# Constant Presets
|
|
|
|
|
|
|
|
|
|
This directory contains a set of constants presets used for testing, testnets, and mainnet.
|
|
|
|
|
|
|
|
|
|
A preset file contains all the constants known for its target.
|
|
|
|
|
Later-fork constants can be ignored, e.g. ignore phase1 constants as a client that only supports phase 0 currently.
