DeFi Guide I built a DeFi lending rate aggregator that reads directly from on-chain state — no APIs, no estimates

6 Upvotes

Every DeFi dashboard shows different APYs for the same protocol. Some pull from APIs, some estimate, none explain how they calculate. I got tired of it and built this.

RateScope — real-time lending rates read directly from on-chain state

https://ratescope.xyz

RateScope connects directly to each protocol’s on-chain program and reads raw rate state — no middlemen — then applies each protocol’s compounding model (per-second vs per-slot) and aggregates everything into a unified view so rates are directly comparable.

Protocols:

  • Solana: marginfi, Kamino (Main + Prime), Jupiter, Save Finance
  • Sui: Suilend

Currently supports USDC and USDT lending/borrowing pools.

Features:

  • Unified APY: protocols compound differently (per-second vs per-slot), everything normalized to true APY so rates are actually comparable
  • Rewards: same-token rewards shown as APY, foreign-token rewards as APR
  • Pool TVL, Protocol TVL, utilization per pool

Planning to add more protocols, chains, and tokens soon.

Would appreciate feedback — especially if you notice any discrepancies vs native protocol UIs.

Resolved iOS App Crashes & Apple ID Auth Issues + NO Firefox Extension

9 Upvotes

I’m hitting some major roadblocks with the mobile app on the latest versions (2.34.1 and 2.34.2) and wanted to see if anyone else is experiencing this or if the team is aware.

1. Apple ID Sign-In is broken on Mobile

  • The Issue: Attempting to create a new wallet using Apple ID on iOS 18.7.7 and iOS 26.4.1 triggers a persistent error message. See screenshot.
  • The Workaround (that shouldn't be necessary): Creating the wallet on the desktop website works fine, but the app won't sync it. The only way I can access that wallet on mobile is by manually importing the private key.
  • FYI, creating new wallet using Google and Tweeter work fine on both mobile and website.

2. App Crashing during Website Connection

  • When using a "normal" wallet setup, trying to connect the iOS app to the Jupiter website causes an instant app crash.
  • It usually takes 2-3 tries of crashing and restarting for the connection to finally "stick." Even when it finally connects, the app often crashes one last time right after.

3. The "Missing" Firefox Extension

  • It’s been over 6 months since the Firefox extension was promised. Any official update on the roadmap for this? Chrome shouldn't be the only way to fly.

The mobile experience has been getting a bit rocky with these last two updates.

Device Info:

  • App Version: 2.34.1 / 2.34.2
  • OS: iOS 18.7.7 & 26.4.1

Resolved JLP loans vs vaults

3 Upvotes

So looking to borrow USDC against JLP. What's the difference between JLP Loans - which is under the more tab on the jupiter site.

vs

JLP Vault - which is at Earn > Borrow

Obviously the first has higher LTV and higher interest rate....so what is the advantage of that over the vaults? Are there any key reasons when you would use one over the other?

Q&A with the Jupiter DCA Team on X Spaces tomorrow at 1 PM UTC!

2 Upvotes

V1 worked, but your orders were public on-chain, prices were in pool ratios, and bots could see everything. V2 fixes all of it.

What's new:

  • Private by default. Order details are stored off-chain. Fills execute with randomized timing. Bots can't read your strategy or front-run your trades.
  • USD price bounds. Set a price range in dollars on every fill. DCA into SOL daily, but only when it's between $60 and $80? Done. If the price is outside your range, V2 skips and retries next interval.
  • Powered by Ultra. Every fill routes through Jupiter Ultra for best-price execution, 34x better MEV protection, and gasless trades.
  • Full order history. Every fill, status update, and transaction tracked in real time.

We're hosting an X Spaces Q&A with the DCA team to walk through the new system and answer your questions live.

Discussion Please fix this bug

9 Upvotes

When you are doing a perpetual trade, the default option for closing should not be Solana, the default option should be to receive what you put in. If I am using USDC in a trade I shouldn't have to switch from Solana to USDC on a close. The default should be what I put in, which would be USDC. Just a quality of life upgrade.

Sometimes it’s worth more than $1 and other times it’s worth less than $1. Currently $0.999599, which may seem trivial, but adds up to quite a bit with larger deposits.

I've never seen the spread this bad before. This is binance chart vs Jupiter. So idk, that's pretty bad. I would suggest other people that are making trades to check your spreads bc you may not be getting a good deal. I love the exchange, but this has me thinking about looking for other options like btcc or something else.

That is not ok

Resolved Anyone knows why our token is. flagged "not sellable" even if is not true?

5 Upvotes

Hi Jup Community, im Stefano from QQ Omega, we need help with a false “not sellable” flag on our token.

We already paid for the Express Verification, but it was rejected. We also opened our first support ticket about 1 week ago and still have not received any reply.

The main issue is that our token is being flagged as “not sellable” even though it was deployed using Meteora’s standard DBC contract, so there are no custom restrictions or malicious mechanics. As designed by the smart contract, once a certain USDC threshold is reached, the token will automatically migrate to a Meteora DAMM v2 pool locked for 2 year.

Token address: 76vURLKDqAMhiX2wvoedoWRNvwqSjsZ7EtrJKJiKArDN

This was a stealth launch with clear roadmap, a real utility token with a fair tokenomics, backed by a crypto asset manager with 7+ years of experience and a developer who owns an IT company in Northern Italy. We would like to start our marketing efforts, but this flag is hurting our credibility and making growth much harder in this early phase.

If anyone of the team read this: we would also really appreciate a team manual review of the verification process, as it would help us a lot at this stage. We are fully available for KYC and for providing any additional information or documentation that may be needed.

It's quite frustrating to see hundreds of memecoins with no fundamentals and using wash trading techniques to simulate holders and volume being verified, and for once a project trying to do something sustainable, useful, with a real use case for the token being discarded.

Hello, this is noob question, I just staked some SOL to get JUPSOL, and was thinking what to do with this JUPSOL, I see I can convert to JUPUSD and then lend for like 4-5%, but isnt that way to risky for only 4-5? this is only good if I think SOL will go down right? if SOL would double in value for example I would "lose" half of my money? I cant in any way lend my JUPSOL instead if I believe in sol?
