The dip · cold capital
This is where we deploy.
Cylus is an onchain fund that writes checks across the entire market cycle — and leans hardest into the part everyone else is afraid of. When the timeline is quiet and the charts are red, conviction is cheapest. So that's when we move.
The climb · conviction compounds
Capital, deployed across the curve.
We don't pick a single entry and pray. Cylus deploys through the whole ascent — into the teams turning a quiet thesis into something the market can't ignore. The round is open; the focus is below.
The peak · maximum noise
We back the builders, not the noise.
At the top everyone's a genius and every chart's a rocket. The memes scream; the founders keep shipping. We fund the second kind. Always have.
The turn · the crowd exits
The crowd takes profit. We take notes.
Tops are built from certainty. While the exit liquidity cheers, we're watching which products keep their users when the price stops being the reason.
The winter · the real ones stay
Build through the winter.
Winter is a filter. The tourists leave and the builders stay, heads down, shipping to nobody. If that's you, we're already here — and the round is open.
Our Focus
L2 / L3
Execution, rollups, app-chains, and the rails beneath them.
DeFi
Onchain markets and primitives that clear without permission.
Infrastructure
Indexers, oracles, tooling — the unsexy middle builders depend on.

Treasury
Not a pitch deck — the fund's actual wallet, read live from the Solana chain. Every position and its weight, updated in real time. Nothing to take on trust.
Reading the chain…
Who's behind Cylus
We don't pad this page with a fake team. Cylus is run by a solo builder who ships onchain products, backed by a small network of operators. When there are more real names to put here, they'll go here.
Cylus
Solo builder · ships onchain products
Building and backing Solana-native products across the cycle. Pseudonymous for now — real names come on the call, not on a landing page.
Portfolio
Open round
No portfolio to inflate yet — the first checks are being written. Yours could be one of them.
