Deposits and Withdrawals

Since Extended smart contracts are deployed on the Ethereum blockchain and currently support only USDC as collateral, all native deposits and withdrawal requests are processed in USDC on the Ethereum blockchain.

For user convenience, we also support USDC deposits and withdrawals on Arbitrum for amounts under $50,000. This limit will be increased in the future.

Deposits

For deposits please note the following:

  • Users must cover the gas costs of their deposits, which means you need to have ETH on the chain you are depositing from in your connected wallet to cover these costs.

  • There is no minimum deposit requirement.

  • After a deposit is submitted, on Ethereum, we wait for 10 blocks (~2 minutes) before accepting it on the exchange. Deposits from Arbitrum are processed in under 30 seconds.

  • You can track the status of your deposit in the 'Transfers' table in the UI.

Withdrawals

We support two types of withdrawals: fast and slow. Extended doesn't charge fees on both types of withdrawals, but there are differences in processing.

Fast withdrawals:

  • On average, fast withdrawals are processed within 15 minutes, but in rare cases, they may take up to 1.5 hours.

  • The combined withdrawal limit for both Arbitrum and Ethereum fast withdrawals is $50,000 per 12 hours. This limit is expected to increase in the future.

  • A 1.1x multiplier on the current gas fee is applied to ensure transaction settlement in case of gas cost volatility.

  • In rare cases, fast withdrawals may be temporarily unavailable due to liquidity gaps in the exchange's Ethereum and/or Arbitrum wallets. If this occurs, please consider using slow withdrawals or trying again later.

Slow withdrawals:

  • With slow withdrawals, users can only withdraw USDC to Ethereum.

  • Slow withdrawals involve a two-step process. The first step initiates your withdrawal request, which is processed on Layer 2. Once your funds are ready (this can take up to 12 hours), users will receive a notification to claim funds to their wallet and at this point users need to cover the gas fees.

  • There is no maximum limit on the amount for slow withdrawals.
