+- All new dApp integrations
+- Future Astar ecosystem development
+
+**Block Explorer:** [View on Blockscout](https://astar.blockscout.com/token/0x37795FdD8C165CaB4D6c05771D564d80439CD093)
+
+#### Community WASTR (Legacy Support)
+**Contract Address:** `0xAeaaf0e2c81Af264101B9129C00F4440cCF0F720`
+
+- **Standard:** WETH10 (ERC-20 compatible with additional features)
+- **Deployed by:** Arthswap
+- **Additional Features:** Flash loans (ERC-3156), Permit, withdrawTo
+
+**Use for:**
+- Existing positions in Arthswap and legacy DeFi protocols
+- Applications requiring WETH10-specific features (flash loans, permit)
+
+**Block Explorer:** [View on Blockscout](https://astar.blockscout.com/token/0xAeaaf0e2c81Af264101B9129C00F4440cCF0F720)
+
+### Quick Decision Guide
+
+**Are you bridging to Soneium?**  
+→ Use Official Astar WASTR (`0x3779...`)
+
+**Building a new dApp?**  
+→ Use Official Astar WASTR (`0x3779...`)
+
+**Using Arthswap or legacy Astar DeFi protocols?**  
+→ Use Community WASTR (`0xAeaa...`)
+
+**Need flash loan functionality?**  
+→ Use Community WASTR (`0xAeaa...`)
+
+### For Developers
+
+#### Why Two Contracts?
+
+The Official Astar WASTR uses WETH9 for seamless integration with Chainlink CCIP's cross-chain messaging infrastructure, enabling native bridging to Soneium and future networks.
+
+The Community WASTR uses WETH10, offering advanced features like gasless approvals (permit) and flash loans, beneficial for complex DeFi interactions.
+
+#### Contract Compatibility
+
+Both contracts implement standard WETH functionality:
+- `deposit()` / `withdraw()`
+- Full ERC-20 interface
+- 1:1 ASTR backing
+
+**WETH10 additional methods:**
+```solidity
+flashLoan(IERC3156FlashBorrower receiver, address token, uint256 value, bytes calldata data)
+permit(address owner, address spender, uint value, uint deadline, uint8 v, bytes32 r, bytes32 s)
+withdrawTo(address to, uint256 value)
+```
+
+If you don't need these specific features, use the Official Astar WASTR for maximum ecosystem compatibility.
