Extended becoming Arc native. Trade anything. This is a very exciting launch.
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.

Huge moment for @arc. Welcome to the fam, @extendedapp. Extended will power @USDC derivatives on a wide range of assets, from crypto to RWAs and beyond.

Smooth UX
Congrats to the @architectpay team. Now live on @arc mainnet.
Gasless stablecoin payroll and payments for small businesses.
One @USDC balance. One EURC balance. No chain to pick, no gas token to hold.
Bitcoin can anchor a balance sheet, but institutions still need liquidity they can use.
cirBTC brings BTC into supported smart contract markets as collateral. USDC provides programmable, dollar-denominated liquidity for borrowing, repayment, and settlement.

Arc has got agentic game. So much more to come!
We're seeing the leadership at @Arc move fast into the agent space lots of posts about this narrative
Agent wallets and USDC payments for agents and now Crossmint all landed on Arc this week
OKX is expanding euro-native trading with EURC.
Through @okx’s unified EUR orderbook, users can convert EUR to EURC 1:1, access EURC trading pairs, and manage activity in euro terms.
Another step toward making EURC more useful across Europe’s crypto ecosystem.

Why does tokenizing CRCL through platforms like bStocks, Ondo & xStocks matter for Circle?
Circle is building a platform (Arc) & products (USDC, EURC) that serve global, competitive markets
Expanding access to CRCL outside the US can serve two purposes:
1) Economic: reach new investors, broaden demand for the stock & potentially lower Circle’s cost of capital
2) Strategic: give more people a financial stake in Circle’s success, potentially building local support for policies that enable its products
Global products benefit from a global investor base
We need more "Agent Exchanges"
We're expanding the Tolly Agent Exchange with detailed profiles that give users and AI agents deeper insight into the performance, activity and track records of service providers.
Each profile brings together key information in one place, including:
• Revenue, paying customers and transaction history
• Usage trends, success rates and refunds
• Available services and pricing
• Operator details and verification evidence
• Recent activity and economic performance
From discovering agents to evaluating their performance and exploring their services, we're bringing the information needed to make better decisions into one place.
Another step towards a more transparent and accessible agentic economy on @arc.
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.
