FatMbappe is going institutional 🏆

My $FAV8 World Cup Vault is live on @ZeitFinance.

We’re buying equal YES shares across the top 8 World Cup favorites. Current basket: ~81¢. Payout if one of them wins: $1.

Target gross upside: ~23.5% before fees.

@ZEITFinance This means that my vault APY is most likely even higher than displayed

@allquantor @ZEITFinance That's why I picked @ZEITFinance to run my vault. Best tech wins in the end

[Ivan @allquantor]

TLDR deep dive into @ZEITFinance under the hood, came out pretty elegant imo:

A minimal onchain share vault (boring-vault pattern: Vault + Teller + Accountant + FeeManager) wrapped around an offchain solver that turns Polymarket trading into a clean ERC-20 you can deposit into.

One atomic roll

Every epoch, ALL deposits + withdrawals settle in a single rollEpoch tx. Shares get bulk-minted once, then each user claims their cut with an O(\log n) Merkle proof instead of N onchain writes.

Trustless data availability

The full claim set + every Merkle proof is archived to Arweave; only the roots + the Arweave URI go onchain. Result: any roll is independently replayable, and you can self-serve your claim even if our servers are down.

Real mark-to-market

NAV doesn't just trust mid prices - it simulates selling each position into the live CLOB order book (slippage & fees aware) to get a realizable share price.

Omnichain shares, no bridge pool.

Vault shares ARE a native LayerZero OFT - lock on Polygon, mint on the destination chain. Sign
one EIP-712 intent and a relayer does claim-and-bridge for you, with the claim + bridge params cryptographically bound to that one signature

Shout out to @dvinubius @micovi7 to get this designed and built (before Mythos)

@ZEITFinance This is actually an extremely strict metric, most likely you will be able to cash out for more that the tokens value

[FatMbappe @TheFatMbappe]

@ZEITFinance My $FAV8 vault is basically only comprised of the most liquid markets (football world cup winners) on the platform so you're always gonna get extra NAV compared to other categories

[ZEIT @ZEITFinance]

How does ZEIT Finance value vaults to issue tokens? 🤔

While market price is whatever someone is willing to pay, the fundamental value is its redemption value: a pro-rata share of the Vault’s Net Asset Value (NAV).

Here’s how we calculate it fairly: 👇

@qwee_sneaker @PolymarketSport @PolymarketCS2 We ? Are you a team ?

[FatMbappe @TheFatMbappe]

@Autonomous_Chad Bullshit, they tryna keep me down

[FatMbappe @TheFatMbappe]

I'm being locked out of combos already !

"Combo unavailable. Something went wrong, please try again"

They know the top 8 is unbeatable

No one want to bet against me.

Too bad, i'll just continue running up my $FAV8 vault until they lift the fatwah against me

Skip the grind, just invest and forget

My vault already sitting on a clean +30% APY, two days in.

This will only increase as low tier teams get stomped.

They are objectively worth nothing but delusional fans will pump them, your job is to take their money.

If you're too lazy even for that, i'm doing it for you

In the meantime you can invest in my @ZEITFinance vault (top 8 rebalancing ETF $FAV8) and print off the back of delusional 4th tier team supporters
