https://github.com/Frenchkebab/ERC1155-in-pure-yul/blob/main/contracts/ERC1155.yul
Implements 100% functionally identical to ERC165, ERC1155and ERC1155MetadataURI specs including revert message only except for constructor function from ERC1155.
Automatically compiles .yul files.
npm install
npx hardhat run test/ERC1155.test
Code base is from https://github.com/OpenZeppelin/openzeppelin-contracts/tree/master/test/token/ERC1155.
Since original test scripts were using Truffle Test, test scripts in this repo are re-written using ethers and hardhat.
Test script (test/ERC1155.test.js) consists of 3 parts.
Tests all functions from IERC1155, including events and revert message.
Also checks IERC165 supportsInterface function.
Tests mint, mintBatch, burn, and burnBatch
Tests setURI function from IERC1155MetadataURI

[1] ERC1155 Behaviors
1. balanceOf
✔ reverts when queried about the zero address
1) when accounts don't own tokens
✔ returns zero before mint
2) when accounts own some tokens
✔ returns the amount of tokens owned by the given addresses
2. balanceOfBatch
✔ reverts when input arrays don't match up
✔ reverts when one of the addresses is the zero address
1) when accounts don't own tokens
✔ returns zeros for each account
2) when accounts own some tokens
✔ returns amounts owned by each account in order passed
✔ returns multiple times the balance of the same address when asked
3. setApprovalForAll
✔ sets approval status which can be queried via isApprovedForAll
✔ emits an ApprovalForAll log
✔ can unset approval for an operator
✔ reverts if attempting to approve self as an operator
4. safeTransferFrom
✔ reverts when transferring more than balance
✔ reverts when transferring to zero address
1) when called by the multiTokenHolder

✔ preserves existing balances which are not transferred by multiTokenHolder
2) when called by an operator on behalf of the multiTokenHolder
2-1) when operator is not approved by multiTokenHolder

3) when sending to a valid receiver
3-1) without data
✔ debits transferred balance from sender
✔ credits transferred balance to receiver
✔ emits a TransferSingle log

✔ credits transferred balance to receiver
✔ emits a TransferSingle log
✔ calls onERC1155Received
4) to a receiver contract returning unexpected value
✔ reverts
5) to a receiver contract that reverts
✔ should revert
6) to a contract that does not implement the required function
✔ reverts
5. safeBatchTransferFrom
✔ reverts when transferring amount more than any of balances
✔ should revert when ids array length doesn't match amounts array length
✔ reverts when transferring to zero address
1) when called by the multiTokenHolder
✔ debits transferred balances from sender
✔ credits transferred balances to receiver
✔ emits a TransferBatch log
2) when called by an operator on behalf of the multiTokenHolder
2-1) when operator is not approved by multiTokenHolder
✔ reverts
2-2) when operator is approved by multiTokenHolder

✔ emits a TransferBatch log
✔ preserves operator's balances not involved in the transfer
3) when sending to a valid receiver
3-1) without data
✔ debits transferred balances from sender
✔ credits transferred balances to receiver
✔ emits a TransferBatch log
✔ calls onERC1155BatchReceived
3-2) with data
✔ debits transferred balances from sender
✔ credits transferred balances to receiver
✔ emits a TransferBatch log
✔ calls onERC1155Received
4) to a receiver contract returning unexpected value
✔ reverts
5) to a receiver contract that reverts
✔ reverts
6) to a receiver contract that reverts only on single transfers
✔ debits transferred balances from sender
✔ credits transferred balances to receiver
✔ emits a TransferBatch log
✔ calls onERC1155BatchReceived
7) to a contract that does not implement the required function
✔ reverts
ERC165
✔ supportsInterface uses less than 30k gas
✔ all interfaces are reported as supported
[2] internal functions
1. _mint
✔ reverts with a zero destination address
