What Does This Setting Do?

Hyperliquid processes transactions in two types of blocks. The block size toggle in HypurrFi lets you pick which type your transactions use:
  • Small blocks (default) — confirms in ~1 second. Best for everyday actions like swaps, deposits, borrows, and repayments.
  • Big blocks — confirms in ~1 minute but supports much larger transactions. Use this if a transaction fails due to gas limits.
Most users should leave this on Small blocks. You only need Big blocks for unusually large or complex transactions.

​
How to Change It

  1. Open the HypurrFi app
  2. Go to Settings
  3. Under “Set your preferred block size”, choose Small blocks or Big blocks

​
When to Use Big Blocks

  • A transaction fails with a gas limit error
  • You are deploying or interacting with a complex smart contract
  • You are batching many operations in a single transaction

​
Technical Details

Hyperliquid’s dual-block architecture splits EVM throughput between the two block types:
  • Small blocks: every ~1 second, 2M gas limit
  • Big blocks: every ~1 minute, 30M gas limit
For more details, see the Hyperliquid dual-block architecture docs.
