 echo nscript… | bech32 -d > zap.wasm && wasm-objdump -x zap.wasm

nostrscripts are sandboxed. They can’t do anything other than set boolean flags in your settings atm

 Can it send an http request with my nsec to a third party?

Anyways, here is the script. I don’t know much about WebAssembly, what does the last “data” operations do?

(module
  (type $t0 (func (param i32 i32 i32) (result i32)))
  (type $t1 (func))
  (import "nostr" "nostr_set_bool" (func $nostr.nostr_set_bool (type $t0)))
  (func $f1 (type $t1)
    (drop
      (call $nostr.nostr_set_bool
        (i32.const 1056)
        (i32.shr_u
          (i32.load
            (i32.const 1052))
          (i32.const 1))
        (i32.const 0))))
  (memory $memory (export "memory") 1)
  (start $f1)
  (data $d0 (i32.const 1036) "\1c")
  (data $d1 (i32.const 1048) "\02\00\00\00\0c\00\00\00n\00o\00z\00a\00p\00s"))

 data defines well…. data. In this case its a utf16 string called “nozaps” this is used as an argument to the nostr_set_bool function call:

nostr_set_bool(“nozaps”, false)

This is the entire script
