# stx\_transferSip9Nft

Request a transfer of a SIP-009 non-fungible token to a specified recipient.

## Method name

`stx_transferSip9Nft`

The app must be connected first, through [`getAddresses`](/developers/methods/getaddresses.md). Leather signs with the account the app connected with.

Leather builds a call to the collection contract's `transfer` function and attaches its own post-condition: the sender sends the token identified by `assetId`. The request's `postConditions` and `postConditionMode` are not applied.
