Circle just designed @Arc to be quantum-resistant from the very first block - and most people building onchain haven't fully processed what that means.
Every wallet, every transaction, every smart contract on every EVM chain today is secured by elliptic curve cryptography. Shor's algorithm, running on a sufficiently powerful quantum computer, breaks all of it.
The threat isn't waiting for Q-Day to start. Harvest-now, decrypt-later is already live. Adversaries collect encrypted onchain data today and hold it until quantum hardware catches up. Every public key ever exposed on any chain is already in that exposure window.
NIST finalized the post-quantum standards in August 2024 - ML-KEM (FIPS 203), ML-DSA (FIPS 204), SLH-DSA (FIPS 205). The industry migration deadline is 2030. The clock is running.
What @circle built into Arc is the only answer that makes architectural sense: quantum-secure signatures live at mainnet launch, from block one. Not retrofitted. Not a future hard fork. ML-DSA, CRYSTALS-Dilithium, Falcon - built in from genesis, opt-in, no forced migration, no network reset.
The rollout covers the full stack. Wallet signatures at launch. Private VM layer next - confidential transfers shielded, public keys wrapped in symmetric encryption. Then infrastructure: TLS 1.3 with X25519MLKEM768 hybrid key exchange, HSMs upgraded. Finally validator authentication - moved only after performance testing confirms sub-second finality holds.
Wrote a full breakdown in the Arc House India chapter - why this architecture matters, what the real tradeoffs are, and why this is directly relevant to anyone building payment infrastructure in India right now.

We will build the largest developer community in the world.
I want to meet the best developers and listen to what they need, what the feel is missing and what unique support we could bring to cement their ability to be successful
Then we will build it
Our CEO @mgault is speaking on this space later today, on:
*AI Agents Go Autonomous*
Who is building the agent economy in crypto

We spent 15 years securing critical systems
We're now securing AI agents
Built and exited Guardtime: secured Estonia's digital infra, NATO supply chain
PhDs: ML, cryptography, CS.
Blockchain pre BTC
Microsoft, Nokia, Barclays, JP Morgan
The team that built security infra for govt and defence is now building for autonomous AI
Checker for $SPARK is going live tomorrow
And TGE will be on the 18th!!
If you previously dropped your wallet address to IdeaRalph or Spark, unfortunately, we couldn't fetch a large part of it due to X API not seeing all the comments.
Prechecker went live for this, but a lot of people probably missed that, so we want to give one more chance to everybody before the airdrop.
Drop your 0X wallets and look for the next instructions, as we want to make sure we leave no one behind.
Thank you 🙏
Half right. Agents need permissionless, frictionless rails - that part is DeFi-shaped. They don't need a shared ledger, and at agent volumes they can't have one. The interesting work is what replaces it. Unicity is rebuilding DeFi's foundations on a new atomic primitive: self-authenticating tokens, validation at the edge.

We gave your agents voice and ears. And let them pay as the go.
👇
Use wallet-authenticated WebRTC voice, speech-to-text, and text-to-speech APIs for AI agents.
16 endpoints are available for realtime voice sessions, transcription, speech synthesis, and programmable voice workflows.
