Arbitrum Wallets and the Polygon to Base Route

Why this matters on Arbitrum

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.

Arbitrum is an Ethereum Layer 2 environment with its own balances and application ecosystem.

Arbitrum is part of the Ethereum scaling ecosystem. The same ticker can exist on Ethereum and on Arbitrum 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.

Arbitrum and this route

Arbitrum is neither end of the Polygon to Base route, but a wallet that uses Arbitrum often holds balances on those networks too. If your assets are on Arbitrum, they would first have to be on Polygon for this route to apply.

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.

Arbitrum: what to pay attention to

• Costs: Compare L2 transaction costs with any bridge or liquidity costs required to reach the destination.
• Security: Verify the network, contract and destination before signing cross-chain transactions.
• Assets and tokens: Confirm the Arbitrum token contract rather than assuming an identical ticker represents the same asset everywhere.

A Arbitrum checklist for this topic

• Do not assume a route from Arbitrum is available; check the current interface and quote.
• Send a small test amount first if the route or address is new to you.
• Confirm that the token you hold on Arbitrum is supported for the route you are reading about.
• Verify the source network, the destination network and the destination address before signing.

Bridge from Arbitrum

Compare L2 transaction costs with any bridge or liquidity costs required to reach the destination. On the Base side: verify the token contract on Base and do not rely on ticker or logo alone.

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