Smart Contract's development on Elixir using Orb

[vlmoon99]

I wrote a low-level smart contract as a proof of this toolkit’s ability to compile code into a small WASM file, deploy it, and execute it on the chain: #49.

I’m interested in your opinion on this work and the approach.

example of low-level smart contract on Elixir + Orb

defmodule Env do
  use Orb.Import, name: :env

  defw input(register_id: I64)
  defw log_utf8(ptr: I64, len: I64)
end

defmodule NearElixirExample do
  use Orb

  Memory.pages(1)

  Orb.Import.register(Env)

  defw log_hello_world(), slice: I64, offset: I64, length: I64 do
    Env.input(18446744073709551614)

    slice = Orb.Str.to_slice("Hello World")

    offset = Orb.Memory.Slice.get_byte_offset(slice) |> I64.extend_i32_u()
    length = Orb.Memory.Slice.get_byte_length(slice) |> I64.extend_i32_u()

    Env.log_utf8(offset, length)
  end
end
