Escrow (Polygon)

Escrow is a prediction market protocol deployed on Polygon-compatible EVM chains.

Recommended stack

• Foundry (Solidity + forge test)
• OpenZeppelin Contracts (SafeERC20/ReentrancyGuard)
• OpenZeppelin proxy contracts (proxy/impl pattern via TransparentUpgradeableProxy)

Quick start

1. Install Foundry: https://book.getfoundry.sh/getting-started/installation
2. From repo root:
   • cd polygon
   • git submodule update --init --recursive
   • forge build
   • forge test

Invariant tests

• forge test --match-path "test/invariants/*"

API notes

• trade(marketId, directionYes, amountIn, minSharesOut) includes slippage protection.
• resolve(marketId, updateData) uses an oracle adapter (config.oracle) and is payable to forward update fees (for Chainlink adapter this is 0).

Deployment

• See docs/AMOY_DEPLOYMENT.md for testnet
