Tips and Tricks to Deploy L1 Smart Contracts on Optimism

on YouTube ↗16m

" summary

Builds a working Synthetics dApp on Optimism (see Quentin.oh) by reusing existing Solidity code compiled with an OVM transpiler (Solc fork), connecting L1 escrow + bridge to an L2 sequencer and relayer, and handling deposits/mints and withdrawals with a one-week withdrawal delay. Tests include unit tests, L1 integration, L2 integration (Optimism Docker sequencer/geth fork) and full cross-layer deposit/withdraw flows. Notes: contract-size bloat from transpiler, L2 sees L1 block timestamps, and gas encoding yields values like gas price 0.015.
