Single-chain intents let you make transactions on a chain of your choice. These intents are similar to ERC-4337 User Operations. See our concepts section on intents vs userops to better understand the difference. Relayers execute single-chain intents through the intent executor module. For a breakdown of the high-level flow, please take a look at the Rhinestone Intents concepts section.

​
Example

Here’s how you can make a token transfer: 
const singleChainTx = await rhinestoneAccount.sendTransaction({
  chain: base,
  calls: [
    {
      to: 'USDC',
      data: encodeFunctionData({
        abi: erc20Abi,
        functionName: 'transfer',
        args: [recipient, parseUnits('5', 6)],
      }),
    },
  ],
})

​
Gas Limit

You can override the default gas limit for the target chain execution with gasLimit. Doing this will make the intent better priced, because we can more accurately calculate the fee that a solver needs to be reimbursed with for paying the gas. If this is not provided, we calculate using a gas limit of 1_000_000. 
const transaction = await rhinestoneAccount.sendTransaction({
  chain: base,
  calls: [
    // …
  ],
  tokenRequests: [
    // …
  ],
  gasLimit: 200_000n,
})

​
Source Assets

You can specify what token (or tokens) to use as an input asset: 
const transaction = await rhinestoneAccount.sendTransaction({
  chain: base,
  calls: [
    // …
  ],
  tokenRequests: [
    // …
  ],
  sourceAssets: ['USDC', 'ETH']
})

​
Auxiliary Funds

In case you have funds not available immediately for an intent (e.g. locked in a vault or sitting in an exchange), you can specify them as auxiliary funds: 
const transaction = await rhinestoneAccount.prepareTransaction({
  chain: base,
  calls: [
    // …
  ],
  tokenRequests: [
    // …
  ],
  auxiliaryFunds: {
    [base.id]: {
      [USDC_ADDRESS]: parseUnits('100', 6),
      [WETH_ADDRESS]: parseUnits('1', 18)
    }
  }
})
This lets you get a quote before getting the funds ready on the account.

​
Wait for Execution

sendTransaction returns a pending intent. To wait until it gets executed, use waitForExecution: 
const transaction = await rhinestoneAccount.sendTransaction({
  // …
})
const transactionResult = await rhinestoneAccount.waitForExecution(transaction)
By default, intents are pre-confirmed by a relayer to be executed before they actually land onchain. You can opt out of this by waiting for onchain execution: 
const acceptPreconfirmations = false;
const transactionResult = await rhinestoneAccount.waitForExecution(transaction, acceptPreconfirmations)

​
Get Intent Status

You can also fetch the intent status directly to implement a custom polling logic: 
const transaction = await rhinestoneAccount.sendTransaction({
  // …
})
const transactionResult = await rhinestone.getIntentStatus(transaction.id)
