# YieldCreateEnterAction

> Generate unsigned deposit transaction calldata for a DeFi yield market

## Overview

`YieldCreateEnterAction` returns the unsigned transaction payload needed to deposit into a DeFi yield market. This is the low-level endpoint that backs the `lend` and `deposit` composable actions in the SDK.

Use this endpoint when building custom DeFi UIs outside React, or when you need to construct the calldata manually before passing it to Trails via the `to.calldata` param on `QuoteIntent`.

For React apps, use the `lend()` or `deposit()` action builders with `useTrailsSendTransaction` — they call this endpoint internally.

## Request Parameters

| Field               | Type   | Required | Description                                    |
| ------------------- | ------ | -------- | ---------------------------------------------- |
| `earnMarketId`      | string | Yes      | Market ID from `YieldGetMarkets`               |
| `userWalletAddress` | string | Yes      | Address of the depositing wallet               |
| `args`              | object | No       | Market-specific arguments (varies by protocol) |

## Response

Returns `payload` containing unsigned transaction data:

| Field                  | Description                             |
| ---------------------- | --------------------------------------- |
| `transactions`         | Array of transaction objects to execute |
| `transactions[].to`    | Contract address                        |
| `transactions[].data`  | ABI-encoded calldata                    |
| `transactions[].value` | ETH value (for native token deposits)   |

## Examples

### Build a deposit calldata for Aave

```typescript theme={null}
const response = await fetch('https://trails-api.sequence.app/rpc/Trails/YieldCreateEnterAction', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-Access-Key': 'YOUR_ACCESS_KEY',
  },
  body: JSON.stringify({
    earnMarketId: 'base-usdc-aave-v3-lending',
    userWalletAddress: '0xYourWalletAddress',
  }),
})

const { payload } = await response.json()
const action = JSON.parse(payload)

// Pass action.transactions[0].data to QuoteIntent as to.calldata
```

### With protocol-specific arguments

Some markets accept additional arguments (e.g. slippage, referral codes):

```typescript theme={null}
const response = await fetch('https://trails-api.sequence.app/rpc/Trails/YieldCreateEnterAction', {
  method: 'POST',
  headers: {
    'Content-Type': 'application/json',
    'X-Access-Key': 'YOUR_ACCESS_KEY',
  },
  body: JSON.stringify({
    earnMarketId: 'ethereum-usdc-morpho-0x...',
    userWalletAddress: '0xYourWalletAddress',
    args: {
      referralCode: 0,
    },
  }),
})
```

## SDK alternative

For React, use the `lend` or `deposit` builders with `useTrailsSendTransaction`:

```tsx theme={null}
import { useTrailsSendTransaction, lend, deposit } from '0xtrails'

const { sendTransaction } = useTrailsSendTransaction({
  actions: [
    lend({ marketId: 'base-usdc-aave-v3-lending', amount: '100' }),
  ],
})
```

See [Composable Actions](/use-cases/composable-actions) for the full SDK approach.
