Additional resources to connect to xDai network

​🚀 QuikNode also supports xDai. Devs can get their own custom endpoint for DApps or other needs. https://blog.quiknode.io/xdai-network-is-live-on-quiknode/​

TokenBridge

There are two bridge implementations connecting xDai and the Ethereum Mainnet.

​xDai Bridge: ERC20-to-Native TokenBridge implementation, used for transferring Dai <-> xDai between Ethereum and the xDai chain.

​ETH-xDai Arbitrary Message Bridge: AMB between Ethereum and xDai for data, token and message transfers. Includes the Ominibridge extension for transfer of any ERC20 cross-chain.

xDai Bridge Access

• xDai Bridge UI at https://dai-bridge.poa.network​

  • Interaction using method calls for smart contracts ​https://docs.tokenbridge.net/xdai-bridge/how-to-use-xdai-bridge-without-ui​

• Bridge UI is built-in into AlphaWallet, BurnerWallet, BurnerFactory and other applications.

OmniBridge Access

• UI coming soon. More information including method calls here.​

DApp Management & Developer Tools

• ​Biconomy allows for gasless transactions and improved DApp UX.

• ​TheGraph supports xDai data indexing, querying and display.

• ​QuikNode gives users a super-fast Web3 endpoint for accessing or interacting with the xDai chain.

• ​Pocket provides a decentralized API layer for DApp developers (IOS, Android & Web SDKs available) and blockchain users.

• ​CurveGrid provides smart contract deployment, interaction and updating capabilities through a web UI as well as a comprehensive REST API.

• ​3Box: Externally Owned Account (EOA) addresses are the same on xDai as they are on other EVM networks, so no changes are needed to implement 3box functionality.

• ​BlockNative supports real-time notification & transaction monitoring with API and SDK tools.

Dashboards & Monitoring

• ​Tenderly dashboard supports xDai transaction inspection - smart contracts can also be pushed to the dashboard for real-time monitoring.

• Chainbeat provides monitoring and analytics tools for DApp developers.

• ​Dappquery analytics dashboard, customizable visualizations, smart contract alerts and scalable GraphQL API.
