# eth\_getTransactionCount

{% hint style="info" %}
This behavior is disabled by default and only enabled for allowlisted originators. If you would like it enabled for your custom endpoint, please let us know.
{% endhint %}

If `eth_getTransactionCount` is submitted with the `"pending"` param, Blink intercepts the call, looks up the most recent transaction it has accepted for that address within the last **3 hours** — or the last **96 seconds** if you use revert protection — and returns the greater of:

* the node's pending transaction count, and
* Blink's latest recorded nonce for that address **+ 1**

If Blink has no recent transaction for the address, or the node's pending count is higher, the node response is returned unchanged.

Only transactions Blink accepted for submission are counted. A transaction we declined does not raise the nonce, so you are never handed a nonce that skips one we never forwarded.

The shorter window for revert protection is deliberate: those submissions are dropped after 96 seconds, so past that point the nonce is free again and bumping past it would hand you a gap.

All calls with a block tag other than `"pending"` (for example `"latest"` or `"earliest"`) will return responses directly from our Ethereum nodes.
