Migration Guide
Extended is migrating from StarkEx to Starknet, with the migration process starting in the first half of July 2025. The exact start date will be communicated separately.
Please refer to this article to understand the rationale behind the move to Starknet and our longer-term vision for building the Extended ecosystem.
Overarching Migration Logic
The migration will happen in three stages, outlined below. However, we encourage users to migrate as soon as possible, as points will only accrue on the Starknet version of the exchange from the beginning of the migration process. Additionally, we expect better liquidity on the Starknet instance.
Existing Extended users will need to migrate from the current StarkEx instance to the new Starknet instance, following the logic described below. With the launch of the Starknet instance, users will experience no disruption in their trading experience. Starknet will function purely as a settlement layer, with all chain-specific logic fully abstracted. This means:
EVM users will not need to set up a Starknet wallet or interact with the Starknet network for deposits or withdrawals.
Near-instant deposits and withdrawals will be supported across six major EVM-compatible chains, with Solana integration coming soon.
At any given time, only one version of the exchange will be available to each user — StarkEx before migrating, and Starknet after migrating. Once a user migrates to Starknet, they will no longer have access to the StarkEx version.
Existing StarkEx users who have no funds in their accounts but have vault balances and/or accrued points will be automatically migrated to Starknet at the beginning of Stage 1.No user action is required. Both vault funds and points will be seamlessly transferred to the Starknet instance.
After the migration begins, all new users will be onboarded directly to the Starknet instance.
Migration Stages
Stage 1: Dual Operation Mode
Duration: 2 weeks from the launch of the Starknet instance
Description: During this stage, both StarkEx and Starknet instances will be fully operational for trading. Existing StarkEx users are encouraged to migrate at their convenience.
StarkEx Trading: Fully operational
StarkEx Deposits & Withdrawals: Fully operational
StarkEx Vault:
New deposits are disabled
All vault positions are closed
The vault continues to collect fee distributions and process liquidations
Points: Distributed exclusively on Starknet. Once a user completes the migration, all points accrued on the StarkEx instance will be automatically migrated to the Starknet instance of the exchange.
Stage 2: StarkEx Wind-Down Mode
Duration: 2 weeks after Stage 1
Description: Users are strongly encouraged to complete their migration to Starknet during this period. The StarkEx instance begins winding down and limits trading activity.
StarkEx Trading: Switched to reduce-only mode. Users can only decrease their exposure; opening new positions or increasing position sizes is disabled.
StarkEx Deposits & Withdrawals:
Deposits: Disabled
Withdrawals: Both Fast and Slow withdrawals are fully operational
StarkEx Vault:
New deposits are disabled
All vault positions are closed
No fee distributions
Vault stops processing liquidations — these will be handled by a separate insurance fund
Points: Distributed exclusively on Starknet. Once a user completes the migration, all points accrued on the StarkEx instance will be automatically migrated to the Starknet instance of the exchange.
Stage 3: StarkEx Freeze
Duration: Begins after Stage 2 and continues until all users withdraw their funds.
Description: All remaining positions on StarkEx will be force-closed at the latest Mark Price. The trading interface will no longer be available. Users will only be able to withdraw remaining funds through a dedicated withdrawal UI using the slow withdrawal mechanism. To access the Starknet instance of the exchange, users will first need to complete a slow withdrawal from StarkEx. Once the withdrawal is processed, they will be able to log in to Extended’s Starknet instance.
StarkEx Trading: Disabled. All positions force-closed at Mark Price
StarkEx Deposits & Withdrawals:
Deposits: Disabled
Withdrawals: Only slow withdrawals are supported through a dedicated withdrawal UI
StarkEx Vault:
The vault is shut down
All user funds are returned to depositors
Users must withdraw these funds via slow withdrawals
Points: Distributed exclusively on Starknet. To access points accrued on the StarkEx instance of the exchange, users must first complete a slow withdrawal from StarkEx. Once the withdrawal is processed, they will be able to log in to Extended’s Starknet instance and access their points balance.
Migration Process: User Flow
Users will be guided through a dedicated migration page that handles all required steps. The process includes:
Close All Open Orders and Positions. Close all open orders and positions across all sub-accounts.
Consolidate Funds. Move funds from all sub-accounts into a single sub-account of your choice.
Starknet Account Setup. Sign two messages: one to create your Starknet account, and another to verify ownership and enable trading.
Vault Funds. Funds held in the StarkEx vault do not require manual withdrawal. They will be migrated automatically.
Once all of the above steps are completed, go to the Migration page and click “Migrate.” The StarkEx interface will then transition to the Starknet UI.
Your funds—including your vault balance—will typically arrive within 45 minutes, though in rare cases, it may take up to 6 hours. You will receive a notification once the transfer is complete.
As mentioned above, existing StarkEx users who have no funds in their accounts but have vault balances and/or accrued points will be automatically migrated to Starknet at the beginning of Stage 1. No user action is required. Both vault funds and points will be seamlessly transferred to the Starknet instance.
⚠️ Please note: After migration, the StarkEx version of the exchange will no longer be accessible.
Migration for Referrals and Affiliates
Before the Affiliate Migrates to Starknet
As long as you remain on StarkEx (before it is frozen), you will continue to receive commissions for referrals who also remain on StarkEx. However, you will not earn commissions for any referrals who have migrated to Starknet until you migrate as well. Once you migrate to Starknet, you will begin earning commissions and points for all of your referrals on Starknet, including those who migrated before you.
Starting with Stage 1, it will no longer be possible to create new referral links or activate referral codes on StarkEx. New users who join via your existing referral link will be onboarded to the Starknet version of the exchange. You will start earning commissions for their activity after you migrate to Starknet.
After the Affiliate Migrates to Starknet
Once you have migrated to Starknet, you will earn both commissions and points for all referrals who have also migrated. However, you will not earn commissions or points for referrals who remain on StarkEx until they migrate as well.
⚠️ Please note: Starting from Stage 1, affiliates and their referrals on StarkEx no longer receive points for their activity. Points are only accrued on Starknet.
Migration for API Traders
The API endpoints on the Starknet instance of the exchange will remain the same as those on the StarkEx version. However, the signing scheme will change.
You can find an example of the new Starknet signing scheme here. For your convenience, we’ve also prepared a Python SDK for the Starknet instance of the exchange.
We strongly encourage you to begin implementing the Starknet signing scheme as soon as possible to ensure a smooth migration. Our testnet is already live on Starknet Sepolia, and you can test your integration there.
If you have any questions, feel free to ask the team in the Discord #devs channel.
