When adding a new key pair to an existing account, how much RAM, CPU, and NET is required?

1 Answer 1


Testing with v1.5.1, adding a new permission to an account (set account):

Corresponding contract action: updateauth

RAM: 32 bytes NET: 185 bytes CPU: 320 time

for set action permission:

Corresponding contract action: linkauth

RAM: 144 bytes NET: 127 bytes CPU: 664 time

Important to know:

Ram usage is about using the storage, that means if update a permission (modifying a table index) it won't use additional ram.

From my experience, CPU usage fluctuates slightly.
