Conclusion
Soneium is a Layer 2 blockchain developed by Sony with the goal of bringing web3 techonologies into everyday use. This article shows users how to connect their MetaMask wallets to Minato, Soneium’s testnet, where they will have a first look at Soneium while providing the chain’s developers with collective feedback from the community.
