# TxChildkeyTakeRateLimitExceeded (/docs/errors/chain/TxChildkeyTakeRateLimitExceeded)

`set_childkey_take` was called again for the hotkey on this subnet before its rate-limit window elapsed. Check the block of the last childkey-take change against `TxChildkeyTakeRateLimit` and wait out the remainder.

Declared by the `SubtensorModule` pallet; it classifies to the semantic code [`rate_limited`](/docs/errors/rate-limited).

## Remediation [#remediation]

Wait for the rate-limit window to pass, then retry

The same explanation is available in the terminal: `btcli explain TxChildkeyTakeRateLimitExceeded`.
