Sigma confirms continued Arc trading following mainnet launch. Its official 14 September update separately documents Argus integration.
The mainnet-day update confirms ongoing Arc trading and highlights its Argus integration.
The 15 September post identifies the Sigma Telegram bot. The September 20 web review additionally confirms Arc access in the terminal. The existing announcement does not by itself establish feature parity or a speed or reliability ranking.
Official source ↗Availability evidence is not a custody audit or funded execution test. Check the wallet recovery procedure, permissions, current quote and withdrawal controls in the selected product. Keep USDC on Arc for gas. Product-wide rewards do not establish an Arc-specific net fee.
Official source ↗The earlier Arc announcement identifies Telegram trading. The September 20 review additionally records Arc in the Sigma web interface, with quick buy, quick sell and a copy setup entry. That newer observation extends access coverage without proving identical order behavior across the two surfaces.
Official source ↗The existing Argus announcement remains relevant to Arc. The newer Arc web review also observes Argus, Tolly Pad and ArcPad as discovery-filter labels. A label alone does not establish executable coverage or support for every bonding stage.
Official source ↗Sigma’s numeric Arc platform fee remains unconfirmed. Arc web settings expose slippage, liquidity, price-impact, tax and gas controls; check the quoted amounts before submitting. Arc-specific Telegram order types, limit orders, DCA and universal MEV protection are not established by this review.
Official source ↗Sigma has Web and Telegram access within one product and a shared wallet/login family. Wallet identity does not prove that positions, order history or rewards balances synchronize completely; those three synchronization behaviors remain unconfirmed.
Official source ↗The documented workflow supports creating or importing wallets, with up to ten wallets. Review the selected chain before copying a deposit address, retain recovery information privately and test the selected withdrawal workflow. The technical custody and key-encryption architecture have not been independently established.
Official source ↗Sigma’s standard referrer commission is 20% of referred users’ platform fees, with a conditional partner rate of 40%. These are referrer shares, not an automatic customer discount. Points, cashback ranks and referral earnings are separate; a universal effective cashback rate and cross-surface rewards balance synchronization remain unconfirmed.
Official source ↗These facts use Arc-specific evidence or explicitly approved product-wide information. “Not verified” is distinct from “No”.

A Arc-specific platform fee is not verified in the record. Check the quoted fee in the product before trading.
Rewards and referral programmes can have eligibility rules. The product-wide reward model is points; a Arc net fee or cashback rate is not calculated without a confirmed chain-specific schedule. Understand total trading costs →

A wallet label describes the recorded product model, not an independent security audit.
Check who can access signing keys, whether export is available and how recovery works. Keep USDC on Arc for gas. Fast finality is not a guarantee of a good fill, recoverable transfer or safe contract. Network-wide opt-in privacy is still in development; private execution and MEV claims need separate product evidence. Read the wallet and security guide →
Compare against other active Arc tools.
The current record marks the entity, trading service and Arc chain status as active. This is source-based availability, not a live trade or uptime test.
Not verified. This answer is scoped to Arc; other chains can differ.
Use the verified entry link, select Arc in the product and read its setup instructions. Check wallet recovery and the current fee quote before committing funds.
The review date indicates a source check, not a claim that every field was retested on that date.
