# Cancel Stream

To cancel the stream, you can follow example below.

```typescript
const sourceChain = CHAIN_ID_BSC;
const targetChain = CHAIN_ID_SOLANA;
const receiver = "<evm address>";
const sender = "<evm address>";
const tokenMint = "<solana mint address>";
const dataAccount = "<pubkey of stream data account>";

const cancelReceipt = await ethClient.cancelStream(sender, receiver, tokenMint, dataAccount);
```

Now you can find signed Vaa bytes of your payload sent to wormhole.

```typescript
const sequence = parseSequenceFromLogEth(cancelReceipt, getBridgeAddressForChain(sourceChain));
const emitterAddress = getEmitterAddressEth(BSC_ZEBEC_BRIDGE_ADDRESS);

const { vaaBytes } = await getSignedVAAWithRetry(
   WORMHOLE_RPC_HOSTS,
   sourceChain,
   emitterAddress,
   sequence,
);
```

Now post this signed vaa to wormhole solana core bridge program, parse the payloads from vaa and send the parsed data to solana zebec bridge program. This part is optional because it's handled by zebec's specialized relayer.

```typescript
const payerAddress = wallet.publicKey.toString();
const bridgeAddress = getBridgeAddressForChain(targetChain);
const vaaBuf = Buffer.from(vaaBytes);

setDefaultWasm("node"); // use bundler for browser

// posting vaa in solana
await postVaaSolanaWithRetry(
   connection,
   wallet.signTransaction,
   bridgeAddress,
   payerAddress,
   vaaBuf,
   MAX_VAA_UPLOAD_RETRIES_SOLANA,
);

const parsedVaa = parse_vaa(cancelStreamVaa);
const parsedPayload = parseZebecPayload(Buffer.from(parsedVaa.payload));

const result = await solanaClient.cancelStream(cancelStreamVaa, <CancelTokenStreamPayload>parsedPayload);
```

# Agent Instructions: Querying This Documentation

If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter:

```
