Key manager and transaction signer for the IOV, Ethereum and Lisk blockchains
Neuma is an extension for accessing IOV, Ethereum, and Lisk blockchains.
Neuma lets the user create and manage their own identities (via private keys, local client wallet), so when a Dapp wants to perform a transaction and write to a blockchain, the user gets a secure interface to review the transaction before approving or rejecting it.
Neuma is open-source. You can always "view the source" of Neuma the way you do any Chrome extension, or view the source code at https://github.com/iov-one.
Neuma is built by IOV SAS, 55 rue de La Boetie, 75008, Paris, France. https://iov.one/
