How do you test in a multi-chain setup? 🤔 @_SEAL_Org uses parallel network forks for cross-chain emergency response drills. They simulate L1<>L2 message passing by triggering an event on L1 and relaying a tx on L2. Take a look at the setup & drop comments below 👇🧵

SEAL prepares protocols for cross-chain emergencies on parallel Virtual TestNets. The team forks production chains and simulates different scenarios: 🔹 ETH and ERC-20 token bridging 🔹 Oracle updates via an arbitrary messenger 🔹 Governance actions with L2 contract updates

We’d love to 👂 your thoughts: 👉 What do your cross-chain testing flows look like? 👉 How much time do you lose on setting up the infra? 👉 How do you ensure invariants are correct across chains, in a consistent way?
