how a private stablecoin transfer should feel: open your wallet. toggle private on and hit send. no one else can see it. how it actually works on Arc : configurable privacy at the protocol layer, encrypted state in hardware enclaves, master key threshold-split across validators, post-quantum from day one....

configurable privacy at the protocol layer. apps and assets decide what stays private: transactions, balances, contract state, workflows. The same wallet holds public and private. The same solidity deploys in either execution environment (private EVM compatibility!)

encrypted state in hardware enclaves + threshold-split master key signing private state runs inside TEEs (AWS Nitro Enclaves), isolated from the host OS and the validator operator. the decryption key is split across the validator set. NO SINGLE party can decrypt alone

post-quantum from day one. confidentiality today has to hold against a future quantum computer that can break ECC. Arx uses X-Wing (ML-KEM-768 + X25519) a hybrid KEM combining classical and post-quantum security. harvest-now-decrypt-later doesn't work here.

selective disclosure, on your terms. view keys let you or a counterparty (auditor, admins etc) reveal specific transactions, balances, or contract state whether for compliance, audit, or verification. Private by default and auditable when you choose. One network. One send. No one else sees it unless you say so Full design in the arc privacy whitepaper

@arc 100 percent crazy how much is going on under the hood, but how simple the UX is

X-Wing on the wire is the right call, and it settles harvest-now-decrypt-later for transport only. The threshold-split key is the part to read carefully: a quorum of validators can reconstruct it and decrypt every past state, so confidentiality holds as long as no quorum ever colludes, for as long as the ciphertext matters. That is a governance guarantee rather than a cryptographic one, and a different promise from ZK privacy, where no set of parties can. The other classical leg is attestation: a share is only released to an enclave the validator believes is real, and Nitro attestation documents are signed with ECDSA P-384, so the post-quantum story ends at the attestation root until that moves too.

@arc Great feature! I’ll try it out in a bit. Is the long-term goal for privacy to extend beyond transfers to other onchain activity as well?

We are excited to announce the launch of QShield Terminal, the world's first Quantum-Secured Privacy Terminal for Ethereum. QShield brings full financial privacy to Ethereum without the need for mixers, tumblers, or any third-party tools. Everything is handled directly through the QShield interface using zero-knowledge proofs on RAILGUN Protocol. What QShield Terminal offers today: • Shield any ERC-20 token from your public wallet into a fully private balance • Send and receive tokens with zero on-chain trace • Create multiple independent shielded wallets • Transfer between your own shielded wallets with no connection between them on-chain • Switch between public wallets to fund your shielded balance from any wallet you own • Support for ETH, USDC, USDT, DAI, WBTC and 290+ ERC-20 tokens • Quantum entropy wallet generation using real quantum randomness • 100% web-based, no downloads, no browser extensions No mixer. No tumbler. No compromises. Just real privacy through cryptography, accessible to everyone directly from the browser. This is the first product of its kind. No other privacy solution combines multi-shielded wallets, inter-wallet transfers, quantum entropy, and a full guided interface in one place. You can try it now: We are working on additional features including private token swaps directly from your shielded balance, and we will keep expanding the protocol with new capabilities over the coming period. We keep building. RAILGUN - Private Ethereum DeFi

Private transactions between wallets now possible on Solana using ZERAs Private Cash Addresses. A closer look at last week’s MVP drop: Private P2P. Most "privacy" on Solana still falls back to withdraw-to-address (recipient + metadata leaks) or multi-step send flows that leave trails. Our P2P is different: one atomic in-pool transaction, the sender’s note is nullified, and two new encrypted notes are created, all inside the vault. No stepping out. No re-deposit choreography. Why it’s so hard to deanonymize: ✅ Your Private Cash Address has zero link to your Solana wallet: it’s an X25519 keypair derived from a wallet signature, and the public key becomes your private address. ✅ Notes are encrypted with NaCl box using a fresh ephemeral key every send, meaning even two payments to the same person looks unrelated. ✅ Recipients discover incoming notes via trial decryption, the chain never learns "who owns what." While we have immense respect for those building privacy on Solana, we are proud to be the first to achieve one-shot, in-pool P2P with full privacy. To our knowledge, this remains an industry first. This is the difference between hiding balances inside a pool and moving value privately between people. Note: Right now, the sender’s wallet still signs the private transaction, so on-chain you can see that a wallet performed a P2P action, but the amount and recipient remain private. The upcoming P2P Relayer removes that footprint too, completing the "cash-style" flow with no on-chain sender trace. What’s coming next: ✅ More assets: At least SOL + ZERA alongside USDC. ✅ P2P Relayer: A decentralized signing/relaying network that can submit transactions for you — enabling withdrawals with minimal linkage after the initial deposit, and removing the sender’s on-chain P2P footprint. Try it out in the ZERA Dashboard below ⤵️
