Evernode's plan to introduce Hooks and a new token, Codii, to the XRP Ledger (XRPL) to enhance programmability has been questioned by Ripple CTO David Schwartz. Schwartz believes that the plan is too complicated and has no obvious benefits, and warns that it may push up transaction fees across the network due to increased resource requirements. Evernode co-founder Scott Chamberlain proposed that Codii tokens be used to pay for the execution of Hooks, but Schwartz advocated that XRP should be used directly to simplify the system and avoid unnecessary fee increases.
