}'Frequently Asked Questions
Does BlockReq support Base archive nodes?
Yes. BlockReq provides full archive nodes for Base (Coinbase L2), supporting all historical state queries, eth_getProof, and debug/trace methods on any block since genesis.
Is Base Sepolia testnet available?
Yes. Both Base Mainnet and Base Sepolia are available with archive node support, making it easy to develop and test before deploying to production.
Can I fork Base mainnet for local development?
Yes. Use BlockReq's Base archive endpoint with Hardhat or Foundry to fork from any historical block. All state data is preserved, so contract simulation and debug_traceTransaction work on any past transaction.
