# Receipts

> The rail and status of a send, and what a receipt does and does not tell you.

Every send returns a receipt. The receipt tells you which rail ran and how far the send has
progressed. Neither `"submitted"` nor `"pending"` means confirmed.

## Rail

`rail` is `"self-pay"` or `"sponsored"` on both chains. It is the only field that tells you which
path actually ran. If your app promises fee-in-token, check it rather than assuming your
configuration took effect.

## EVM receipt

```ts theme={null}
type Receipt = {
  id: string;          // txHash (self-pay) or userOpHash (sponsored)
  rail: "self-pay" | "sponsored";
  status: "pending" | "submitted" | "confirmed" | "failed";
  txHash?: Hex;
  chainId: number;
  error?: string;
};
```

* **Self-pay:** `id` is a transaction hash; `status` starts at `"submitted"` (broadcast, not
  mined).
* **Sponsored:** `id` is a userOpHash, an intent id, not a transaction hash; `status` is
  `"pending"` until the bundler reports a receipt.

## Solana receipt

```ts theme={null}
type Receipt = {
  id: string;
  rail: "self-pay" | "sponsored";
  status: "pending" | "submitted" | "confirmed" | "failed" | "expired";
  signature?: string;
  cluster: "mainnet" | "devnet";
  lastValidBlockHeight?: bigint;
  error?: string;
};
```

Solana adds an `"expired"` status, a transaction whose blockhash lapsed before it confirmed.

* **Self-pay:** `status` starts at `"submitted"`.
* **Sponsored:** `status` starts at `"pending"`.

Both carry a real `signature`.

## Confirming

To advance a receipt's status, poll the send engine's status method (or the provider's
`wallet_getCallsStatus` on EVM). Only `"confirmed"` means the transaction is on chain. See [Sponsor
EVM sends](/guides/sponsor-evm) and [Sponsor Solana sends](/guides/sponsor-solana).
