@lukaisailovic Is it expected for the dapp to build the userOp and then call this API to validate permissions before submission by the co-signer? Or will the co-signer build and submit the userOp?

Yes. The dapp needs to build userOp and sign it first.

Any max-lengths on these fields? E.g. pci maybe max 64 chars or whatever the spec says?
