Questions & answers

ZEIT Prime is the curated lane: indexes and event ETFs built by ZEIT on proven narratives and algorithms, sized against deep liquidity. The addressable figure on every Prime fund states that size.

Community is the open lane: long-running theses proposed by the community, shaped into investable vaults with ZEIT's AI, and run by their managers or their algorithms. Creation will be fully permissionless; today it is whitelisted while we harden the rails. Both lanes share the same accounting and the same non-custodial security.

An ERC-20 token, minted to your wallet at deposit. It represents your share of the vault.

Example: deposit $1,000 when the unit price is $1.00 and you hold 1,000 shares. If the vault's unit price marks to $1.10, your position is worth $1,100.

Two exits, your choice: sell the token like any ERC-20, or redeem it with the vault at the published unit price.

Non-custodial by construction: vault shares live in your wallet, not with us. Accounts work through Privy or any normal wallet you already use.

Every deployment is audited before it ships. Reviews combine LLM-assisted analysis with in-house security engineers.

At the core, a fork of the BoringVault architecture: a deliberately minimal vault contract with separated roles. The vault holds assets, a manager executes strategy within strict limits, an accountant publishes the unit price, and a teller handles deposits and redemptions.

On that base we built the prediction-market layer: cross-chain deposits (7 chains, Polygon hub), marking to realizable bids rather than mid or last trade, daily published unit prices, and performance fees only above a high-water mark.

Every fund keeps a cash buffer to honor short-term redemptions. That buffer is not idle: it can sit in low-risk instruments that generate passive yield for the fund while it waits.

Today the buffer earns around 3.7% through the Sky Savings Rate. That gives the ETF and its creator a market base yield before the strategy itself does anything.

Trading fees are paid to Polymarket, our current settlement provider (not an exclusive one going forward). Unlike normal retail execution, we run professional execution tooling and optimize for maker rebates: where possible the fund makes the market instead of taking it.

Making the market means lower fees, and the maker rebates flow back into the ETF. Those rebates subsidize trading costs, so the token tracks its underlying value at a lower cost to holders.

Yes. Every vault and ETF share is a standard ERC-20, compatible with Morpho, Aave, Uniswap, and any venue that accepts ERC-20 collateral.

The token represents the real value of the fund, with redemption at the published unit price, subject to the vault's underlying value. That makes it usable for borrowing and lending like any other productive asset.

Not yet. If you are a market maker and want in-kind creation or redemption, reach out.

Being reworked. Until the full documentation lands, this page is the source of truth. If anything here is unclear, tell us; we treat that as a bug.
