In this workshop we will explore some interesting new use cases unlocked by the newly proposed L1SLOAD precompile (RIP-7728). We will develop and deploy L2 dapps that read from L1 state using this precompile.

L1SLOAD in Action: Write L2 Dapps that Read from L1 State

We recently introduced [RIP 7728: L1SLOAD Precompile](https://github.com/ethereum/RIPs/pull/27). This is a new L2 precompile that allows dapps on L2s to read from the L1 state.

In this talk, we will explain how L1SLOAD works, and we will highlight some of the most exciting use cases that this precompile will unlock.
