eStandard Digital Token (ESDT) is a general standard token of the MultiversX blockchain platform (MultiversX's version of ERC20), embedded in the protocol, that allows people to issue their own tokens using network advantages: fast, inexpensive to mint (0.05 eGLD) & transfer (0.00005 eGLD).
MEX, wUSDC & RIDE are some of the first ESDTs with use cases on the network.
