  ThunderCore's sandbox is its public testnet — a full parallel EVM chain with
  its own gas token (TST), chain ID, RPC/WebSocket endpoints, block explorer,
  and faucet. Testnet tokens are separated from mainnet and should never have
  any value. Any Ethereum wallet address works on the testnet.

test_vs_live:
  separation: >-
    Mainnet (chain ID 108, TT gas token, https://mainnet-rpc.thundercore.com)
    and testnet (chain ID 18, TST gas token, https://testnet-rpc.thundercore.com)
    are entirely separate chains; switching is done by pointing the wallet or
    tooling at the other network's RPC and chain ID.
  notes: >-
    The docs recommend the testnet for developing applications without risking
    real assets, testing against new chain versions, and analyzing blockchain
    data on a smaller data set.
