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 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.

The Komodo DeFi Framework API 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

Many examples of activation commands are available at kmd.stats.io

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 API by using the enable method, though some additional configuration is required. The Komodo DeFi Framework API requires the following options to be added to the native chain's .conf file.

logevents=1
txindex=1
addressindex=1

The Komodo DeFi Framework API 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 API 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 is 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) & ERC20 tokens
Binance Coin (BNB) & BEP20 tokens
QTUM & QRC20 tokens
Polygon (MATIC) & PLG20 tokens
Harmony (ONE) & HRC20 tokens
Fantom (FTM) & FTM20 tokens
Avalanche (AVAX) & AVX20 tokens
Moonriver (MOVR) & MVR20 tokens
And more!

Electrum Method

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

required_confirmations	integer (optional, defaults to `3`)	Number of confirmations for the Komodo DeFi Framework API to wait during the transaction steps of an atomic swap.
requires_notarization	boolean (optional, defaults to `false`)	If `true`, coins protected by Komodo Platform's dPoW security will wait for a notarization before progressing to the next atomic swap transactions step.

utxo_merge_params.max_merge_at_once	integer	Maximum number of UTXOs to merge in each consolidation transaction. Should be less that `merge_at` value, but will fail if so high the transaction becomes too large. Suggested maximum is 250.

Response

coin	string	the ticker of the enabled coin
required_confirmations	number	the number of transaction confirmations for which the Komodo DeFi Framework API must wait during the atomic swap process
mature_confirmations	number (optional)	the number of coinbase transaction confirmations required to become mature; UTXO coins only
requires_notarization	bool	whether the node must wait for a notarization of the selected coin that is performing the atomic swap transactions; applicable only for coins using Komodo dPoW

For enabling Z coins, refer to the ZHTLC activation tasks in the v2.0 Dev API.

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

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