# One-Click Trading (1CT)

> Reduce repeated wallet confirmations with one-click trading.

## Overview

One-click trading (1CT) removes the need to interact with a wallet when submitting transactions, reducing time to trade.

It does this through the use of two new mechanisms:

* 1CT wallet
* Trade delegation

## 1CT Wallet

Gains uses a derived externally owned account (EOA) wallet for submitting trading transactions.

It relies on the following sequence:

1. Trader provides a 4 digit PIN
   * *This pin should be remembered for future recovery*
2. Trader signs a prefixed message of the PIN using their wallet
   * *The wallet used to sign the message should be remembered for future recovery*
3. Gains website generates an Secp256k1 key pair using the signed message as a seed
4. Gains website encrypts and stores the key material on the local device

> Key material is deterministic meaning it can be replicated. Pin + personalSign gives strong security guarantees while allowing a trader to recover material if lost. A trader can also use this to prevent storing on device between trading sessions (clear and regenerate for each session).

Once a trader creates a 1CT wallet, they must grant it permissions to trade on their behalf by approving it as a delegate.

## Trade Delegation

Gains smart contracts support a delegation feature, allowing EOAs to submit transactions on behalf of other EOAs.

To delegate trading to another EOA, a trader must approve the address as a delegate through the trading contract.

A delegation wallet only needs gas funds for submitting transactions, as collateral and PnL are tied to the trader address.

<Accordion title="Supported delegate actions">
  * Open a trade
  * Open an order
  * Cancel an order
  * Update stop loss
  * Update take profit
  * Close a trade
</Accordion>

The 1CT wallet is a delegation wallet.

## Onboard

## Use

Once onboarded, a trader may enable the feature and use their normal trading workflows. At this point there is nothing different other than not having to confirm transactions in a wallet.

## Transactions

Because 1CT wallet is managed by the site, transaction management is taken in-house. This provides a place to track transactions and interact if they're stuck by speeding up or canceling.
