Inspiration

The Solana NFT ecosystem is booming, and with all the auctions an average person participates in, it's easy to forget some where you bid and lost (non-winning bids have to be redeemed manually after the auction end.)

This is especially true for the June-July period, where it all was new and $SOL was cheap.

What it does

When you enter a wallet address, you get a list of bids that you didn't win and have yet to redeem. You can redeem them with one click directly from the interface.

How we built it

I built the tool using my Solana Go SDK and my Go Metaplex library.

Challenges we ran into

The bid redemption instruction involves a lot of PDAs (program derived addresses). The most challenging part was getting all the needed PDAs right.

Accomplishments that we're proud of

It's a fast experience that doesn't rely on remembering all the auctions you might have bid on, or searching and loading each Metaplex auction page to redeem a lost bid.

What we learned

• Processing a significant amount of data needs to be done very efficiently.
• Everything makes sense if you take a look at the (Metaplex) code.

What's next for Metaplex Lost Bid Redeemer

Metaplex lost bids was the start; there are many more similar issues where access to a certain user-desirable action is fragmented among many pages and places, and not easily reachable.
