# Quickstart

Open Hexkit and complete your first task — no install, no account.

Hexkit runs in your browser at
[web3-toolkit.vercel.app](https://web3-toolkit.vercel.app). There is nothing to
install and no account to create. Open it and you can start decoding calldata
immediately; connect a wallet only when you want to sign something.

## Your first minute

#### Open the app

    Go to [web3-toolkit.vercel.app](https://web3-toolkit.vercel.app). The command
    bar at the top accepts an address, a transaction hash, a 4-byte selector, or a
    page name — press <kbd>⌘K</kbd> (or <kbd>Ctrl</kbd>+<kbd>K</kbd>) to focus it
    from anywhere.

#### Choose your RPC, or skip it

    On first load Hexkit asks whether to use your own RPC provider or the built-in
    public endpoints. Public defaults work fine for reading and decoding; they are
    shared, so they can be rate-limited under load. You can change this later.

#### Decode a transaction

    Paste any mainnet transaction hash into the command bar. Hexkit resolves the
    function selector against its signature database and shows the decoded
    parameters with their types and values — no ABI required, and no wallet
    connection.

#### Simulate before you sign

    From a decoded transaction, run a simulation to see the asset changes it would
    produce — which tokens move, in what direction, and by how much — before it
    ever reaches your wallet.

> **Tip:**
  Everything above works without connecting a wallet. Connect one only for actions
  that need a signature, like depositing into a vault.

## Browse yield vaults

Open **Integrations → LI.FI Earn** to browse vaults across 20+ protocols. Filter by
chain, protocol, or tag, and sort by APY, TVL, or name.

You do not need to connect a wallet to look. Paste any address into the
**Paste address…** field and Hexkit will show that address's positions — useful for
inspecting a wallet you do not control.

### Read the risk signals first

Vaults carrying risk signals are marked **Caution**. Opening one shows exactly which
signals fired before you go any further.

`Micro TVL` means very little capital is deposited. `Reward-heavy` means most of the
headline APY comes from incentive rewards rather than the vault's base yield, so it
can fall sharply when the incentives end. Neither is automatically disqualifying —
they are things to check rather than warnings to dismiss.

### Look past the headline APY

Expanding a vault shows its APY over 1, 7, and 30 days alongside a trend line, its
TVL, and the underlying contract address.

A vault advertising 138% today but 105% across the last 30 days is telling you
something the headline number is not.

## Deposit into a vault

Connect your wallet, pick a vault, and enter an amount. If your funds are on a
different chain from the vault, Hexkit handles the cross-chain path for you — see
[Deposit into a vault](/guides/deposits) for the full walkthrough.

## Where to go next
