@bullrunalpha Those targets are all over the place, 157 to 243 is a huge spread for the same event. Curious which analyst actually ties their number to Arc mainnet metrics like USDC settlement volume versus just extrapolating stablecoin market share.

$CRCL — Mainnet is almost here. Circle price targets: $243 from Citi: +301.9% $190 from Bernstein: +214.3% $160 from Clear Street: +164.6% $157 from Aletheia Capital: +159.7% $USDC $EURC $USYC #Arc #Blockchain

@Panchu2605 @arc @USDC @samconnerone @bobbilee @AdiSeredinschi @TxnSheng @0xmikef @jerallaire @BuildOnCircle Curious how gas estimation handles rounding at the boundary between the two decimal representations, especially for contracts doing tight math on fees. Also does the precompile sync happen pre or post block execution? That timing detail matters a lot for MEV-sensitive apps.

One Dollar, Two Interfaces: How USDC Actually Works on @Arc everyone knows gas on Arc is @USDC. it's the headline feature, the thing every thread repeats. but almost nobody has looked one layer down at how that actually works - because making a 6-decimal stablecoin serve as the native currency of an 18-decimal virtual machine is not a trivial problem. it's a real engineering conflict, and Arc's solution to it is one of the quietest, cleanest design decisions on the whole chain. we hit this on day one of building on Arc. here's what's going on under the hood. two facts that don't fit together: - the EVM assumes its native currency has 18 decimals. gas metering, msg.value, every tool in the ecosystem, all built on wei-scale math - USDC has 6 decimals. on every chain, in every integration, in every contract that's ever composed with it if USDC is going to be the gas token, which one wins? pick 18 and you break compatibility with the entire USDC ecosystem. pick 6 and you fight every piece of EVM tooling ever written. Arc's answer: don't pick. run both. The design: on Arc, USDC exists through two interfaces at the same time: - a native interface with 18 decimals - this is the gas token. it pays transaction fees, it's what getBalance() returns, it lives in the account's native balance field - an ERC-20 interface with 6 decimals at 0x3600000000000000000000000000000000000000 - standard balanceOf, transfer, approve. exactly the USDC every contract already knows how to talk to and the part that makes it work: a precompiled contract keeps both representations perfectly synchronized, every block. 1e18 native units equals 1e6 ERC-20 units. same dollars, two views, zero duplication. look at that address again. 0x3600...0000 isn't a random deployment - it's a reserved system address. USDC isn't a token that someone deployed on Arc. it's part of the chain itself. What this looks like in a real codebase when we built @Xylonet_ , we standardized on one rule: application logic speaks ERC-20, and only ERC-20. - every balance read across our swap, vaults, pools, and bridge goes through the ERC-20 interface at 0x3600...0000, always at 6 decimals - every parseUnits and formatUnits call in the app pins to 6 - the same code we'd write for USDC on any EVM chain - the native 18-decimal side never appears in our application code at all. it does exactly one job: silently paying for gas - our tipping contract escrows USDC the same way any ERC-20 escrow works. nothing custom, nothing chain-specific the payoff is that our entire stack - viem, wagmi, standard ERC-20 ABIs - worked unmodified. Arc absorbed the complexity so integrations don't have to. one warning for anyone building: if your SDK or indexer shows a "native" balance and an "ERC-20" balance for the same address, that is the same money through two windows. never add them together. Circle's own docs flag this - it's the one mistake the design makes possible, and it's fully avoidable if you pick one interface for reads and stay consistent. Why this matters beyond the trivia this is what stablecoin-native actually means at the protocol level. not "we added USDC support" - every chain has that. Arc restructured the base layer so that the dollar is simultaneously the fuel and the asset, without breaking a decade of ecosystem conventions on either side. and the best part is who notices: nobody. users hold dollars and pay fees in cents. developers write the same code they've always written. the entire mechanism disappears into the background, which is exactly what good financial infrastructure is supposed to do. the loudest features get the threads. the quiet ones get the adoption.

Privacy ≠ anonymity. Archionary is building the infrastructure layer that makes confidential transfers, selective disclosure, and compliance-ready privacy usable for every developer building on @arc — no cryptography PhD required. Building in public. Stablecoin infrastructure, payments privacy, onchain finance — this is day one. What would you build first if payroll and treasury could finally go onchain, privately?

Stablecoins finally have a home onchain with @arc — built by @circle, gas paid in USDC, sub-second finality. But payroll, treasury, OTC desks — the real financial workflows — still can't move onchain. Every amount, every counterparty, fully public. That's the gap we're building for.
