Function encode_wrapper_settlement

crates/simulator/src/encoding.rs:281–298

Encodes a settlement transaction that uses wrapper contracts. Takes the base settlement calldata and wraps it in a wrappedSettleCall with encoded wrapper metadata. Since wrappers are a chain, the wrapper address to call is also processed by this function. Returns (first_wrapper_address, wrapped_calldata)

    wrappers: &[WrapperCall],
    settle_calldata: Bytes,
)
