What is Mantis?
Mantis comes in two versions, a fully-featured client and a desktop wallet. Mantis has been developed from the ground up and written in Scala for the Ethereum Classic (ETC) network. Created by IOHK to add robustness and variety to the ETC client range, Mantis includes optimizations and upgrades that improve network security, sustainability, and performance in the long term.
The software follows the official Ethereum Classic specification and roadmap and also implements Ethereum Classic improvement proposals (ECIPs). The ETC community has a formal process for managing ECIP changes.
These are the prerequisites for installing Mantis:
- A Java Virtual Machine (JVM) with version 1.8.x.
To check the JVM version, use
To install Java, follow these instructions. (Note that the Mantis team has not tested the product with JVM 1.9 or later versions.)
- A minimum of 4GB of memory (RAM) Additional RAM is needed for the DAG file if mining is enabled.
- 250GB of disk space to ensure fast synchronizing of the node. You will need more than that for the future growth of the chain. You should have an SSD of at least 500GB for full sync.
Decide which network to use. Mantis provides access to three networks:
etc: Ethereum Classic mainnet
mordor: Mordor testnet
sagano: Mantis testnet with additional ECIP features
The usual choice is to use the Sagano testnet until you become familiar with Mantis. You can use the Sagano faucet to get free test ETC.
Warning: the Mantis wallet has not been security audited. For now, we recommend that you do not make transactions with actual ETC when connected to the Ethereum Classic mainnet.
Client or wallet?
Your next step is choosing whether you'd like to download and use the Mantis wallet or the Mantis client.
The wallet has a friendly graphical interface, while the client is a command-line interface tool.
For more details, see the client and wallet page.
