## Exception state
|
|
- Type: Informational
|

- Function name: `_function_0x57d4021b`

- PC address: 1653

|
### Description
|
|
A reachable exception (opcode 0xfe) has been detected. This can be caused by type errors, division by zero, out-of-bounds array access, or assert violations. This is acceptable in most situations. Note however that assert() should only be used to check invariants. Use require() for regular input checking.
