    What is ZetaChain?<\/strong><\/h2>\n\n\n

    Zetachain<\/strong><\/a> is a Simple, Fast, and Secure Omnichain Blockchain.<\/strong> It is a decentralized blockchain protocol that allows for seamless communication and interaction between different blockchain networks. <\/p>\n\n\n\n

    ZetaChain is the first ever L1 blockchain to enable fully interoperable smart contracts, or omnichain smart contracts, that connect all blockchains and bring the power of programmability to non-smart contract chains like Bitcoin<\/strong> and Dogecoin<\/strong>. <\/p>\n\n\n\n

    Whether you’re dealing with Ethereum, Binance Smart Chain, Polygon, Cosmos,<\/strong> or any other network, ZetaChain’s architecture facilitates seamless communications and transactions.  It provides an unparalleled combination of security, simplicity, and flexibility for developers. ZetaChain stands as the bridge that connects isolated islands in the borderless ocean of blockchains, enabling developers to build truly innovative web3 applications.<\/p>\n\n\n\n

    By accessing ZetaChain Mainnet RPC for EVM and Cosmos REST, developers and businesses can work with on-chain data, send requests, and connect to the blockchains to send transactions and messages in ZetaChain, ensuring the highest level of safety, stability, and transaction speed.<\/p>\n\n\n\n

    Before we dive into the core of this article and explore the variety of RPC API methods ZetaChain offers, it’s essential to handle a necessary primal step:  access ZetaChain RPC full nodes. You have two primary options for connecting to the ZetaChain network:<\/p>\n\n\n\n

      \n
    1. Setting up your own ZetaChain node.<\/li>\n\n\n\n
    2. Utilizing services from third-party node providers like NOWNodes.<\/li>\n<\/ol>\n\n\n\n

      Given that the first option demands significant time, resources, and financial investment, we strongly recommend you use node providers such as NOWNodes. Our Blockchain-as-a-Service solution, offering access to ZetaChain Full Nodes, is made to economize on your time and finances. It spares you the complexity and responsibility of managing your own nodes, especially when unnecessary. <\/p>\n\n\n\n

      Wish to get started with a ZetaChain full node today and experience the full power of the ecosystem? Of course, you are! Here\u2019s a simple step-by-step guide on how to do so: <\/p>\n\n\n\n

        \n
      1. Visit the NOWNodes website (nownodes.io<\/a>) and sign up for an account<\/a> using only your email address and a password. <\/li>\n\n\n\n
      2. Choose a tariff plan<\/a> that fits your web3 development needs.<\/li>\n\n\n\n
      3. With a START FREE plan, you can only access 5 blockchain networks. So, choose ZetaChain mainnet and other blockchains that you wish to connect to. <\/li>\n\n\n\n
      4. On the \u201cDASHBOARD<\/strong>\u201d page find the \u201cADD API KEY<\/strong>\u201d button and generate your API key.<\/li>\n\n\n\n
      5. Finally, when the registration process is complete, it\u2019s time to make some requests! Use the provided endpoint (eg. zetachain.nownodes.io for ZetaChain mainnet full node) and your API key to make it happen.<\/li>\n<\/ol>\n\n\n\n

        If you wish to work with the ZetaChain Tendermint  RPC node interface, it is only available in the PRO<\/strong> plan and higher.<\/p>\n\n\n\n

        There are various subscription plans suitable for different development needs. Whether you\u2019re a beginner, you could use our START FREE <\/strong>plan, or you\u2019re an Enterprise owner \u2013 we have an ENTERPRISE<\/strong> plan for you, offering 100 MILLION requests\/month<\/a><\/div>\n\n\n

        How to Interact with ZetaChain RPC Full Node<\/strong><\/h2>\n\n\n

        ZetaChain provides a robust set of API methods that developers can utilize to interact with the network. By connecting to the ZetaChain network with NOWNodes you can utilize EVM RPC API, Cosmos REST API, Tendermint RPC, and many other methods available on ZetaChain. Let’s take a closer look at some of the key ZetaChain RPC API methods:<\/p>\n\n\n

        ZetaChain EVM RPC Methods<\/h3>\n\n\n

        As said, ZetaChain is  Ethereum\u2019s Layer 1 blockchain, which means that it\u2019s compatible with EVM and supports the same methods as used on Ethereum’s main network. For those entrenched in the Ethereum or EVM-compatible universe, ZetaChain’s EVM RPC methods are a godsend. These methods enable you to execute smart contracts, transfer tokens, and interact with the blockchain in familiar ways. <\/p>\n\n\n\n

        To use ETH methods on Zetachain you should use zetachain-evm.nownodes.io<\/code> endpoint. Now let\u2019s take a look at some of the basic methods of EVM like eth_blockNumber<\/code>, which returns the current latest block number. Here\u2019s the sample request: <\/p>\n\n\n\n

        https://zetachain-evm.nownodes.io\/<api-key>\n--header 'Content-Type: application\/json' \\\n--data '{\n\t\"jsonrpc\": \"2.0\",\n\t\"method\": \"eth_blockNumber\",\n\t\"params\": [],\n\t\"id\": 1\n}<\/code><\/pre>\n\n\n\n
        The response will be a hexadecimal of an integer representing the current block number the client is on. Here\u2019s the sample response: <\/p>\n\n\n\n
        {\n\t\"jsonrpc\": \"2.0\",\n\t\"id\": 1,\n\t\"result\": \"0x1e1708\"\n}<\/code><\/pre>\n\n\n\n
        To explore more ETH methods available on ZetaChain you can visit NOWNodes official documentation<\/a>. <\/p>\n\n\n
        ZetaChain Cosmos REST API Methods<\/h3>\n\n\n
        ZetaChain is a decentralized and public blockchain network that is built on Cosmos SDK and Tendermint Consensus. This Blockchain is designed to offer interoperability and connectivity across multiple blockchain networks. Its cross-chain interoperability is made possible by its Cosmos SDK origin. Cosmos REST API allows ZetaChain users to retrieve token balances from different networks, stake coins, query different types of information (such as Accounts and Validators data), and much more.  <\/p>\n\n\n\n
        To use Cosmos HTTP API methods utilize the provided basic zetachain.nownodes.io<\/code> endpoint and your API key. Let\u2019s take a look at the \/params<\/code> method which is being used to query the current authentication (auth) module parameters. This endpoint plays a crucial role in retrieving configurations that dictate how aspects such as account management and fee handling are managed within the blockchain network. Here\u2019s an example of how you can make a request with this endpoint: <\/p>\n\n\n\n
        curl --request GET \\\n  --url https:\/\/zetachain.nownodes.io\/cosmos\/auth\/v1beta1\/params \\\n--header 'Accept: *\/*' \\\n--header 'api-key: <your_api-key>'<\/code><\/pre>\n\n\n\n
        This endpoint queries all the available parameters. Here\u2019s the sample response: <\/p>\n\n\n\n
        {\n\t\"params\": {\n\t\t\"max_memo_characters\": \"256\",\n\t\t\"tx_sig_limit\": \"7\",\n\t\t\"tx_size_cost_per_byte\": \"10\",\n\t\t\"sig_verify_cost_ed25519\": \"590\",\n\t\t\"sig_verify_cost_secp256k1\": \"1000\"\n\t}\n}<\/code><\/pre>\n\n\n\n
        When you make this request, the API responds with the current set of parameters that the auth module is using. These parameters can include settings such as:<\/p>\n\n\n\n
