Mezz Lab

A read-only lab for Mezzanine vault depositors.

What Mezz Lab is

What it shows. Mezzanine vault data in more depth than the app: projected APYs, the weekly payout cycle, what a strategy loss would mean for each tranche, and an address lookup for any wallet's positions.

Why it exists. It's where new ways of showing vault data get tried out. The ones depositors find useful may be built into the Mezzanine app.

What it isn't. A place to move money. It never asks you to connect a wallet or sign anything, and you can't deposit or withdraw here. Use app.mezz.finance for that.

Projected APY

How you're paid. Each epoch's yield is paid out over the following week. The Senior and Junior amounts are fixed at the report and shared by whoever holds each tranche while it pays out, so new deposits lower that tranche's rate.

What the app shows. A trailing 7-day APY: what the last week paid out, so it lags behind.

What we show. The latest reported payout, spread over today's balances, so you see its rate before the app catches up. The amount is fixed at the report, but the rate moves as people join or leave each tranche. It's not a guarantee of future payouts.

Unstaked mzUSD earns nothing itself, but it is deployed in the strategy and all of its yield goes to Senior and Junior. That multiplies the rate for everything staked. Every rate is APY, because yield compounds in the vault.

Epoch Timeline

Where we are in the weekly cycle. Yield earned this week is reported near the end of it, held for a 24 hour veto, then paid out evenly over the next week. That lag is why the app's APY trails what the strategy is earning now.

Tranche Yield Curve

How the split changes each tranche's APY. Junior earns a risk premium on top of the base reward for taking losses first. When Junior is a small part of tranche capital that premium is shared by fewer people, so Junior's APR is high, and it falls as more capital moves into Junior. The marker shows today's split.

Base reward and risk premium at every 1% of Senior share. Gold tags mark the premium floor, the target and the premium cap; the blue row is the current split.

Tranche Split

Who takes a loss, and how much. All mzUSD is deployed, staked or not, so a strategy loss comes out of the whole pot: Junior first, then Senior, then unstaked mzUSD. Junior is a small buffer for a much larger pot, so a small strategy loss is a large loss for Junior. Drag the slider to see each tranche's share.

Look up any wallet address to see its Hastra Optimizer positions, what they have earned, and how much a strategy loss would affect them. Read-only: nothing to connect or sign. To fetch the data, the address is sent to the Mezzanine app's API and a public Ethereum node, which can see the lookup and your connection. Mezz Lab keeps no record of it.

Epoch Timing

When to unstake, and when to deposit. An unstake unlocks at the end of a set epoch (the next one for Senior, the one after for Junior), so asking just before an epoch ends is quickest. Deposits start earning straight away.

Earnings

What this address has earned. Earnings come from each tranche's share price, which rises as yield is paid out. They're shown in USDC: 1 mzUSD is backed by 1 wYLDS, which is pegged to USDC. Unstaked mzUSD earns nothing itself.

Allocation

Where this address's mzUSD sits. Senior earns the base reward, Junior earns more for taking losses first, and unstaked mzUSD earns nothing but is the last to take a loss.

Positions

What each position holds and earns. Its value, shares, what it has earned, its projected APY, and when an unstake requested now would unlock.
