| Aug 23, 2018 at 1:22 | comment | added | Tjaden Hess | Once you get the whole thing figured out, it would be nice if you could post an answer with what you found out, to help future users | |
| Aug 22, 2018 at 21:27 | comment | added | Nico Vergauwen | so sload(<position>) won't work because it's a struct. I figured that out I think. | |
| Aug 22, 2018 at 19:43 | comment | added | Nico Vergauwen | Still facing an empty array being returned :( ethfiddle.com/p0PdFSXF4v && ethfiddle.com/7_7N8SuhF2 | |
| Aug 22, 2018 at 17:22 | comment | added | Nico Vergauwen | Thanks I think I can manage now. Cool that will help me on my way! I just need to split calldatacopy at the 4th byte (ending of the signature) and put my _bounty in between. I'll try figuring something out later tonight. Thanks for the help! | |

calldatacopy(add(_message, 36), 100, sub(calldatasize,100)) or something similar workshould

| Aug 22, 2018 at 17:09 | comment | added | Nico Vergauwen | But I can't just do calldatacopy(_message, 0, calldatasize) , can I ? Wouldn't that overwrite the _sig and _bounty already stored in memory there? Here are all the contracts for a little more context: gist.github.com/kyriediculous/fd070786ce981a64a981e73487ba73ec | |
| Aug 22, 2018 at 17:04 | comment | added | Tjaden Hess | calldatacopy can copy to anywhere in memory, including copying right after storage | |
| Aug 22, 2018 at 17:00 | comment | added | Nico Vergauwen | The isue with calldatacopy is that I would need to encode my storage before the calldata still. I'm not sure this is possible that way? So I essentially need to construct a new message in my forward function consisting out of Signature + Storage + Calldata | |
