Keep Polygon Service Payments Funded With POL

To keep Polygon service payments running, hold POL in the wallet that submits each transaction. Since September 2024, POL has been the native gas token on Polygon PoS, so a balance of the service’s payment token alone may not cover the network fee.

• Identify the chain and wallet that send the payment.
• Keep POL in that wallet for transaction fees.
• Check the balance before scheduled or automated payments.

Why does a Polygon payment need POL?

On Polygon PoS, the network charges gas in POL when a transaction is submitted. That fee is separate from the amount a service collects, which could be denominated in another token.

A wallet holding enough stablecoins to pay an invoice can still fail to send it if it has no POL for gas. For a recurring payment, the sender needs both the payment asset and a POL reserve.

How should you fund the payment wallet?

Fund the wallet on the same network where the service transaction will execute. Tokens held on Ethereum or another chain do not automatically pay fees on Polygon PoS.

If funds need to move between chains, allow for the bridge’s route and timing before the payment is due. This guide to Polygon Bridge timing by transfer direction explains why the route matters. A bridge transfer is a separate step, and it may require gas on the chain where it starts as well.

What should you check before automating payments?

Confirm which wallet signs the transaction, which chain it uses, and whether the service supports a relayer or gas sponsorship. Some account systems can arrange fee payment through a third party, but that depends on the service’s setup; do not assume it applies to a standard wallet.

What is confirmed is the fee requirement: a Polygon PoS transaction needs gas paid in POL unless its transaction flow explicitly covers that cost another way. What remains open is the timing and total cost of future transactions, which depend on network conditions and the payment path.

For most users, the practical choice is to keep a separate POL buffer in the sending wallet and check it before each payment cycle. Refill it early if funds must cross a bridge, rather than relying on a transfer arriving at the last moment.
