Coin Activation

There are two methods of coin activation:

• enable - Connects to a native daemon, or a url which handles RPCs for Platform coins (e.g. ETH, MATIC, FTM, BNB, ONE)
• electrum - Connects to an electrum server (opens new window) for UTXO based coins and QTUM/QRC20 tokens.

A coin can only be activated once per session, and must be activated before it can be used in trading or wallet functions.

Important

The Komodo DeFi Framework requires an mm2 parameter to be set for each coin. This can be added to the enable/electrum command, or defined in your coins file.

The value of the mm2 parameter informs the software as to whether the coin is expected to be compatible for atomic swaps.

• 0 = non-compatible
• 1 = compatible

TIP

Many examples of activation commands are available at kmd.stats.io (opens new window)

Native mode activation

If you are running a UTXO based coin daemon locally and the blockchain is synchronised, you can connect the local daemon to the Komodo DeFi Framework by using the enable method, though some additional configuration is required. The Komodo DeFi Framework requires the following options to be added to the native chain's .conf file (opens new window).

logevents=1
txindex=1
addressindex=1

Note

The Komodo DeFi Framework node's coin address needs to be imported manually into the coin daemon using the importaddress method.

Lite mode activation

Activating coins in 'lite mode' means you don't need to have a native coin daemon installed, or keep a local blockchain synchronised. In this mode, the Komodo DeFi Framework communicates with an external node to perform transactions and query the blockchain. UTXO based coins and QTUM/QRC20 tokens communicate via electrum servers, while other platform coins communicate via JSON RPC urls.

Komodo DeFi Framework provides a true cross chain, cross protocol Decentralized Exchange (DEX), allowing for trades between coins and tokens across many platforms and ecosystems, such as:

• UTXO based coins (e.g. DOGE, BTC, ZEC, LTC, DASH, DGB)
• Ethereum (ETH) (opens new window) & ERC20 tokens (opens new window)
• Binance Coin (BNB) (opens new window) & BEP20 (opens new window) tokens
• QTUM (opens new window) & QRC20 tokens (opens new window)
• Polygon (MATIC) (opens new window) & PLG20 tokens (opens new window)
• Harmony (ONE) (opens new window) & HRC20 tokens (opens new window)
• Fantom (FTM) (opens new window) & FTM20 tokens (opens new window)
• Avalanche (AVAX) (opens new window) & AVX20 tokens (opens new window)
• Moonriver (MOVR) (opens new window) & MVR20 tokens (opens new window)
• And more!

Electrum

TIP

Electrum mode is only available for UTXO based coins and QTUM/QRC20 tokens.

Enable

Arguments

Structure	Type	Description

gas_station_url	string (optional for ETH/ERC20 and other gas model chains)	url of ETH gas station API (opens new window); The Komodo DeFi Framework uses eth_gasPrice RPC API (opens new window) by default; when this parameter is set, the Komodo DeFi Framework will request the current gas price from Station for new transactions, and this often results in lower fees
gas_station_decimals	integer (optional for ETH/ERC20 and other gas model chains)	Defines the decimals used to denominate the gas station response to gwei units.

gas_station_policy.policy	string (optional for ETH/ERC20 and other gas model chains)	Defines the method of gas price calculation from the station response. "MeanAverageFast" will use the mean between average and fast fields. "Average" will return a simple average value. Defaults to "MeanAverageFast".

To see more examples for other platforms like Fantom, Avalanche & Harmony, you can search the Komodo DeFi Framework Coin Activation Commands List (opens new window) or build a single batch command to enable a set of selected coins via the Batch Coin Activation Form (opens new window)

We welcome volunteers to test new coins for Komodo DeFi Framework compatibility! Follow the Submitting Coin Test Results guide (opens new window) for more information, or drop into the Komodo Platform Discord Server (opens new window) for a chat if you need some help.
