When creating the equillar smart-contract, one of the most important decisions was how to structure commissions. Instead of applying a single fixed percentage, we have implemented a dynamic commission system that rewards larger investments with lower rates. This approach incentivizes significant capital contributions while maintaining a fair and accessible base rate for smaller investors.
When building decentralized applications that interact with smart contracts, one of the most critical aspects is proper error handling. In Equillar, a PHP/Symfony-based platform for learning and prototyping blockchain solutions, we demonstrate an error handling strategy that bridges the gap between Rust smart contracts and a PHP backend application.
In this article, I'll explain how to manage contract errors end-to-end, from definition in Rust to user-friendly messages in PHP applications.
What you'll learn: How to implement a robust error handling system between smart contracts and web applications.
