Ready to keep on getting corrupted (8)
I believe the answer is:
poisoned
'corrupted' is the definition.
(poisoning is a kind of corrupting)
'ready to keep on' is the wordplay.
'ready' becomes 'poised' (as in being poised to do something).
'to keep' means one lot of letters goes inside another.
'poised' going around 'on' is 'POISONED'.
'getting' acts as a link.
(Other definitions for poisoned that I've seen before include "Administered a toxin" , "Administered venom" .)
