Create an index

Pick tokens, set weights, put ETH behind it. Or paste a wallet address and start from what it holds.

Creating an index takes a few minutes and one transaction. You need a wallet connected to Robinhood Chain with at least 0.003 ETH in it, plus a little extra for the network fee.

Step by step

  1. Open Create. You can start with an empty basket or, further down this page, from a wallet address.

  2. Choose the tokens. Search by name or ticker. Only tokens with a Uniswap V2 or V3 pool with WETH or USDG can go in, because the vault has to be able to buy and sell them. Pick between 2 and 20.

  3. Set the weights. Each token gets a share of the whole; the shares must add up to everything, and none may be above 50%. The page shows a live preview of the basket and its risk score as you adjust. See Risk score for what the number means.

  4. Name and describe it. A name, a ticker, and a sentence or two about the idea. You can add a picture; square works best. All of this can be edited later from the index page, by signing a message with the same wallet.

  5. Put ETH behind it. At least 0.003 ETH. 90% of the deposit buys the basket in your weights and becomes the vault's first holdings; 10% buys $FRACTIONS and burns it. The deposit is not refundable as a deposit: it is your first position, bought at the launch price of 0.000001 ETH per index token, and you can sell it like any other position.

  6. Review and confirm. The review step lists every token, every weight, the deposit and what it buys. Confirm in your wallet. When the transaction lands, the index has a page at /i/<id>, a share card, and is listed on the home page.

Start from a wallet

Any Robinhood Chain address can become an index draft: yours, a friend's, or one you admire. The app reads what that wallet holds and turns it into a basket.

  1. Paste an address into the "Start from a wallet" box on the Create page, or open the link /create?wallet=0x… with the address filled in.

  2. The app keeps the eligible tokens. Tokens without a Uniswap V2 or V3 pool with WETH or USDG are left out, and so are holdings too small to price. What remains is weighted by value, the way the wallet is, with no token above 50%; anything over the cap is spread across the rest in proportion. At most 20 tokens make it in.

  3. A name is suggested. The draft is called "<short address> mirror", with the address shortened to its first and last characters. Rename it after whoever the wallet belongs to, or whatever the idea is.

  4. Adjust, then continue as above: describe it, put ETH behind it, review, confirm. The weights are a starting point; you can change any of them before you confirm.

The finished index page notes that it mirrors wallet 0x…, so buyers know where the recipe came from. It is still a fixed recipe: if the wallet later changes what it holds, the index does not follow.

After it is live

  • Your index page is /i/<id>. It has the chart, the composition with weights, the buy and sell panel, the creator and the share panel.
  • You earn 1% of every buy and 0.5% of every sell, in ETH, claimable any time from Portfolio. See Fees.
  • Your creator page at /u/<handle> lists every index you have made. See Creator profiles and badges.
