# 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.
