# sendAsset | Hyperliquid exchange
> Sends a spot asset to another address on Hyperliquid L1. sendAsset JSON-RPC method available on the Hyperliquid exchange blockchain via Chainstack.
You can only use this endpoint on the official Hyperliquid public API. It is not available through Chainstack, as the open-source node implementation does not support it yet. See [Hyperliquid methods](/docs/hyperliquid-methods) for the full availability breakdown.
This endpoint requires signature authentication. See our comprehensive [Authentication via Signatures guide](/docs/hyperliquid-authentication-guide) for implementation details.
Sends a spot asset to another address on Hyperliquid L1.
## Parameters
### Required parameters
* `action` (object, required) — The action object containing:
* `type` (string) — Must be `"sendAsset"`
* `hyperliquidChain` (string) — Chain identifier
* `destination` (string) — Recipient address
* `token` (string) — Token to send
* `amount` (string) — Amount to send
* `time` (integer) — Current timestamp in milliseconds
* `nonce` (number, required) — Current timestamp in milliseconds (must be recent)
* `signature` (object, required) — EIP-712 signature of the action
### Optional parameters
* `vaultAddress` (string, optional) — Address when trading on behalf of a vault or subaccount
## Returns
Returns an object with the action status:
* `status` — `"ok"` if request processed
* `response` — Contains action result data
## Example request
```shell cURL theme={"system"}
curl -X POST https://api.hyperliquid.xyz/exchange \
-H "Content-Type: application/json" \
-d '{
"action": {"type": "sendAsset"},
"nonce": 1234567890123,
"signature": {...}
}'
```
```python Python (hyperliquid-python-sdk) theme={"system"}
import eth_account
from hyperliquid.exchange import Exchange
from hyperliquid.utils import constants
# Load your wallet from a private key (keep it secret — never hardcode in production)
wallet = eth_account.Account.from_key("0x...")
# Public Hyperliquid API (this method is available on the official API only)
exchange = Exchange(wallet, constants.MAINNET_API_URL)
# Send a spot asset to another address.
# sourceDex/destinationDex: "" for the default perp dex, "spot" for spot.
result = exchange.send_asset(
destination="0x0000000000000000000000000000000000000001",
source_dex="spot",
destination_dex="spot",

)
print(result)
```
```typescript TypeScript (@nktkas/hyperliquid) theme={"system"}
import { ExchangeClient, HttpTransport } from "@nktkas/hyperliquid";
import { privateKeyToAccount } from "viem/accounts";
// Load your wallet from a private key (keep it secret — never hardcode in production)
const wallet = privateKeyToAccount("0x...");
// Public Hyperliquid API (this method is available on the official API only)
const transport = new HttpTransport();
const exchange = new ExchangeClient({ transport, wallet });
// Send a spot asset to another address.
// sourceDex/destinationDex: "" for the default perp dex, "spot" for spot.
const result = await exchange.sendAsset({
destination: "0x0000000000000000000000000000000000000001",
sourceDex: "spot",
destinationDex: "spot",
token: "USDC:0xeb62eee3685fc4c43992febcd9e75443",
amount: "1",
});
console.log(result);
```
## Use case
* **Send asset** — Sends a spot asset to another address on Hyperliquid L1.
Always ensure your system clock is synchronized. Nonce must be within a reasonable time window of the current server time or the request will be rejected.
