OP_RETURN outputs are frequently used for placing arbitrary data on-chain.

As this is generally used for creating unspendable outputs, no unlocking script is defined on this contract.

Lock parameters

• :data - A single binary or list of binary values.

Examples

iex> contract = OpReturn.lock(0, %{data: "hello world"})
iex> Contract.to_script(contract)
%Script{chunks: [
  :OP_FALSE,
  :OP_RETURN,
  "hello world"
]}

iex> contract = OpReturn.lock(0, %{data: ["hello", "world"]})
iex> Contract.to_script(contract)
%Script{chunks: [
  :OP_FALSE,
  :OP_RETURN,
  "hello",
  "world"
]}
