QUICKTXN / DOCUMENTATION
Build with QuickTxn
Sign with your wallet. Submit through a QuickTxn edge. Verify the result on your chain.
Managed access
Robinhood Chain mainnet is available through existing customer onboarding. Regional expansion and the new hmqt- key format are rolling out. Use the endpoint and credential assigned to your account until your migration is confirmed.
One product, explicit chain access
QuickTxn is a Hello Moon transaction submission service with its own endpoints and customer credentials. A QuickTxn credential does not grant Sherwood Express access. Chain permissions are assigned separately.

The new isolated QuickTxn rollout enables Robinhood Chain only. BSC, Solana, public QUIC, bundles, and UserOperations are outside this QuickTxn launch.
The integration boundary
- Read state, estimate gas, and obtain the nonce from your chain RPC.
- Build the transaction with your assigned fee policy and sign in your wallet.
- Send the signed bytes to the assigned QuickTxn HTTPS endpoint.
- Read the receipt from your chain RPC. A submission response alone is not confirmation.
