Tokens have an expiry of between 10 seconds and 24 hours.
Beyond this, seller services have a 24 hour grace period to charge tokens they receive.
Full settlement of a token takes place after the expiry of the grace period within a 3 hour window.
Settlement of payments can therefore take up to 51 hours.
However, when seller services make charges on tokens, these charges become eligible to settle sooner if they total more than $1.00.
As soon as the cumulative charges on a token total more than $1.00 they settle within the 3 hour window.
