 There a few core contracts that implement the behavior specified in the EIP:
 
 * {IERC20}: the interface all ERC20 implementations should conform to.
-* {IERC20Metadata}: the extended ERC20 interface including the <<ERC20-name,`name`>>, <<ERC20-symbol,`symbol`>> and <<ERC20-decimals,`decimals`>> functions.

 Additionally there are multiple custom extensions, including:
