One thing I find interesting about @zerufinance is how it turns wallet activity into usable onchain trust.
Instead of treating every wallet like a complete unknown, Zeru provides trust oracles that can help applications understand activity and make better decisions around users.
One example is Zaps, where these trust signals can power activity markets.
But the bigger utility goes beyond markets.
Zeru also provides wallet screening APIs that can be used for AML checks, credit assessment, and access control.
And with zScore now live on etherscan, wallet reputation becomes something protocols can actually reference when evaluating onchain addresses.
