Identity Vault

Hash.js

We created a secure interface to manage identity on different sites and sign transactions.

let data = {
    recipientlist:'[{"tinybars": "444", "to":"0.0.1107"}]',
    memo:"My First Hedera Transaction"
}

window.hash.triggerCryptoTransfer(data, (err, res) => {
    console.log("Callback::Error:", err)
    console.log("Callback::Response:", res)
});
