xDAI Logo


The first-ever USD stable blockchain

Use Cases

Ethereum compatible smart-contract stable coin


xDai was originally a proof-of-authority chain that used an authority round (AuRa) consensus mechanism, supported by Parity and Nethermind. Nowadays, xDai has evolved into a permissionless delegated proof-of-stake based consensus with POSDAO.

The xDai network is designed for everyday crypto payments and transactions. Gas fees are extremely low, and payments are very fast. Its value remains stable at ~ $1 US Dollar per xDai.

We highly recommend xDai and have a lot of positive experience with this network.
