# Usdt0Manager (https://dev.cosmospay.lat/docs/sdk/definitions/server/usdt0-manager/)

> USDT0 from Stellar to EVM networks: client.usdt0. USDT0 is Tether's omnichain USDT.

USDT0 from Stellar to EVM networks: `client.usdt0`. USDT0 is Tether's omnichain USDT. From Stellar it travels through LayerZero's OFT: Ethereum receives native USDT, every other network receives USDT0, and every route takes an EVM recipient. Signing works like a swap: the API builds the transaction, the holder signs it, and {@link submit} relays the signed XDR. The holder pays LayerZero's fee and the network fee in XLM. Mainnet only: a `dev` key gets `available: false` from {@link routes}, and `400 network_unsupported` from {@link quote} and {@link create}.

## Methods

### routes()

The networks USDT0 can be sent to from Stellar, with the token and OFT a transfer uses.

```ts
routes(): Promise<Usdt0RoutesData>
```

**Returns** `Promise<Usdt0RoutesData>`

### quote()

Price a transfer: what is sent and arrives, the dust, LayerZero's fee and the OFT's limits. Persists nothing.

```ts
quote(options: QuoteUsdt0Options): Promise<Usdt0QuoteData>
```

**Parameters**

- `options`: `QuoteUsdt0Options`

**Returns** `Promise<Usdt0QuoteData>`

### create()

Build a transfer: the one unsigned Soroban transaction the holder signs (XDR and SEP-7 link).

```ts
create(options: CreateUsdt0TransferOptions): Promise<Usdt0Transfer>
```

**Parameters**

- `options`: `CreateUsdt0TransferOptions`

**Returns** [`Promise<Usdt0Transfer>`](https://dev.cosmospay.lat/docs/sdk/definitions/server/usdt0-transfer/)

### list()

List your transfers, newest first, as last refreshed (fetch one to refresh it).

```ts
list(options?: ListUsdt0TransfersOptions): Promise<Usdt0TransferPage>
```

**Parameters**

- `options` _(optional)_: `ListUsdt0TransfersOptions`

**Returns** `Promise<Usdt0TransferPage>`

### fetch()

Get one transfer. While PENDING or SUBMITTED the API refreshes it from the Stellar ledger and LayerZero Scan (at most every 15 seconds).

```ts
fetch(id: string, options?: Usdt0RecordTokenOptions): Promise<Usdt0Transfer>
```

**Parameters**

- `id`: `string`
- `options` _(optional)_: `Usdt0RecordTokenOptions`

**Returns** [`Promise<Usdt0Transfer>`](https://dev.cosmospay.lat/docs/sdk/definitions/server/usdt0-transfer/)

### submit()

Relay the signed transaction to Stellar mainnet. It must be the transaction the API built for this transfer, signed. A refusal by the network leaves it PENDING (`submitted: false`, `reason`) to submit again until it expires.

```ts
submit(id: string, options: SubmitUsdt0TransferOptions & Usdt0RecordTokenOptions): Promise<Usdt0SubmitOutcome>
```

**Parameters**

- `id`: `string`
- `options`: `SubmitUsdt0TransferOptions & Usdt0RecordTokenOptions`

**Returns** `Promise<Usdt0SubmitOutcome>`
