Gas & fees

  • Gas model is EVM-standard (EIP-1559 compatible fields supported by the client).
  • Native gas token: MO (18 decimals).
  • Testnet gas is effectively free — use the faucet.

Hardforks

The chain follows the upstream BSC hardfork order (Luban → … → Maxwell → Fermi → … → Mendel). All block-based forks are activated at genesis; time-based forks (Feynman → Mendel) activate shortly after launch so system-contract initialization (e.g. StakeHub) runs through the standard upstream path.

note

Because we use the standard fork sequence rather than custom patches, mainnet migration only requires shifting fork timestamps — no new client risk is introduced.

Canonical addresses

Multicall3 is deployed at the canonical cross-chain address via Nick's method, so multicall-based tooling works without configuration:
