How did you integrate our partners, if any?

To expand the accessibility of our service, we’ve integrated Across Protocol as a bridging solution. This allows users holding tokens on Ethereum Mainnet to interact with our pools on Base seamlessly.

Example:

1. A user wants to sell DAI for USDC, but their DAI is on Ethereum Mainnet.
2. Across automatically bridges the DAI to Base.
3. The swap executes in our pool using the Hook logic.
4. The user receives USDC directly on Base Mainnet.

Problem / Background: What inspired the idea? What problems are you solving?

Traditional on-ramping services must hold reserves of many different tokens to meet user demand. This creates complex, costly liquidity management and exposure risks.

Ramphook solves this by relying solely on USDC for liquidity, while still enabling access to any token listed on Uniswap v4 as long as a TokenX/USDC pool exists and is connected to our custom Hook.

Moreover, our model creates win-win incentives for all participants: Onramper users, LPs, and Swapper users.
