The ERC20 token standard (https://eips.ethereum.org/EIPS/eip-20) defines fungible tokens. What is NEAR's version of this?

NEAR Protocol's version of ERC standards are called NEPs ("NEAR Enhancement Proposals"). The repo is available at https://github.com/nearprotocol/NEPs (likely will move to https://github.com/near/NEPs).
The specific standard for fungible tokens, which is analogous to ERC20, is called NEP21
Edit: Reference walkthrough in the NEAR docs
For reference, the nonfungible token standard, analogous to ERC721, is NEP4
actually these are better references for fungible tokens (ERC20) which is NEP21

and a related NFTs (ERC721 or NEP4)
