PraxDevnet
The marketplace for expiring AI credits

Your unused AI credits
are worth real money.

Enterprises prepay for Claude, GPT-4o, Gemini, and routinely burn less than half before the commit expires. Solo developers and startups need that capacity right now, at half the price. Prax is the exchange that connects them. Solana settles every trade in 400ms.
