Ether Pool

By default, each Kaleido environment is configured with one billion ether in the chain’s genesis block. The pool offers a convenient alternative to developing your own ERC20 token and can be used in myriad ways. For example, it can be used to enforce optional gas costs for executing smart contract methods and/or to represent a fungible and transactional asset. The ether pool is an environmentally-shared utility service, with the balance defaulting to the system monitor's sole Ethereum account, and is accessible by any organization operating a node within the environment.

NOTE: Kaleido also offers support for environment creation with pre-funded accounts. See the Advanced Blockchain Configuration documentation and/or the /environments API Documentation for more details on pre-funded accounts.

The governance of the pool is left entirely to the discretion of the consortium. For example, the pool can be used intermittently on a need-by-need basis or drained immediately and then disseminated in accordance with some agreed upon protocol. Kaleido enforces no restrictions on its usage within the permissioned Ethereum orchestration.

Fund an Account

The ether can be accessed directly via the Kaleido user interface or through an administrative /fundaccount API call. This documentation will focus on interaction via the Kaleido console. Please refer to the /environments API Documentation for details on the programmatic approach.

Accessing via the Console
