    New NFT Game 6 ngày left

    I am going to make a fantastic NFT Game Website on my own. Actually looking for a developer who has experience in building NFT Games before. Here is a NFT game "Dragonary". My brother likes this game very much, but it is desktop app and it has got a problem in its logic. I'd like to have a wonderful game. Please send me your proposals if you are interested in my project. Do not waste my time. I hope to talk with only who has understood my project and got my game's general logic. Please write down your opinion about this game on your proposal or simply append the url or video of your similar project. Will share more details via chat and will start working immediately.

    Yearn vaults allow users to deposit an underlying ERC20 token, and receive yTokens at a fixed exchange rate. Some of the underlying tokens available to deposit can be readily purchased on exchanges, however several yearn vaults take Curve LP tokens as the underlying. A usable integration with Yearn will require the ability to deposit any underlying asset into these Yearn vaults. Hence, following the Set protocol architecture, we need to develop an adapter to deposit and withdraw liquidity from Curve. Here is the specification: @blockdev/BJVjtayP5 Reference of a Uniswap V2 adapter in Set protocol contract repo: If you are interested in my job, please bid with start "Set Protocol"
