Solid keeps evolving, and this week we’ve added new features and refinements to make your experience even smoother, clearer, and more transparent.

Over the past two weeks, we’ve been doubling down on usability — from richer charts to easier deposits and smarter country handling. Every detail matters as we shape Solid into the most seamless way to save and grow your money.

What’s New in the App

• Coin Details Upgrade: When you open a coin’s details page, you’ll now see your balance front and center, plus a new historical coin chart to follow performance over time.

• Savings Insights: The SavingCard now shows your earning yield directly, and we’ve added a historical APY chart so you can track how your returns are building.

• Country Selection Made Simple: We’ve rolled out a new country selection screen with confirmation and processing states. If you’re in a waitlisted region, you’ll now get clear updates and even email notifications to stay in the loop.

• Deposits Made Easier: We’ve redesigned the deposit modal with a cleaner, more intuitive UI making it simpler to navigate, faster to use, and easier to connect your funds.

Under the Hood

• Transaction Types Expanded: We’ve added more detail to transaction types and how they’re displayed in your activity feed.

• Smarter Error Tracking: Sentry integration now captures unknown transaction types, helping us debug faster and improve your overall experience.

• Visual and UI Polish: Cleaner layouts in Activity details, skeleton loaders for wallet balances, and fresh updates to the soUSD logo and gradients.

Fixes and Polish

• Fixed issues with APY calculations in Savings.

• Corrected transaction values in the Activity feed.

• Resolved invalid time values and token send bugs.

• Removed the Coins tab on mobile to keep the app lean and focused on what matters most.

• General performance tweaks, code cleanup, and reliability fixes.

Stay tuned!

Finance should be simple. With the Solid Card, built in partnership with Bridge and Visa, you can finally earn automatically and spend instantly (on Fuse), and anywhere Visa is accepted.

Effortless by design

Open the Solid app, complete ID check, and your card is issued in minutes. Add it to Apple Pay or Google Pay and you’re ready to go. No waiting, no extra steps, just tap & pay.

Spend everywhere, earn as you go

Your money never sits idle. Solid puts your dollars to work in the background with institutional-grade yield strategies. While your balance grows, you can spend it at 200M+ Visa merchants worldwide, from Uber to Starbucks, Airbnb to your local café.

Every purchase will earn 2% cashback (in FUSE) powered by Solid, credited monthly and tracked in your app. A Premium tier is already on the roadmap, with up to 5% cashback and boosted rewards on popular subscriptions like Netflix, Spotify, and Prime.

Reserve your Card

Control and transparency

Solid is non-custodial: your funds stay in your wallet until you spend them. You decide how your card works, freeze or unfreeze instantly, set limits, and see every transaction in real time with no hidden charges. Read more in our docs.

Security you can trust

Your card is issued by Bridge, a PCI-compliant provider, with Visa’s global security standards baked in. And because Solid is non-custodial, your money never leaves your wallet until you spend it.

Launching Soon — Pre-Order Today

We’re starting with the Virtual Solid Card, available first in the US, LATAM, Africa. More countries and a Premium card with extra perks will follow.

While all of this is coming very soon, you don’t have to wait. The rollout is right around the corner, and early access is open today. Simply open the Solid app and pre-order your card to secure your spot. You’ll be first in line to receive it when it goes live and will get notified as soon as it’s ready.

Reserve your Card

This is a special one: it’s our first ever weekly update for Solid. Over the past months, we’ve been building hand-in-hand with our OG testers, listening closely, and improving the app step by step. Thanks to their feedback, we can now confidently say Solid is fully functional and ready for the public.

From here on, you can expect regular updates like this, giving you a transparent look at what we’ve shipped, what’s been improved, and what’s next.

And here’s a heads up: today’s update ends with a teaser you won’t want to miss. Trust us — you’re going to love it.

What’s New in the app

We’ve launched a brand-new Activity Details Page so you can explore your financial moves in more depth. Whether you want to zoom in on a single transaction or follow your flow over time, it’s now easier to see exactly what’s happening with your money.

You’ll also notice an APY display across the app. No more guessing Annual Percentage Yields are now right where you need them, making it easier to track how your balance is growing. And if you’re on mobile, the Overview page now feels smoother and more responsive, so your info is always at your fingertips.

Finally, we’ve given Deposits and Swaps a tune-up. Moving between assets or topping up is now faster and more reliable than before.

Under the hood

Some of the biggest wins this week are the little things you might not see right away:

• Activities are now grouped by time, so your history is easier to follow.

• Navigation feels snappier, thanks to improved routing.

• Loading states and referrals are cleaner, reducing friction across the flow.

Fixes and polish

We’ve tidied up chart overflow issues on mobile, trimmed unused code to lighten the app, and fixed a set of lint errors. The end result? A leaner, faster Solid that’s easier to trust day to day.

We’ve also updated some terminology for clarity: what used to be 7D APY is now called Effective Position APY, and “All-time yield” is now 30D APY. And since Ethereum now better reflects how we operate, it has replaced Fuse in our chain display.

Something huge is coming

And that’s just what we can share today. There’s more we’ve been working on behind the scenes that we’re keeping under wraps for now, because we don’t want to spoil the surprise.

What we can say is this: a first-of-its-kind product on Fuse is on the way, built in partnership with one of the world’s biggest names. As of October 2025, this company was in the 20 most valuable in the world and it even ranked #34 on Fortune’s Most Admired Companies list.

Stay tuned — this one is going to change the game.

In DeFi, security has too often meant “just audits.” At Solid, we believe true protection goes far beyond code reviews. In a high-stakes, fast-moving environment like DeFi, protocols must be built not just to pass a checklist, but to adapt, defend, and recover in real time.

That’s why Solid is designed from the ground up with multi-layered defenses, constant monitoring, and an emphasis on prevention.

Let’s take a closer look at how it works.

Real-Time Defense with Check Point

Solid will be one of the first DeFi apps to integrate with Check Point, a global cybersecurity leader trusted by most Fortune 500 companies and listed on NASDAQ. Check Point is known for protecting enterprises at scale, and now we are bringing those prevention capabilities into DeFi for the first time.

Think of Check Point as a DeFi-native firewall: it will continuously monitor activity across the chain and, in the future, will detect and stop suspicious behavior before damage can occur.

Unlike traditional tools, its scope will extend across transactions, vaults, bridges, and third-party contracts. The goal: to catch contagious events before they spread, preventing a single exploit from infecting an entire system.

With Check Point, Solid is adding an active, intelligent, prevention-first layer of protection on top of audits.

More Than Just Audits

Of course, Solid’s smart contracts are audited, but in today’s complex DeFi landscape, audits alone aren’t enough.

Security must be ongoing, operational, and adaptive. That’s why our approach includes:

• Bug bounty programs to incentivize continuous, external scrutiny

• Real-time vault monitoring to detect anomalies and track performance

• Third-party risk oversight, especially for integrated strategies via BoringVaults and other protocols
  
  

Solid Vaults are built on the ERC-4626 standard, giving users transparent ownership and making vaults easier to audit, upgrade, and recover.

We also prepare for the unpredictable, from malicious contract upgrades to systemic contagion, by continuously hardening our systems through industry-wide updates and resilient design choices.

Lessons from the Past: Surviving the Terra Collapse untouched

Solid isn’t our first DeFi product. Before this, the Fuse team launched FuseDollar, a diversified stablecoin backed by a basket of assets.

When Terra collapsed in 2022, it triggered a wave of liquidations. Many protocols exposed to UST were wiped out, but FuseDollar maintained its peg. Why? Because it rebalanced automatically, shifting away from failing assets and preserving stability through diversification.

That same approach later protected it during the BUSD deprecation.

These experiences shaped how we think about risk. It’s not only about isolated failures — it’s about defending against cascading events across the ecosystem. Solid carries forward those lessons: monitoring not just our own vaults, but the broader DeFi landscape, and diversifying yield sources by design.

Protecting Against 3rd-Party Risk

Most yield platforms integrate with external protocols, exposing users indirectly to partner risks.

At Solid, every external strategy will undergo continuous oversight. Vaults won’t just be audited once; they’ll be actively monitored, with smart alerts for abnormal behavior, underperformance, or exposure to higher-risk pools. We treat third-party integrations with the same scrutiny as internal systems.

A Philosophy of Resilience

Security in DeFi shouldn’t be about reacting to disasters. It should be about preventing them. Solid’s architecture is designed to:

• Detect threats before they hit users

• Reduce exposure through diversification

• Isolate risk to prevent contagion

• Respond and recover quickly if needed
  

We believe security is not a feature — it’s a foundation.

Solid is built to do more than earn yield. It’s built to protect it.

Explore Solid today and experience the difference a security-first approach makes.

Join Solid

We call Solid a savings super-app because it makes banking with stablecoins effortless. You can earn, spend, and trade with a foundation designed to feel as simple as traditional finance, but with the power of DeFi under the hood.

Smarter Yield, Less Effort

During the beta, we focused on one thing: making your money work harder without the usual complexity. Solid delivers institutional-grade yield on USDC with rates currently around 8% APY. The strategies rebalance automatically in the background, so you don’t need to stake, manage, or micromanage. Just deposit and start earning from your first dollar.

Early Bonus Yield

As one of our first users, you’ll also enjoy an exclusive early bonus: +3% APY for two months on deposits of $100 or more. That’s on top of Solid’s standard yield (8-15%), giving you an extra boost for being early. This limited-time offer is only available until November 1, 2025.

Built With Feedback

Our beta users played a crucial role in shaping Solid. Their feedback helped us refine the interface, streamline the flows, and ensure everything feels seamless. Today, you can deposit directly from a bank account, a credit card, or from most major EVM chains including Ethereum, without worrying about gas fees or bridges.

Security Without Friction

Your funds are protected by SAFE accounts, biometric login, and real-time monitoring via Checkpoint. No seed phrases, no hidden backdoors, just the kind of security you’d expect from a modern banking experience.

Gradual Onboarding & Early Rewards

To keep everything smooth, we’ll be opening access gradually. Waitlist members will be onboarded in weekly batches, and each user will get an email notification when it’s their turn. If you want to move up the line, it’s not too late, referring friends will boost your position on the waitlist.

And here’s a little teaser: we’re preparing to roll out the Solid Points Program. Every action you take inside Solid will earn you points, and more points will mean bigger rewards down the line. So being early, and being active, will pay off.

A Visa Card on the Way

And we have even bigger news: a Visa card connected to your Solid account is on the horizon. Soon you’ll be able to instantly spend your yield wherever Visa is accepted, turning passive earnings into everyday utility. This will mark the first step in making Solid your everyday crypto app.

Looking Ahead

Solid is built for both desktop and mobile, and we’re excited to share that a mobile version is already on the way. Soon, you’ll be able to track your yield, deposits, and spending from anywhere with the same frictionless experience.

Solid is more than a wallet. It’s the foundation for the next generation of finance fast, secure, and effortless. If you’re on the waitlist, your journey starts soon.

Unlocking next-gen DeFi experiences through vertical integration

When we set out to build Solid, we knew exactly what we wanted: seamless user experience, zero friction, and the kind of robust security usually reserved for institutions. Achieving this meant finding the right foundation, one scalable enough to support our ambitions, yet flexible enough to control every detail of the user journey. That foundation is Fuse.

Solid isn’t just another DeFi app. It’s built on six years of Fuse’s infrastructure development, an Ethereum Layer-2 ecosystem where we’ve carefully assembled core building blocks: wallets, relayers, APIs, a DEX, and more. Now, we’re vertically integrating these legos into one unified experience that delivers secure, fast, and gasless transactions.

Most DeFi platforms are patchworks of third-party protocols. This often results in high fees, complex interfaces, and frustrating user experiences. Fuse solves this by providing everything Solid needs under one roof:

• The chain (L2 with instant finality) & Ethereum L1

• The accounts (smart wallets, no seed phrase)

• The middleware (gasless relayers, subgraphs, APIs)

• Yield Engine & trading engine (Algebra ,Voltage ,Veda)

• The app infrastructure (explorers, notifications, and more)
  
  

This lets us deliver a seamless, gasless, multi-device experience that feels more like a fintech app than a DeFi protocol.

Account Abstraction Done Right

Solid simplifies every interaction through ERC-4337 account abstraction. There are no seed phrases, no bridges, and no signing fatigue.

This experience is made possible by several core technologies:
SAFE powers smart accounts, offering users the security of a multisig setup by default.
Turnkey enables biometric login and passkey-based access, delivering a secure, keyless, and intuitive onboarding experience.
Pimlico provides the underlying infrastructure that ties it all together. It supplies the paymaster that enables gasless transactions, the bundlers that ensure seamless on-chain execution, and full ERC-4337 support for smart, self-custodial accounts.

The result is a smooth, secure experience that feels more like using a modern fintech app than a traditional DeFi wallet. Everything just works without passwords, complexity, or friction.

Optimized for Yield and Stability

Fuse was built for real-world payments and business use cases. That means stability, uptime, and cost-efficiency were part of the DNA from day one.

For Solid, this gives us:

• Reliable performance for vault execution and monitoring

• Fast indexing of user activity and vault positions

• Wholesale gas pricing makes Fuse the ideal home for consumer apps like Solid, so fees stay low and more of the yield goes back to the user.

• Custom logic is baked into the vault layer thanks to full-stack access
  

Beyond Dollars: A Full Financial Suite

Solid’s vision is bigger than a simple yield vault. It’s designed to be your entire financial hub, enabling you to:

• Earn yield on a variety of assets (ETH, BTC, stocks, and more).

• Spend your yield directly with the Solid Card (coming soon).

• Swap, trade, and manage your portfolio without gas or bridges.

• Leverage assets through upcoming lending and collateralization features including support for non-crypto assets like Tesla, Gold, and other tokenized commodities.
  

With Fuse, these features seamlessly integrate into one app, creating an accessible and complete financial experience.

The Road Ahead

Solid is just getting started. Powered by Fuse’s scalable and flexible stack, we’re set to roll out features that blur the line between finance and everyday life:

• Support for more assets like Ethereum, Bitcoin, ETFs, and tokenized stocks (e.g., Tesla, Gold)

• Lending, borrowing, and advanced portfolio strategies

• Enhanced trading tools and seamless portfolio management

• A gamified experience with quests, points, and referrals built directly into the app
  

This isn’t just about removing friction, it’s about making finance feel intuitive and fun. Yield isn’t a feature, it’s the foundation. Solid turns passive income into a playful, rewarding journey that anyone can join.

Solid: built differently, thanks to Fuse.

Why We Built SOLID

DeFi promised financial freedom, but for most, it remains out of reach. There’s over $110B locked in DeFi, yet only a few million users engage actively, and the majority are developers, insiders, or institutional players. The problem isn’t the lack of yield. It’s access. DeFi is still too complex, too risky, and too technical for most people. On major Layer 1s, usage is dominated by whales and bots, not everyday users. The potential exists, but it’s buried behind convoluted interfaces and hidden risks leaving most people on the sidelines.

DeFi has evolved, now it’s time to combine the best of both worlds: a seamless, centralized-like experience with no middleman, no banks, and no borders. It’s finance without friction and better than a bank.

What is SOLID?

SOLID is more than just a wallet or a stablecoin. It’s the first non-custodial banking experience designed for everyone. Start with dollars, earn yield automatically, and unlock a gateway to explore Bitcoin, stocks, and DeFi, all without giving up control. Simple, safe, and built for the future of finance.

SOLID is a tool designed for anyone with a phone and an income. Our goal isn’t to teach your grandma how to use DeFi. It’s to remove the need for her to even know it’s there. SOLID hides the blockchain complexity and removes the bank from the equation, giving users direct access to yield with full transparency and zero friction.

This marks a paradigm shift. Until now, you either had a banking license or you built for devs and degens. With SOLID, we’re building for everyone else.

SOLID combines earning, spending, and saving in one seamless experience:

• Earn yield automatically when you deposit.

• Spend freely using your SOLID balance with an upcoming Mastercard & Visa card.

• Grow passively from battle-tested DeFi strategies that are curated for safety and return.

SOLID is built on battle-tested L1 and L2 infrastructure, powered by Fuse, and backed by trusted investors. It’s a fresh, consumer-first brand bringing DeFi to the mainstream. Gasless, cross-chain, and seamless by design, SOLID fades into the background while the benefits stay front and center.
