Yearn Web Engineering Report

Week of 14 March 2022

Summary💌

A particular win this week is getting our partner tracking setup on the front end and SDK. This will help us figure out which services are being utilized most (ledger, shapeshift, etc) so we can start to bring in more features specific to our partners and get a better idea of which partners are being utilized by the community. We also had some nice visual fixes this week: fixing the toggle switch to clearly indicate if it is on or off, and a new vault broke our UI with the amount of 0’s it passed into the front end (speaking of which, Curve’s Rocket Pool is now live on Yearn.) Shout out to our dev’s who, late at night on a weekend, make some quick changes to get the site looking clean again.
