More than 100 applications and institutional/ecosystem builders are part of the Day-1 ecosystem .
This isn't just another chain launch
Arc Mainnet is now live
The next chapter of internet-native
finance starts today .
1 DAY UNTIL @arc MAINNET
If you're waiting for launch day before exploring the Arc ecosystem, you may already be behind.
The advantage isn't chasing what everyone is talking about. It’s knowing what’s being built early, understanding the teams, and identifying where activity could emerge as liquidity starts flowing.
Here’s my Arc Day 1 watchlist 👇
I’ll keep updating this list as the ecosystem expands.
1. LAUNCHPADS 🚀
@ArcadeSwap
→ Bonding-curve launches + direct Uniswap V4 launches.
@synthra_finance
→ AMM, aggregator and launchpad with token buyback mechanics.
@SharcFun
→ Launchpad + Telegram trading tools, copy trading and cross-chain OTC.
@Bigshortdotxyz
→ Token launches with long/short markets for memecoins.
2. DEFI / DEX 🔄
@Xylonet_
→ Fast swaps and bridging infrastructure.
@lunya_io
→ V3 AMM, bonding-curve launchpad and CCTP-powered USDC bridging.
@UnitFlowFinance
→ Swaps, payments, prediction markets, bridging and lending.
@synthra_finance
→ An all-in-one DeFi and trading hub.
3. PAYMENT INFRASTRUCTURE 💳
@PulsarMoneyApp
→ Consumer-focused financial infrastructure being built on Arc.
@Xylonet_
→ Stablecoin DeFi and social tipping powered by Arc.
4. PREDICTION MARKETS 🎯
@kairo_market
→ Permissionless prediction and perpetual markets on Arc.
@Predarc_

5. NFT MARKETPLACES
@opensea
→ NFT marketplace and launchpad .
@Orixaxyz
→ Native NFT marketplace for the Arc ecosystem .
@SharcBay
→ NFT marketplace and launchpad
This is only the starting point.
Arc Mainnet goes live tomorrow.
Once liquidity, users and builders start converging, the ecosystem could move very quickly.
Not every project will succeed. That’s part of the game.
Do your own research.
Study the teams.
Understand the products.
Find the builders before the crowd.
Day 1 is where the next wave begins. 🌊
Shoutout to my friends at @solana_devs today.
@USDC Bridge now supports @Solana
You can now move @USDC directly between @Solana and 18 supported ecosystems (including @Arc) through the USDC Bridge.
Connect your wallet, choose Solana as your source or destination, enter the amount, and confirm your transfer. USDC Bridge provides a direct, predictable experience for accessing Solana apps, liquidity, and market opportunities without fragmented bridging flows.
USDC Bridge: Powered by CCTP by Circle.
Move USDC to or from Solana: https://t.co/FLvWLxjyQQ
New in Arc Studio.
Teams can now request a one-time usage limit increase when their organization is running low.
Get one month of higher shared allowance across your org, so every member can keep building without interruption.

Pulsar is building a stablecoin-native money app on Arc.
The goal: help people hold, convert, transfer, and spend across currencies from one unified experience without making them manage chains, bridges, gas, or routing.
Under the hood, Arc gives @PulsarMoneyApp the infrastructure for:
→ USDC-based fees
→ Deterministic finality
→ USDC and EURC flows
→ StableFX for currency conversion
→ Circle infrastructure for crosschain stablecoin movement
Stablecoins become the product ingredient, not the product interface.

iTrustCapital has launched Q, an integrated set of AI-formulated quantitative trading strategies available directly inside client accounts.
Users choose a predefined strategy, after which Q monitors market signals and automatically executes buys or sells according to fixed rules.
The aim is to reduce emotional decision making while keeping everything within the platform no third-party apps, external bots, or separate technical setup required.
The feature supports automated management across cryptocurrencies in accounts such as crypto IRAs .
Illustrative historical figures shown by the firm include multi-year hypothetical returns for strategies focused on Bitcoin, XRP, Ethereum and a broader “Quantum” approach; these are net of applicable fees, derived from historical data, and do not represent actual client results.
Past performance is not indicative of future results. Investing involves the risk of loss, and no strategy guarantees profit or protection against declines

OpenAI’s DevDay 2026 conversation with Thibault Sottiaux is one of the clearer signals yet of where the product surface is actually heading.
The shift that stands out is not another model benchmark.
It is the move from a chat interface that waits for a prompt to always on agents dots that keep a persistent cloud computer, connect across thousands of tools, and continue working toward goals while the user is elsewhere.
Calling them, receiving updates in Slack or Teams, and letting them run background work changes the interaction model more than another jump in reasoning scores .
The chat box was the on ramp .
The interesting question is whether it becomes the limiting factor once agents can hold context, use tools, and act across systems without constant steering.
The model split is equally practical. GPT-6.1 Sol is positioned as near-Astra capability on coding, computer use, and office work at a fraction of the cost, while Astra powers the higher-end agent layer.
That pricing and capability ladder matters more for adoption than raw leaderboard numbers.
Most organisations will not run their heaviest workloads on the top tier; they will route work across tiers.
The rebuilt desktop app, shipped in under 30 days with the models themselves, and the discussion of agents still failing on multi-step reliability, both point to the same constraint: the bottleneck is no longer generation quality alone. It is reliable execution, evaluation, and knowing when to hand control back to a human.

Building on @arc just got Easier
I started exploring Arc Studio few days after it was lauched and its been a fantastic adventure so far
coding just got easier on Arc Studio
i created a DEX and a Cross chain bridge on Arc studio, connected it to my wallet and executed a bridge on arc testnet...
a video illustration is attached below
Build on @arc
Invest in @arc
Grow with @arc@bobbilee@samconnerone@silencexlm
Just watched the full interview with @thsottiaux
on OpenAI’s DevDay updates. The sections on ChatGPT Dots as always-on agents with their own cloud computers, the GPT-6.
1 Sol vs Astra trade-offs, and how agents are actually being used internally are especially practical.
Worth the time if you’re evaluating persistent AI workflows or the current product direction .

Build crypto-backed borrowing into your app on Arc.
We open sourced a USDC Borrowing sample app using Borrow Kit.
It walks through the full flow: discover a market, size a loan, deposit cirBTC as collateral, borrow USDC, monitor health, repay, and close.
No custom smart contract code. No direct lending protocol integration to maintain.
Clone it and start building: https://t.co/Pv8iQhFQoy
