Bonds should be redeemable by using them on another player, bypassing the trade screen. It's functionality would be similar to that of a Christmas cracker.
You may be asking, "Why implement this when we can already trade bonds?". The answer to this, is Iron Men. We're unable to get bonds any other way than actually donating, and this isn't always feasible due to personal income situations. As of right now, the only way for an Iron Man to get a bond besides donating is to allow someone else to access our forums account and then they purchase the bond on the account. This is unacceptable as it puts our accounts at risk. Implementing the "Use on Player" functionality provides a safe alternative for Iron Men who are looking to get donator status.
This will benefit the server by providing a safe way for Iron Men to be able to purchase bonds from other players.
The only other way I can see this working is by allowing Iron Men to use the Trading Post, but only allowing Bonds to be purchased.
