Limits

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.
