# How it works

**Step 1: Connect your wallet**\
Use the wallet you already trade with on **HyperEVM or Solana**. No new account, no extra onboarding, no KYC.

**Step 2: Approve Trickle**\
On HyperEVM, Trickle uses Permit2 for ERC-20 approvals. On Solana, it uses SPL delegate approval on eligible token accounts.

**Step 3: Set your destination**\
Choose where your savings should go and how they should be saved. Depending on the chain, that can mean Auto USDC, Auto HYPE or Auto SOL, or keeping the token in its native form.

**Step 4: Trade like usual**\
Keep swapping the assets you already trade. Trickle watches for eligible swaps and applies the same 1% savings logic in the background.

**Step 5: Savings arrive automatically**\
When an eligible swap happens, Trickle collects the savings slice, executes the selected savings flow, and sends the result to your configured savings wallet.

**Collection rules:**

| Swap        | What gets collected                                      |
| ----------- | -------------------------------------------------------- |
| BONK → WIF  | Nothing (neither HYPE nor USDC)                          |
| HYPE → BONK | 1% of HYPE sent                                          |
| BONK → HYPE | 1% of HYPE received                                      |
| USDC → WIF  | 1% of USDC sent                                          |
| WIF → USDC  | 1% of USDC received                                      |
| HYPE → USDC | 1% of HYPE only (tokenIn priority, no double collection) |

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter:

```
GET https://docs.usetrickle.xyz/the-protocol/how-it-works.md?ask=<question>&goal=<endgoal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
