About Loopring Wallet

Loopring Wallet, founded by Daniel Wang, Jay Zhou, and Johnston Chen in 2017, is a secure Ethereum wallet with advanced trading functionality and innovative Earn products. Based in Shanghai, China, Loopring has raised $87M in funding and employs a small team of 1-10 people. The wallet is integrated with the Loopring Protocol, a ZKRollup implementation designed to scale Ethereum for trading, and offers features such as ultimate security, low transaction fees, and high throughput. Developers can also use Loopring's zkRollup technology to build scalable payment apps, non-custodial exchanges, and NFT marketplaces.

General usage

Here's a brief summary of Loopring Wallet’s APIs:

1. Trade or Swap APIs: These APIs enable programmatic trading, allowing users to trade digital assets efficiently. They are designed to support the decentralized exchange (DEX) functionalities Loopring offers, leveraging their zkRollup technology for high-speed and low-cost transactions.
2. Loopring Smart Wallet APIs: These APIs are designed for integration with the Loopring Smart Wallet. They offer functionalities like setting up guardians for social recovery, cloud backup, and enabling Two-Factor Authentication (2FA) to enhance wallet security and user control.
3. Loopring Protocol APIs: These APIs are part of the core Loopring protocol, allowing users and developers to interact with the protocol's features, including token transfers, and managing decentralized exchanges built on Loopring.

Rate Limits

Here’s the rate limit:

• The API returns two minimum amounts:
• One amount is based on the user's fee rate.
• The other is based on the maximum fee bips, which is 0.6%.

Authentication

This is how you authenticate your Loopring Wallet API:

1. Register a wallet address in the Loopring DEX to get an account ID. You can do this in two ways:
2. via API: Make a deposit to your address by calling the Loopring exchange address. Once the Loopring exchange receives your deposit (8 confirmations), it will generate an account ID for your address.
3. via Website App: Use an account in Loopring Layer 2 to transfer some tokens to your address. After the transfer is successful, this will generate an account ID for the payee address.
4. Retrieve account information using the getAccount call with the newly acquired account ID.
5. Retrieve fees from the exchange using the getActiveFeeInfo call to know the fees required to update your account.
6. Update your account using the updateAccount call.
7. Retrieve your account API key using the getUserApiKey call, which requires an eddsa signature.

Make sure to have the Loopring SDK installed for these operations.

Errors

Here is the three most common API errors for Loopring Wallet:

• Error Code 100000 - Unknown error: This error indicates an unspecified problem has occurred. It's a generic error message when the exact nature of the error is not known.
