1-Click Transactions

1-click transactions

Tonomy ID allows users to sign and execute blockchain transactions directly from your app without needing to open Tonomy ID.

These transactions have lower security guarantees than wallet-signed transactions and are good for low-value actions such as creation proposals, updating settings or game actions.

1. Modify your Smart Contract

Smart contract @ Registered App account

If you have deployed the smart contract to the same account as your Registered App, then you can get the permission name with get_self().

token.cpp

token::transfer(const name &from,
                        const name &to,
                        const asset &quantity,
                        const string &memo)
{
    require_auth({from, get_self()});
    // Rest of your code below...
}

Smart contract @ different account

2. Sign the Transaction in Your App

const trx = await user.signTransaction('eosio.token', 'transfer', {
    from: "me",
    to: "you",
    quantity: '1 SYS',
    memo: 'test memo',
});

This will directly sign the transaction and send it to the blockchain in the user's browser, without them needing to open Tonomy ID. You may want to show a confirmation before, or after (such as with a Toast UI component).

If the contract is deployed to the Registered App, then the transaction does not communicate with Tonomy ID. Otherwise, it will need to send a message to Tonomy ID the first time it does this transaction to the contract.

This will prompt the user to sign the transaction in their Tonomy ID mobile app.
