- Gas and approvals
- Keep POL on Polygon for network fees. POL is the native asset here, so spending it does not need an ERC-20 approval. Leave some behind for gas. To spend the received ETH later on Base, you will need ETH there for gas.
- Compare an executable quote
- Disconnected previews request current provider quotes but cannot be signed. Reference-price tables are separate from those quotes. Connect your wallet to get transaction details for your address. Review the provider, fees, recipient and minimum received for your amount before signing.

What to review before bridging to Base
Compare the expected ETH output and minimum received on Base. Keep POL for separately paid source gas and check any bridge or provider fees. A route with more output does not necessarily have the lowest total cost after gas.
SwapRoute requests quotes from capable 0x and Relay integrations in parallel. Returned routes are ranked by net token output; provider confidence only breaks effectively equal outputs. Speed is not part of the ranking. Availability can change with the amount and market conditions.
FAQ
Polygon to Base bridge — FAQ
How do I bridge from Polygon to Base?
Choose Polygon as the source chain and Base as the destination chain, enter an amount, then review the best available route before signing in your wallet.
How long does a Polygon to Base bridge take?
Timing depends on provider liquidity and conditions on Polygon and Base. A provider's estimate is not a measured completion time or a guarantee. Track the destination transaction; source-chain confirmation alone does not confirm arrival.
Can I send bridged funds to a different wallet?
You can request a different recipient on the destination network when the provider supports it. ETH/WETH wrapping can require the connected wallet as recipient. Verify the destination network and address before signing.
Does SwapRoute custody funds while bridging?
No. SwapRoute is non-custodial. You connect your wallet, review the transaction, and sign directly. Execution is handled by the underlying route provider and protocols.
