# Token account

The `TokenAccount` family — 7 operations.

The kernel wallet holds the prepaid kernels your group runs on — one wallet per group, opened once. The balance and counters are server facts; set a low-balance warning, attach a billing method, and arm auto top-off so the wallet refills itself under a monthly cap.
