Note, at this time Metamask only works to store and transfer TFUEL and TNT-20 tokens. It cannot be used with the THETA token for technical reasons, though this may be developed in the future. This Metamask integration is intended to facilitate interaction between Theta and Ethereum for dapp development purposes which primarily uses TFUEL and TNT-20 tokens, rather than THETA which is intended to be staked long-term to Theta nodes.
