Otherwise we would need another bluetooth command to derive the key again. ## Methods ### getAddress #### Description Get address by address index. The XRP address generated is compatible to BIP44 with **account** and **change** set to 0, which means calling `getAddress` with `addressIndex = i` will get the address of folllowing path: ```none m/44'/144'/0'/0/{i} ``` In the design of current hardware, we only support path `m/44'/144'/0'/0/{i}` for speed optimization. This might change in the future and we will then open a more general interface to deal with custom path. ```javascript async getAddress( transport: Transport, appPrivateKey: string, appId: string, addressIndex: number ): Promise ``` #### Arguments | Arg | Description | Type | Required | |:-------------:|:--------------------------------------------:|:---------:|:--------:| | transport | Object to communicate with CoolWallet device | Transport | TRUE | | appPrivateKey | Private key for the connected application | string | TRUE | | appId | ID for the connected application | string | TRUE | | addressIndex | The from address index in BIP44 derivation | number | TRUE | ### signTransaction #### Description Sign Ripple Transaction. ```javascript async signTransaction(signTxData: signTxType):Promise ``` #### signTxType Arguments | Arg | Description | Type | Required | |:-------------:|:--------------------------------------------------------------------:|:---------:|:--------:| | transport | Object to communicate with CoolWallet device | Transport | TRUE | | appPrivateKey | Private key for the connected application | string | TRUE | | appId | ID for the connected application | string | TRUE | | payment | Essential information/property for XRP Transaction | Payment | TRUE | | addressIndex | The from address index in BIP44 derivation | number | TRUE | | confirmCB | Callback of confirmation data to the connected application | Function | FALSE | | authorizedCB | Callback of authorized transaction data to the connected application | Function | FALSE | --- _Source: https://npm.io/package/@coolwallet/xrp · Machine-readable twin of the npm.io package page.
