15.5

Release Notes - STRATO Release 15.5

December 30, 2025

---

Highlights

STRATO 15.5 brings an innovative breakthrough in DeFi trading with stableswap pools—a new pool type that dramatically reduces slippage for stablecoin and correlated asset swaps. This release also includes enhanced price visualization, personalized swap history, and expanded oracle sources for better reliability.

---

🔄 Stableswap Pools - Innovative Trading Technology

A Breakthrough in DeFi Swap Efficiency

STRATO 15.5 introduces an innovative stableswap algorithm—a specialized liquidity pool design that revolutionizes trading for stablecoins and correlated assets. Unlike traditional constant-product pools that work well for volatile pairs, stableswap pools use advanced math to maintain tight pricing curves for assets that should trade near parity.

Why This Innovation Matters

• Dramatically lower slippage - Trade 10x-100x larger amounts with minimal price impact compared to traditional pools
• Superior capital efficiency - Liquidity providers can earn more fees using less capital
• Precision pricing - Specialized curve algorithm keeps prices stable even during large trades
• Better user experience - Get the rates you expect without surprises

Innovation in Action

Two groundbreaking stableswap pools are now live:

• XAUtST-GOLDST - The first pool enabling efficient swaps between tokenized gold assets on STRATO
• sUSDSST-USDST - Ultra-low slippage trades between USDST and Sky Protocol's sUSDS savings token

Getting these assets: You can bridge in XAUt (Tether Gold) and sUSDS from Ethereum to receive the wrapped tokens XAUtST and sUSDSST on STRATO. Simply use the Deposit page to bring these assets over and start trading on the new stableswap pools.

This flexible architecture allows administrators to create new stableswap pools alongside traditional constant-product pools, ensuring every asset pair gets the optimal trading algorithm for its characteristics.

📊 Asset Price Charts

See Spot Prices and STRATO Prices Side-by-Side

Asset detail pages now include comprehensive price charts that show both external spot market prices and STRATO on-chain swap prices in a single view.

What You'll See

• Dual price comparison - Compare STRATO swap prices against global spot markets
• Historical data - Track price movements over time
• Visual clarity - Blue for spot prices, orange for STRATO prices
• Market insight - Understand price relationships and arbitrage opportunities

Navigate to any asset page to explore the new price visualization.

🔄 My Swaps Filter

Track Your Personal Swap History

You can now filter swap history to see only your own transactions, making it easier to track your trading activity without scrolling through the entire platform's swap history.

What's New

• My Swaps button - Toggle between viewing all swaps and just your personal transactions
• Personalized tracking - Quickly review your own swap history and performance
• Cleaner interface - Focus on what matters to you

---

📊 Enhanced Price Reliability

More Data Sources for Accurate Pricing

The oracle now pulls from additional price sources, ensuring more reliable and accurate asset pricing across the platform.

What Changed

• Additional token price sources - Expanded data providers for better price coverage
• sUSDS support - Added price feed support for Sky Protocol's sUSDS savings token
• XAUt oracle - New price feed for Tether Gold (XAUt), providing accurate precious metal pricing
• Improved reliability - More data sources mean better uptime and accuracy

These enhancements ensure you always have access to current, reliable pricing information for all supported assets.

---

🛠️ Fixes & Improvements

• Swap calculation accuracy - Improved swap input calculation logic for better precision in stable pools
• Oracle transaction reliability - Enhanced oracle transaction submission with improved polling mechanism

---

Release Notes - STRATO Release 15.4

December 23, 2025

---

Highlights

STRATO 15.4 brings a polished dark mode experience with improved branding, enhanced price reliability for precious metals, and clearer swap pool metrics.

---

🎨 Dark Mode Enhancements

Updated Visual Identity

We've refined the dark mode experience with optimized logo assets and improved theme consistency across the application.

What's New

• Optimized logos - Cleaner, smaller logo files for faster loading
• Better contrast - Improved readability in dark mode
• Theme persistence - Your theme preference now follows you through authentication flows

---

📊 Weekend Price Support for Precious Metals

Continuous Market Data for GOLDST and SILVST

Precious metals markets close on weekends, but your portfolio tracking doesn't have to. The oracle now maintains accurate pricing even when commodity markets are closed.

How It Works

• Alternative data sources - When spot markets close, the oracle switches to tokenized precious metals (PAXG for gold, KAG for silver) that trade 24/7
• Seamless experience - View your portfolio value any time without gaps
• Automatic switching - Prices revert to spot markets as soon as they reopen

This ensures you always have visibility into your GOLDST and SILVST holdings, regardless of commodity market hours.

---

🔄 Swap Pool Values Now in USD

See Your Pool Holdings in Dollars

Swap pools now display all liquidity values in USD instead of LP token amounts, making it much easier to understand the actual value of your positions at a glance.

What Changed

• TVL - Total Value Locked across the entire pool, shown in dollars
• Your Liquidity - Your specific holdings converted to USD value

No more mental math to figure out what your LP tokens are worth!

---

🛠️ Fixes & Improvements

• Rewards page refresh - Total earned rewards now update correctly after claiming
• Testnet indicator - When using testnet, you'll now see a clear "Testnet" label in the header
• One-click theme toggle - Simplified the dark/light mode switcher for faster theme changes
• Analytics support - Enhanced content security policy to support Google Analytics and LuckyOrange
• Dashboard refinements - Minor text and layout improvements across the platform

---

Notes

These updates focus on polish and usability improvements, making the platform more reliable and easier to use across different environments and market conditions.

---

🚀 Getting Started

Checking Metals Prices on Weekends

Your GOLDST and SILVST balances will now show accurate values even when precious metals markets are closed. Simply check your dashboard or portfolio page any time to see your current holdings valued at the most recent market prices.

15.3

Release Notes - STRATO Version 15.3

December 18, 2025

---

Highlights

This release improves the day-to-day STRATO experience with two new swap pools (ETHST-WBTCST and GOLDST-SILVST), smoother Rewards and Swap interactions, clearer portfolio insights, and better visibility into deposit progress plus continued UI polish across web and mobile.

---

🔄 New Swap Pools

We’re expanding swap options on STRATO—two new markets are now live:

• ETHST-WBTCST
• GOLDST-SILVST

Why You’ll Love This

• More ways to rebalance - Move between key assets directly, without routing through other pairs.
• Better flexibility - Choose the route that fits your strategy (portfolio shifts, hedging, or simply getting to the asset you want).

---

🎁 Rewards Experience Improvements

Rewards are now more consistent across the app, especially as new earning activities and pools get added over time. You’ll see cleaner labels, better leaderboard usability, and fewer “missing rewards” edge cases.

What You’ll Notice

• More reliable rewards detection - Rewards are matched using the underlying contract addresses (not hardcoded names), so new pools and activities show up correctly.
• Smoother rollout of newly rewarded pools - Backend indexing configuration was improved so additional rewarded pools can be enabled more reliably once they’re ready.
• Better mobile experience - The Rewards menu is now available on mobile (it was previously missing from the mobile sidebar), and the leaderboard table is easier to use on smaller screens.
• Seasonal competition - Rewards Points and your place on the leaderboard are tracked by season, so each season has its own standings.

---

🔄 Swap UX Fixes

Swapping is now more predictable and less error-prone during fast token changes.

What’s Improved

• Fewer swap “token flip” hiccups - Fixed a race condition when switching the “from” and “to” tokens quickly.
• Cleaner balance display - Removed a redundant balance indicator in the swap widget for a simpler, less confusing view.

---

🌉 Bridge & Deposit Progress

Deposits now provide clearer step-by-step feedback, so you can understand exactly where you are in the process (and what STRATO is doing in the background). You can also track deposits you’ve already initiated without leaving the Deposits page.

What’s New

• Step-by-step progress modal - When you deposit, you’ll see an in-app progress tracker that walks you through each stage:
  • Approve Token (for ERC‑20 deposits)
  • Sign Permit (when required by your wallet flow)
  • Confirm Transaction
  • Waiting for Transaction (on-chain confirmation)
  • Processing Deposit (STRATO finishes processing after confirmation)
  • (Easy Savings deposits also include a “Waiting for Autosave” step.)
• Safe to close when done - After the deposit reaches the final “Processing Deposit” stage, you can close the modal while STRATO completes the background processing.
• Deposit History on the same page - The Deposits page now includes a Deposit History panel so you can monitor deposits you’ve initiated (including pending ones) alongside the deposit form.

---

📊 Portfolio Chart Enhancements

Your portfolio chart now includes additional context to help you understand movement at a glance.

• Amount change indicator - The portfolio graph now shows the amount change alongside the chart (so you can see how much changed, not just the trend).

---

🛠️ STRATO API & Platform Improvements

This release improves the STRATO API and platform observability to support integrations and operational reliability.

• Transaction search by time window - The Transaction API now supports filtering results by a timestamp range.
• Higher per-request cap - Increased the maximum number of transactions returned in a single Transaction API request (capped at 100).
• More accurate timestamps - Transaction timestamps recorded in the database are aligned to the block time for more consistent reporting.
• Operational monitoring - Added transaction timing metrics to improve diagnostics and performance tracking.
• Better complex input handling - Improved parsing for contract call inputs that include JSON-like arrays/objects (helpful for advanced integrations).

---

🎨 UI Polish & Branding Updates

Small-but-noticeable improvements landed across the UI, plus refreshed logos in supporting STRATO apps.

• Dark theme UI refinements - Additional layout and visual improvements across key pages.
• Updated branding assets - New logo assets in the SMD UI menu bar.

---

🐛 Fixes & Improvements

• CDP flows - Balances now sync after CDP actions, and double-submit protection prevents accidental repeated actions.
• Docs updates - Improved and expanded documentation in the GitBook docs set.

---

Notes

• For integrators: the Transaction API supports mintimestamp / maxtimestamp, and request limit is capped at 100.

15.2

Release Notes - Version 15.2

December 11, 2025

---

Highlights

Version 15.2 marks a major evolution with the STRATO rebrand, visible rewards everywhere, and enterprise-grade bridge reliability. Experience the refreshed STRATO identity with new logos and dark mode, see your reward earnings in real-time on every page, and enjoy seamless cross-chain transactions with automatic failover protection.

---

🎁 Rewards Visible Everywhere

See Your Earnings on Every Page

The biggest change in 15.2: reward calculations now appear on every page where you can earn. No more guessing how your actions affect rewards - see the impact before you confirm any transaction.

What You'll See

Every activity page now shows a Compact Rewards Display with:

• Current earnings - "Earning Now: X pts/day" shows your current reward rate
• Projected impact - As you type amounts, see how your rewards will change
• Visual feedback - Green arrows for increases, red for decreases
• Percentage changes - Exact percentage impact on your earning rate

Where It Appears

Look for the gold rewards box on:

• Lending Pool - Deposit/withdraw USDST to earn interest
• Liquidity Pools - Add/remove liquidity from swap pools
• Borrow - Borrow USDST against collateral
• Swap - Exchange tokens
• CDP - Mint USDST with collateral
• Safety Module - Stake for protocol security

Example

🪙 Earning Now: 15.3 pts/day
↗️ After Deposit: 22.1 pts/day (+44.4% ↑)

Why This Matters

Before: You had to visit the Rewards page to understand your earnings. Rewards felt disconnected from your actions.

Now: Every decision shows its reward impact immediately. You can optimize deposits, swaps, and liquidity provision to maximize earnings.

---

🌉 Enhanced Bridge Reliability

Automatic Failover for Uninterrupted Cross-Chain Transactions

The bridge now routes through the STRATO backend with automatic fallback protection, ensuring your cross-chain transactions succeed even when external providers have issues.

How It Works

• Smart routing - Primary provider attempts transaction first, automatically switches to backup if needed
• Seamless failover - Switches happen instantly without user interruption
• Secure credentials - All API keys stay protected on the server
• Authentication required - Only logged-in users can make bridge calls

Benefits

• Reliable - Bridge stays operational even during provider outages
• Secure - No exposed credentials, authentication prevents abuse
• Monitored - Centralized logging helps detect and resolve issues quickly

Real-World Impact

If your primary RPC provider has an outage, the system automatically switches to the backup provider and you continue your transaction without interruption - no bridge downtime.

---

🎨 Refreshed STRATO Brand & Dark Mode

15.0.4

What's New in STRATO

Version 15.0.4 | November 26, 2025

TL;DR

✅ Fixed a critical issue with single-token liquidity deposits
✅ Improved accuracy of revenue statistics
✅ Enhanced swap pool data to always show current information

Action required: None! Just refresh your browser.

What Changed?

This update makes STRATO safer and more reliable. Here's what we fixed:

✨ The Fixes

Security Fix: Single-Token Liquidity Deposits

We fixed an important issue where depositing a single token into a swap pool could give you the wrong amount of LP tokens. You might have received less (or more) than your fair share.

Now it's fixed:

• Single-token deposits work correctly and safely
• You get exactly the right amount of LP tokens
• Fair for everyone providing liquidity

This makes it easier to provide liquidity since you don't need to have both tokens!

Stats Page Accuracy

The STRATO Stats page was showing incorrect revenue numbers. We've fixed the calculations so all the numbers you see are now accurate and reliable.

What's better:

• CDP revenue correctly calculated for each asset
• Swap pool fees now use real market prices
• You can trust the data to make informed decisions

Swap Pools Always Up-to-Date

If you left the swap page open in another tab, the data could become stale. Now when you return to the page, everything automatically refreshes so you're always looking at current information.

What's better:

• Automatic refresh when you return to the page
• Loading indicator shows when data is updating
• No more outdated pool balances or prices

Behind the Scenes

We also made several infrastructure improvements to make STRATO more reliable and secure:

• Improved deployment processes for faster updates
• Enhanced system monitoring and health checks

Thank You

Thanks to everyone who helps make STRATO better! Your feedback and trust mean everything to us.

Version 15.0.4 | Released November 26, 2025

• Detailed breakdown for each token (USDST, WBTCST, GOLDST, SILVST, PAXGST, ETHST)

CDP Statistics Tab:

• Total collateral value locked in all CDPs

---

⚠️ Price Impact Warnings on Swaps

What it does: Shows you how much your swap will move the pool price before you confirm
How it works:

• Low Impact (< 1%): Green text, safe to proceed
• Medium Impact (1-5%): Yellow text, slight price movement
• High Impact (≥ 5%): Red text with warning message

Why it matters:

• Protects you from accidentally making expensive trades in small pools
• Helps you understand why you might receive fewer tokens than expected
• Allows you to decide whether to split large trades into smaller amounts

What you'll see:

Price Impact: 7.23% (High)
⚠️ High price impact — you may receive fewer tokens than expected.

Example scenario:

• You want to swap $10,000 USDST for GOLDST in a pool with $50,000 liquidity
• Price impact: ~8% (High)
• Warning appears, suggesting you split into multiple smaller swaps or wait for more liquidity

---

⚡ Improvements

Improved Block Timestamp Accuracy

Technical improvement:

• Fixed an issue where block timestamps could become stale if there was a gap between when block building started and when transactions were processed
• The system now updates timestamps on every call to makeNewBlock, ensuring accuracy even during low transaction periods
• Added monitoring to detect and warn about timing gaps

Impact:

• All transaction times are now precise and reliable
• Better tracking of when your transactions actually happened
• Especially noticeable during periods when few transactions are being submitted

---

Improved Data Indexing Reliability and Performance

• Significant improvements to blockchain data indexing that enhance reliability

---

Faster Loading Times

What we optimized:

• CDP asset lists now use parallel queries instead of sequential requests (significantly faster)
• Admin screens load and respond faster with improved state management

Impact:

• CDP collateral asset page loads ~3x faster
• Admin panel is more responsive when managing multiple assets
• Less waiting, more trading

---

More Frequent Price Updates

• Oracle price feeds update every 8 minutes (previously 15 minutes)
• More accurate pricing for your trades

---

Clearer information when withdrawing liquidity from swap pools

What was broken: After withdrawing liquidity, the withdraw modal and success message didn't clearly show what tokens you received or your remaining position
What we fixed:

• Success messages now show exactly what you received (e.g., "0.000123 WBTCST position" and "1,234.56 USDST position")
• The withdrawal modal displays your token positions more accurately
• Better token label extraction for pools

Impact: You can now clearly see your individual token positions after withdrawal, making it easier to track your liquidity

---

Security & Safety

Enhanced Asset Control System

What changed:

• Admins can now disable individual CDP collateral assets through the Admin UI
• Admin UI shows which assets are enabled/disabled with clear visual indicators
• UI now prevents users from opening new CDP positions with disabled assets

What this means for you:

• Safer platform overall - risky assets can be quickly disabled during market volatility
• Faster response to market issues or security concerns
• If an asset is disabled, you'll see a clear message
• Important: You can always close existing positions, even if the asset is disabled for new positions
• Transparent asset status - you'll always know which assets are available

---

Bug Fixes

Fixed Safety Module APR calculations

What was broken: The Safety Module exchange rate was showing APR based on raw token balance
What we fixed:

• Backend now uses the contract state variable instead of raw token balance
• This correctly accounts for funds that are managed by the Safety Module vs. orphaned deposits
• Exchange rate calculation now matches the actual assets under management

Impact:

• Safety Module APR and exchange rate now display correctly
• Users can accurately see their sUSDST token value
• Prevents confusion about Safety Module returns

---

Fixed Safety Module accounting for reserve sweeps

What was broken: When Lending Pool swept reserves to the Safety Module, the funds weren't properly tracked in the Safety Module's internal accounting
What we fixed:

• Added recordTransfer() function to properly account for incoming reserve sweeps
• Updated RewardNotified event to include the sender for better tracking
• Added balance delta verification to handle fee-on-transfer tokens
• Fixed coverShortfall() to use state-calculated amounts with verification

Impact:

• Reserve sweeps now correctly increase Safety Module TVL
• Stakers' exchange rate properly reflects protocol revenue
• More accurate APR calculations
