# hooks-raddr-conv-pure

Hooks identify accounts by the 20 byte account ID, which can be converted from a raddr using the [util_accid](https://xrpl-hooks.readme.io/v2.0/reference/util_accid) function. If the raddr never changes, a more efficient way to do this is precompute the account-id from the raddr.

This check warns about calls of `util_accid` with constant input and proposes to add a tracing statement showing the computed value (so that the user can use it to replace the call).
