Create an individual RPC URL for Metamask Communication
In recent years, the growth of decentralized financing (DEFI) and non-blurred tokens (NFTS) has led to the development of various blockchain-based platforms, including EThereum (ETH) and its compatible side platforms. One of these platforms is Metamask, a popular web wallet that allows users to contact Ethereum accounts on multiple blockchain networks.
When using Metamask for communication, problems may arise when a secure and reliable relationship is established with other compatible wallets or protocols. This is where individual RPC (remote procedural call) URLs are useful. In this article, we examine how to create a unique RPC URL for metamask communication and what to know about the compatibility specification of Ethereum Virtual Machine (EVM).
What is RPC URL?
RPC URL is a unique ID that allows customers (such as wallets or applications) to establish a connection with a remote server. In the context of blockchain, the RPC URLs generally point to a node (remote procedure -call server) that provides access to the defined functionality of the Ethereum blockchain.
In the case of Metamask, the RPC URL can be used for various purposes, including the following:
1.
- Transaction Verification : Verification and Validity of Transactions using Individual RPC URL.
- Invitation of an intelligent contract
: Call smart contracts installed on the Ethereum blockchain.
EVM Compatibility Specification
The EVM (Ethereum virtual machine) specification is determined by how to identify and solve RPC URL with a particular Ethereum-compatible network such as Ethereum mainnet or Ropsten Testnet.
To determine what EVM compatibility is expected for the individual RPC URL, then:
- Check the IP node : Identify the Public IP address of the node server.
- Determine the EVM version
: Check the Ethereum Network version (such as 1.0, 1.1 or 1.2) and the supported EVM versions of each version.
Here’s an example of how to use Ethereum EVM specification to produce an RPC URL:
`Bash
Npx ehtool-pete-eth-addr
`
Replace the version you want to query (for example 1.0, 1.1 or 1.2).
Create individual RPC URL to Metamask
Once you have defined the individual RPC URL EVM compatibility specification, follow these steps:
- Make an RPC URL : Use a directory like "ETH-RPC" to produce an RPC URL that points to the node server with the right EVM version.
- Create a proxyt : Set a proxy server (for example using Nginx or API API Gateway) that transmits Metamask requests to the individual RPC URL.
Here's an example of how to create a simple proxy using Nginx:
nginx
server {
Listen 8545;
Place /rpc {
proxy_pass http: // localhost: 8080;
proxy_http_version 1.1;
Proxy_set_header update $ http_upgrade;
proxy_set_header connection 'update';
proxy_set_header host $ host;
proxy_cache_bypass $ http_upgrade;
}
}
Replace “Localhost: 8080” for the node server port number and IP address.
Conclusion
Create an individual RPC URL for metamask communication requires knowledge of the EVM compatibility specification and the knowledge needed to produce and configure the RPC URL. By following these steps, you can ensure smooth communication between wallets and other compatible wallets or protocols.
Remember to keep your unique RPC URLs safe and up to date to avoid possible vulnerabilities. Happy Blockchain Travel!
