As the Pokemon Trading world continues to grow and hacks become popular, it it important to have some form of proof to show the legitimacy of your Pokemon to interested traders. This wiki serves to guide neoseekers (especially event collectors) about the role of proofs in the trading community.
 What does proof do?
Not only does proof add credibility to your Pokemon, it also enhances the value of said Pokemon because you have proved the Pokemon to be legitimate. You will often come across traders who are willing to offer more for a Pokemon that comes with certain proof. Do note that there is no way to prove a Pokemon to be uncloned although you can prove it to be legitimate.
 Which Pokemon should come with proof?
Uncloned event Pokemon should almost always come with proof because PowerSaves, the 3DS Action Replay, is able to inject fake wondercards into your game for event Pokemon having a specific date. Other save editors like the Japanese Cyber Gen is also able to produce fake event Pokemon. Uncloned events are some of the most valuable Pokemon that exist because of their rarity and high demand. Cloned event Pokemon may also come with proof of legitimacy because of the aforementioned reasons.
As PowerSaves can shinify and PKHeX can edit your Pokemon, proof of legitimacy for shiny Pokemon is essential to have if you intend to put the shiny up for trade. If you caught or hatched a shiny Pokemon yourself or through a Shiny Value Exchange, proof will enhance the shiny's value.
Proof for competitive Pokemon is not required because there is no way to prove whether the IVs or Poke Ball of a Pokemon have been edited or not. In this case, it is advisable to trade with breeders/traders who have been on Neoseeker for a reasonable time and claim to offer legitimate Pokemon.
Proof for items is non-existent in today's world. There is no point to ascertain whether an item or mega stone was obtained via legal in-game means because PowerSaves is able to generate an unlimited number of items. If you are worried about the item being illegally obtained, you may ask the Original Trainer to take a picture of the player obtaining the item in-game. Unfortunately, items have the least value in terms of trading and requesting proof for them may seem like a wastage of time.
 What kinds of proof can I offer for my event?
 Proof of Trade Thread
This is simply a link to a trade thread, clearly showing the usernames of and the agreement between two traders and the trade taking place. If the trade conversation took place in a PM, the proof would be screenshot(s) of the PM thread. Example.
 Proof of Origin
This includes the name of the website where the event Pokemon was first traded and the usernames of the traders who the event was passed on to e.g. "This Mirai Minato Pikachu originated on Neoseeker and was obtained by member A who passed it to member H > member L > member P > member X and then to me.
 Proof of Wondercard
This includes a picture of the wondercard of the event Pokemon, clearly showing the top and bottom screens of the 3DS. This should be accompanied by the username of the Original Trainer (OT) hand-written on a piece of paper and placed beside the 3DS in the picture(s) taken. Example.
 Proof of Redemption
This includes pictures taken of the event redemption process accompanied by the username of the Original Trainer (OT) hand-written on a piece of paper and placed beside the 3DS in the picture(s) taken. Example album.
 Video Proof
This includes a video taken of the redemption process,showing the wondercard accompanied by the username of the Original Trainer (OT) hand-written on a piece of paper and placed beside the 3DS in the video taken. Example.
 Proof of Attendance
This includes pictures of your surroundings if it is a real-life event. The proof shows your presence at the event location although it may not show a picture of you. Example.
 Proof of Game Save
This includes a picture of your save file, accompanied by the username of the Original Trainer (OT) hand-written on a piece of paper and placed beside the 3DS in the picture(s) taken. Example.
 Proof of Serial Code
 What is the most reliable kind of proof for an event?
The most reliable kind of proof would have to be a video taken of the redemption process where you can see the event being downloaded, followed by the wondercard of the event and accompanied by the username of the Original Trainer (OT).
 I don't have any/sufficient proof. Is my Pokemon worthless?
Not at all. Just because your legitimate Pokemon does not come with proof does not make it worthless. It is still legitimate so it has some value. As mentioned earlier, competitive Pokemon and items may not be accompanied by any kind of proof and still hold sufficient value.
 What are some proofs which I should be wary of?
Picture proof that is cropped out, censored or hidden in some way should make you wary of the Pokemon being offered. It is very easy to take someone else's picture proof and crop out a portion of the picture to use the picture as your own. Example 1. Example 2.
Secondly, picture proof that does not contain a piece of paper with a trader's (user)name on it is also suspicious. When offering an uncloned event that you obtained yourself, write your username (essential) and the username of the person you're trading the event to (optional) on a piece of paper and place that paper near your 3DS before taking pictures of the wondercard and/or redemption process. By doing this, you take responsibility for the event you offer. Taking responsibility for your event is one of the reasons why people trust you and propose a trade. Usernames also help trace the origin of the event, leading you to the original Trainer (OT).
When dealing with suspicious proof, the first thing to do is to ask the trader his/her reasoning for cropping out the picture and/or not having any usernames in the picture. Please try your best to maintain professional behaviour while discussing this. Flaming someone for stealing proof or passing on a hack is unacceptable. Take a minute to PM the Trading/Shopping District forum moderator(s) about this.
 Where should I store all of my proofs?
When someone offers you proof, it is often uploaded to safe sites like Imgur or Dropbox. It is advised to download the proof to your computer as soon as you receive it in case the trader deletes the proof later, which is normal considering they no longer have the event so it is useless to retain the proof. Sometimes, however, people may upload proof to tinypic or other file hosting websites where the picture is automatically removed after a certain time period.
 What if someone steals my proof and uses it as their own?
As event Pokemon continue to pour in, it is possible for two event Pokemon to have almost identical proof. This is why traders are encouraged to offer different kinds of proof and use usernames in the proof to show the Original Trainer (OT) of the Pokemon and original recipient said Pokemon was initially traded to. Traders are also advised to post URLs leading to their proofs after a trade agreement has been reached. In the event of a mishap or argument, contact the forum moderators immediately.
