If ANY valid medium severity issue is found, contest pot increases to $430,000. Note that not all offer items need to be spent. This is a JavaScript library intended to make interfacing with the contract reasonable and easy. As validated orders may still be unfulfillable due to invalid item amounts or other factors, callers should determine whether validated orders are fulfillable by simulating the fulfillment call prior to execution. If ANY valid medium severity issue is found, contest pot increases to $430,000. If nothing happens, download Xcode and try again. Owned by C8E43D. Use Git or checkout with SVN using the web URL.
