Understand Polygon Gas Fees

A Polygon PoS transaction typically costs $0.0001–$0.001 for a simple POL transfer and $0.001–$0.01 for a DeFi swap in normal conditions. These figures assume a 30–100 gwei base fee and POL priced at $0.20–$0.80. Even during brief congestion events, Polygon fees rarely exceed a few cents — far below Ethereum mainnet levels.

Gas on Polygon PoS is paid in POL, the native token formerly known as MATIC. In 2024, Polygon completed its 1:1 token migration from MATIC to POL as part of the Polygon 2.0 upgrade. If your wallet still shows MATIC, it is the same token — POL and MATIC are interchangeable at a 1:1 ratio after the migration.

Yes. Polygon PoS adopted the EIP-1559 fee model in its London-equivalent hard fork. This means each transaction has a base fee that adjusts algorithmically per block (targeting 50% utilization) plus an optional priority tip. The base fee is burned in POL. The EIP-1559 model makes fees more predictable than a pure gas-price auction.

Polygon PoS is a sidechain, not an Ethereum rollup. It runs its own proof-of-stake validator set and periodically checkpoints its state to Ethereum, but it does not post full transaction data to Ethereum as blobs (EIP-4844) the way Ethereum rollups like Arbitrum, Optimism, or Base do. This means Polygon PoS does not inherit Ethereum's full data-availability security — it relies on its own validators.

Polygon fees are low primarily because POL (the gas token) trades at a far lower price than ETH, not because the gwei figures are dramatically lower. A 100-gwei transaction on Polygon might cost $0.001, while the same 100 gwei on Ethereum mainnet costs far more because ETH is priced much higher. Additionally, Polygon's PoS sidechain design processes more transactions per block than Ethereum mainnet, reducing per-transaction costs.

Bridging from Ethereum mainnet to Polygon costs standard Ethereum gas, not Polygon's sub-cent rate, because the deposit step itself is an Ethereum L1 transaction — expect the same few-dollars-to-$20-plus range that any Ethereum mainnet transaction costs depending on congestion. Once your assets have actually arrived on Polygon, every transaction after that reverts to Polygon's normal sub-cent fees described above. Use the official Polygon Bridge linked from polygon.technology rather than a third-party bridging service, since it's the canonical, audited route between the two chains.

There are two practical paths. First, buy POL on an exchange that supports direct withdrawal to the Polygon network, and send it straight to your wallet address on Polygon — check your exchange's withdrawal screen for a Polygon or POL network option before sending. Second, if you already hold ETH, use the official Polygon Bridge linked from polygon.technology to bridge ETH from Ethereum mainnet to Polygon, then swap a portion for POL once it arrives. The exchange-withdrawal route is usually simpler if the exchange supports it directly.

Polygon's base chain itself has not suffered a hack where an attacker drained user funds directly. Its bigger security tradeoff is structural: Polygon trusts its own validator set rather than inheriting Ethereum's full security, since it's a sidechain, not a rollup — a meaningfully different trust model than an Ethereum L2 like Base or Arbitrum. Polygon's bridge contracts have had vulnerabilities found and patched through responsible disclosure before they were exploited at scale, which is normal for actively audited infrastructure but still a reminder that a bridge carries its own separate risk from the base chain. Any DeFi app built on top of Polygon carries further smart-contract risk on top of both of those layers.

No, they're not always this low — Polygon's base fee adjusts algorithmically to target 50% block utilization, so fees rise when demand pushes blocks above that target and fall when it drops below it. During periods of high network demand, expect the gwei figure to climb above its typical 30–100 gwei range, the same way any EIP-1559 chain responds to congestion. The exact multiple during a spike isn't fixed and depends on how far above target the network runs, so check Polygonscan's gas tracker for the current reading rather than assuming a static rate.

Polygon, Base, and Arbitrum are all in the sub-cent-to-low-cent range for typical transactions, but they get there through different architectures — Polygon runs its own validator set as a sidechain, while Base and Arbitrum are Ethereum rollups that post data back to Ethereum. See /fees/crypto-network-fees for a fuller side-by-side comparison to help decide which network fits a given DeFi transaction.

Any standard EVM-compatible wallet works for holding POL — see /learn/what-is-a-crypto-wallet for how wallets work and how to choose one. Just make sure the Polygon network is added in your wallet's network settings before you try to send or receive POL, since the wrong network selected will send funds to the wrong place.

No — like nearly all blockchain transactions, a Polygon send is final once confirmed, so sending to the wrong address or the wrong network isn't something you can undo from your end. See /fix/recover-crypto-wrong-network for what limited recovery options actually exist and the realistic odds of getting funds back.
