Inspiration

The internet has always been a noisy place, plagued with self portrayed traders and investors. More than often, the loudest noise on social media pieces are those which jump on the bandwagon, exaggerating the trajectory of the current market trend, or those that strongly oppose the popular view for the sake of appeasing the contrarians.

Amidst the noise, it is also the space to learn and gain insights from actual experts and upcoming thought leaders who share their knowledge.

In the space of financial advice and trading, it is especially difficult to identify which individuals are these as single large wins could be purely out of luck. To identify a good trader, there is a need to prove both consistency and accuracy of market predictions.

And a screenshot of a robinhood trading history just isn't going to cut it!

What it does

Glyph is a twitter bot that pushes real-time crypto and stock prediction claims on twitter onto the polygon blockchain and IPFS. Glyph smart contract record and evaluate the prediction outcome using Chainlink Price Feeds and Chainlink Automation. With Glyph, a trader can build a verifiable track record on the blockchain. And individuals can quickly identify consistent and accurate traders on twitter. Glyph is live (for testing) on Polygon Test Net and twitter.

Making a prediction

Make a prediction by mentioning the bot,
for example
"@fortheglyph LONG ETH 4M" - long ethereum for 4 months
"@fortheglyph SHORT SAND 5D" - short sand token for 5 days

Position: LONG, SHORT
Available symbols on testnet: BTC, ETH, LINK, MATIC, SAND, EUR
Time Units: H - Hour, D - Day, M - Month, Y - Year

The bot will parse your prediction and push it onto the polygon blockchain and respond with a confirmation

Prediction Evaluation

When it is time to evaluate your prediction, e.g after 4 months, the bot will reply to the tweet. All outcomes are stored on the blockchain and it's logs.

How we built it

Blockchain Components (Solidity + Truffle)

PriceFeedManager Smart Contract - manages all available symbols and chainlink aggregator addresses to query latest price from
PredictionManager Smart Contract - manages all registered user and prediction related data. Implements AutomationCompatible.
Chainlink Price Feed - Get reliable latest price for symbols
Chainlink Automation - Runs checkUpkeep on PredictionManager to evaluate if prediction is ready to be evaluated

Backend Server (Flask)

Listens to twitter events via webhook
Caches blockchain event data to be readily queried by app
Provide utility api endpoints such as twitter id look up during registration

Frontend (Vue, Nuxt)

Create registration page, integrated with backend server

Accomplishments that we're proud of

Designed PriceFeedManager which easily scales to support all symbols from chainlink when deploying to mainnet
Created a large number of unit tests for smart contract which allowed continuous integration
First time working with: solidity, ipfs, vue3, twitter webhooks, truffle, mocha, chai
