Errors structure

In Fluid, errors are organized systematically to enhance clarity and ease of reference. Each protocol or module within a protocol has its dedicated set of error definitions and types.

Error IDs Specification

To maintain consistency and avoid clashes, we follow a unique numbering system for error IDs. Each protocol or even each contract within a protocol gets a distinct range.

For instance:

• Liquidity Protocol:
  • Liquidity UserModule module: 10001, 10002, 10003, etc.
  • Liquidity AdminModule module: 11001, 11002, 11003, etc.
• Lending Protocol:
  • Lending fToken module: 20001, 20002, 20003, etc.
  • Lending LendingFactory module: 21001, 21002, etc.

By adhering to this structure, developers can easily trace errors back to their source module and protocol, simplifying debugging and maintenance.
