Sample transactions for all types of transactions in basic API
Overview
Here are some samples of the transaction object that is created in swap 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.
Here is the structure of an EVM transaction in the code below.
If the user does not have a sufficient approval amount for the transaction, the data for the approval transaction will be included in the approveData and approveTo fields. In this case, the user needs to sign the approval transaction first, ensure he has enough approval, and then signs the main transaction. However, if the approveData and approveTo fields are null, it indicates that the user already has enough approval for this quote and can directly sign the main transaction.
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.

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.

Here is the structure of an UTXO (Transfer) transaction:
"tx": {// This field equals to TRANSFER for all UTXO Transactions"type":"TRANSFER",// The method that should be passed to wallet including deposit, transfer"method":"transfer",// Source wallet address that can sign this transaction"fromWalletAddress":"qruy9zr8x9k335pkvqpfas3jsjfesq5gzu4nreyn4j",// Destination wallet address that the fund should be sent to"recipientAddress":"qzumtx6ufk3qu92slcsg5ajehujehzcquydmhaq0eh",// The memo of transaction, can be null"memo":"=:ETH.ETH:0x6f33bb1763eebead07cf8815a62fcd7b30311fa3:1080176077:rg:0",// The machine-readable amount of transaction"amount":"10000000000",// The decimals of the asset"decimals":8,// An asset with its ticker"asset": {"blockchain":"BCH","symbol":"BCH","address":null,"ticker":"BCH" }}
Here is the structure of a Tron transaction. Similar to EVM transactions, if user doesn't have enough approval for this quote, he needs to sign approve transaction first based on approve_payload, approve_raw_data, and approve_raw_data_hex fields and then sign the main transaction.

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.
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.)
"tx": {// This field equals to SOLANA for all SOLANA Transactions"type":"SOLANA",// Transaction blockchain"blockChain":"SOLANA",// Wallet address of transaction initiator"from":"3HsNMDtxPRUzwLpDJemmNVbasm11Ei5CGGCjktgHh27F",// Transaction identifier in case of retry"identifier":"Swap",// List of instructions"instructions": [ ],// Recent blockHash.
