Attestations

Request a Soft Attestation Quote

A soft quote provides pricing information for mint or redeem operations without creating an actual attestation. Unlike the Request a Mint or Redeem Attestation endpoint, soft quotes:

  • Are not eligible for on-chain submission
  • Do not count against user limits (Active Notional Value, Session Notional Value, or Active Attestations)
  • Serve as pricing references for quote validation and user interface display
  • Do not include authentication fields such as attestationId, userId, expiration, or signature

This endpoint can be used to acquire estimated pricing without impacting trading limits or creating binding commitments.
