What is the difference between removing liquidity as WCTN and CTN?#
CTN is the network token for Centurion (chain ID 286). To be used like a CRC-20 token inside a pool, it must be wrapped. The wrapped version of CTN is Wrapped CTN (WCTN).
Swaps and pools on the Centurion Protocol can start and end with CTN, but during the process all CTN is wrapped into WCTN. This is because tokens must follow the CRC-20 standard to be swappable, and native CTN predates that standard.
That is why WCTN exists. WCTN is a CRC-20 token and is the accepted standard for use inside Centurion Protocol pools alongside other CRC-20 tokens.
When removing liquidity, choosing WCTN as the output token instead of CTN is more cost-efficient, because it skips the extra unwrapping step.
