Polygon to Base Route: Base Wallet Guide

Why this matters on Base

Polygon-to-Base is a cross-chain move, even though both ecosystems support many familiar assets. Confirm the exact destination representation before using the received balance.

Base is an Ethereum Layer 2 environment with its own network balances, applications and token representations.

Base is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Base as separate token contracts, so a balance seen on one network cannot be assumed to exist, or to be redeemable at the same value, on the other.

Base and this route

Base is the destination for this route. Before receiving assets from Polygon, confirm the token you expect to receive on Base.

Leaving Polygon

Compare Polygon transaction costs with bridge and liquidity costs when consolidating small balances. Check network selection and contract addresses before signing, especially when an asset also exists on Ethereum.

Arriving on Base

Verify the token contract on Base and do not rely on ticker or logo alone. Consider Base transaction costs together with bridge and route costs when moving small balances.

Base: what to pay attention to

• Costs: Consider Base transaction costs together with bridge and route costs when moving small balances.
• Security: Use trusted interfaces and verify destination network and token before signing.
• Assets and tokens: Verify the token contract on Base and do not rely on ticker or logo alone.

A Base checklist for this topic

• Confirm that the token you hold on Base is supported for the route you are reading about.
• Verify the source network, the destination network and the destination address before signing.
• Compare quotes and the minimum received amount, since the final amount can differ from the estimate.
• Keep enough native balance on the source network to pay for the transaction.

Bridge from Base

Consider Base transaction costs together with bridge and route costs when moving small balances. On the Optimism side: verify the Optimism contract address for the asset you intend to move.

The bridge guide below is informational; any transaction depends on current network conditions and the route shown in the bridge interface.
