Withdrawing Tokens From rhino.fi.

You have three options to withdraw your tokens from rhino.fi:

Regular withdrawals to the Ethereum mainnet (a two-step process where you pay & control the gas fee at the end of the process from your on-chain wallet).
Fast withdrawals to the Ethereum mainnet.
Fast withdrawals to the Polygon network .

Scroll down this article for more details about each withdrawal option.



Withdrawals will default to the fast withdrawals on Ethereum if fast withdrawals are eligible for that token. You can change from fast to regular by clicking on the 'Advanced' link in the withdrawal widget.

Option 1 - Regular Withdrawals Ethereum

Regular withdrawals are available for all tokens on rhino.fi. This requires a two-step process.

1) Initiate the withdrawal and then wait 8-17 hours.
2) Make the final on-chain transaction to send the tokens back to your Ethereum mainnet wallet.

Pending - Until your withdrawal is ready for you to send back to your on-chain/Layer-1 wallet, the withdrawal will display as 'Pending' in your Portfolio section.

Ready To send - When your withdrawal is ready to send back to your on-chain wallet, you will see a popup notification on the Portfolio screen.

Cancel - You can cancel the withdrawal in the Portfolio section until the point where it has been processed and is ready to send back to your on-chain wallet.

Fee - There is no fee charged by rhino.fi, but you pay the ETH gas at the end of the withdrawal process (when you make the final TX to send back to your Layer-1 wallet).

Tip - always make sure that you have at least 0.02 ETH in your on-chain wallet, otherwise MetaMask may quote you an erroneously high gas fee or give you an 'out of gas error' even though the final cost of the transaction will likely be much lower (depending on global gas prices).

Option 2 - Fast Withdrawals Ethereum

Fast withdrawals are available for a subset of tokens on rhino.fi and tokens arrive in your on-chain wallet almost instantly.

There is a limited pool of tokens available for fast withdrawals at any one time, and this pool is frequently replenished.

The fast withdrawal tokens supported at this time are as follows:

USDt
ETH
wBTC
USDc
AAVE
DVF
LDO
ERP

Fee - rhino.fi pays the gas on your behalf and a fee is taken from your rhino.fi account in the native token that you are withdrawing.

Option 3 - Fast Withdrawals Polygon Network

You can withdraw a subset of tokens to the Polygon network from rhino.fi.



You pay a $1 fee in the currency that you are withdrawing, taken from your rhino.fi account.

Fast withdrawal tokens supported at this time are as follows:
USDt
USDC
DAI
MATIC
ERP

You can view the maximum amount of tokens available for withdrawal via the bridge by checking the bridge token balances here.

Tip Some Polygon wallets may not automatically display the token even though the tokens are safely in your Polygon address. You can check the tokens that are in your Polygon address by pasting your Polygon/Ethereum address into the Polygonscan explorer.

Background
rhino.fi uses a type of cryptography called STARKs to prove and verify trading activity on our exchange in a trustless manner. This means that trading on rhino.fi is self-custodial; rhino.fi cannot take possession of customer funds and in the unlikely event that the exchange were to go offline, traders can activate an ‘escape hatch’ via the Data Availability Committee to retrieve their funds.

Trades are signed and submitted off-chain, allowing traders’ off-chain balances to be updated instantaneously after each trade. When enough time has passed, a proof of the new rhino.fi state balance is submitted for settlement on the Ethereum blockchain and is verified by the Data Availability Committee, as well as the StarkWare smart contract.

This batching process has some distinct advantages. As trading activity is not limited to the underlying Ethereum blockchain capacity, rhino.fi can trustlessly process over 9,000 trades per second whilst at the same time passing gas savings onto traders in the form of lower trading fees. Trading fees on rhino.fi range from 0% to 0.2%, and rhino.fi traders pay no gas for placing, executing or cancelling orders. This is in contrast to on-chain self-custodial exchanges, where fees range from 0.3% to 0.5% and traders are forced to pay gas costs in order to execute trades.
