Watch this space
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…

.@arc has cleared $18.71B in stablecoin transfer volume since mainnet opened five weeks ago.
↳ Stablecoin supply on the chain sits at $897M, its highest since launch and 68% above the late-September low
↳ Every dollar of that supply has turned over more than 20 times in five weeks
Eco has been live on Arc since mainnet opened, building one integration that connects the chain to where the rest of the market’s dollars sit.
Data: @dune
Eco is live on @Arc, alongside its mainnet launch!
Arc runs on stablecoins as gas, starting with @USDC, with sub-second settlement and dollar-priced fees.
Eco is building on Arc to connect the open, EVM-compatible L1 chain to the rest of the market: real-time stablecoin transfers between Arc and every major chain, through one integration.
