### I keep seeing a smart contract with the address `0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee`. What is this address?

The address 0xeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeeee is a sentinel (placeholder) address used to represent native tokens in EVM smart contracts. Since native tokens (ETH, BNB, AVAX, etc.) exist at the protocol level rather than as smart contracts, DeFi protocols need a placeholder address when their code expects contract addresses for all tokens. This address represents the native token of whatever chain you're on: ETH on Ethereum and its L2s (Base, Arbitrum, Optimism), BNB on BSC, AVAX on Avalanche, FTM on Fantom, and so forth. The repetitive pattern makes it obvious that the address is artificial; it's not a real account anyone controls, just an arbitrarily chosen low-entropy address that developers agreed to use.

### I'm getting 403/401 errors. What's wrong?

Check that you included the `Authorization: Bearer <jwt>` header with the correct, non-expired token. Common issues include using the API key instead of generating a new JWT, forgetting the "Bearer" prefix, using an incorrect token, or omitting the header entirely. Ensure you copied the JWT exactly as provided by The Graph Market.

### How do I specify a network?

You can query available networks with [this link](https://token-api.thegraph.com/#tag/monitoring/GET/networks). A full list of the exact network IDs accepted by The Graph can be found on [The Graph's Networks](https://thegraph.com/docs/en/supported-networks/). Use the optional `network_id` parameter (e.g., `mainnet`, `bsc`, `base`, `arbitrum-one`, `optimism`, `matic`, `unichain`) to target a specific chain. Without this parameter, the API defaults to Ethereum mainnet.
