Submit a deposit transaction

With the returned tx_hex from step 1, you will need to sign it before submitting it.

How can I sign a Cardano transaction?

For in-depth API details Submit deposit transaction

curl

curl --location 'https://api-staging.deltadefi.io/accounts/deposit/submit' \
--header 'X-API-key: <your_api_key>' \
--header 'Content-Type: application/json' \
--data '{
    "signed_tx": "<your_signed_tx>"
}

NodeJs (axios)

const axios = require('axios');
let data = JSON.stringify({
  "signed_tx": "<your_signed_tx>"
});

let config = {

✅ Verifying deposit

After you have made a successful deposit request, you can check your latest account balance via the Balances API.

curl

curl --location 'https://api-staging.deltadefi.io/accounts/balance' \
--header 'X-API-KEY: <your_api_key>'

NodeJs

const axios = require('axios');

let config = {
  method: 'get',
  maxBodyLength: Infinity,
  url: 'https://api-staging.deltadefi.io/accounts/balance',
  headers: { 
    'X-API-KEY': '<your_api_key>'
  }
};

axios.request(config)
.then((response) => {
  console.log(JSON.stringify(response.data));
})
.catch((error) => {
  console.log(error);
});

Go

package main

import (
  "fmt"
  "net/http"
  "io"
)

func main() {

  url := "https://api-staging.deltadefi.io/accounts/balance"
  method := "GET"

  client := &http.Client {
  }
  req, err := http.NewRequest(method, url, nil)

  if err != nil {
    fmt.Println(err)
    return
  }
  req.Header.Add("X-API-KEY", "<your_api_key>")

  res, err := client.Do(req)
  if err != nil {
    fmt.Println(err)
    return
  }
  defer res.Body.Close()

  body, err := io.ReadAll(res.Body)
  if err != nil {
    fmt.Println(err)
    return
  }
  fmt.Println(string(body))
}

Your Response should look something like below:

[
    {
        "asset": "usdx",
        "asset_unit": "5066154a102ee037390c5236f78db23239b49c5748d3d349f3ccf04b55534458",
        "free": 0,
        "locked": 17.35
    },
    {
        "asset": "ada",
        "asset_unit": "",
        "free": 0,
        "locked": 100
    }
]
