Why XDC Network?

XDC Network is an enterprise-grade Layer-1 blockchain focused on:

• Trade Finance: Tokenization of trade finance assets
• RWA (Real World Assets): Growing ecosystem of tokenized real-world assets
• Low Fees: Sub-cent transaction fees (often <$0.0001)
• Fast Finality: ~2 second block times
• Energy Efficient: XDPoS 2.0 consensus

Ecosystem Growth

• Listed on MetaMask (default network)
• Listed on DefiLlama
• Support in viem.sh
• Support in Safe (Gnosis Safe)
• Active DeFi ecosystem with DEXs, lending protocols

Technical Requirements

1. Add XDC chain info to packages/uniswap/src/features/chains/evm/info/
2. Update UniverseChainId enum in types
3. Add chain to ORDERED_CHAINS
4. Deploy Uniswap contracts on XDC (if not already)

Resources

• Website: https://xdc.network
• Documentation: https://docs.xdc.network
• GitHub: https://github.com/XinFinOrg
• XDC in viem: https://viem.sh/docs/chains/xdc

Additional Context

XDC is already supported in:

• ✅ MetaMask (default network list)
• ✅ viem.sh
• ✅ RainbowKit
• ✅ Thirdweb
• ✅ Safe (Gnosis Safe)
• ✅ DefiLlama

Would love to see Uniswap support this growing enterprise blockchain!

Start by inspecting packages/uniswap/src/features/chains/evm/info/ and the types defining UniverseChainId, then trace how ORDERED_CHAINS is assembled. Verify whether Uniswap contracts are deployed on XDC before deciding the implementation scope. Done means XDC Network with chain ID 50 is consistently represented in the interface and any required deployment work is accounted for.
