|
|
||
| # OpCode Costs Tables | ||
|
|
||
| The following tables outline the cost, in motes, for a given operation on Casper's Mainnet. If you are building for a private network or other instance of Casper, you will need to verify these costs in the associated `chainspec.toml`. | ||
|
|
||
| More information on `chainspec`s for private networks can be found [here](/operators/setup-network/chain-spec.md) | ||
|
|
||
| :::note | ||
|
|
||
| All costs in this table are in [motes](/concepts/glossary/M/#motes), not CSPR, and the corresponding chainspec is [here](https://github.com/casper-network/casper-node/blob/53dd33865c2707c29284ccc0e8485f22ddd6fbe3/resources/production/chainspec.toml#L129). | ||
