I would like to migrate an existing project from Terra to Solana to take advantage of the Solana's speed and low transaction fees. The current project on Terra is named Mirror Protocol and can be found at https://mirrorprotocol.app. The Solana version would ideally be extremely similar to the existing dApp. This will allow the reuse of code and documentation. However, the smart contacts will have to be implemented as programs on Solana. Fortunately, both blockchains use the rust language so that should make porting a bit easier. The Mirror Protocol project is opensource and code can be found on github ().

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"
I need to integrate a live-auction type interface into a website. The website would be streaming whatever item is for sale, users would be able to bid on that item while it is displayed, for a set time limit (15, 30, 45, 60 seconds, so on). Would be able to allow time to be added as bids are added, or sudden death mode. The users would have already entered their payment methods and would be charged upon completion of the auction. Would like it to be as simple as possible, with the ability to add more streamers with their own selling profiles. Would need to create a database for users, as well. This would potentially be embedded into a squarespace website, but if an overhaul is necessary for this to work smoothly, I'm game. I would also be interested in developing this int...
