Overview
Your workspace automatically uses the default Deposit Control and Confirmation Policy. Depending on the blockchain, the default policy requires the following number of confirmations.
Ethereum Classic
372 confirmations are required for all transactions made on the Ethereum Classic blockchain network. As this blockchain network is subject to a 51% risk of attack, we recommend a high amount of confirmations.
Blockchains with a finality property
The following blockchain networks have a finality property and don't rely on a variable number of confirmations. The default policy contains the correct value for these blockchain networks and can't be changed.
This means you cannot specify a custom number of confirmations for blockchain networks with a finality property. If you list and modify the value set for them, Fireblocks Support will require you to submit a revised policy that does not include these blockchain networks.
