Isolation and limits
- The engine runs in a Web Worker; a request that takes more than 5 seconds is stopped.
- Each call has at most 5 000 000 fuel and 16 MiB of values, the same rules as language version 2 on the network.
- At most 32 contracts per session and 1 000 lines per scenario.
- Fees and storage deposits are estimates; real fees depend on the network's current parameters and congestion.
