Building on SGA? Set evmVersion: shanghai

SGA runs the Shanghai EVM. Solidity 0.8.25+ targets Cancun by default, which produces opcodes SGA does not execute (invalid opcode). Always set the EVM version explicitly — see Developers below.

Mainnet roadmap

Testnet today. Mainnet next.

  1. Done

    Public testnet live

    5 validators, 3-second blocks, explorer & faucet open.

  2. In progress

    Testnet hardening & continuous operation

    Uptime history, monitoring, and operational evidence accumulate here, in the open.

  3. Planned

    Production validator key ceremony

    Hardened key generation, offline backups, HSM custody.

  4. Planned

    External security audit

    Independent professional review before any mainnet genesis.

  5. Planned

    Mainnet genesis & launch

    Chain ID 20260, MoSE, generated by our deterministic, fail-closed genesis pipeline.

We ship gates, not deadlines. Each step opens only when the previous one is proven — no launch dates are promised.
