Three parties, one protocol

Polyark connects traders, investors, and Polymarket through smart contracts that enforce trust programmatically.

01

Manager creates a vault

Traders deploy an ERC-4626 vault through the Polyark factory, setting their performance fee, kill switch threshold, and timelock parameters.

02

Investors deposit capital

LPs deposit USDC and receive vault shares. The smart contract enforces that the manager can only interact with whitelisted Polymarket contracts — funds cannot be misappropriated.

03

Manager trades, NAV accrues

The manager executes trades on Polymarket. As positions resolve, NAV updates on-chain. Performance fees accrue automatically above the high-watermark.

04

Investors withdraw at NAV

Withdrawals are processed at current NAV, with performance fees deducted at the per-redemption level. Large withdrawals are timelocked to protect remaining investors.

Built for real capital

Every safeguard is enforced by the smart contract. Not by policy, not by the manager's goodwill — by code.

Exchange whitelist

Managers can only call whitelisted Polymarket V2 contracts. Arbitrary transfers or contract calls revert at the EVM level. Funds are structurally inaccessible to the manager.

Kill switch

If drawdown exceeds the configured threshold (e.g. −15%), trading is automatically paused. Only the admin role can lift it, preventing the manager from continuing to lose investor capital.

Withdrawal timelock

Large withdrawals (above a configurable % of AUM) are queued with a time delay. This prevents a rush of exits from forcing fire-sale liquidations of open positions.

High-watermark fees

Performance fees only accrue on profits above the all-time high NAV. Accrued fees are excluded from totalAssets() so remaining investors don't subsidise unpaid fees through NAV inflation.

ERC-4626 standard

Vault shares are composable, transferable ERC-20 tokens. NAV is always calculable on-chain. Compatible with any DeFi tooling that supports the standard.

On-chain NAV oracle

An EIP-712 signed price feed prices open CTF positions for accurate NAV calculation. Price bundles are publicly verifiable and subject to staleness checks.

Two sides of one market

Polyark exists at the intersection of traders who need capital and investors who need expertise.

For traders

You have edge. Scale it.
