Chains ​

Requests will be responded to after minConfirmations blocks (see On Slow and Fast Block Times to learn more). Expect this to correspond to 1–3 minutes based on chain conditions such as congestion and block times. These numbers are subject to change.

You can import AirnodeRrpV0 addresses from the @api3/airnode-protocol package, see the QRNG example project. The @api3/airnode-protocol package is distributed via npm.

Testnet Random Numbers imitates QRNG using pseudorandom numbers and is best used during development. Use ANU or Quintessence in production to acquire quantum random numbers.

ANU ​

ANU is only available on mainnets.
