The problem ShillEarn solves

Most DEXs and aggregators focus purely on the trader experience but none reward the people driving volume: the shillers.

ShillEarn flips the script: it lets anyone generate a referral link for any token, earn 0.5% on every trade they drive, and even get 0.1% from their referred shillers’ activity.
We turn engagement into measurable, onchain revenue.

What it solves:

Gives shillers, memecoin promoters, and KOLs a way to earn directly from their impact

Tracks and rewards viral token sharing automatically

Helps DEXs capture more volume via incentivized distribution

Makes swaps more rewarding and transparent for everyone

It’s the missing monetization layer for Farcaster-native and Twitter-native token shilling and it’s live on Base.

Challenges I ran into

The biggest challenge we faced was designing a referral system that was both onchain, gas-efficient, and resistant to abuse.

We knew from the start that rewarding users with a percentage of each swap would open the door to farming and sybil attacks.
So we had to be extremely careful with:

Tracking referrals reliably across both EVM and Farcaster

Avoiding double-counting or circular referrals

Preventing zero-fee farming attempts from bots

We also wanted to reward people even if they didn't initiate the swap themselves, as long as they helped amplify token discovery. This required designing a fee collection and distribution flow that was fully automated but transparent.

We overcame this by splitting the system in two smart contracts:

One for handling swaps + fee extraction (gas-optimized, upgradeable)

One for managing fee claims, point attribution, and ref relationships

We also added an offchain proof-of-activity system for bonus features (streaks, XP, badge tracking) to stay flexible and fast.

It was a lot of iteration, especially while keeping everything Base-native and L2 cheap, but we’re proud of the result:
A system that scales from degen memes to legit campaigns without breaking.
