Watch as $ZEC sucks up all onchain value
The problem Zcash Sucks solves
Zcash is sucking up all onchain value.
As the ultimate privacy-preserving cryptocurrency, $ZEC is the definitive way for humans to protect their capital from nation states and adversaries.
zcash.sucks was created to visualize all transparent, onchain money moving into $ZEC.
This dashboard surfaces hard numbers by tracking USD volume flowing into ZEC through NEAR Intents 1Click swaps from any chain (BTC, ETH, SOL, etc).
Challenges I ran into
The main issue was the NEAR Intents API rate limit of 1 request every 5 seconds.
I had more than 24,000 $ZEC transactions to process, and calculating all-time volume required 25 plus paginated calls.
My first pass hit the 429 wall fast and the API stayed rate limited for almost a full day.
I fixed it by rebuilding the entire fetching flow, no more fetching on page load, everything runs in the background. I added a caching layer that separates user traffic from API calls, spaced paginated calls with a 6 second delay, and switched to incremental updates that only fetch new transactions. That brought the load down from 25 plus calls per run to a single call every two minutes.
I added exponential backoff and a fallback dataset so the site still works when the API slows down.
