Komodo DeFi API configuration
Komodo DeFi-API configuration parameters, along with additional runtime flags, and per-process environment variables are listed in the source code, and can be viewed by running the ./mm2 --help.
When running the Komodo DeFi API via commandline with the mm2 binary, some basic configuration parameters need to be defined in either an MM2.json file, or at runtime.
| Parameter | Type | Description |
|---|---|---|
| gui | string | Information to identify which app, tool or product is using the API, e.g. AtomicDEX iOS 1.0.1. Helps developers identify if an issue is related to specific builds or operating systems etc. |
| netid | integer | Nework ID number, telling the AtomicDEX-API which network to join. 8762 is the current main network, though alternative netids can be used for testing or "private" trades as long as seed nodes exist to support it. |
| passphrase | string | Your passphrase; this is the source of each of your coins private keys. KEEP IT SAFE! |
| rpc_password | string | For RPC requests that need authentication, this will need to match the userpass value in the request body. |
| allow_weak_password | boolean | Optional, defaults to false. If true, will allow low entropy rpc_password. If false rpc_password must not have 3 of the same characters in a row, must be between 8-32 characters in length, must contain at least one of each of the following: numeric, uppercase, lowercase, special character (e.g. !#$*). It also can not contain the word "password", or the chars <, >, or &. |
| dbdir | string | Optional, defaults to a subfolder named DB in the path of your mm2 binary. This path will store the Komodo DeFi-API database data. |
| rpcip | string | Optional, defaults to 127.0.0.1. IP address to bind to for RPC server. |
| rpcport | integer | Optional, defaults to 7783. Port to use for RPC communication. |
| rpc_local_only | boolean | Optional, defaults to true. If false the AtomicDEX API will allow rpc methods sent from external IP addresses. Warning: Only use this if you know what you are doing, and have put the appropriate security measures in place. |
| i_am_seed | boolean | Optional, defaults to false. Runs AtomicDEX API as a seed node mode (acting as a relay for AtomicDEX API clients). Use of this mode is not reccomended on the main network (8762) as it could result in a pubkey ban if non-compliant. On alternative testing or private networks, at least one seed node is required to relay information to other AtomicDEX API clients using the same netID. |
| seednodes | list of strings | Optional. If operating on a test or private netID, the IP address of at least one seed node is required (on the main network, these are already hardcoded) |
| enable_hd | boolean | Optional. If true, the Komodo DeFi-API will work in only the HD mode, and coins will need to have a coin derivation path entry in the coins file for activation. Defaults to false. |
| message_service_cfg | object | Optional. This data is used to configure Telegram messenger alerts for swap events when running using the makerbot functionality. For more information check out the telegram alerts guide |
| metrics | integer | Optional, defaults to 300. The interval in seconds which metrics are logged. Set to 0 to disable metrics. |
| prometheusport | integer | Optional. Only used if you are logging metrics in Prometheus and Grafana. For more information check out the Komodo DeFi metrics guide |
| prometheus_credentials | integer | Optional. Only used if you are logging metrics in Prometheus and Grafana with authentication. For more information check out the Komodo DeFi metrics guide |

If you are using HD wallets, you will need to add the hd_account_id value to your MM2.json file. This value will be used in the derivation path for all coins, and will take the place of the COIN_ID value in the following path: m/44'/COIN_ID'/<hd_account_id>'/CHAIN/ADDRESS_ID.
Using the same seed phrase with / without setting the hd_account_id value
will result in different addresses being generated. For example, when using
the seed phrase february soldier message acid member jump shadow walk novel impose puppy tornado: - If the hd_account_id value is set to 0 in
MM2.json, the first address in the wallet returns the address
0x26cE5D1cD4CC673a1b0b980371C7c862B9503452 for ETH - If the hd_account_id
value is not set, the wallet will return the address
0x8c40a6E127c7a13e26ce95deA88354C3fb134580 for ETH

You can download and use this file as a starting point for your own coins file. It contains all of the coins that are currently supported by the Komodo DeFi API, and is maintained by the Komodo Platform team.
The structure for adding additional coins can vary, please refer to the listing guide or contact the KomodoPlatform team for assistance.
| Variable | Type | Description |
|---|---|---|
| MM2_CONF_PATH | string | A file path to load the MM2.json configuration file. Defaults to MM2.json in the same folder as the mm2 binary. |
| MM_COINS_PATH | string | A file path to load the coins configuration file. A comprehensive version for public use is maintained in the Komodo Platform coins github repository |
| MM_LOG | string | A file path to store the Komodo DeFi-API logs. |
| USERPASS | string | For convenience, this variable can store the value of your rpc_password to be referenced in any shell scripts |
