Arc Mainnet is live.
Arc launches as the Economic OS for the internet: an open platform for global markets, real-time value movement, tokenized assets, and agentic economic activity.
Arc is more than a blockchain.
It launches as a full-stack financial platform with assets, applications, interoperability, developer infrastructure, and Circle platform services live from day one.
Arc delivers USDC as native gas, deterministic sub-second finality, EVM compatibility, and institutional validators.
It integrates with Arc Studio, App Kits, Arc Portal, Circle Agent Stack, CCTP, Gateway, CPN, and StableFX.
A complete economic platform at genesis.
Arc launches with infrastructure for:
→ Agentic economic workflows
→ Lending and borrowing
→ Trading and liquidity
→ Onchain FX
→ Payments and settlement
→ Tokenized assets
→ Exchanges, wallets, custody, compliance, data, and developer tooling
190+ institutional and ecosystem builders are building across Arc.

Mid-flight engine replacement complete✅
Shoutout to our chad engineers led by @dk_extended & @spooky_x10 for landing the plane with GitHub on fire, and to the @arc team for the runway.
Zero trading downtime on a volatile day.
Extended now settles on @arc.
The migration of $120 million in TVL is complete, with open positions and orders carried across. Trading continued throughout the process.
What this means for our users:
• Faster deposits and withdrawals, leveraging Arc’s sub-second finality.
• Native USDC transfers through Circle’s CCTP.
• cirBTC is now the BTC collateral asset.
Deposits and withdrawals are open again.

USDC supply on @Arc rose $220M (+42%) over the last week, to $742M - that's the highest daily level since Arc's launch on Sep 16 👀
At the same time, @circle minted $891M of USDC on Arc and burned $671M, EURC supply fell from $7.4M to $6.9M and GBPA supply did not change.
This new record high comes as DTCC plans to connect Arc to its tokenization service in 2027.

Extended moves to @arc on Thursday.
Settlement migrates from Starknet to Arc on October 22 at 13:00 UTC. The migration is planned with no interruption to trading. Positions can still be liquidated during this time, so top up margin beforehand. Transfers between sub-accounts stay open.
Most accounts need to do nothing. Your account, sub-accounts, positions, orders, history, points and keys carry across unchanged. USDC migrates as native USDC, ETH migrates 1:1 as wETH, and Vault (XVS) balances and withdrawal rights are preserved.
If you hold more than $1 of USDT or wBTC in any sub-account, you must act by 12:00 UTC on October 21:
- Authorise the conversion in-app. USDT converts to USDC and wBTC to cirBTC at 1:1 during the migration, with no swap fees. Extended credits a 0.50% premium.
- Or withdraw both assets.
If you miss the deadline, your whole account will be restricted for up to 30 minutes on October 21 while Extended cancels orders, closes positions in the affected sub-accounts at mark price with no fees, and returns your USDT and wBTC to your login wallet.
Deposits and withdrawals will be paused for up to 2 hours during the migration.

Most teams building with stablecoins want to ship a product, not assemble a blockchain stack.
@crossmint is bringing wallets, money movement, compliance tooling, embedded finance, and agentic infrastructure to Arc.
That gives builders a faster path to:
→ Stablecoin payments
→ Cross-border remittances
→ Embedded wallets
→ Financial apps that feel familiar to users
Arc provides the stablecoin-native execution layer underneath.
