# OutOfTransientStorage (/docs/errors/chain/OutOfTransientStorage)

A write would exceed the per-execution byte limit for transient storage. Check how much data the contract places in transient storage during the call against the runtime's transient storage limit.

Declared by the `Contracts` pallet; it classifies to the semantic code [`limit_exceeded`](/docs/errors/limit-exceeded).

## Remediation [#remediation]

A chain-side capacity limit was hit; reduce the size or count of the request

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