MVP Smart Contract & Backend on Polygon (UMA Protocol)

PredictPiX is a decentralized prediction market platform where all user transactions are conducted using Pi Network's native currency. Users engage with the platform through the Pi Browser, and all prediction market logic, including creation, resolution, and settlement, is powered by smart contracts deployed on the Polygon network.

We have no interest in AMMs or liquidity pools. All blockchain gas fees are paid from a dedicated wallet owned by us, which is auto-funded via a % of platform fees. Objective: We are seeking a qualified blockchain developer to: Deploy UMA's LongShortPair smart contracts and Optimistic Oracle on Polygon. Integrate smart contract calls into our existing backend. Implement backend wallet logic to pay Polygon gas fees from our owned wallet. Ensure full alignment with Pi-only frontend logic (users never interact with Polygon or MATIC).

SAlesforce Problem solving

Problem Consider the following problem: Our sales organization uses Salesforce. It also frequently uses an external system (call it “Foobar”) in which the sales reps search for specific contacts. Once they have assembled a list of contacts, they request Foobar to inject these contacts into Salesforce as Leads. Foobar uses the sales rep’s credentials via OAUTH to authenticate to Salesforce and injects the Leads via the Salesforce API. The list may be as short as one Lead or as long as several hundred Leads. Our Marketing team wants these leads to be grouped via Salesforce Campaign records. That is, all the leads injected as a list by the sales rep from Foobar in a short period should be grouped, even if they arrive in more than one batch. Instructions Please set up a Salesforce instance (a Trailhead playground or a standard developer org) where you implement this using Apex and give us access to this instance. Your code should: Respond to insertions of Leads. Recognize leads injected by Foobar based on LeadSource = “Foobar”. Whenever the sales rep requests Foobar to inject one or more leads into Salesforce, recognize that a new list is being inserted and create a new Campaign to group them. Leads inserted within a short period should be part of the same campaign. The campaign should have a name that includes the string “Foobar”, the sales rep’s name, and a representation of the time the list was injected. All the Leads in the list should be associated with the Campaign via CampaignMember records. Be covered by unit tests. Follow Apex developer best practices. As this is a proof-of-concept, you are not expected to solve all possible operational and scaling issues now. However, please note in the code why you decided to take a shortcut or how it can be addressed in the future as a TODO item for the code reviewer. You will also be asked for a plan to address these concerns in your delivered project . Decide which abstractions are essential and which can be added later to meet these time constraints. It is also perfectly acceptable to submit a partial solution. Of course, the more complete the implementation, the better the advantage over partial ones. I will need explanation for each code and also a video Q&A Session afterwards to explain the solution.

1 hr advanced training Salesforce Flow HTTP Post w/nested JSON

Hello! I am an advanced Salesforce.com consultant/Flow user/developer and require a screen-sharing Zoom training on the advanced use of the relatively new Salesforce Flow HTTP Post callout function required for a specific purpose. I have been struggling to take in a single JSON text string with a 3 level nest of JSON objects in one HTTP Post callout response to Salesforce (I.e. a list of Grandparents, Parents and Children records. I have the objects and Flow built, the HTTP Post callout and the web service responding with the JSON response successfully but somehow in the setting up of the External Service action/response sample, I am struggling to take the data in and map it so that I can create the records in Salesforce. I presume that we can create the records either with a series of progressive loops in the Flow, (but ideally we would map and use the Transform element. Is this possible and if so, would we be able to do a paid consulting hour (I am based in the UK) on my Zoom account to show me how to do it? I believe that the solution lies in some error in the Apex defined variables used in the creation of the external service. Please only reply if: - you fully understand the requirements and how to solve this issue (I am confident in building Flows and using HTTP callouts. I am not looking for general training on this - it is the multi-nested response and Apex record variable callout response specific help needed. If you don't know the answer, the hour session will not be enough for a trial and error approach. I have done this already and gone round in circles :-) - You can solve the issue in Flow only. I am not looking for a suggestion of an alternative Apex only solution - We can hold the Zoom screen share session in English The solution to this I think should be able to be delivered in 20 minutes, so if we can do that, I am happy to end the session right there and complete the project and payment. I will have prepared the org, data and Flow and will these ready for us to jump straight in, so having described the requirement above, will be expecting us to jump straight into the solution (there is only 2 fields to map - Name and Age) in the Grandparent, Parent, Child schema. Thanks and look forward to hearing back! Will
