A Fast Check When a Base Exchange Won’t Load

Base exchanges rely on a website, a connected wallet and a Base RPC endpoint to show markets and submit swaps. If one will not load, check those layers before assuming the network is down.

• Base Mainnet chain ID: 8453
• Base Mainnet hexadecimal chain ID: 0x2105
• Base Sepolia testnet chain ID: 84532

Where should you start when a Base exchange fails to load?

First, check whether the exchange’s website loads at all, then see whether other Base apps work. If the page opens but its markets or balances do not, the fault may sit between the app and its RPC provider, which carries requests to the chain.

For the steps involved in trading and providing liquidity, baseswap has a fuller walkthrough. A loading problem is a separate issue: the site can be unavailable even while Base itself continues producing blocks.

How can you tell whether Base or the exchange is down?

Compare the exchange with Base’s official status page. At the time of writing, it lists the mainnet, public RPC API and website as operational.

That is confirmation about the services listed there, not a guarantee that every exchange or internet connection is working. If the status page reports an incident, a site failure may reflect a wider service problem. If it shows operational systems while one exchange remains stuck, the issue is more likely local to that app, its RPC route or your connection.

What should you check in your wallet?

Confirm the wallet is connected to Base Mainnet, whose chain ID is 8453, or 0x2105 in hexadecimal. A wallet pointed at Base Sepolia, the test network, will not show the same mainnet balances or markets.

If other apps work, refresh the exchange and reconnect the wallet. A different RPC endpoint can help diagnose a stalled connection, but changing it affects how the wallet reads network data; it does not move funds or fix a broken exchange site.

Before submitting again, check the wallet for a pending transaction. A slow page does not prove the first request failed, and repeating a swap could create a second transaction. The confirmed checks are the status page, the wallet network and whether other Base apps load. Which component caused the failure can remain open until those comparisons narrow it down.
