I hacked on Rebaseable with @lajos In <36 hours, we built the first bridge for rebasing tokens. We leveraged Scroll's L1SLOAD precompile, EIP-4788, and LayerZero's OFT & lzRead to preserve & publish rebase events. We also played around with Gnosis Pay Safe's + mini-apps powered by World! ethglobal.com/showcase/rebaseable-82yy6

I watched the video. Is the advantage of this that mainnet and the layer 2 L2 are interacting with the liquid staking token directly rather than the user needing to trust a bridge that can be hacked for the assets held on the bridge? If there is no bridge does the liquid staking contract, Rocket Pool for example, burn the rETH on mainnet when it is moved to a layer 2 like Scroll, and Scroll remints it?

The problem is that when try to use a normal bridge to transfer a rebasing token (e.g. stETH) from L1 -> L2, the balance will update on the L1 but it won't update on the designated L2. So our solution is still a bridge, but we leverage some tools to get the yield update and mint the tokens to everyone on-chain.

Also all tech posts need a Rick and Morty meme to be taken seriously!

This is extremely useful when someone wants to deposit a liquid staking token on an L2! Similar to how EigenLayer is increasing the use of natively staked ETH for other apps and L2s.
