Onchain ETFs: your questions, answered
What is an onchain ETF?
An onchain ETF is a single token backed in-kind by a basket of crypto assets held in a smart contract. Buy the token and you own the whole basket; sell it and you redeem the underlying. There's no fund manager and no custodian: the contract is the fund.
How do I buy an onchain ETF on Base?
Connect a Base wallet, pick a basket, and pay with USDC or ETH. Tessera routes your single deposit across the best of six DEXs and ERC-4626 vaults to assemble the basket, and you get one token that is the whole index.
Is Tessera custodial?
No. Tessera is permissionless, immutable and non-custodial. You always hold your own index tokens, and every basket is 100% backed in-kind by its underlying assets onchain.
What tokens can I put in a crypto index?
Any ERC-20 on Base: memecoins, majors, staking tokens (LSTs), or yield-bearing ERC-4626 vaults from Beefy, Yearn, Aave, Morpho and more. A basket can hold 2 to 30 assets with weights you choose.
Can I create my own index token?
Yes. Anyone can create an onchain ETF by choosing the tokens and weights and deploying. No code, no permission. You earn a share of the trading fees on every basket you create.
