An implementation of the ERC1155 token standard written entirely in Yul.

YULRC1155

A basic implementation of the ERC1155 token standard written entirely in Yul!

Yul contract: contracts/YULRC1155.yul.

Testing:

npx hardhat test test/YULRC1155.test.js

Note that the test will automatically compile the contract bytecode if it does not already exist in contracts/YULRC1155.bytecode.json.
