ONE chain

Deployed

Status — Deployed

● ONE chain is live. The chain has been deployed since 19 March 2026 and is reachable at chain.expl.one. It is the only ONE project currently in the Deployed stage.

What ONE chain is

ONE chain is the sovereign, gas-free EVM blockchain for the ONE ecosystem. It is the foundational chain that the ONE projects build on:

  • Sovereign — ONE chain runs as its own chain rather than as a layer or tenant of another network. Decisions about how it operates belong to the ONE ecosystem.
  • Gas-free — End-user interactions are not designed to require a separate gas token in front of every action.
  • EVM — The chain is EVM-compatible, so the broad ecosystem of Ethereum-style tools, contracts, and wallets carries over.

It is the only ONE project that has reached the Deployed stage at the time of writing.

How to use it

  • Visit chain.expl.one — the chain's project home.
  • Use any EVM-compatible wallet to interact with addresses and contracts on the chain.
  • Use ONE chain as the substrate underneath the rest of the ONE projects, in the same way the ecosystem itself is structured.

Public network parameters (chain ID, RPC endpoints, explorer URLs, and similar) belong on chain.expl.one and are not duplicated here so they cannot drift out of sync.

How it fits in the ONE ecosystem

ONE chain is the substrate the rest of the ONE ecosystem builds on. Every other ONE project is intended to settle, identify, and exchange value through it.

Current state

ONE chain is Deployed. It has been live since 19 March 2026 and is the only ONE project at the Deployed stage today. The other ONE projects sit on top of it and are at various In Progress and Coming Soon stages — see the Projects Overview for the full picture.
