ERC20 Mintable Token

An ERC20 token contract keeps track of fungible tokens. Any single token is equal to any other token; no token have special rights or associated behaviors. This makes ERC20 tokens useful for things like a medium of exchange, currency, voting rights, staking, and more.

See this repository for a guide on how to mint ERC20 tokens on the Telos network. ERC20 Mintable.
