Everscale/Venom Console Usage

This tool serves the purpose of generating election requests for the Rust Node. The tool is compatible with TONOS-CLI and allows to perform all actions necessary to obtain a signed election request.

How to use

console -C console.json -c "commamd with parameters" -c "another command" -t timeout

Where

console.json - path to configuration file

commamd with parameters/ another command – any of the supported console commands with necessary parameters

timeout – command timeout in seconds

Configuration file should be created manually and have the following format:

{
		"config": {
				"server_address": "127.0.0.1:4924",
				"server_key": {
						"type_id": 1209251014,
						"pub_key": "cujCRU4rQbSw48yHVHxQtRPhUlbo+BuZggFTQSu04Y8="
				},
				"client_key": {
						"type_id": 1209251014,
						"pvt_key": "oEivbTDjSOSCgooUM0DAS2z2hIdnLw/PT82A/OFLDmA="
				}
		},
		"wallet_id": "-1:af17db43f40b6aa24e7203a9f8c8652310c88c125062d1129fe883eaa1bd6763",
		"max_factor": 2.7
}

Where

server_address – address and port of the node.

server_key – structure containing server public key. Can be generated with keygen tool.

client_key – structure containing client private key. Can be generated with keygen tool.

type_id – key type, indicating ed25519 is used. Should not be changed.

wallet_id – validator wallet address.

max_factor – max_factor stake parameter (maximum ratio allowed between your stake and the minimal validator stake in the elected validator group), should be ≥ 1
