// how_it_works

Three parties.
One protocol.

Polyark connects traders, investors, and Polymarket through smart contracts that enforce the trust model programmatically — no intermediaries needed.

01 / Manager

Deploy a vault

Traders deploy an ERC-4626 vault through the Polyark factory. Set performance fee, kill switch threshold, and withdrawal timelock in one transaction.

02 / Investor

Deposit capital

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

03 / Manager

Trade, NAV accrues

The manager executes trades on Polymarket V2. As positions resolve, NAV updates on-chain via the EIP-712 oracle. Fees accrue automatically above the high-watermark.

04 / Investor

Withdraw at NAV

Redemptions are processed at current per-share NAV. Performance fees deduct at the per-redemption level. Large withdrawals trigger a timelock to protect remaining investors.

// protocol_design

Built for real capital

Every safeguard is enforced at the EVM level. Not by policy, not by the manager's goodwill — by code that cannot be overridden.

Exchange whitelist

Managers can only call whitelisted Polymarket V2 contracts. Arbitrary transfers revert at the EVM level. The vault's collateral is structurally inaccessible to the manager.

Kill switch

If drawdown exceeds the configured threshold, trading is automatically paused. Only the admin role can lift it — the manager cannot trade through a losing streak.

Withdrawal timelock

Large withdrawals above a configurable AUM threshold are queued with a time delay, preventing rush exits from forcing fire-sale liquidations of open positions.

High-watermark fees

Performance fees only accrue on profit above the all-time high NAV per share. Accrued but unpaid fees are excluded from totalAssets() — remaining investors never subsidise them.

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 marks open CTF positions to market for accurate NAV. Runs every 5 seconds and submits on-chain only when prices move meaningfully.

// participants

Two sides.
One market.

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

For traders

You have edge. Scale it.

Running $50k when you could run $5M. Polyark gives you infrastructure to manage outside capital and earn performance fees on your existing strategy — without giving anyone your private key.

  • Deploy a vault in minutes, set your own terms
  • Earn 15–30% performance fees on profits above HWM
  • Verifiable track record, on-chain from day one
  • Smart contracts enforce your terms — no disputes
For investors

Access returns you couldn't capture alone.

Prediction markets are alpha-rich but time-intensive. Allocate to proven traders and capture returns you couldn't generate yourself — with protections you can verify on-chain.

  • Deposit USDC, receive tradeable ERC-20 vault shares
  • Manager execution whitelisted to Polymarket only
  • Automatic kill switch on large drawdowns
  • Withdraw at current NAV, or sell shares on OTC market
