Ready to connect to the Metis Andromeda network and join the best community in crypto? We’ve got you covered. This week’s Tech Thursday explains how to connect a Metamask wallet to Andromeda and how RPCs work behind the scenes to enable users to interact with a blockchain network.

From user interface to dApp development and network interaction, there are a lot of moving pieces in blockchain. Quality UI/UX design makes it enjoyable and intuitive for users to navigate a dApp. Developers work tirelessly on the coding that powers their on-chain applications to ensure they work seamlessly. But then what?

How does a dApp communicate with a blockchain network?

RPCs, or Remote Procedure Calls, allow dApps to communicate with a blockchain to read data, send transactions, or interact with a smart contract. Using RPC nodes, the components of a dApp (the front end or application layer and the back end or protocol layer) can communicate with servers from any location to execute programs.

If you’ve ever checked the balance in your Metamask wallet or made a trade on a DEX, RPCs made it possible. In fact, when setting up your wallet, you have to input the RPC address for any network to which you’d like to connect. The RPC address for the Metis Andromeda network is: https://andromeda.metis.io/?owner=1088. You can find connection information for EVM networks on chainlist.org, or check out the source below for a step by step explanation of how to connect your wallet to Metis Andromeda.

RPCs are required to run a dApp on a blockchain, which means developers either need to run their own RPC node or use a service that provides them. Pokt incentivizes RPC nodes in a decentralized network to relay data between dApps and blockchains. Having a global network of nodes at your disposal makes for a speedy and reliable user experience, so dApps benefit greatly from low latency periods and consistent access to the data they need. Pokt’s network has 99.9% uptime, and now, they’re part of the Metis ecosystem. dApps who wish to connect with the Metis blockchain can use Pokt, and anyone can run an RPC node for rewards! Scalability in Web3 just got that much easier.
