# Functions which are still considered slightly experimental
Ranked by danger.
* **Core.buildDepositProof(s)** ➡️ because we still need more testnet tests. Will most likely not break, but watch out with token withdrawals, until we have a testnet confirmation.
* **Relayer.handleWithdrawal** ➡️ because no test relayer has been yet available to handle this. Will likely break.
* **Core.loadNotes** ➡️ more tests are needed on filtering behaviour. Likely won't break.
