Chain Specs
Consensus & timing
| Parameter | Value |
|---|---|
| Consensus | Parlia PoSA + BLS fast finality |
| Target block time | ~450 ms |
| Validator set | 4 (testnet) |
| Client | bnb-chain/bsc v1.7.3 fork |
| System contracts | bsc-genesis-contract v1.2.5 |
Gas & fees
- Gas model is EVM-standard (EIP-1559 compatible fields supported by the client).
- Native gas token:
SUP(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:
