Risk
The ways this loses money, stated plainly, worst first.
The risks
Bridges
HighEvery harvest crosses a bridge to Robinhood Chain. The vault never holds more than one epoch of fees on a source chain, but a paused or drained bridge costs that epoch.
Silence
MediumIf nobody trades ZEC, nobody pays. NAV never falls with price, but it can go flat for as long as every venue is quiet.
Contract risk
MediumThe vault and the registry are unaudited, and so is Pons v2, where the token launches. Ninety-one tests reduce the bug surface, not to zero.
Price risk
Structurally lowThe vault holds fee claims, never ZEC positions. ZEC dumping 30% is a busy day for the harvest, not a drawdown in ZEC.
Bridges
This is the sharpest one and it is structural. The vault's income is earned on four chains and settles on Robinhood Chain. Every harvest crosses a bridge, and a bridge can be paused, drained or repriced. The vault never keeps a balance on a source chain longer than an epoch, so the exposure at any moment is one day of fees, not the principal, but one day of fees across a bad week is real money.
The other half is the venue itself. A concentrated-liquidity position that goes out of range earns nothing until the provider moves it, and the vault does not control the position. The registry watches accrual and drops a pool whose stream has been silent for three epochs.
Silence
The vault is long activity. If ZEC goes quiet on every chain at once, harvests shrink toward zero and NAV goes flat. It does not fall, because there is no inventory to mark down, but flat is not free: you are holding an asset with an opportunity cost and no upside until people trade again.
Contracts
The ZecYield vault and registry are unaudited. Pons v2, where the token launches, is also unaudited at the time of writing. Ninety-one Foundry tests cover the gates, the split, the vesting, the sandwich, reclaim after term and a reentrant seller; they reduce the bug surface, not to zero.
Two more sharp edges before you size a position. The token and the vault share a ticker and nothing else, and sending one to the other's address is unrecoverable. And a seller contract that refuses its payout will revert the whole harvest batch; the mitigation is exclusion from the batch, which is a keeper action, not an automatic one.
