Your own index.
One transaction.
Say what you want to own — “the picks and shovels of AI” — and Long builds a basket of tokenized stocks on Base and buys the whole thing in a single signature. Your keys, your shares.

From a sentence to a portfolio.
No tickers to hunt, no percentages to do by hand. You describe the exposure you want; Long turns it into a real basket you own.
Say it in plain words
Type what you believe in and what you don’t: the picks and shovels of AI, Mom’s favorites, AI without Nvidia.
A model picks, the math weights
It chooses the names from the live universe and sizes them by market cap, capped at 35% like the Nasdaq-100. Nudge any weight with a drag.
Buy it in one signature
Approve, every swap, and the fee settle as one atomic transaction. Gas is paid in USDC. The shares land in your wallet.


Not a slideshow. It settles on-chain.
Everything below already happened on Base mainnet, with a real wallet and real money. You can open every claim in a block explorer.
- One signature
- Approve, every swap and the fee batch atomically (EIP‑5792). If a single leg fails, nothing is spent.
- Zero custody
- The shares sit in your wallet, a Coinbase Smart Wallet opened with a passkey. Long never holds them.
- Gas in USDC
- A three-stock buy cost $0.016 of gas through Coinbase’s paymaster. No ETH to acquire or explain.
- Long’s fee
- A flat 0.5%, taken in the same batch. No spread, no custody fee, no lock-up.
- Proof
- A live three-stock buy: 0xb283…44e8 on Basescan.
Ten stocks today. The list keeps growing.
Every name is a tokenized stock issued by Coinbase, custodied by Alpaca and priced by Chainlink. Long treats the universe as data, not a constant, so new listings show up on their own.

Why this only works on Base
The stocks are here
Base is the one place Coinbase’s tokenized stocks exist with on-chain liquidity and official Chainlink price feeds. The pools are already deep — NVDAc/USDC alone holds about $2.2M.
Onboarding without the crypto tax
Smart Wallet plus a paymaster means a passkey to sign in and gas paid in USDC. No seed phrase to protect, no ETH to buy first.
Permissionless execution
Aerodrome already routes every trade and there was no one to ask. Long is an interface on open infrastructure, not a broker holding your money.
