# Deposits and Withdrawals

Depositing assets into ULTRADE is done as one simple native transaction on the blockchain of the deposited token. Deposits are credited based on the length of time it takes to reach finality on that specific blockchain. The table below provides the estimated deposit finality time in each chain. The gas cost for deposits is the typical transaction cost of the token’s specific chain.

Withdrawals from ULTRADE are instantaneous for all chains. Withdrawal gas costs are the typical transaction cost of the token’s specific chain.

Please note that instant withdrawal costs on Ethereum are high and can fluctuate drastically based on gas prices at time of withdrawal. We are working on an optional withdrawal solution that enables a delayed witdrawal at a much lower cost.
