How Holdstation Leverages zkSync's Paymaster for Gasless Leverage Trading

This guide provides a technical overview of how to trade on Holdstation, focusing on the core technologies from its Holdstation zkSync integration that enable its CEX-like experience: Holdstation Account Abstraction and the Holdstation Paymaster.

Step 1: Smart Wallet Creation (Account Abstraction)

When you onboard to Holdstation Official with a social login, you are not creating a standard wallet. The protocol utilizes ERC-4337 to deploy a unique Holdstation Smart Wallet for you. Your social account credentials act as a signer for this smart contract, abstracting away the need for a seed phrase.

Step 2: The Gas Sponsorship Model (Paymaster)

Holdstation achieves Holdstation gasless trading by using zkSync's native Paymaster feature.

How it Works: When you initiate a trade, your Smart Wallet signs a user operation. This operation is structured to call a Paymaster contract. This contract is funded by the Holdstation protocol and is configured to pay the gas fees for user transactions, provided they meet certain criteria. The user never sees a gas prompt.

Step 3: Executing a High-Leverage Trade

Select a market for Holdstation leverage trading (up to 500x).

Define your position and sign the transaction with your social login/passkey.

The Paymaster sponsors the transaction, and it is executed on-chain.

Your activity is tracked, and your wallet accrues rewards in the form of uGOLD token rewards. For a full architectural overview, see the Full Official Documentation.
