Use try/catch statements when interacting with external applications

[gabririgo]

Summary

Use try/catch statements when interacting with external applications to avoid silent reverts without using assembly.

Motivation

To reduce the use of inline assembly and catch errors in the underlying call.

Specification

TBD.

Notice: Sometimes we read from an external contract with staticcall to ensure we cannot execute write operations. Using a try/catch statement will not always be possible in these instances.

Rationale

TBD.
