preflight_check_big_blocks

Documentation for eth_defi.hyperliquid.block.preflight_check_big_blocks function.

preflight_check_big_blocks(web3, private_key)

Verify big blocks can be toggled before starting a deployment on HyperEVM.

Performs a quick enable/disable round-trip against the Hyperliquid exchange API. If the deployer address has never performed an L1 action (e.g. a spot transfer), the API will reject the request and this function raises HyperEVMBigBlocksError with a clear message, rather than letting the deployment fail mid-way with an opaque “exceeds block gas limit” error.

No-op on non-HyperEVM chains and Anvil forks.

Parameters

  • web3 (web3.main.Web3) – Web3 connection.

  • private_key (str) – Hex-encoded deployer private key.

Raises

HyperEVMBigBlocksError – If the Hyperliquid exchange API rejects the big blocks toggle.

Return type

None
