How to make a first Ethereum trade on fermi swap

To make a first Ethereum trade on fermi swap, connect an Ethereum wallet, choose a token pair and review the quote before approving or sending a transaction. FermiSwap is listed by DefiLlama as an Ethereum proprietary automated market maker, or AMM, which fills trades from its own token inventory.

What do I need before using fermi swap?

You need a wallet with the token you plan to trade and ETH to pay Ethereum network fees. Pick a small amount for a first transaction, and check that the wallet is set to Ethereum mainnet; a token held on another network will not automatically be available to trade.

Open fermi swap and check that the page identifies Ethereum before connecting your wallet. Choose the token to sell and the token to receive, then enter the amount; the displayed output is an estimate, and the final amount can change before execution.

How does a first swap work?

FermiSwap’s inventory model differs from a pool AMM: DefiLlama says the protocol holds tokens in inventory vaults and counts volume when it fills a swap. For a user, the practical steps remain familiar, but the quoted output and whether the trade can be filled depend on the available inventory and the size of the order.

• Check the token names and, where shown, their contract addresses.
• Review the estimated amount out and any price impact or slippage setting.
• If the wallet requests token approval, approve only the token and amount needed for the trade.
• Review the swap transaction details and Ethereum gas fee before confirming.

A token approval lets a contract spend a specified token amount from your wallet; it is separate from the swap itself. Confirm the trade only after checking the recipient token, minimum output and network fee in the wallet prompt.

What should I check after sending the trade?

Wait for the wallet to show the transaction as confirmed, then check its activity and token balances. A pending transaction has not finished, and a failed transaction can still consume gas. If the quote changes beyond the permitted slippage, the swap may revert rather than deliver less than its stated minimum.

For a first fermi swap trade, the clearest approach is to use a modest amount, inspect the quote and approve only what the wallet prompt requires. The transaction status and resulting balance will show whether the swap completed; future trades still require a fresh quote and fee check.
