How We Deployed Smart Contracts to Polygon Mainnet

When we started Aurora Pathways, we made one decision that shaped everything: every contract we write ships to mainnet with verified source code and a passing test suite. No "testnet-only" demos. No unaudited code. Real contracts, real blocks, real Polygonscan verification.

Here's exactly how we do it — the pipeline, the tools, and the discipline that's produced 863 passing tests across 4 protocols with zero failures.

The Pipeline

We use Foundry for the entire lifecycle. No Hardhat, no Truffle, no JavaScript tooling for contract work. Everything in Solidity, tested in Solidity, deployed from the command line.

A typical deployment flow looks like this:

# 1. Write the contract + tests (Solidity, same language)
# 2. Run the full test suite
forge test --via-ir -vvv

# 3. Fuzz test for edge cases
forge test --fuzz-runs 10000

# 4. Deploy to Polygon mainnet
forge create --rpc-url $POLYGON_RPC \
  --private-key $DEPLOYER_KEY \
  --verify \
  --verifier polygonscan \
  src/TaskEscrow.sol:TaskEscrow

# 5. Verify on Polygonscan (automatic with --verify)
# 6. Tag the release in git

Every step is scripted. No manual bytecode verification. No copy-pasting ABI into a web form. The entire deployment is reproducible from a single command.

Why 863 Tests Matter

A test suite isn't about the number — it's about coverage of real failure modes. Our tests fall into three categories:

Unit tests verify individual functions work correctly. Integration tests verify contracts interact correctly with each other (e.g., escrow → payment release → fee distribution). Fuzz tests throw randomized inputs at functions to find edge cases no human would think to test.

We caught a reentrancy vulnerability in our escrow contract during fuzz testing that would have passed a manual audit. The fuzzer found it in 3 seconds. That's the kind of thing that separates production code from demo code.

Polygonscan Verification: Why It's Non-Negotiable

Verified contracts on Polygonscan mean anyone can read your source code, confirm it matches the deployed bytecode, and audit the logic themselves. It's the blockchain equivalent of open-source — and it's the single strongest trust signal you can give a client.

Every Aurora Pathways protocol is verified. You can read the source for TaskEscrow, PledglySubscription, ForekastMarket, and RideP2P right now.

What This Means for Clients

When you hire us, you're not paying for speculation. You're paying for a pipeline that's already produced 4 mainnet deployments with verified contracts and a clean test suite. The code that ships for your project goes through the same pipeline. Same rigor. Same results.
