Efficiency Upgrade

We're always looking for ways to improve efficiency and reduce trading costs. That's why we upgraded our price oracles: with the previous Pyth version, we needed 10 transactions costing 0.05 ALGOs each time we checked account health during settlement. Now, thanks to the new Pyth version, we accomplish the same with just 2 transactions, costing a total of 0.018 ALGOs!

In conclusion, the recent rollout of the third update to C3.io's Testnet marks a significant step forward in enhancing the platform's performance, security, and user experience. Thank you for being part of this journey with us!
