# Migration

## Basethereum and the Leetswap Exploit

Basethereum was a seigniorage protocol inspired by Basis Cash and Tomb Finance. It was one of the first Defi projects to launch on Base Mainnet. The liquidity for its two tokens, Seigniorage Share ($SHARE) and Basethereum ($BETH) were on Leetswap.

However, due to a vurnurability in the Leetswap's router, SHARE/ETH and BETH/ETH LPs were drained resulting in a total of net $91,000 USD loss.

Holders of SHARE and BETH, as well as SHARE stakers and SHARE/ETH and BETH/ETH LPers will be compensated through a migratory claimdrop for $BASIN.

Pricing of SHARE and BETH as well as LPs is currently as follows:

<table><thead><tr><th width="144">Asset</th><th width="261">Last Market Price Per Token</th><th width="153">Migration Price</th><th>Grace Premium</th></tr></thead><tbody><tr><td>SHARE</td><td>$85</td><td>$100</td><td>+17.6%</td></tr><tr><td>BETH</td><td>$1185</td><td>$1400</td><td>+18.1%</td></tr><tr><td>SHARE/ETH</td><td>$256</td><td>$300</td><td>+17.1%</td></tr><tr><td>BETH/ETH</td><td>$3015</td><td>$3500</td><td>+16%</td></tr></tbody></table>

### Claiming $BASIN

* Affected addresses must have opened a ticket or posted their onchain information in the Discord's #migration channels
* $BASIN will be vested linearly for 2 weeks upon liquidity launch. This is to prevent instant dumpage.

## 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://basin-dao.gitbook.io/basinfinance/launch/migration.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.
