# Sample Transactions
## Overview
Here are some samples of the transaction object that is created in [create transaction](/api-integration/main-api-multi-step/api-reference/create-transaction.md) method. Rango currently returns 6 different types of transactions based on the blockchain that the transaction is happening on. This includes:
* **EVM**: For all EVM-based blockchains, including Ethereum, Polygon, Avalanche, etc.
* **COSMOS**: For all the cosmos-based networks, including the Cosmos itself, Osmosis, Akash, Thorchain, Maya and etc.
* **TRANSFER**: For UTXO blockchains, including Bitcoin, Litecoin, Doge, etc.
* **SOLANA:** For Solana transactions.
* **TRON:** For Tron Transactions.
* **STARKNET:** For Starknet transactions.
* **SUI:** For SUI transactions.
* **XRPL:** For XRPL transactions.
* **STELLAR**: For Stellar transactions.
Let's see some examples here.
## EVM Sample Transaction: [(Test)](https://app.rango.exchange/bridge?fromBlockchain=BSC\&fromToken=BUSD--0xe9e7cea3dedca5984780bafc599bd69add087d56\&toBlockchain=AVAX_CCHAIN\&toToken=AVAX)
Here is the structure of an EVM transaction in the code below.
If the user lacks sufficient approval for the transaction, the create transaction method will respond with an approval transaction. (`isApproval` field is `true` in this case.) The user must first sign this approval transaction to ensure they have the necessary approval. Then, they should call the create transaction method again to obtain and sign the main transaction. The fields and schema for the approval and main transactions are identical.
{% hint style="info" %}
For the gas price of the transaction, if the blockchain supports the new versions of gas price, such as `maxPriorityFeePerGas` and `maxFeePerGas`, these fields will be populated. However, for blockchains that have not yet updated their gas model, the gas price will be set in the `gasPrice` field as before. You can check the list of all chains that support the new gas price versions in the `meta` or `blockchains` methods. (There is an `enableGasV2` field in the response body, included for each blockchain.)

## COSMOS Sample Transaction:
For Cosmos based blockchains, we have two type of transactions based on `signType` field: `AMINO` and `DIRECT`.

### Cosmos Direct Sample Transaction: [(Test)](https://app.rango.exchange/bridge/?fromBlockchain=JUNO\&fromToken=JUNO\&toBlockchain=JUNO\&toToken=USDC--ibc%2Feac38d55372f38f1afd68df7fe9ef762dcf69f26520643cf3f9d292a738d8034\&fromAmount=1)
This type is only used in limited swappers like WYNDDex (and Juno Blockchain) and we are going to deprecate support for Cosmos Direct transaction types whenever possible. You could sign this type of transactions using Stargate Client library.

## Tron Sample Transaction: [(Test)](https://app.rango.exchange/bridge/?fromBlockchain=TRON\&fromToken=TRX\&toBlockchain=TRON\&toToken=USDT--TR7NHqjeKQxGTCi8q8ZY4pL8otSzgjLj6t)

## Starknet Sample Transaction: [(Test)](https://app.rango.exchange/bridge/?fromBlockchain=STARKNET\&fromToken=ETH--0x49d36570d4e46f48e99674bd3fcc84644ddd6b96f7c741b1562b82f9e004dc7\&toBlockchain=STARKNET\&toToken=USDT--0x68f5c6a61780768455de69077e07e89787839bf8166decfbf92b645209c0fb8\&fromAmount=1)
Here is the structure of a Starknet transaction. Like EVM transactions, it can be either an approval transaction or a main transaction, depending on the `isApproval` field. Whenever possible, in Starknet, we batch the approval and main transactions into a single transaction using the `calls` array, as shown in the example below.
```json

## Solana Sample Transaction: [(Test)](https://app.rango.exchange/bridge/?fromBlockchain=SOLANA\&fromToken=USDT--Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB\&toBlockchain=SOLANA\&toToken=SOL\&fromAmount=1)
{% hint style="warning" %}
**Base64 Encoding**
Remember to broadcast the signed transaction to Solana RPCs with **base64** encoding. The **base58 encoding is deprecated**, but it is still the default method in Solana [docs](https://solana.com/docs/rpc/http/sendtransaction).
{% endhint %}
{% hint style="info" %}
**Versioned vs Legacy**
All supported routes for Solana are `VERSIONED` transactions except a special case of converting `SOL` to `WSOL` or vice versa via Solana Wrapper. (which you can ignore it.)
* [Sample for versioned transaction](https://app.rango.exchange/bridge/?fromBlockchain=SOLANA\&fromToken=USDT--Es9vMFrzaCERmJfrF4H2FYD4KCoNkY11McCe8BenwNYB\&toBlockchain=SOLANA\&toToken=SOL\&fromAmount=1)
* [Sample for legacy transaction](https://app.rango.exchange/bridge/?fromBlockchain=SOLANA\&fromToken=SOL\&toBlockchain=SOLANA\&toToken=WSOL--So11111111111111111111111111111111111111112\&fromAmount=1)

## SUI Sample Transaction:[(Test)](https://app.rango.exchange/bridge/?fromBlockchain=SUI\&fromToken=SUI--0x2%3A%3Asui%3A%3ASUI\&toBlockchain=BSC\&toToken=BNB\&fromAmount=15)
{% hint style="info" %}
**Key Notes:**
* The **unsignedPtbBase64** field is a base64-encoded string that contains the transaction's raw data. This is typically used to create the signed transaction, which would then be broadcasted to the blockchain.
{% endhint %}

## XRPL Sample Transaction:[(Test)](https://api.rango.exchange/basic/swap?from=XRPL.XRP\&to=BASE.ETH\&amount=50000000)

**Key Notes:**
* **Trust lines (IOUs):** When the destination token is not the native XRP, you need to set up a trust line to the issuer account before the swap (wallets can sign this as a pre-tx)

## Stellar Sample Transaction: [(Test)](https://api.rango.exchange/basic/swap?from=STELLAR.XLM\&to=STELLAR.USDC--USDC-GA5ZSEJYB37JRC5AVCIA5MOP4RHTM335X2KGX3IHOJAPP5RE34K4KZVN\&amount=50000000)
In order to execute a transaction on stellar network, Rango provides you a base64 encoded External Data Representation or XDR for operations and memo of the transaction, and preconditions of a PreconditionsV2. You can check the [official Stellar docs regarding XDRs](https://developers.stellar.org/docs/learn/fundamentals/data-format/xdr) in Stellar Network. This value must be signed by user's wallet.
{% hint style="info" %}
**Key Notes:**
* **Trust lines:** When the destination token is not the native XLM, the API returns a trust-line precondition which must be signed and broadcasted before signing and broadcasting the swap transaction. In some of the swaps, Rango would be able to include the `ChangeTrustOperation` in the transaction itself, and so no trust-line precondition would be returned by the API.
{% endhint %}
Note that for non-native Stellar assets, user's wallet must allow a trustline for the asset in order to receive it.
