I get an "ambiguous primary types or unused types" error when trying to mint an NFT requiring 2 signatures via EIP712
I modified my code to use EIP712 to require an authorized wallet to also sign in order for an NFT to be minted. I based this off of this: https://github.com/OpenZeppelin/openzeppelin-contracts/blob/7e814a3074baa921db584c180ff6e300cdec8735/contracts/token/ERC20/extensions/ERC20Permit.sol. This is an example of someone calling a smart contract containing this ERC20Permit.sol code https://github.com/Uniswap/v3-periphery/blob/main/test/shared/permit.ts. This particular ERC20Permit.sol code is designed to allow an account to approve ERC20 spend limits without spending gas fees but the same underlying mechanisms could be applied to my use case.

UNISWAP Lets You Trade Limits Now
This is not yet possible, due to known issues with the standard Uniswap v3 router. See here for more info: https://github.com/Uniswap/v3-periphery/issues/170 - and also FYI, every trade bleeds 1 wei (which is a tiny tiny amount) due to other known issues: https://github.com/Uniswap/v3-periphery/issues/5

Should I remove comments from my Smart Contract?
Uniswap sets bytecodeHash: 'none', in the compiler settings. You can try that and see if the bytecode stops changing

cool, would be nice if UNI holders would get some nft's but we'll see the criteria for that if that's the case do you mean this? https://github.com/Uniswap/uniswap-v3-periphery/issues/10

Are ERC-777 Unsafe?
ERC-777 is difficult to implement properly, due to its susceptibility to different forms of attack(opens in a new tab). It is recommended to use ERC-20 instead. This page remains as a historical archive.
- OpenZeppelin is trying to avoid paying a bounty for a vulnerability that caused $1,1B worth of assets freeze
- Security improvements of the ERC20 token standard
- Ethereums most used token standard ERC20 requires security enhancements
- The most used Ethereums token standard (ERC20) requires a security patch.
