Same tooling, different trade-offs
Polygon PoS is EVM-compatible, so contracts written in Solidity with Foundry or Hardhat deploy to both networks with little change. The decision is less about code and more about security model, fees, user base and the protocols you need to integrate with.
When Ethereum mainnet fits
- High-value assets where the strongest security and decentralisation matter
- Integration with DeFi protocols and liquidity that live on mainnet
- Institutional users who expect mainnet settlement
- Low transaction frequency, where higher fees per transaction are acceptable
When Polygon fits
- Consumer products with many low-value transactions
- Gaming, loyalty and collectibles where fees must be negligible
- Projects that want EVM tooling with lower cost
- Markets where Polygon ecosystem partners are already in use
Don't forget the Layer 2s
Ethereum rollups such as Arbitrum, Optimism and Base also offer low fees with security anchored to Ethereum. For many new projects the realistic shortlist is Ethereum mainnet, one or two rollups and Polygon — compared on fees, ecosystem, bridging and the wallets your users already have.
Deciding
Write down the value at risk, expected transaction volume, required integrations and your users' wallets, then compare two or three networks against them. Deploying to several networks is possible, but each adds operational overhead, so start with one unless there is a clear reason.
