Polygon to Base Bridge
There is no official bridge that goes straight from Polygon PoS to Base. Fast bridges like Across and Relay move USDC and ETH between them in seconds, and Circle CCTP moves real USDC. Going through Ethereum with the official bridges also works, but it takes hours and costs more.

Short answer
Polygon PoS and Base are both EVM networks, so your wallet address is the same on both. They are built in different ways, though. Polygon PoS is a proof-of-stake chain with its own validators and pays fees in POL. Base is an Ethereum layer 2 and pays fees in ETH.
Neither official bridge connects them. The Polygon PoS bridge and the Base standard bridge each only connect to Ethereum. So you either go through Ethereum with two bridges, or you use a third-party bridge that pays you on Base directly.
For almost everyone, the direct third-party route is the right one. This page shows the main options, the gas and USDC details that trip people up, and a step-by-step example of moving USDC from Polygon to Base.
| Direct official bridge | None |
|---|---|
| Official route via Ethereum | Usually a few hours, plus a deposit into Base |
| Fastest option | Intent bridges, seconds |
| Real USDC | Circle CCTP |
| Fees on Polygon paid in | POL |
| Fees on Base paid in | ETH |
Why this route is difficult
Polygon PoS and Base are separate networks with different security models. Polygon PoS is secured by its own validators, who post checkpoints to Ethereum. Base is a rollup that posts its data to Ethereum. Each official bridge only moves funds between its own chain and Ethereum.
Taking the official path means two trips. Leaving Polygon through the PoS bridge means burning tokens, waiting for a checkpoint on Ethereum, which usually takes a few hours, and then sending an exit transaction on Ethereum. Only then can you deposit into Base, which usually takes a few minutes.
Fast bridges solve this by fronting the money. A relayer or solver pays you on Base from its own balance and gets repaid later. For USDC, CCTP works another way: it burns native USDC on Polygon and Circle mints the same amount on Base.
Possible approaches
1Two official bridges via Ethereum
Withdraw from Polygon to Ethereum through the PoS bridge, then deposit into Base through the standard bridge.
Trade-offUses only the official bridges, but takes hours and needs ETH on Ethereum for two transactions.
2Intent-based bridge
You lock funds on Polygon, and a relayer or solver pays you on Base right away.
Trade-offSeconds and low cost, but you rely on the bridge's own contracts and repayment system.
3Issuer burn-and-mint
Circle CCTP burns your USDC on Polygon and mints real USDC on Base.
Trade-offReal USDC with no pool limits, but it only works for native USDC.
4Exchange deposit and withdrawal
Deposit on Polygon to an exchange account and withdraw on Base.
Trade-offSimple if you already have an account, but the exchange holds your coins in between.
Options compared
| Option | You get | Typical time | Cost | Best for |
|---|---|---|---|---|
| Official bridges through Ethereum | ETH or official tokens on Base | Usually a few hours to exit Polygon, then a few minutes into Base | Polygon fee + Ethereum exit fee + Ethereum deposit fee | Rare cases where you only trust the official bridges |
| Intent-based bridge (Across, Relay) | USDC, ETH and other common tokens | Usually seconds | Network fee + small bridge fee | Most transfers |
| Circle CCTP | Real USDC on Base | Standard mode, which Circle says is already fast from Polygon | Network fees, plus any fee from the app you use | Larger USDC amounts |
| Via an exchange | Coins the exchange lists on Base | Depends on the exchange | Exchange withdrawal fee, if any | People who already use the exchange |
Working solutions
| Solution | You receive | Custody / verification | Notes |
|---|---|---|---|
| Across | USDC, ETH and others | Oracle-checked payback | Lists both Polygon and Base. Usually done in seconds. |
| Relay | USDC, ETH and others | Solver pays you | Fast for common coins. |
| Circle CCTP | Real USDC | Circle attestation | Standard mode from Polygon PoS. Native USDC only. |
| LI.FI | Depends on the route | Same as the bridge used | An aggregator that compares several bridges. |
| Official bridges via Ethereum | ETH or official tokens | Polygon validators, then Ethereum (bridge contracts) | Hours to leave Polygon, then a deposit into Base. |
How to move Polygon to Base
These steps show how to move USDC from Polygon to Base with an intent-based bridge such as Across or Relay. The checks are the same in most fast bridges and in aggregators like LI.FI.
- 1
Check what you hold on Polygon
Open your wallet on Polygon PoS. Make sure you have the USDC you want to move and a little POL for the Polygon network fee. Check whether your USDC is native USDC or the older bridged USDC.e.
- 2
Think about gas on Base
Fees on Base are paid in ETH. If you only receive USDC, you cannot move it on Base until you have some ETH. Some people bridge a small amount of ETH in a second transfer.
- 3
Open the bridge from its real address
Type the address yourself or use a bookmark. Fake bridge sites are often promoted through search ads. Connect your wallet.
- 4
Pick Polygon as source and Base as destination
Make sure the source is Polygon PoS, not a Polygon test network or another Polygon chain.
- 5
Enter the amount and read the quote
The quote shows the amount you will receive on Base, which already includes the bridge fee. The first time you send a token, you sign an approval and then the transfer.
- 6
Check that it arrived
The bridge usually shows the transfer as done within seconds. You can also look up your address on Basescan.
Fees and timing
Network fees on Polygon are paid in POL and are usually small. Fees on Base are paid in ETH and are also usually low. For a fast bridge, the main extra is the bridge fee, which the app folds into the amount you will receive. Compare that final number between apps.
Circle CCTP has no pools, so the amount does not change the rate. Circle lists Polygon PoS as a source for standard transfers and says fast mode is not needed there because standard attestation is already fast. Apps built on CCTP may add their own fee.
The route through Ethereum looks free because the official bridges add no fee of their own. In practice you pay an Ethereum exit transaction for the Polygon withdrawal and another Ethereum transaction for the Base deposit, and you wait hours. For most amounts a fast bridge costs less in total.
Common mistakes
- Arriving on Base with only USDC and no ETH to pay for the next transaction.
- Bridging USDC.e, the older bridged USDC on Polygon, and expecting real USDC on Base without checking the quote. CCTP works only with native USDC.
- Sending tokens to your own address on Ethereum and expecting them to show up on Base.
- Taking the route through Ethereum for a small amount and paying two Ethereum fees plus hours of waiting.
- Using a bridge site found through an ad instead of the official address.
- Sending from Polygon straight to an exchange deposit address that is set up for Base, or the other way round.
Before you transfer
- For most amounts, an intent-based bridge is the quickest and cheapest choice.
- For larger USDC amounts, a CCTP route gives you real USDC on Base.
- Check whether you hold USDC or USDC.e on Polygon before you pick a route.
- Get a little ETH on Base so you can use what you bridged.
- Your Polygon address is also your Base address, so no new wallet is needed.
Frequently asked questions
No. The Polygon PoS bridge and the Base standard bridge each connect only to Ethereum. To go straight from Polygon to Base you use a third-party bridge, or you go through Ethereum with both official bridges.
With a fast bridge like Across or Relay, usually seconds. Through Ethereum with the official bridges, usually a few hours, because the Polygon withdrawal waits for a checkpoint on Ethereum.
Yes. Fees on Base are paid in ETH. POL is only used for fees on Polygon. If you bridge only USDC, get a little ETH on Base too.
USDC.e is the older bridged USDC on Polygon. CCTP does not accept it. Some bridges do, so check which token you will receive on Base, or swap USDC.e to native USDC on Polygon first.
POL is the gas token of Polygon. Some fast bridges and aggregators can take POL on Polygon and pay you another token, such as ETH or USDC, on Base. Check the quote to see what you will receive.
USDT0 lists Polygon PoS among its networks but not Base. For USDT, compare quotes from fast bridges and aggregators, and check which token you will get on Base.
Yes, if the exchange supports your coin on both networks. Deposit it on Polygon, then withdraw and pick Base as the network. The exchange holds the coins in between.
