The new version of the smart contracts which power this platform are almost ready to go live. One of the new features they enable is Meta Transactions: the ability for a relayer to submit signed messages on a user's behalf, and then submit them as new transactions for on-chain processing. For more information, see this blog post.
The new version of our smart contracts allow for the use of meta-transactions, which would mean that users aren't required to pay gas for every single action they'd like to take. For this bounty, I would like for you to create a stand-alone node js application which will receive these signed messages and submit the transactions to the main chain.
metaFulfillBountyfunction, the app would receive a request which includes the signature, bounty ID, array of fulfillers, data string, and nonce, along with the address which triggered it.
When you have completed this project, please create a private repo which hosts the project, and invite me (@mbeylin) to it so I may review the code and make suggestions.
This is a big bounty, which may require some iteration as we scope out the solution and test it. Please be prepared to be communicative with me, and I am very happy to help you along the way.
