## Simple Summary
9+
10+
Freeze wstETH on Plasma instance
11+
12+
## Motivation
13+
14+
Last week, Lido [announced](https://blog.lido.fi/announcing-partnership-with-chainlink-on-adopting-ccip-as-official-cross-chain-infrastructure-for-wsteth/) that Chainlink's CCIP will be the official cross-chain infrastructure for wstETH. While the wstETH representation on Plasma was already deployed through CCIP, it was unfortunately not set up in a fully future-proof manner.
15+
16+
Together with Chainlink, they have decided to redeploy the token contract to ensure the deployment is in line with the new cross-chain strategy. They ask us to deprecate the asset.
17+
18+
Right now, there is about 0.044 wstETH on Aave Plasma instance / 0.12 wstETH on Plasma.
19+
20+
## Specification
21+
22+
If passed, this AIP will freeze wstETH reserve on Plasma, preventing new deposits, borrows, or collateral enablement.
