The fee-claim layer
for Zcash.

zYLD holds the fee stream of every pool ZEC trades in, never the coin. You are long how much ZEC changes hands, not what it changes hands at. Settled on Robinhood Chain.

Explore the mechanics

The vault owns the claim, not the coin

Every pool ZEC trades in charges an LP fee on every swap. A liquidity provider sells the vault that fee stream for a term and is paid in ETH up front. The position never moves, the ZEC never moves, and the vault carries none of the price.

Wherever ZEC trades, the fee comes home

Zcash has no DEX of its own, so its volume lives on Solana, NEAR, Base and BNB Chain. The vault holds rights on all of them and settles every harvest in one place: Robinhood Chain, in ETH.

Harvest every epoch, along λ₁

Once a day the keeper collects every eligible stream, swaps it to ETH, bridges it to Robinhood Chain and books it to NAV with a linear vest. Harvested ETH buys more streams, weighted by the first eigenvector.

One ticker, on Pons v2

zYLD is one ERC-4626 share over the whole basket, and the zYLD token launches on Pons v2 on Robinhood Chain. Deposit ETH at NAV, redeem any time, trade the token on the pool.

The spectrum.

Each stream is one pool's fee flow over the last 168 hours. The tilted line is λ₁, the first eigenvector of the fee matrix. What projects onto it feeds the core; what doesn't, scatters.

model

Dump ZEC. The fee vault doesn't care.

Holding ZEC is long price. ZecYield is long the number of times ZEC changes hands, and a dump is the most-traded day of the year. The vault is paid in fees, not in ZEC, so its NAV never sees the price. Pick a severity and press the button.

Why “eigen”.

ZEC pool fees are correlated. When ZEC is moving, every venue on every chain earns more; when it is quiet, every venue earns less. Stack the hourly fees of every gated pool into a matrix and take its first principal component. That is the market yield, and it is the only thing zYLD pays for.

λ₄ = 0.979.7%

λ₁ is the market-yield factor. When ZEC is being traded, every venue's fees rise together, on Solana, NEAR, Base and BNB Chain alike; that shared movement is what zYLD holds. Everything after λ₁ is single-venue noise the vault does not pay for.

The spectrum is public. So is the API.

Pools, λ, loadings, weights, NAV and the epoch clock are served from this site's own backend on Vercel, with no key. The Solidity is in the repo with its tests.
