Audit, Verify & Interact with On-Chain Contracts

Smart contract verification is the process of publishing a contract's source code so that anyone can audit its logic. Once a Polygon contract is verified, PolygonScanner displays the human-readable ABI, the Solidity source, and interactive Read/Write panels — no local development environment required.

How Verification Works

When a developer deploys a contract, only bytecode is stored on-chain. Verification compiles the source code with matching compiler settings and confirms the resulting bytecode is identical to what is deployed. This process proves the published source accurately represents the running contract.

Reading a Verified Contract

The Read Contract tab exposes all view and pure functions. Enter any required parameters and click Query to retrieve the current value stored in the contract — useful for checking token allowances, governance states, or oracle prices without spending gas.

Writing to a Verified Contract

The Write Contract tab lets you call state-changing functions directly from your browser wallet. Connect MetaMask or any WalletConnect-compatible wallet, select the function, fill in the parameters, and submit the transaction.
