Introducing "Aruvi" where privacy flows freely - payment gatway for confidential tokens(ERC7984) "Integrate Aruvi gateway on any website to accept confidential tokens" - Built on top of @zama's fhEVM and @OpenZeppelin support - Wrap/Shield @circle Official $USDC on Aruvi ( currently on sepolia ) to use it as payment - Designed to handle ERC7984 send, request, subscription and refund > P2P for encrypted payments > Request for Request money with shareable links/QR codes > Multi-Send for Batch payments to up to 10 recipients > Subscriptions for Recurring payments with encrypted amounts > Refunds for Recipients can refund payments - like paypal/stripe but for privacy Live @ aruvi-dapp.vercel.app/ aruvi/sdk @ npmjs.com/package/@aruvi/sdk Repo @ github.com/ramakrishnanhulk2… Took me months but finally happy to introduce it, still some functions in contracts are yet to be implemented on frontend. Feedbacks are really appreciated.🫡 @randhindi

Zashapon: Digital theme park for Zama Protocol <Turn FHE usage into games, rewards, and status> @zashapon is a digital theme park where you earn tickets by using confidential apps on @zama, then spend them on gashapon machines for NFT rewards. It's the gamification layer that makes FHE adoption fun instead of technical. Live on testnet now. The insight: users don't adopt protocols, they adopt experiences. Zashapon makes FHE participation feel like entertainment, not work. The flywheel: use confidential apps → earn tickets → play gashapon → get rewards → flex/trade → invite friends → repeat -----------> How It Works Use confidential apps: make FHE transactions on apps like confidentialtoken.com Earn tickets: every transaction gives you tickets for participation Spend in Zashapon: use tickets on gashapon machines (digital vending machines) Get rewards: win NFTs, then later: whitelists, perks, access, real-world benefits Collect and flex: build your collection, trade with others, show status -----------> Physical theme parks: ride → collect → show → return with friends Zashapon: use confidential apps → earn tickets → draw → flex/trade → return with crew Launching with confidentialtoken.com machine, expanding to every Zama app Live on Zama testnet: zashapon.com This is how you make privacy tech adoption feel like entertainment, not homework 🎰 Users come for the gashapon, stay for the confidential computing #ZamaCreatorProgram

HCU: Zama's gas meter for encrypted computation <Privacy costs computing power, HCU tracks the bill> TLDR: HCU (Homomorphic Complexity Units) is like gas fees but for encrypted math on @zama. Simple encrypted addition costs 84,000 HCU complex multiplication costs 696,000 HCU. Transaction limit: 20 million HCU, or it reverts.​ Let me explain: Think of HCU like electricity bills: running your air conditioner costs more than a lightbulb, right? Encrypted math is expensive: adding two private numbers takes way more computing power than adding regular numbers​ HCU measures the cost: simple operations like addition = 84,000 HCU, complex ones like multiplication = 696,000 HCU​ Transaction has a limit: 20 million HCU per transaction or it fails​ Why it exists: prevents people from crashing the network with infinite encrypted calculations​ -----------> The Cost Breakdown Cheap operations (under 100k HCU): Addition/subtraction on encrypted numbers: 84k-172k HCU​ Bitwise operations (and/or/xor): 30k-39k HCU​ Equality checks: 55k-118k HCU​ Expensive operations (over 500k HCU): Multiplication on 64-bit encrypted numbers: 365k-596k HCU​ Division: 715k HCU​ Remainder: 1.15 million HCU​ 128-bit multiplication: up to 1.7 million HCU​ Bigger numbers = more cost: 8-bit addition costs 84k HCU, 128-bit addition costs 172k HCU​ -----------> Why This Matters? Privacy isn't free: keeping data encrypted while computing costs real hardware resources​ Developers must optimize: can't just spam encrypted operations, need to design efficiently​ HCU limit forces choices: either refactor code to use fewer operations or split across multiple transactions​ Different from normal gas: regular Ethereum operations cost pennies, FHE operations cost way more because hardware is crunching encrypted data​ Trade-off for privacy: you pay higher computational cost to keep everything encrypted end-to-end​ -----------> Real World Analogy Normal blockchain: like doing math on a whiteboard (everyone sees, super fast, super cheap) Zama with HCU: like doing math inside a locked safe without opening it (private, slower, more expensive)​ HCU is the safe-cracking cost: simple operations crack easier (lower HCU), complex operations need more work (higher HCU)​ 20 million HCU limit: you can only crack so many safes per transaction before network says "stop"​ It's the price of end-to-end encryption on public blockchains #ZamaCreatorProgram

OpenZeppelin x @zama Confidential Contracts v0.3.0 shipped <Production-ready FHE extensions for private smart contracts> @OpenZeppelin just dropped v0.3.0 of Confidential Contracts library with FHEVM 0.9.1 upgrade + ERC-165 + new extensions for real-world assets, access control, and freezable tokens Major upgrade: @fhevm/solidity 0.9.1 brings latest Zama TFHE optimizations and User Decryption patterns Why this matters: developers get battle-tested OpenZeppelin security patterns but for encrypted data onchain -----------> What's New ? FHEVM 0.9.1 integration: latest Zama FHE library with improved performance and ACL patterns ERC-165 support: standard interface detection works with confidential contracts now Omnibus extension: batch operations on encrypted data for gas efficiency Observer Access: granular permissions for who can view encrypted state Restricted extension: programmable transfer restrictions on confidential tokens Freezable: pause/unpause functionality that works on encrypted balances RWA ready: real-world asset tokenization with privacy built in -----------> Use Cases Unlocked Private stablecoins: encrypted balances with freezable/restricted transfers for compliance Confidential RWAs: tokenize real assets with privacy-preserving ownership Private DAOs: voting and treasury with encrypted proposals and balances DeFi with privacy: confidential swaps, lending, derivatives using standard interfaces Enterprise onchain: businesses can finally use public chains with private data -----------> The Bottom Line: OpenZeppelin bringing institutional-grade security patterns to Zama FHE v0.3.0 = developers can build confidential apps with familiar OZ tooling RWA, access control, freezable extensions = real use cases not just demos GitHub: github.com/OpenZeppelin/open… #ZamaCreatorProgram
