Hello

Please don't send a proposal unless YOU ARE a SENIOR SOLIDITY DEVELOPER! kindly read thoroughly

I am seeking a Senior Solidity Developer with experience in cross-chain deployment, knows how to adjust non-native currency price on Polygon, upgradable smart contracts, write integration tests, and debug current existing NFT code (not collectibles).

This is a small part of a big project that can turn into a long-term commitment, in this part you are only going to debug a small piece of code and recommend upgradability & cross-chain. If I find you on the same page as me and get the required experience, you will be hired for the rest of the project.

Skills: Solidity, Smart Contracts, Blockchain
