REQUEST INFORMATION

Assets

1. The following price feeds are crucial for enabling the advanced functionalities of our Paymaster. We are requesting oracles for:

USDC

WETH

Methodology

The selected methodologies that will define the feeds are:

Pricing methodology: Volume Weighted Average Price with Interquartile Range (VWAPIR) will be used to calculate the price for the assets. Learn more about it here

.5% deviation threshold for updates trigger will be applied for each asset

120 secs update frequency check will be applied

24-hour time-based update frequency will be applied for all assets

DELIVERY INFORMATION

Select if the feed should be delivered on-chain via oracle and if so, which network:

Delivery method: Arbitrum

Testnet required: Yes

Additional relevant information:

GasX is building a next-generation Paymaster under the ERC-4337 standard, designed to solve two key problems for dApps: the high cost of gas sponsorship and the lack of flexibility in sponsorship policies.

The integration with DIA’s oracles is fundamental to our two core features:

1. Capital-Efficient Paymaster: Funds deposited by dApps for sponsorship will be placed into low-risk protocols like Aave to generate yield. This yield will then subsidize a portion of the gas costs, making our service structurally cheaper. To safely manage this treasury, we require reliable, real-time price feeds for aTokens (e.g., aUSDC/USDC).

2. Programmatic Paymaster (Growth Engine): Our rules engine will allow dApps to create dynamic sponsorship policies to incentivize specific user behaviors (e.g., “sponsor the first transaction for a new user” or “sponsor swaps over $100”). To enable these value-based rules, we need accurate price oracles for major assets like WETH and USDC.

This integration with DIA is not just an enhancement but a critical requirement for launching a product that offers real, differentiated value in the Account Abstraction ecosystem.
