Our lightwallet implementation is built on top of eth-lightwallet (https://github.com/ConsenSys/eth-lightwallet). Eth-lightwallet is an HD wallet that can store your private keys encrypted in a browser. This allows you to run Ethereum dapps even if you’re not running a local Ethereum node. This is the same eth-lightwallet library used by Digix, Metamask, Jaxx and others. Still in beta, this eth-lightwallet is presently not recommended for the storage of large amounts of ETH.
The SingularDTV Lighwallet stores and transacts both ETH and SNGLS tokens. SNGLS are the token that power the SingularDTV ecosystem. Once SingularDTV’s Smart Contract System (SCS) is deployed, SNGLS can be bought directly from this lightwallet or through the Mist wallet using SingularDTV’s deployed contracts.
