Implemented a stacking protocol with the ability to move stacked tokens between stakings in Polygon and BSC blockchains. Staking distributes a certainnumber of tokens per day to all stackers as a reward.Stackers receive an NFT as a receipt, which storesinformation about the number of tokens they havestaked. If the user stakes for second time, the balanceinformation in the NFT is updated. A DAO was alsoimplemented to change the parameters of the platform. To participate in the DAO, you must haveNFTs issued by a smart contract of staking. Thenumber of staked tokens directly affects the weight of the vote. To transfer tokens between networks, acrosschain bridge has been written based on thevalidation of translations using the service relay andverification within the smart contracts by theecrecover function. When a steak is transferred, the balance information in the NFT is updated or the NFTitself is burned in one network and mined in the other.

Made Solidity smart-contract, using Truffle, Remix, ERC-20, ERC-721, library OpenZeppelin. Getacquainted with Ganache, Uniswap. Worked withOpenSea, designed React app that interact with locked tokens of investors on bsc and eth networks, made scripts for Vesting. Maintained cross-chainbridge, created a simple nft contracts one of them is marketplace contract. That uses mapping to contain different market items.
