A model picks, the math weights

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.

Go long on what you believe in.

Build an index in three taps and own it outright. It takes about a minute and one signature.
