Common Issues when interacting with OpShin

RecursionError: maximum recursion depth exceeded

This may happen when your contract is too large. Try setting the flag --recursion-limit to something high like 2000. If it does not go away even with values above i.e. 10000, please open an issue.

The contract is too large to submit in a transaction

OpShin provides various optimizations to decrease contract size. Most of these are already activated by default but a number of powerful optimizations can be added:

• -fdeduplicate is a powerful optimization that can reduce contract size significantly. It deduplicates low level terms, but is expensive, which is why it is disabled by default.
• -O3 enables a range of powerful optimizations (including -fdeduplicate) but also removes all error traces and print statements. This significantly reduces contract size but makes debugging much more difficult.
