After 16 weeks of RIGOROUS grind at @Web3Bridge, participating in their Zero Knowledge program; My team built a full shielded token stack on EVM for private token transfers and I’m sharing both a demo video (Privacy native wallet extension User facing dApp UX) and the technical paper in this post. Architecture: Noir circuit Barretenberg/Aztec UltraHonk proving Solidity verifier relayer client-side note discovery. Model: UTXO-style notes with - commitment = Poseidon(owner_pk, token_field, amount, blinding), - Nullifier-based one-time spends (nullifier = Poseidon(spending_key, commitment)), - Depth-20 incremental Merkle tree rolling root window, fixed public input lanes, and mode-gated constraints for transfer/unshield. - ShieldedERC20Pool (multi-token allowlisted pool) with routed encrypted note delivery (RoutedCommitment) using ECDH HKDF-SHA256 AES-GCM, and channel/subchannel for note discovery. Design goal is explicit: private in-pool state transitions with verifiable integrity, while shield/unshield remain honest public boundary actions. If you watch the video read the paper, you’ll see both the privacy native wallet extension and the user facing dapp full loop working end-to-end: shield → private transfer(s) → note scan/decrypt → nullifier checks → unshield. Big shout out to the mentors holding our hands throughout the duration of the program. The knowledge passed has been invaluable. @WiseMrMusa, @only1franchesco, @Oba_Ddev, @Dev_esayayo. Next steps for us are; - Production hardening and compliance-by-design - Formal security review/audit of circuits/contracts/relayer, wallet key-management hardening (secure enclaves/HSM-backed options), relayer auth anti-replay protections - Performance tuning for proof latency/UX. - In parallel, we’ll implement a compliance layer that preserves base protocol privacy while enabling jurisdiction-aware controls at the app edge (sanctions/geo screening for boundary actions, risk scoring/transaction monitoring, optional disclosure and auditable consent flows for regulated contexts), alongside legal review and phased rollout with testnet pilots before mainnet.

Cool!!!!!! Shielded mode on

1k downloads is a checkpoint, not a finish line. We've been heads down; shipping, fixing, listening. Every piece of feedback made the tool sharper. The roadmap is moving and the best updates are still ahead. @StacksDevs

On-chain privacy shouldn't mean compromising on speed or liquidity. Tomorrow, June 9th, the strk[20] standard goes fully live on mainnet, bringing native, compliant privacy to every ERC20 token on @Starknet The global ecosystem is ready. Are you? #Privacy #DeFi @StarkWareLtd @windrider0227 @tsubasaP2E @Nacto1122 @kenzman18 @Nadai02010 @StarknetFndn @StarknetEspreso

Secure your spot! Expand your skill set. Solidity alone in 2026 won’t cut it. The Zk track @Web3Bridge closes in 2 weeks, this is your time to stay ahead anon.

Bitcoin was built for public verification, not public exposure. On this episode of @StarknetEspreso, we sit down with @thenewgold_btc from @xverse to explore how the @Starknet / Xverse partnership is transforming Bitcoin. We dive deep into the launch of strkBTC, moving $BTC beyond just a store of value into a private, productive asset for yields [strkBTC]. Plus Xverse's native, in-wallet DeFi plays on starknet and bridging architecture. Watch full podcast 👇 $strkBTC #starknet #bitcoin @StarkWareLtd

Turning Bitcoin into a private, yield-bearing asset on @Starknet is not a roadmap; it's already live! @thenewgold_btc from @xverse breaks down the opportunities for strkBTC holders in this clip from the latest episode of @StarknetEspreso Full Episode👇 x.com/uche2v/status/20613495…

Off-ramping in Nigeria shouldn't be a headache. 💸 @ResolvaHQ and @atomiqlabs are changing the game for seamless, secure off-ramps If you're building or moving liquidity in Web3, here's my best gift for you this year. 👇 @Starknet #Starknet #BTCFi #CryptoNigeria #Web3‌‌ @codingcas

If you haven't updated Xverse to v2.4, you're still running public Bitcoin. Mobile [shielding] is live. Shield your @Starknet strkBTC from your phone 📱 A private balance. Private transfers. Unshield anytime. Update / download now to enjoy the magic: xverse.app/download

Everything you do onchain is permanently visible. Until now. Earlier this month, we introduced strkBTC: Private Bitcoin on Starknet. In June, that model expands beyond BTC. STRK20 is the next step 🧵

The era of dormant, exposed Bitcoin is officially over. The launch of strkBTC on @Starknet introduces programmable $BTC with zero-knowledge, asset-level privacy. Deep-dived with the co-founders of @atomiqlabs, @Sylvie0301 & @AdamBorco, and the founder of @just_brove_it, @Nadai02010, to explore the biggest upgrade to Bitcoin's utility and the opportunities it brings to both retail users and institutions. @StarkWareLtd #BitcoinTrend #defi #Blockchain #Web3‌‌ #crypto #ERC20 Full Episode here👇🏾

First look at a Cross-chain USDC invoicing. Send a pay link. Clients pay from any chain. One balance on @arc. Built on Circle CCTP.. Watch demo here.

Here's how you get and shield your $strkBTC on @xverse. @starknet gives you safety, sovereignty, and privacy with strk20. @StarkWareLtd

Watch how to go from contract to full-blown dapp in under 4 minutes using the stacksdapp CLI. In the demo we build an on-chain message board: users connect a wallet, post messages stored on @Stacks, and pay a tiny sBTC fee (1 sat) per message. Clarity contract, reusable hooks, and a Next.js debug UI, all wired up end to end. Scaffold Stacks bridges the gap between Clarity smart contracts and modern frontends. It lets you focus on logic while we handle the infrastructure. docs: scaffoldstacks.mintlify.app/ @StacksDevs @StacksOrg @stackslabs @hirosystems @muneeb @katemparkman @ECBSJ @StacksEndowment

Your stacksdapp CLI update - Full-stack Stacks dApps from one CLI. stacksdapp v0.1.8 is out - `stacksdapp test ` now runs contract frontend Vitest (not just contracts)
 - Next.js build fix: read-only codegen works with @stacks/transactions v7 (getReadOnlyNetwork, no broken fetchOptions)
 - @stacks/network v7 in the template Hiro API key support
 - Wallet cleanup: removed dead useWallet context; Jotai  WalletProvider only

ZK delivers scale, and ZK delivers privacy, and it does both by relying on a proof. This moon-math proof is key to everything: It attests to the validity of txs, and verifying the proof alone is enough to know that you can update the state based on these txs without having to re-execute them (that's how we get scale), and without having to see their details (that's how we get privacy). If you want a simplified (but long!) explanation about HOW do you build such a moon-math proof, this article is for you. Enjoy ;-)

Bitcoin is the most sovereign money ever created. It is also the least private money people have ever used. strkBTC fixes that. Live on Starknet today. 🧵

Shielded token system on EVM using Noir UltraHonk where value lives as private UTXO-style notes (commitments in a Merkle tree), spends are authorized by ZK proofs, and double-spends are blocked by onchain nullifiers. Technical doc :drive.google.com/file/d/1oDq…
