Get Session Limits

Provides theoretical maximum asset-specific trading limits for each trading session. These limits are per-user, not global. This API reflects Ondo’s statically defined limits; for dynamic, real-time values, see Get Trading Limits)

Limits:

• The “Max Attestation Count” limits the number of non-expired, non-executed attestations. For example if the limit is 50, and a user has 50 outstanding attestations, they must wait for one to execute or expire before requesting another.
• The “Max Active Notional Value” limit is based on the dollar value of outstanding attestations. That is, if a user has a limit of $1,000,000, and has 30 non-expired, non-filled attestations at a value of $999,000, they will not be able to request another attestation for $1000.
