OpenDEX

Backend for branded trading apps on Solana, Polymarket and Hyperliquid
Steal ideas from our open-source

[OpenDEX @opendex_ws]

We got tired of the crypto space being dominated by giants with million-dollar budgets, so we built OpenDEX.

Got an idea for an app on Solana, Hyperliquid or Polymarket? Build it.

Focus on your product, UX, and whatever makes your idea special. We’ll handle the backend.

[OpenDEX @opendex_ws]

If you have an idea for an app on @solana, @HyperliquidX, or @Polymarket but the onchain data and backend are slowing you down, let’s connect.

We’ll help with market data, realtime streams, wallets and execution (for free).

Let’s ship more apps together.

@ism_sol You can make an automated strategy ppl can subscribe to (they’ll see the tokens bought in the list, but never not the actual wallets)
It’s one of the things we’ve been working on - happy to help out

[OpenDEX @opendex_ws]

@ism_sol @bot @gmgnai @Helius Did you think about making it fully autonomous?

[OpenDEX @opendex_ws]

@solana_devs @ChibaTech_web3 Next step: onboarding middle-schools. Having backend ready must help with that👀

[OpenDEX @opendex_ws]

@r0bre @SolPlay_jonas Bro cooked

[OpenDEX @opendex_ws]

• connected live swaps through a server-side WebSocket → SSE bridge
• made each swap inspectable, down to amounts, addresses and the transaction link

What would you make it build next?

[OpenDEX @opendex_ws]

What happens when you give an AI agent an @opendex_ws API key? We tested it.

With our AI-first docs, it built a read-only FOMO wallet tracker in under 30 mins:

• ranked Solana wallets by 7-day realized PnL
• added a local Following list, keyed by chain and wallet address👇

@magersih @phanesbot would be cool to pull them into one place and show exactly why each bot flagged the token (can help cook it)

[OpenDEX @opendex_ws]

@toibimemeschoi Let’s cook

@nikkideyy OpenDEX 👀 ready to use backend for trading apps on Solana, Hyperliquid and Polymarket, plus an open-source terminal you can steal and customize.

Great meeting fellow Solana builders in Vietnam. Thanks @SuperteamVN for bringing everyone together.

If you’ve been wanting to build on Solana but haven’t started yet, what’s stopping you?

[vibhu @vibhu]

Vietnam is a great option for Solana builders: massive crypto-native population, low cost of living, great food. Easy to travel anywhere in Asia in a few hours.

Was a pleasure to meet Solana teams:

@lpagent_io
@yodlpay
@gopaymoji
@opendex_ws
@Mermailapp
@OnePlan_Travel
@polarislabxyz
@BasalPay_App
+ others (sorry if I forgot!)

Massive shoutout to @SuperteamVN, and many thanks to @LynnWWins, @dieubui2522, and @LavieTran214 for being wonderful hosts in Vietnam.

Hope to be back soon!

@vibhu @lpagent_io @yodlpay @gopaymoji @Mermailapp @OnePlan_Travel Was awesome meeting you. Many thanks for the insights 🔥

Builder ecosystems that should see this:

Solana: @solana_devs @colosseum @RadiantsDAO @Superteam @SuperteamVN @solanamobile @MonkeDAO @SolanaFndn @SuperteamBlack

Hyperliquid: @hl_hackathon @encodeclub @HyperliquidX

Prediction markets: @PolymarketDevs @getdomeapi @Polymarket

[OpenDEX @opendex_ws]

Want to onboard builders on @solana, @HyperliquidX or @Polymarket? This is the way.

Give them one API key for the entire backend and an open-source terminal to fork.

[OpenDEX @opendex_ws]

Claude, please calculate this wallet’s PnL:

@BloomTrading great minds think alike :)

if you want to add Telegram tracking to Bloom, we’d be happy to help set it up through OpenDEX.

[OpenDEX @opendex_ws]

@ChibaTech_web3 Shipping is easier with backend ready - just saying

[OpenDEX @opendex_ws]

the opportunity?

you can spend your weekend building a trading product instead of spending six months recreating its backend.

docs: https://t.co/VyNTJwon9T

bookmark this. build something already.

[OpenDEX @opendex_ws]
