History Changes DeFi 📊
What if a decentralized exchange could reward users based on their previous activity?
Consider a wallet that has consistently traded through a protocol for the past 30 days.
Instead of offering the same fee structure to every wallet, a developer could design a liquidity pool that checks historical trading activity before applying a discount.
The challenge?
Smart contracts don't naturally have access to every historical calculation they might need.
Space and Time's Proof of SQL provides a way to verify supported queries against committed data.
Its Uniswap v4 hooks materials demonstrate customizable templates for this exact category of application.
One example is a loyalty discount template:
1️⃣ Check historical activity.
2️⃣ Calculate discount eligibility.
3️⃣ Generate a cryptographic proof.
4️⃣ Apply the result through the hook's logic.
For developers building within the
$UNI ecosystem, these templates show how historical data can support more personalized DeFi experiences.
The
$SXT network provides infrastructure for the associated data workloads.
These are available development templates, not a claim that every example is deployed in production.
Historical activity becomes much more useful when applications can verify the calculations behind it.
