In ERC777 example why are the token, recipient and sender contracts separate?

Thanks for this abcoathup. Was there a reason to split token, sender, and receive contracts?

Also, is this protocol limited to ETH? Are there any alternative chains that you may suggest to deploy?

Hi @rex,

Welcome to the community :wave:

The ERC777 example shows three types of contracts, each with their own purpose, a token that can be sent and received by other contracts, a sender contract (to send ERC777 token) and a receiver contract (that can receive ERC777 tokens).

OpenZeppelin Contracts can be used on EVM compatible blockchains. See:

This can include sidechains and Layer 2 networks. You can research which are appropriate blockchains for your use case, based on the tradeoffs of the blockchain, security considerations, development tool support and number and types of users.
