OPBNB RPC for API connection of blockchain nodes for Web3 developmentConnect your Web3 app to opBNB blockchain

What is opBNB RPC?

opBNB RPC is a communication protocol that allows sending remote procedure calls (RPC) to blockchain nodes using the opBNB mainnet and opBNB testnet. It enables developers to interact with the blockchain and perform actions such as sending transactions, querying information, and subscribing to events via opBNB dApps, opBNB testnet bridges, opBNB faucets, and so on.

How can I use opBNB RPC to connect to a blockchain node?

In order to connect to a blockchain node using opBNB RPC, you have to establish a connection to the node's RPC endpoint. Also, opBNB test tokens can be claimed from opBNB testnet faucets. This can be done by providing the node's hostname or IP address, along with the appropriate port number and authentication credentials if required.

Which programming languages or libraries support opBNB RPC?

opBNB (OPBNB) RPC can be integrated with dApps developed using various programming languages and libraries. Some popular options include Solidity, Python, and so on. These programming tools provide convenient interfaces to interact with the blockchain using opBNB L2 RPC.

What are some common opBNB RPC methods?

opBNB (OPBNB) RPC offers a range of methods to interact with the blockchain. Some common methods include eth_blockNumber to return the number of the most recent block, eth_getBalance to return the balance of the account of given address, and eth_getBlockByHash to return information about a block by hash. You can refer to the opBNB network RPC documentation for a comprehensive list of available methods.

What are the benefits of using opBNB RPC?

With the private node opBNB API, you don’t need to run self-hosted infrastructure for deploying decentralized applications on opBNB L2. Once set up, the opBNB RPC endpoint can just be integrated into the codebase of your dApp or interface of your on-chain wallet.

Can using opBNB RPC guarantee that I will always pay lower gas fees?

Technically, it can because opBNB is a second-later solution and it saves the computation resources of mainnet thus making opBNB API requests cost-efficient compared to Ethereum’s ones.
