    What is the XDC Network?

    The XDC is an open-source enterprise-grade blockchain network, designed by decentralized smart contracts platform XinFin. The XDC Network is an EVM-compatible Layer 1 blockchain, that offers a solid foundation on which any project can build. Anything that can be built on Ethereum or other EVM Layer 1s can also be built on XDC with ease, super-sonic speed, and negligible gas fees.

    XDC Network uses the Delegated Proof-of-Stake consensus mechanism. It is known as XDPoS. It enables leveraging the power of stakeholders to resolve consensus issues fairly and democratically. Due to its unique features, XDPoS is more enterprise-ready and regulatory-compliant than other blockchains. 

    XDC Network serves as the backbone for many unique enterprise applications such as ISO 20022 messaging and those designed to support global trade. Its compatibility with ISO 20022 messaging and legacy systems like SWIFT and ERP makes XDC a unique and outstanding blockchain. As such financial messaging protocols are similar to what we use in our daily lives while making cashless payments or sending online transactions. That is the reason why the XDC network has advantages and a great chance among other blockchains to be integrated into our daily lives, allowing users and enterprises to make the process of Real-World Asset tokenization as easy as possible.

    What is RWA in the Context of Blockchain?

    In the blockchain realm, Real World Assets (RWA) refers to tangible or intangible assets from the real world, such as real estate, commodities, or intellectual property, that are tokenized and managed on a blockchain. In simple words, any goods and things that you use in your daily life could be counted as RWA and be digitized with the help of XDC network capabilities. 

    The Role of Smart Contracts in RWA Tokenization

    Smart contracts play a pivotal role in this process, serving as self-executing contracts with the terms of the agreement directly written into code. These contracts automate the execution of transactions and agreements, providing a secure and efficient way to manage RWAs on the blockchain. 

    The principles of smart contracts utilization could be translated on such an easy example: if you’re making a bet with your friend for $100 that the LA Lakers will win the next NBA tournament, you could certify this bet with a smart contract. That way, when the conditions are satisfied and the Lakers are the winners, your friend’s hundred bucks will be automatically sent to your bank account. 

    That was just one of hundreds of billions of examples of utilizing smart contracts. The point is that any real-world asset could be tokenized and recorded on the blockchain. With the tokenized Real World Assets recorded on the blockchain via smart contracts, you could also sell your car, a rare Pokemon card, or even intellectual property for the song that you’ve just written and much much more. Be sure that the XDC network is a perfect tool for you in these cases!

    RPC Methods for Interacting with RWA Smart Contracts on XDC Network

    To interact with smart contracts that you’ve created or with pre-build ones that you’re willing to use, you need to utilize some JSON RPC methods. Keeping in mind that XDC is EVM compatible Layer 1 network, all the RPC methods available on Ethereum can be used on the XDC network too. 

    So, once your contract is deployed, you’ll interact with it using its functions to manage the RWAs. Interacting with RWA smart contracts on the XDC Network involves two primary JSON RPC methods: 

    • eth_sendRawTransaction
      • for executing transactions that alter the blockchain state
    • eth_call
      • for reading data from the blockchain without making any changes. 

    These methods facilitate various operations such as transferring asset ownership, updating asset information, and querying asset details.

    Before we delve into these methods in detail and show you some sample requests, there is one crucial requirement that allows you to interact with the XDC network – accessing XDC RPC Full Nodes! There are a few ways to do this: 

    • By running your own XDC full nodes

    XDC eth_sendRawTransaction JSON RPC Method

    The eth_sendRawTransaction method is crucial for submitting transactions that modify the state of the blockchain. This includes operations like transferring RWA ownership or executing specific functions within a smart contract. The method requires a signed transaction as input, ensuring secure authorization of the operation. 

    Here’s the sample request for the eth_sendRawTransaction RPC method: 

    curl --location '<your-api-key>' \
    --header 'Content-Type: application/json' \
    --data '{
        "jsonrpc": "2.0",
        "method": "eth_sendRawTransaction",
        "params": [
        "id": 1

    The response for this method is the transaction hash, or the zero hash if the transaction is not yet available. Don’t forget to add your API key and replace <Signed_transaction> with the actual hash of your signed transaction. Everything has to be formatted correctly in order for things to work. So, make sure your nonce contains the 0x prefix. <Signed_transaction> should include a call to your contract’s function to be able to communicate with the RWA smart contract.

    XDC eth_call JSON RPC Method

    For operations that require reading data from the blockchain without making any state changes, the eth_call method is used. This method is instrumental in querying smart contract functions to retrieve information about RWAs, such as current ownership, asset status, and other relevant details. It’s a powerful tool for applications that need to display real-time asset information without executing transactions. 

    Here’s a sample request: 

    curl --location '<your api-key>' \
    --header 'Content-Type: application/json' \
    --data '{
        "jsonrpc": "2.0",
        "method": "eth_call",
        "params": [
                "from":"<The address the transaction is sent from (string)>",
                "to":"<The address to which the transaction is addressed (string)>",
                "gas":"<gas provided for the transaction execution (integer)>",
                "gasPrice":"<each paid gas encoded as hexadecimal (integer) >",
                "value":"<value of transaction encoded as hexadecimal (integer)>",
                "data":"<The hash of the method signature and encoded parameters (string)>"
        "id": 1

    eth_call RPC method returns the data value of the executed contract function. There are lots of parameters for this method. Some of them are optional and some of them are required (such as “to” and “data”). In the case of managing RWA data, the parameter “to” is your RWA’s smart contract address.


    Interacting with XDC Network using JSON RPC in terms of Real World Assets management provides a blend of security, efficiency, and scalability. This guide has outlined the essential steps and methods for interacting with RWA smart contracts, providing a clear path for Web3 developers and enterprises to leverage the power of blockchain for real-world asset management.
