1. Validate eligibility for token rewards for Cashtab users
2. Send token rewards to Cashtab users (eligibility will be reset after a certain time. token rewards can only be claimed by hitting an endpoint exposed by this server from https://cashtab.com)
3. Potential future token issuance use cases, e.g. alias tokens as NFTs
Initialize with mocha, CI integration, eslint, and README.
