Hyperliquid Unified Account Migration for API Trading Bots

A migration guide for trading bots moving from legacy Hyperliquid balance assumptions to unified account behavior.

Detect the account mode explicitly

Account abstraction changes where balances and holds appear. Read and record the current mode rather than inferring it from a non-zero field.

Refactor reconciliation

Create one normalized portfolio view for spot assets, perp positions, open orders, holds and transfers. Test empty and partially migrated states with captured fixtures.

Review action limits and signers

Mode-changing actions and builder approvals may require different signing authority than routine API trading. Keep master-wallet actions outside the hot execution path.

Use a reversible rollout

Run old and new readers side by side, compare normalized equity, then enable trading with low limits. Retain a kill switch if the mode or returned schema is unexpected.
