Claims
- Arc's public mainnet launched on 2026-09-16 as an open Layer 1 whose fees are paid in USDC with no volatile native token.
“Fees are paid in USDC, with no volatile native token required.”
· source - The askgrokwallet repository — the governed-wallet benchmark this idea rides — was still landing commits on 2026-09-15, including a change to its on-chain risk registry, so the wave is live now rather than stale.
“Don't publish a schema for a version that isn't signing yet”
· source - Arc denominates all transaction fees in USDC and treats USDC as the native gas token.
“Arc denominates all transaction fees in USDC, the native gas token.”
· source - On Arc a transaction must set maxFeePerGas to at least 20 Gwei or it may never be mined, which bounds how a pre-quoted 4am batch can be priced.
“Transactions submitted under this floor may remain pending indefinitely or fail outright.”
· source - USDC on Arc exists in two scales at once: an 18-decimal gas unit and a 6-decimal ERC-20 interface used by applications, so the displayed dollar figure and the encoded amount come from different decimal bases.
“USDC on Arc also provides a standard ERC-20 interface with 6 decimals for application-level transfers.”
· source - Arc's fee design promises that fee values returned by its RPC stay accurate for a reasonable submission window, which is what makes a dollar cost quotable before the order is armed.
“Dollar-denominated, bounded fees mean transaction costs map directly to a known USDC amount.”
· source - Circle frames Arc around agentic economic activity, citing USDC's share of agent-driven transaction volume.
“USDC accounts for 98.8% of agent-driven transaction volume”
· source - EIP-5792 is Final and defines the exact prepare-then-approve mechanism: an app asks a wallet to process a batch of on-chain write calls and to report their status.
“Defines new JSON-RPC methods which enable apps to ask a wallet to process a batch of onchain write calls and to check on the status of those calls.”
· source - As of WalletConnect's own September 2025 write-up, Safe was the only wallet that had added wallet_sendCalls support via WalletConnect, so one-tap batch approval cannot be assumed for an arbitrary mobile wallet.
“Right now, Safe is the only wallet that has added support for wallet_sendCalls via WalletConnect.”
· source - Arc targets the Osaka hard fork and supports EIP-7702 set-code transactions, so an ordinary EOA on Arc can batch and de-escalate privilege the way it can on Ethereum.
“hard fork as its baseline, including features such as EIP-7702 (set-code transactions)”
· source - EIP-7702 is Final and lets an EOA set code in its own account, which is the mechanism behind atomic batching and sub-key privilege de-escalation.
“Add a new EIP-2718 transaction type that allows Externally Owned Accounts (EOAs) to set the code in their account.”
· source - ERC-7715 (delegated execution permissions) is still Draft and its JSON-RPC method is wallet_requestExecutionPermissions, not wallet_grantPermissions.
“for DApp to request a Wallet to grant permissions in order to execute transactions on the user's behalf”
· source - Uniswap v2, v3, v4 and UniswapX all went live on Arc on 2026-09-16, with Uniswap Web App, Wallet and API support.
“Uniswap v2, v3, v4 and UniswapX are live on Arc”
· source - The UniswapX V3DutchOrderReactor is deployed on Arc mainnet (chain 5042) at 0x0000000015134054eA82AE0bb9fda66b36402C36, with contracts dated 2026-06-12 and SDK/service integration still pending.
“0x0000000015134054eA82AE0bb9fda66b36402C36”
· source - On iOS and iPadOS a web app may only request push permission after it has been added to the Home Screen and in response to direct user interaction.
“A web app that has been added to the Home Screen can request permission to receive push notifications as long as that request is in response to direct user interaction”
· source - The Push API delivers messages to a web app whether or not it is in the foreground or even currently loaded, which is what makes a 4am wake possible from a PWA.
“the ability to receive messages pushed to them from a server, whether or not the web app is in the foreground, or even currently loaded”
· source - Chainlink on Arc is testnet only, providing Data Feeds, Data Streams, CCIP and Proof of Reserve — and no Automation.
“Chainlink is available on Arc testnet, bringing Data Feeds, Data Streams, CCIP, and Proof of Reserve to Arc builders.”
· source - Chainlink Automation does not list Arc among its supported networks, and its v1.x and v2.1 lines were sunset on 2026-06-30 and 2026-07-31 with migration pushed to the Chainlink Runtime Environment.
“Chainlink Automation v1.x sunsets June 30, 2026 | v2.1 sunsets July 31, 2026”
· source - Stork's EVM contract-address list gives Arc a Testnet deployment at 0xacC0a0cF13571d30B4b8637996F5D6D774d4fd62 and no mainnet address.
“0xacC0a0cF13571d30B4b8637996F5D6D774d4fd62”
· source - The WalletConnect push server turns an incoming wc_sessionRequest (tag 1108) into a phone notification titled 'Signature required', which is how an app reaches a mobile wallet that is not open.
“title: Signature required body: You have a message to sign”
· source - Permit2 is deployed on Arc mainnet and testnet at its canonical address 0x000000000022D473030F116dDEE9F6B43aC78BA3.
“0x000000000022D473030F116dDEE9F6B43aC78BA3”
· source - The GeckoTerminal public API is rate limited to 30 calls per minute, shared across all endpoints and all of a product's users.
“The current rate limit for the Public API is set at 30 calls per minute.”
· source - GeckoTerminal serves Arc pools under the network slug 'arc' with per-window price_change_percentage and volume, including a trending pool showing roughly -30.5% over 24h at the time of the fetch.
“uniswap-v3-arc”
· source - Coinbase Spend Permissions let a designated spender move a capped amount of a token per period out of a smart account without any further signature, and are deployed on six mainnets, none of which is Arc.
“The amount of the token the spender is allowed to spend, in the token's smallest unit”
· source - DeFi Saver runs price-triggered automation through non-custodial contracts that fire only when the user's configured on-chain conditions are met — the allowance-backed version of what this idea does with a human tap.
“non-custodial smart contracts that only execute when your configured on-chain conditions are met”
· source - Uniswap shipped limit orders as a mainstream web-app feature for ERC-20 tokens on Ethereum in February 2024, establishing the signed-and-waiting conditional order as ordinary consumer behaviour.
“Users can now place Limit Orders for any ERC-20 token on Ethereum on the Uniswap web app.”
· source - Synthra is the chain-abstracted trading layer offering spot, liquidity and perpetual markets with on-chain settlement, and its V3 spot is the Arc venue that went live at mainnet launch.
“Synthra is the chain-abstracted trading layer: spot, liquidity and perpetual markets with CEX-like UX and on-chain settlement.”
· source - Synthra's swap surface binds a route to one executable quote and exposes raw calldata and approval requirements, but documents no limit, stop or conditional order type.
“Best execution compares Synthra V3 liquidity with the wider execution network and binds the chosen route to one executable quote.”
· source - Arc supports ERC-4337 and lists 13 account-abstraction providers, but its account-abstraction page publishes no EntryPoint address.
“Arc supports the ERC-4337 standard, so you can use any compatible bundler, paymaster, or SDK from the providers below.”
· source - Arc's RPC endpoint page lists public mainnet (5042) and testnet (5042002) URLs but still carries a credential requirement note attached to the private mainnet phase, so a production watcher should use a named provider endpoint.
“During the private mainnet phase, these endpoints are permissioned and require credentials.”
· source - OpenZeppelin Defender Monitor already provides the condition-watching layer with custom-code filters, so the 'scanner' half of the idea can be bought rather than built.
“Monitors allow you to gain full visibility into your smart contracts' risks and behaviors.”
· source - Arc reaches irreversible settlement in under one second via Malachite BFT, so the gap between the person's 4am tap and a confirmed fill is negligible.
“Arc's deterministic finality delivers irreversible transaction settlement in under one second.”
· source - The Safe Transaction Service accepts transactions so that off-chain signatures can be collected and owners are informed about pending transactions awaiting confirmation — the prepare-then-approve queue, already a shipped pattern.
“Transactions can be sent to the service, enabling off-chain signature collection.”
· source - Uniswap v4's Arc deployment publishes PoolManager 0x8366a39CC670B4001A1121B8F6A443A643e40951 alongside UniversalRouter, PositionManager, StateView and Quoter for chain 5042.
“0x8366a39CC670B4001A1121B8F6A443A643e40951”
· source - The askgrokwallet benchmark publishes plain-English policies, a human approval inbox and signed receipts, and its live contracts are on Base mainnet rather than Arc.
“0x4ACcB1df8cc625AC05743888158CC3B866aC9833”
· source - MetaMask implements wallet_sendCalls and exposes atomicRequired, so a batch is only atomic when the app asks for it and the wallet can honour it.
“Requests that the wallet submits a batch of calls.”
· source - Arc's fee docs instruct applications to present gas costs to users in dollars rather than Gwei, which is the chain endorsing the product's core UI promise.
“Because Arc denominates gas in USDC, surface fee estimates to users in dollar terms rather than raw Gwei.”
