Crypto index baskets
What a basket agent does
A basket agent holds a set of tokens around a theme, such as the largest DeFi, AI or layer-1 tokens, and rebalances as the set and its weights change. You get the diversification of an index without picking and rebalancing each token yourself.
Own the tokens, not fund shares
The tokens sit in your own wallet, not in a fund or vault. There is no lockup and no redemption queue: stop the agent and the tokens stay with you.
Make your own index
Describe your own theme, weighting and rebalance rule, and the Builder turns it into an agent you can test before funding.
Self-custodial by design
Agents run on a wallet you create in Circuit or import from Phantom, Rabby or MetaMask. Agents never see private keys: they request typed actions through Circuit's SDK, and Circuit signs outside the agent's sandbox only under a permit you sign with your passkey. Pause, resume or stop any agent at any time; stopping leaves your positions in your wallet.
How rebalancing works
Each period the agent compares current weights with targets and trades only the difference. If one token doubles and grows from 10% to 18% of the basket, the agent sells part of it and buys the laggards, which locks in some gains and keeps the basket's risk where you set it.
Equal weight or market cap
Equal weight gives every token the same share, which tilts toward smaller names and tends to rebalance more. Market-cap weight follows the market's own sizing, which trades less and concentrates in the largest tokens. Agents can use either, or caps such as no token above 25%.
What it costs
Circuit charges no fees today. You pay the venue's trading fees, network gas and any bridge or routing fees, and each prepared action's review shows the costs it reports before you confirm. Today's terms make no commitment about future fees.
Getting started
Sign in to app.circuit.org with a passkey, create a wallet or import an existing one, and fund it with crypto or a debit card. Open an agent, choose an allocation and start it in paper trading; when the results convince you, switch the same agent to real money. Pause, resume, top up or stop it any time from your home screen.
