Convallax is live on Polygon Amoy testnet (chain ID 80002). Everything — option tokens, collateral, and settlement — uses testnet USDC with no real money at risk.

​
Prerequisites

  • A wallet that supports Polygon Amoy (MetaMask, Rabby, or any EVM wallet)
  • Amoy testnet POL for gas fees

​
Set Up Your Wallet

1

Add Polygon Amoy to your wallet

Most wallets auto-detect the network. If not, add it manually using the values above.
2

Get testnet POL for gas

Visit the Polygon Amoy Faucet to receive free testnet POL for transaction fees.
3

Get testnet USDC

Convallax includes a built-in faucet. Visit the app and click Get Test USDC to receive testnet tokens, or call the API directly:
The faucet drips 1,000 USDC per request with a 24-hour cooldown per wallet.

​
Contract Addresses

All contracts are deployed on Polygon Amoy (chain ID 80002): View any contract on Amoy Polygonscan.
The testnet USDC above is a custom MockUSDC token deployed by Convallax — not Circle’s USDC. The entire deployment is collateralized in this token, so it is the only USDC that works here. Get it from the Convallax faucet (the Get Test USDC button in the app, or POST /faucet) — minting is owner-gated, so the faucet is the only way to obtain it. Import this address into MetaMask to see your balance (6 decimals).

​
Your First Trade

1

Visit the trading interface

Go to convallax.com/predict and connect your wallet.
2

Select an option

Choose a prediction market, pick your strike price and expiry, and select Call or Put.
3

Set your size

Enter the number of options you want to trade.
4

Submit your RFQ

Sign the EIP-712 request with your wallet. Market makers will compete to quote you a price.
5

Accept and fill

Review the best quote and approve. Your wallet will prompt you to call fill() on-chain, which atomically pays the premium, locks any required collateral, and mints your option tokens in one transaction.

​
Available Markets

Convallax supports option grids registered by the protocol team. The current testnet deployment includes the 2026 FIFA World Cup winner markets: To discover the available markets and series programmatically, use the List Markets and List Series endpoints.
New markets are registered by the protocol team. Series must exist on-chain before options can be traded. If you’d like a specific Polymarket market supported, reach out at support@convallax.com.

​
Approvals

Settlement is atomic mint-on-fill — option tokens are minted when a trade executes, so there are no ERC-1155 approvals. You only ever approve USDC:
  • Buying options (long): Approve USDC spending by ConvallaxRFQSettlement (premium).
  • Selling options (short): Approve USDC spending by ConvallaxCore (collateral, posted at fill).
The frontend handles approval prompts automatically using the takerApproval returned by the commit response.

​
Verify Your Positions

After a trade, you can verify your option token balances on-chain:
