How to swap crypto from your wallet

Guide · Using the swap

iCrypto has a swap built in, powered by the 0x DEX aggregator. It routes your trade across on-chain liquidity and executes it directly from your own wallet, signed by your own keys. There is no deposit to an exchange and no custody transfer: the tokens move from your wallet to the token you asked for, and back to your wallet, on the same chain. This guide covers the steps and the three costs that decide what you actually receive — the iCrypto fee, network gas, and slippage.

Before you swap

Your wallet holds the token you want to sell, on a supported chain.
You hold enough of the chain's native coin to pay gas — ETH on Ethereum, BNB on BNB Smart Chain, and so on.
Both tokens are on the same chain. The built-in swap exchanges tokens within a chain, not across chains.

Steps

Open the swap in your wallet. The swap runs on the 0x DEX aggregator and executes from your wallet, so you stay in custody the whole time.
Choose the pair and amount. Pick the token you are selling and the token you want, on the same chain, then enter the amount.
Review the quote. Check the rate, the estimated amount you will receive, the 0.25-0.35% iCrypto swap fee, the estimated network gas, and the slippage tolerance before going further.
Approve the token if prompted. Selling an ERC-20 or BEP-20 token may need a one-time approval transaction so the swap contract can move it. Swapping a native coin needs no approval.
Confirm and sign. Confirm the swap; it is signed with your keys and broadcast from your wallet. iCrypto never takes custody of your funds at any point.
Wait for settlement. Once the transaction confirms on-chain, the received token shows up in your wallet balance on that chain.

Understanding the costs

Three things sit between the headline rate and the amount that lands in your wallet. Read the quote with all three in mind.

Cost	Who charges it	What it is
iCrypto swap fee	iCrypto	A flat 0.25-0.35% of the swap, shown in the quote.
Network gas	The blockchain	The fee to include your transaction on-chain, paid in the chain's native coin. Varies with network demand.
Slippage	The market	The gap between the quoted price and the executed price if liquidity moves before your trade settles.

The 0.25-0.35% swap fee

iCrypto charges 0.25-0.35% on a swap. This is separate from, and on top of, the network gas fee. It is displayed in the quote before you sign, so you see the effect on your received amount in advance.

Network gas

Every on-chain swap pays gas to the network, in the chain's native coin. Gas is not set by iCrypto and rises and falls with network congestion. Keep enough of the native coin spare to cover it; a swap cannot settle if you cannot pay gas.

Slippage

Slippage is the difference between the price you were quoted and the price you actually get, caused by liquidity shifting between quote and settlement. A slippage tolerance sets the worst rate you will accept: too tight and a moving market can cause the swap to fail; too loose and you may receive noticeably less than quoted. On thin liquidity or large orders, expect more slippage and set the tolerance deliberately.

Tips for a clean swap

Always read the estimated received amount, not just the rate — it already reflects the 0.25-0.35% fee.
Hold a little extra native coin for gas so the transaction is not rejected mid-way.
On volatile pairs, a small trial swap tells you how the pair behaves before you commit a large amount.
If a quote looks far worse than expected, liquidity for that pair may be thin; reconsider the size or the pair.

FAQ

Who runs the swap?

The swap is built into iCrypto and powered by the 0x DEX aggregator, which sources on-chain liquidity. The trade executes directly from your wallet — iCrypto does not hold your funds.

What does it cost?

A 0.25-0.35% iCrypto swap fee, plus the network's gas fee. Slippage can also affect the amount received depending on market conditions.

Can I swap between two different chains?

The built-in swap exchanges tokens on the same chain. Choose both tokens on the chain you are trading.

Do I need to give up custody to swap?

No. The swap is signed by your keys and broadcast from your wallet. Your funds never pass through an iCrypto-held account.

Crypto assets are volatile and largely unregulated. You are solely responsible for your keys and funds. Nothing here is financial advice.
