Is there a way to create paper wallet for EOS cold storage? And can these addresses also receive tokens.

I've integrated EOS key generation into my memory paper wallet generator project as seen below:

Live Demo: https://xcubicle.github.io/memorypaperwallet

Details: https://www.xcubicle.com/memory-paper-wallet-bitcoin-ethereum-monero-ardor-litecoin

Features:

  • Key generation is time and memory intensive to prevent brute force guessing
  • Printer friendly design
  • Fold to conceal the private keys when giving as a gift.
  • Background is user changeable for different occasions
  • Ability to generate multi-party keys using Shamir Secret Sharing Scheme.
  • Remember a user/pass combination to generate the same keys in case of loss when giving away as gifts.

Yes, you can generate a keypair using eosjs-ecc, create an account that uses that keypair for owner key, and keep your private key safe.

Example process:

  1. Install the library

    $ npm install eosjs-ecc
    
  2. Create a keypair

    $ node
    > const ecc = require('eosjs-ecc')
    > ecc.randomKey().then(privateKey => {
       console.log('Private Key:\t', privateKey) // wif
       console.log('Public Key:\t',  ecc.privateToPublic(privateKey)) // EOSkey...
      })
    > Private Key: 5KCyCHxCRwV7EH5VWUt2AFeVo2vRu2HgBGFsAwoF5CokwTa4mEa
    Public Key: EOS8E8FjakRz1a5Tw4YJQb6QMFC6ah1SWf3LEBpHCffH48G7mYWMj
    
  3. Import the private key in your wallet

    $ cleos wallet import 5KCyCHxCRwV7EH5VWUt2AFeVo2vRu2HgBGFsAwoF5CokwTa4mEa
    
  4. Create an account with that key

    $ cleos system newaccount <parent-account> <new-account> <public-key> --stake-net 10.0000 EOS --stake-cpu 10.0000 EOS --buy-ram-kbytes 20
    
  5. Write your private key somewhere safe offline

Note that this process can be made more secure using typical paper wallet practices such as using a newly installed operating system on an air-gapped machine, using multisig, creating a hierarchy of permissions, etc.
