How exactly do we calculate metrics like TVL etc.?

It varies from project to project but we generally track the amount of tokens locked in all token bridges for a given L2. Sometimes it's a single token bridge like for zkSync but sometimes these are multiple token bridges for a single L2 (Optimism).

For details see our project definitions.
