  4. Deploy to testnet (30 Oct 2020)
    Adding a lookup map and an update function to the contract using map-set; deploying to testnet using Clarity tools as well as Sandbox in testnet explorer. Issues we had:

    • Clarity Tools using buf instead of buff
    • Only buff values can be entered in Testnet Explorer
