Similar to what we did for Uniswap V2 on how to find address of smart contract pool that will be generated we can do the same for V3 https://mirror.xyz/n00b21337.eth/0QkNt3NnLnnUSy4jFmWnaeRr_38Z3wlYKKf1O6URG3c Depending on what chain we are at, you can find all the addresses of Factories here https://github.com/Uniswap/sdk-core/blob/5365ae4cd021ab53b94b0879ec6ceb6ad3ebdce9/src/addresses.ts#L135 Aim for the v3CoreFactoryAddress values.**So there are a few methods to do that, one could be to us...

EIP 4096 has an interesting method of updating your metadata with events, more details here. https://eips.ethereum.org/EIPS/eip-4906 So lets see how to implement it with an example. First you need to create a file with interface that has this code in itpragma solidity ^0.8.0; import "@openzeppelin/contracts/utils/introspection/IERC165.sol"; /// @title EIP-721 Metadata Update Extension interface IERC4906 is IERC165 { /// @dev This event emits when the metadata of a token is changed. /// Third-...

I wanted to have one setter for array so I can just pass the variable to it and push the element to proper array, way to do this would be to have one internal function and one public that gets the element and chooses proper array.
string[] public goalkeeepr = []
string[] public left_back = []
.......
function addPlayer(string memory position, string memory name) public {
if (keccak256(bytes(position)) == keccak256(bytes("GK"))) {
addToArray(goalkeeepr, name);
}
else if (keccak256(bytes(position)) == keccak256(bytes("LB"))) {
addToArray(left_back, name);
}
}
function addToArray(string[] storage ar, string memory x) internal {
ar.push(x);
}
