xDai Stable Chain

The xDai chain is a stable payments blockchain designed for fast and inexpensive transactions. The chain uses a unique dual-token model; xDai is a stable token used for transactions, payments, and fees, and STAKE is a governance token used to support the underlying POSDAO Proof-of-Stake consensus.

🌉 xDai Bridges provide the seamless ability to move tokens between chains using the unique TokenBridge Architecture. Tokens and arbitrary messages can also be passed across chain.

Project Highlights

The xDai ecosystem continues to flourish with many new project migrations, integrations, applications, and a mature toolset for developers. Explore the depth of the xDai ecosystem in the Project & DApps section.

xDai Developers

Development on xDai is easy and intuitive for Ethereum developers. xDai is an EVM sidechain, and smart contracts can be written and deployed in exactly the same way simply by setting a different RPC endpoint.

Any contract that works on the Ethereum mainnet can be redeployed to the xDai chain. On the xDai chain, transaction costs are minimized, and all fees and transactions are paid with a single token, xDai. Many tools supporting Ethereum development are compatible with xDai, including:

• ​TheGraph​

• ​Tenderly​

• ​Remix​

• ​OpenZeppelin​

• ​BlockNative​

• ​Gnosis Safe MultiSig​

• ​Dune Analytics​

• Many more......
