Address screening should fit into the RPC flow you use.
`ofac_check` checks an address against the latest OFAC SDN list via your Quicknode endpoint.
The list refreshes daily, with versioned artifacts and detached signatures for verification
If you call `eth_signTransaction` and get `unknown account`, it doesn't mean your endpoint is broken.
The endpoint can't sign because it doesn't hold your private key. Sign locally, then send the signed bytes with `eth_sendRawTransaction`.

Good research needs complete data. Pumped to be powering @RefractionRWA's coverage of the RWA scene on Robinhood Chain and Hyperliquid's RWA DeFi sector.
Excited to announce that @Quicknode is now supporting our research.
This enables us to begin covering the vastly expanding RWA scene on Robinhood chain as well as building out coverage for Hyperliquid's RWA DeFi sector.
Expect to see insights on these ecosystems soon
Early-stage teams have enough unknowns. Blockchain infrastructure should not be one of them.
Our Startup Program provides eligible teams with product credits and direct technical guidance so they can focus on building their product.
