Tokens and Swap

Adding a custom token

If you hold a token Keon does not show by default, you can add it by hand:

1. Open the Tokens tab.
2. Click Add Token.
3. Paste the token's contract address.

Keon looks up the name, symbol, and decimals from the chain. If it finds them, you get a preview before saving. If the contract is not a valid ERC-20, Keon will tell you and refuse to add it.

You cannot add the same token twice. Keon checks for duplicates before saving.

Verified vs. user-added tokens

Tokens fall into two groups:

• Verified tokens come from the TokenKit registry. They have logos, USD prices, and metadata pulled in automatically.
• User-added tokens (the ones you paste in by hand) start with no logo and no price. They show your balance and let you send them, but you will see a placeholder where the price would normally be.

If a token is missing from the verified list and you think it should be there, the token's project can submit it on tokenkithq.io.

Swapping tokens

Keon has a built-in swap that routes through the AVNU aggregator. AVNU compares quotes across every Starknet DEX so you get the best rate without doing the legwork.

1. Open the Swap tab.
2. Pick the token you want to spend (From) and the token you want to receive (To).
3. Type the amount. Keon fetches a quote and shows you the rate, the price impact, and the fee.
4. Adjust slippage if you need to. The default is fine for most swaps.
5. Hit Swap and review the simulated transaction.
6. Sign.

After a successful swap, both tokens refresh their balances automatically, and any new token from the swap is added to your wallet so you do not have to find it manually.

Why use the in-wallet swap

You could open a DEX in a browser tab and do the same swap there. The in-wallet version saves you a few steps:

• No need to connect a wallet, you are already in the wallet
• The aggregator picks the best route across Starknet DEXes for you
• You get the same simulation preview as a regular send, so you know what you will receive
• The output token is added to your wallet automatically

If a swap fails partway through (which is rare), Keon shows the revert reason from simulation so you know whether to bump slippage or try again later.
