Hello, I am using the V3 SDK to getting a quote. It uses the 0xb27308f9F90D607463bb33eA1BeBb41C27CE5AB6 Quoter Contract on the Ethereum Mainnet for querying quotes.

However, I cannot find which Quoter Contract should be used on the Sepolia testnet?

Please kindly let me know.

// constants.ts
export const QUOTER_CONTRACT_ADDRESS =  '0xb27308f9F90D607463bb33eA1BeBb41C27CE5AB6'

// [quote.ts](https://github.com/Uniswap/examples/blob/main/v3-sdk/quoting/src/libs/quote.ts)
const quoterContract = new ethers.Contract(
  QUOTER_CONTRACT_ADDRESS,
  Quoter.abi,
  getProvider()
)

@liubin595338764 here's the list:
https://docs.uniswap.org/contracts/v3/reference/deployments

Also, why I'm here, maybe you or anyone else knows which addresses should be used for tokens?

Uhm, thanks, truly !! Forgive me for asking though, I am not sure how to quote from the mentionned contract, it really is a Factory contract, isn't it ?

The address named as the Sepolia Quoter contract in the documentation is incorrect. In fact, this address does not contain a deployed contract. Therefore any attempt to call the Quoter methods will revert. I hope the Uniswap team will publish the correct address.
