How to Add THORChain to MetaMask
THORChain (RUNE) is not supported by MetaMask because it is not an Ethereum Virtual Machine (EVM) compatible blockchain. This means the network is not written in the same programming language as Ethereum called "Solidity". Instead, THORChain was built using the Cosmos SDK and Tendermint consensus engine.
This means that THORChain users and investors looking to test the network will need to use an alternative wallet that supports the RUNE ecosystem.
What is the Best THORChain MetaMask Alternative?
The best alternative for MetaMask users to interact with THORChain is the non-custodial wallet, ThorWallet. This wallet allows you to store your RUNE, swap and stake coins, view network performance metrics and more in one place. It also supports other tokens from the Cosmos ecosystem as well.
ThorWallet is a browser-based wallet accessible on desktop and mobile, making it a great option for MetaMask users wanting to experience the THORChain network. There is also an API available so developers can build applications and products that interact with the THORChain blockchain.

Is Thorwallet Safe?
Thorwallet is a non-custodial wallet, which means that the users always control their private keys. The developers of Thorwallet have also taken security measures to ensure your data and funds are safe by using cutting edge cryptography and privacy protocols.
Final Thoughts
MetaMask cannot add THORChain to its wallet due to the fact that it is not an Ethereum Virtual Machine (EVM) compatible blockchain. The best alternative for MetaMask users wanting access to THORChain is a non-custodial wallet called ThorWallet. This wallet supports RUNE, Ethereum, AVAX and other Cosmos tokens, making it a great option for those wanting to interact with the THORChain network.
