Real Use Cases Made Possible by Private Solidity Privacy unlocks an entirely new category of onchain applications. Things that are impossible on public blockchains become trivial on Seismic. Here are 5 real use cases you can build today all in standard solidity. Private Tokens (SRC20) : ERC20 where balances and transfer amounts are hidden from every observer. Users check their own balance through signed reads. No one else can see it. The only code change : uint256 → suint256. Observers see 0x00...0 across every balance and every transfer amount, identical logic, completely private state. Confidential DeFi AMMs where reserves, liquidity positions, and swap amounts are all shielded. The pool runs a standard constant product formula internally but because reserves are stored as suint256, no one outside the TEE can compute price impact on a pending swap. Front running and sandwich attacks become far harder when bots can't read pool state or pending swaps. Compliant Finance (Intelligence Contracts) shielded contracts with built-in access control for specific authorized parties. Balances stay private from the public. The COMPLIANCE_ROLE can call getBalance() and read the underlying value. Everyone else gets rejected, full financial privacy and regulatory access in the same contract this is the pattern institutions have been waiting for private voting secret ballot governance onchain. During voting, individual votes (hasVoted) and running tallies (yesVotes, noVotes) are all stored as shielded types. No one can see how a vote is trending mid period. When votingEnd passes, getResults() casts the tallies public and the outcome is readable but individual votes stay private permanently. Sealed Bid Auctions Every bid stored as suint256, highest bidder's address stored as saddress. No bidder can see what others have placed. Bid sniping and strategic underbidding are eliminated by design. When the auction closes, getWinner() reveals the result until then, not even the contract exposes who's leading. Five use cases. All standard Solidity. All running on a fully EVM compatible chain. The only difference from what you already build : the variables that should stay private now actually do.

🚨 **THE ONE THING A GLOBAL EXCHANGE SEES THAT CRYPTO DOESN’T AND WHY THEY’RE MOVING NOW** 🧵👇 Crypto thinks that a global exchange partnering with $Devve is about RWAs. It isn’t. It’s about owning the future of global markets. Most people in crypto think in days. A global exchange thinks in YEARS. Let me show you what they see, and what 99% of CT is missing. ⭐ 1️⃣ PHASE 1 — THE “BORING” START… THAT PRINTS MONEY 💰 People ask: “Will Phase 1 just be BTC, ETH and a few regulated assets? That’s it??” In all likelihood, yes. And that’s EXACTLY why a global exchange wants in early. Phase 1 is: - Safe - Regulated - Conservative - Institution-ready - API-driven - No smart contracts - No failures - No blowups Actual real revenue from Day One Revenue unlocked IMMEDIATELY: 💵 Spot fees 💵 Custody fees 💵 Fraud-protection fees 💵 Settlement fees 💵 Institutional onboarding Conservative estimate? $50M–$150M annual revenue from Phase 1 alone for a major exchange. No hype. No magic. Just business. 🚀 2️⃣ PHASE 2 — THE FIRST TRULY NEW PRODUCTS EVER OFFERED BY AN EXCHANGE ⚡️🌐 This is where it becomes obvious why the partnership happened. When liquidity, licensing and shards expand, $Devve enables products that cannot exist today. 🔷 Example: Instant Cross-Asset Swaps (Day 1 of Phase 2) $BTC → T-Bill T-Bill → $ETH Equity → crypto Bond → cash Crypto → sovereign bonds All in: ONE transaction UNDER a second ZERO counterparty risk ACROSS jurisdictions Over simple APIs Estimated revenue for the exchange: Cross-asset fees = new multi-hundred-million-dollar revenue category (Traditional systems cannot touch this. Zero competition.) This is the “Oh… now I get it” moment. 🌍 3️⃣ PHASE 3 — PRODUCTS THAT DON’T EXIST (YET). A TRILLION-DOLLAR ERA 🏦💥 This is the real reason a global exchange got involved. These aren’t tokenised versions of old products. These are new markets entirely. 🔶 Example: Atomic Global Repo Market A $12 TRILLION PER DAY market today. $Devve enables: $100M tokenised T-Bill (US shard) $98M tokenised cash (EU shard) Atomic repo in 0.5 seconds No clearinghouse No fails No intermediaries No settlement window No risk Revenue potential? Clearinghouses and intermediaries take $5B–$15B annually today. A global exchange running atomic repo rails? It could eat 30–50% of that. That’s billions per year. Not millions. Billions. And this is just ONE product category. Other Phase 3 examples: 🔹 Cross-jurisdiction lending 🔹 Atomic FX crypto baskets 🔹 Instant multi-asset rebalancing 🔹 Real-time structured notes 🔹 Multi-leg derivatives with zero risk 🔹 Products that literally DO NOT EXIST today This is why the partner signed early. Not for RWAs. But for the markets of the 2030s. ⚡️ HERE’S THE PART EVERYONE IS MISSING Many $Devve investors are still asking: “Will the Q4 milestons be hit?” “Will they reveal the partner this week?” They're thinking in days. Global exchanges think in decades. They don’t care about hype cycles. They don’t care about CT’s attention span. They don’t care about quarterly noise. They care about: - New markets - New fees - New rails - Global liquidity - Regulatory clarity - Atomic settlement - Owning the infrastructure layer - Multi-asset, multi-jurisdiction control - BILLION-dollar revenue streams This partnership isn’t about delivering one quarter. It’s about delivering the next financial system. 🧨 FINAL MESSAGE FOR INVESTORS If you’re sweating over the next few weeks, you’re missing the entire point. The market partner is not building for Q4. They’re building for the next 20 years. Phase 1: The foundation Phase 2: The shift Phase 3: The takeover Stop thinking like a short-term trader. Start thinking like the institution that just bet its future on this. This thing is MUCH bigger than your timeline. 📌 If they execute even half of this, it becomes one of the most important rails in global finance. @DevveEcosystem @DevvExchange

Ever imagined a dao where votes are secret but verifiable? Meet private poll, powered by @zama_fhe, democracy, encrypted. // SPDX-License-Identifier: BSD-3-Clause-Clear pragma solidity ^0.8.24; import { FHE, euint8, externalEuint8 } from "@fhevm/solidity/lib/FHE.sol"; import { SepoliaConfig } from "@fhevm/solidity/config/ZamaConfig.sol"; contract PrivatePoll is SepoliaConfig { mapping(address => euint8) private _votes; euint8 private _yes; euint8 private _no; function vote(externalEuint8 encryptedVote, bytes calldata proof) external { euint8 voteValue = FHE.fromExternal(encryptedVote, proof); _votes[msg.sender] = voteValue; // If vote == 1 → yes; else → no ebool isYes = FHE.eq(voteValue, FHE.asEuint8(1)); _yes = FHE.add(_yes, FHE.select(isYes, FHE.asEuint8(1), FHE.asEuint8(0))); _no = FHE.add(_no, FHE.select(isYes, FHE.asEuint8(0), FHE.asEuint8(1))); FHE.allowThis(_yes); FHE.allowThis(_no); } function getResults() public view returns (euint8, euint8) { return (_yes, _no); } } - Every vote is encrypted. - The logic runs privately, transparently. - No leaks, no hashes, no bias. Zama FHEVM just turned governance into cryptographic art.

Solidity & Secrecy: Writing Your First Encrypted Smart Contract with Zama If you’ve ever built on Ethereum, you know one thing: everything is public. Every transaction, every variable, every contract, it’s all out there for anyone to see. Transparency is the beauty of blockchain, but it’s also its biggest limitation. Now imagine writing a smart contract that behaves exactly like an Ethereum one, same Solidity code, same tools, but everything happening inside it is encrypted. Even the node executing it can’t see what’s going on. Welcome to Zama’s FHEVM, where Solidity meets secrecy. What Is FHEVM? Zama’s Fully Homomorphic Encryption Virtual Machine (FHEVM) is Ethereum with privacy armor. It lets you encrypt data and still perform computations on that encrypted data, without ever decrypting it. That means smart contracts can: • Take in encrypted inputs • Process them as if they were normal • Output encrypted results All while keeping the data completely hidden on-chain Why It Matters Ethereum’s transparency comes at a cost "Privacy". Developers building financial dApps, voting systems, or games face a tough tradeoff: go public or move sensitive parts off-chain. Zama’s FHEVM ends that dilemma. You can now write decentralized apps that are confidential by default. Imagine: • A DeFi app that approves loans without exposing credit scores • A voting system with hidden ballots • A game where player strategies stay private All directly on-chain. Solidity, but Private Here’s the beauty of it, if you know Solidity, you’re halfway there. Zama designed FHEVM to feel familiar. You still use Remix, Hardhat, or Foundry, but with Zama’s FHE Solidity Library to handle encrypted data types. Instead of uint256, you use euint256. Instead of , you use FHE.add(). It’s Solidity, 'just encrypted' Writing Your First Encrypted Contract Let’s build a simple private voting system: // SPDX-License-Identifier: MIT pragma solidity ^0.8.20; import "fhevm/lib/FHE.sol"; contract PrivateVote { euint256 private yesVotes; euint256 private noVotes; function vote(bool choice, euint256 encryptedWeight) public { if (choice) { yesVotes = FHE.add(yesVotes, encryptedWeight); } else { noVotes = FHE.add(noVotes, encryptedWeight); } } function getResults() public view returns (euint256, euint256) { return (yesVotes, noVotes); } } Each vote is encrypted before it hits the blockchain. Validators process it without knowing who voted or how they voted. The results stay encrypted until decrypted by the right keyholder. Transparent logic. Private data. How It Works Under the Hood Zama’s FHEVM integrates Fully Homomorphic Encryption directly into the EVM. Your encrypted variables stay locked throughout computation, math happens in ciphertext, not plaintext. The system ensures: • Data never leaks • Nodes can compute without decrypting • Only authorized keys reveal results And it’s still EVM-compatible, deployable with your favorite Ethereum tools. What You Can Build Privacy unlocks new frontiers in blockchain: • Private DeFi — Trade or stake without exposing balances • Confidential identity — Prove eligibility without revealing your wallet • Encrypted AI logic — Run private ML models on-chain Zama’s FHEVM isn’t just about hiding, it’s about enabling new use cases the blockchain could never support before. Getting Started @zama_fhe offers an FHEVM SDK and templates so you can start experimenting instantly. Clone their GitHub repo, use the fhevm-hardhat-template, and start coding your first encrypted contract in minutes. Privacy is now programmable. Solidity unlocked decentralized logic. Zama’s FHEVM unlocks decentralized secrecy. It’s the missing piece that lets you choose transparency where it matters, and privacy where it’s vital. Next time someone says “blockchain can’t be private,” tell them: “Mine is. It’s encrypted with @zama_fhe.”
