Why Developers Should Design for Blockchain Errors
Developers often spend a lot of time designing the ideal user journey. But in blockchain applications, not every transaction goes as expected.
A wallet may reject a request, a network may become congested, or a transaction may remain pending longer than anticipated. These situations are not unusual enough to ignore.
Errors Are Part of the Experience
A vague message such as “Transaction failed” leaves users with more questions than answers. Was the transaction rejected? Did the network charge a fee? Should the user try again?
Crypto applications need error messages that explain what happened and what the user can safely do next.
For swap platforms like AviorSwap, this principle is relevant to the entire transaction journey. Clear feedback can reduce confusion and help users avoid unnecessary repeated attempts.
Better Error Handling
A strong error-handling strategy should distinguish between wallet rejection, network problems, insufficient funds, and other known failure conditions. It should also avoid promising that a transaction succeeded before confirmation is available.
These principles apply well beyond DeFi. Any application that depends on external systems benefits from designing for failure rather than treating it as an afterthought.
