Our verdict on vfat.io
7.8/10vfat.io is a capable tool for experienced DeFi users who farm across several chains and want to compound, rebalance and track positions without repeating manual steps. Its main strengths are the Sickle smart wallet, which keeps self-custody, and unusually broad chain and protocol coverage. The main caveat is that fees are not published publicly and farming risk still applies, so check the docs, audits and transaction previews and start small.

What is vfat.io?
vfat.io is a multi-chain yield aggregator and portfolio manager. DefiLlama describes it as underpinned by Sickle, a smart contract wallet for yield farming that reduces complex operations such as entering or exiting positions, compounding and rebalancing to single transactions, while maintaining self-custody.
DefiLlama lists it since May 2024 with roughly 32.5 million dollars in TVL, down about 2.9 percent over seven days, and support across a long list of chains including Ethereum, Base, Arbitrum, Hyperliquid and Monad. It lists two audits and no native token.
Beyond farming, the homepage shows a portfolio tracker, a swap and bridge tool, token and lending data pages, a Telegram bot and an MCP server that connects it to AI clients. It also carries a link to the older vfat.tools site as part of its ecosystem.
How vfat.io works
vfat.io sits on top of existing DeFi protocols such as DEX liquidity pools and lending markets. Instead of approving, swapping, depositing, staking and claiming rewards in separate steps, a user acts through Sickle, a smart contract wallet that packages those steps into one transaction.
Because the wallet is described as non-custodial, the user stays in control of the assets. Automations can then handle recurring tasks such as compounding rewards or rebalancing a position, so the user does not have to repeat each step by hand.
The app also includes a portfolio tracker, a swap and bridge tool that draws on several DEX aggregators, and data pages for tokens, lending and protocol stats.

Pros and cons
What we like
- Non-custodial design: the stated goal is automation while the user keeps control of their assets.
- Single-transaction flows for entering, exiting, compounding and rebalancing reduce manual steps.
- Very wide chain coverage, with nearly 40 networks listed on DefiLlama.
- Two audits are listed and an audits page is linked in the docs.
- Includes a multi-wallet portfolio tracker, swap and bridge aggregation and research pages in one app.
- No native token, so no token needed to use the product.
Watch out for
- No native token and no published fee schedule, so users cannot see the cost of automation up front.
- Smart contract wallet design (Sickle) adds a contract layer on top of the underlying farms, so users take on risk from both.
- Support for nearly 40 chains means uneven liquidity and protocol maturity; some listed networks are young.
- Audit details are only referenced, not described publicly, so scope and findings need to be checked in the docs.
- Yield farming itself carries impermanent loss, reward-token volatility and liquidation risk on lending positions.
- The interface assumes familiarity with DeFi terms such as LP positions, compounding and rebalancing.
vfat.io fees
The project does not publish a fee schedule for vfat.io. DefiLlama lists no token, and its homepage does not state performance or management fees.
Users would normally see the costs in the transaction preview inside the app and in the documentation. Network gas fees and swap or bridge route costs also apply, and they vary by chain.
Is vfat.io safe?
DefiLlama lists two audits, and the homepage labels the product non-custodial and audited, linking to an audit page in its docs. The project does not describe the auditors, scope or findings, so readers should open the reports themselves. No hack or incident appears.
Risk remains at several levels: the Sickle smart contract wallet, the underlying DEXs and lending protocols, bridges and swap routes, and the volatility of farmed assets. Impermanent loss and liquidation are real possibilities. Start small, and check that the interface and contract addresses are the official ones before signing anything.

Who vfat.io is for
vfat.io is for intermediate to advanced DeFi users who already hold assets or LP positions on several chains and want one place to find yield, automate upkeep and monitor a portfolio. Newcomers can use it, but should first learn how liquidity pools, impermanent loss and gas fees work.
