# transfer

An entrypoint that transfer user's LP tokens to another account (tz/KT). Also it votes for sender's and recipient's bakers. If the recipient does not have a preferred baker, the current delegated will be chosen as the preferred baker. Works exactly like FA2 transfer entrypoint according to [TZIP-012](https://gitlab.com/tezos/tzip/-/blob/master/proposals/tzip-12/tzip-12.md). Also supports [TZIP-017](https://gitlab.com/tezos/tzip/-/blob/master/proposals/tzip-17/tzip-17.md) (permits).

{% tabs %}
{% tab title="🌮 Taquito" %}

```javascript
const dexCoreAddress = "KT1...";
const params = [
    {
        from_: "tz1.../KT1...",
        txs: [
            {
                to_: "tz1.../KT1...",
                token_id: 1,
                amount: 100,
            },
            ...
        ],
    },
    ...
];
const dexCore = await tezos.contract.at(dexCoreAddress);
const operation = await dexCore.methods.transfer(params).send();

await operation.confirmation();
```

{% endtab %}
{% endtabs %}
