 ## Example of RNode connection to Metamask (with hardware wallet)
 
 RNode has support for Ethereum type of signatures so Metamask can be used for signing deploys e.g. making transfers of REVs. In Web example, button to add selected Metamask account should be visible next to REV import textbox.
 
 Helper functions are in [eth-wrapper.js](src/eth/eth-wrapper.js) which contains the code for communication with Metamask, getting selected ETH address and sending deploys for signing.
 In [eth-sign.js](src/eth/eth-sign.js) are functions to verify deploy signature and to extract public key.  
-This is all that is needed for communication with Metamask and also for connected hardware wallets (Ledger). How to use these functions and send deploys to RNode is in [rnode-web.js](src/rnode-web.js).
