"this file had to be altered because your coin is not listed on poloniex.  I entered in the static value of BTC/KMD. I got this value from the komodo page at https://komodoplatform.com/faq/

edit the static value for "self.poloniexRate" whenever the value of your coin changes, or point it at a self-updating resource."

this other file had some type exceptions that needed changes. the buffer length for your coin is 21 instead of 22, and your coin does not have networktype, or addresstype  stored in the buffer, so there isn't any reason to check for a value that will always be undefined.

 * Instantiate an address from an address String or Buffer, a public key or script hash Buffer,
 * or an instance of {@link PublicKey} or {@link Script}.
 *
 * This is an immutable class, and if the first parameter provided to this constructor is an
 * `Address` instance, the same argument will be returned.
 *
 * An address has two key properties: `network` and `type`. The type is either
 * `Address.PayToPublicKeyHash` (value is the `'pubkeyhash'` string)
 * or `Address.PayToScriptHash` (the string `'scripthash'`). The network is an instance of {@link Network}.
 * You can quickly check whether an address is of a given kind by using the methods
 * `isPayToPublicKeyHash` and `isPayToScriptHash`
 *
 * @example
 * ```javascript
 * // validate that an input field is valid
 * var error = Address.getValidationError(input, 'testnet');
 * if (!error) {
 *   var address = Address(input, 'testnet');
 * } else {
 *   // invalid network or checksum (typo?)
 *   var message = error.messsage;
 * }
 *
 * // get an address from a public key
 * var address = Address(publicKey, 'testnet').toString();
 * ```
 *
 * @param {*} data - The encoded data in various formats
 * @param {Network|String|number=} network - The network: 'livenet' or 'testnet'
 * @param {string=} type - The type of address: 'script' or 'pubkey'
