RealX's REX Chain Mainnet Goes Live on Avalanche

REX Chain, the network built by RealX, has launched its mainnet on Avalanche, the project's official account is_realx announced on Oct. 21, 2026. The Avalanche account avax amplified the launch through a retweet rather than an original post.

REX Chain positions the launch as the start of a "unified market for onchain finance," according to is_realx, which described the mainnet going live as a new chapter for RealX. The project did not disclose additional technical details, metric targets or partner commitments in the announcement itself.

The launch places REX Chain in Avalanche's broader ecosystem of purpose-built networks, which the avax account has recently promoted as a route for institutions seeking custom chain environments while remaining connected to the wider Avalanche network.

Mainnet going live is typically the point at which a network opens to public usage after testnet phases. For Avalanche ecosystem watchers, the REX Chain deployment adds another application-specific venue aimed at financial use cases, an area where Avalanche has concentrated institutional messaging in recent weeks, including tokenization and cross-border payments initiatives.

What to watch next: whether RealX publishes details on REX Chain's validator set, its bridge or interoperability path to the primary Avalanche network, and any initial applications or assets deploying at launch.
