Integration notes
What matters before production
Polygon keeps EVM integration familiar
Polygon uses Ethereum-compatible addresses and transaction tooling while offering lower transfer costs for many users.
Network labels still matter
An Ethereum-style address can exist on several EVM chains. Checkout must clearly identify Polygon PoS before funds are sent.
One webhook contract covers every network
Your backend receives the same order, amount, status, network, and transaction fields used by the other BoltUtil chains.
