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.
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.
Full details can be found in the documentation: docs.extended.exchange/about…

A supercycle of new onchain assets is now here, and visionary teams like @Morpho are building the next generation of financial infrastructure on @USDC and @arc to make them useful.
“Our belief is that tokenized equities will be the largest demand driver for tokenization onchain, since the birth of stablecoins.”
- @stablenzo from @circle during @Vault__Summit Singapore
Our goal is, and always has been, making @USDC the world's most useful and trusted digital dollar. This has been made possible by commercially engaging with the best distribution partners across both crypto-native and traditional industries. Excited to continue growing the pie for all.
USDC is the most useful stablecoin in the world because 150+ global partners build on it and share in its growth. In H1 2026, that meant $819M paid out to our partners.
I wrote about how the model works, what we reinvest to make the network stronger, and why every customer can always redeem for free.

The ghost is still hungry 👻 Starting with @maplefinance’s syrupUSDC last week, more productive, novel collateral assets are coming to @aave on @arc in the weeks ahead.

It was a blast sitting down with @NYSE to talk about the future of money and how everything we're building at Circle, including @USDC and @Arc, focuses on expanding financial access worldwide.
