Steak with Drake @DrakeBreeding

Over 1% of CRCL is held as tokenized stock, over $280M, more than any other publicly traded company in the world. What year the flippening?

Guess who? 🤔

cirBTC is live on @ethereum. Circle helped establish the institutional standard for dollar collateral with USDC. Now cirBTC brings that same approach to Bitcoin, bringing 1:1 BTC-backed collateral to institutional DeFi markets with neutrality, transparency, and Circle infrastructure. Arc is next. circle.com/blog/cirbtc-is-no…

As Arc approaches mainnet, we’re opening the network. Starting today, developers can spin up a testnet node, inspect the code, and actively test and challenge Arc through our live bug bounty on HackerOne. → Arc Testnet code is now open-source → The Arc bug bounty is live on @Hacker0x01 → Developers can run their own Arc nodes Inspect it. Test it. Validate it. Blog: arc.network/blog/open-sourci… Bug Bounty: hackerone.com/circle-bbp

Circle announced the quantum-resistant roadmap for its L1 blockchain Arc, adopting a phased approach to full-stack quantum resistance across wallets, private state, validators, and infrastructure. The mainnet will introduce post-quantum signatures with an opt-in model. Circle added that quantum computing could threaten public-key cryptography by 2030 or earlier and warned of “harvest now, decrypt later” risks.

Virtuals is excited to support the agent economy on Arc. USDC settles 98.7% of all agent-to-agent payment volume today. @circle built @arc to be the settlement layer for that future: dollar-native gas, sub-second finality, nanopayments to six decimal places. Virtuals is building the layer on top: the infrastructure for agents to discover, negotiate, escrow, and settle every deal on Arc. Now live and available on Arc's testnet today.

The entire row is alllllll yours. Welcome to United Relax Row, three adjacent United Economy seats with adjustable leg rests that can each be raised or lowered to create a cozy lie-flat space for stretching out... You'll also get a mattress pad, blanket and two pillows. If you’re traveling with kids, a plushie too! United Relax Row will be available starting next year on more than 200 of our 787s and 777s, each with up to 12 of these brand-new rows. united.com/Elevated

How do Circle’s Nanopayments work? @circle has unveiled a new feature called Nanopayments. It allows transfers as small as $0.000001 while claiming zero gas fees. How is that possible? The secret lies in batched settlement. If every payment created its own onchain transaction, gas costs would quickly add up. Instead, Nanopayments collects users’ offchain payment signatures through the Circle Gateway. The system calculates net balances and periodically settles accumulated payments in a single batch. How Nanopayments Work Here is a simplified look at the process: 1. Deposit: The buyer sends USDC from their wallet to the Circle Gateway Wallet. This is an onchain transaction and gas is paid only once at the initial deposit. 2. Request and negotiate: The buyer requests a paid resource from the seller. The seller can respond through the x402 protocol. 3. Sign authorization: The buyer signs an EIP-3009 message. This is an offchain signature that authorizes payment to the seller and requires no gas. 4. Settle and serve: Circle Gateway verifies the signature and checks the buyer’s balance. The corresponding amount is locked. The seller immediately delivers the paid resource to the buyer. 5. Batch settlement: The Gateway periodically aggregates pending offchain signatures, calculates net balances, and settles them onchain in a single transaction. In other words, thousands of offchain payment transactions are consolidated into one onchain transaction. That is why the effective gas cost approaches zero. Security Model One point worth highlighting is that the offchain payment authorization process might appear custodial at first glance. However, Circle Gateway is designed to be non custodial. Circle Gateway runs inside an AWS Nitro Enclave TEE. Within this environment, the system verifies EIP-3009 signatures, computes batch settlement results, and signs the final batch transactions. The TEE signing keys are securely protected using AWS KMS. Even Circle employees cannot access the enclave or the keys. Thoughts There have been many attempts to implement micropayments. Most approaches simply relied on sending transactions on networks with extremely low gas fees. Nanopayments takes a different path. By aggregating offchain transactions and processing them in batches, it dramatically reduces gas costs. (For reference, the USDT chain @Stable has implemented a similar concept at the network level called the USDT Transfer Aggregator.) This approach could become especially meaningful in the future. As the agentic economy evolves, AI agents may increasingly stream payments in real time. Nanopayments creates the infrastructure that makes that model viable.
