# Function: offerToPhone()

```ts
function offerToPhone(params, onStage): Promise<PairingOffer>;
```

Defined in: [packages/core/src/session/pairing.ts:81](https://github.com/leifriksheim/minca/blob/main/core/src/session/pairing.ts#L81)

Starts offering an account to a phone; the first relay goes in the link.

One offer serves one phone: the first that commits is the only one answered.
The code stops working after `ttlMs` if no phone has used it, and as soon as
one has.
