2) AnyBlock Analytics Explorer is convenient for exploring recent transactions and blocks and locating common information quickly.
Main RPC is a load balancer with 4 nodes, health checks, and failover.
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/
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 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.
UI coming soon. More information including method calls here.
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.
Tenderly dashboard supports xDai transaction inspection - smart contracts can also be pushed to the dashboard for real-time monitoring.
