Jupiter the first on-chain swap aggregator is now live on Solana. They claim that their main goal is to provide the best rates by routing across all major liquidity markets, while giving users and developers the best swapping experience in all of DeFi.

Currently, Jupiter covers Project Serum, Raydium Protocol, MercurialFi, and staratlas.  In the forth coming weeks they will be integrating orca_so, Saber_HQ, and Step Finance and further several other major markets will be integrated.

Jupiter is focused on best integrations, best rates discovery and split transactions with best in class UX for user-friendliness, seamless integration with any website and fun API that takes the pain and issues out of swaps (and dark mode).

Swap aggregation actually works extremely well on Solana due to the hyper fast transaction speed. And of course, the extremely low fees mean that you don’t need to give up your firstborn to use an aggregator. Keep the babies (tokens) safe.

The Jupiter aggregator team will be sharing more about their vision, detailed roadmap and growth plans in coming weeks.  They will also be giving away exclusive NFTs, and drops to early followers and members. They are looking forward to build the best aggregator in DeFi together.

Community response:  I tried 4 times, I lost 0.1sol without getting anything in return. I feel robbed for trying to support this project.

The transaction attached shows that an openOrder Account was created and 0.02335776 SOL was deducted as ‘rent’ for this account. This is a Serum fee and not charged by us. You can close the account and reclaim the fees.

Unlike AMMs, when swapping thru Serum’s DEX, you need to pay rent to create OpenOrder accounts regardless if the swap succeeded. This rent is reclaimable. The swaps were halted because of slippage limits.

Unlike an AMM with a deep liquidity pool swapping on a dex mean looking at the open orders for the best price. But the best priced orders, are the most likely to get filled before you complete your swap and the next best order may not fit your slippage limit.

Expensive fees and very difficult to swap.

I’m sorry to hear about your experience! We’re working to make things much clearer, but, the “high fees” is just the rent needed to create the token accounts to trade on Serum. You can reclaim them at any time by closing the accounts.

What is the difference between swap in the wallet or exchange compare to?  The swap in your wallet or on an exchange typically only looks in one AMM or DEX to do your swap. So if you wanted to get best priced swap you’d have to check each AMM/DEX for the best price. Jupiter Aggregator will do this automatically for you.
