ERC677

Basics

• From the xDai docs (1-2021):

"ERC677 is very similar to an ERC20, but includes additional functionality. We use the transferandCall functionality to enable easier bridge conversions, moving STAKE from the Ethereum Mainnet to the xDai chain and back.

For more information see the EIP677 standard."

Projects

• Used by ChainLink and the STAKE token of xDai.
