summary: >-
  Meter runs a public testnet that mirrors mainnet for development. There is no
  API-key sandbox; the "sandbox" is the testnet chain reachable over the same
  Ethereum-RPC and native-RESTful/WebSocket interfaces as mainnet.
test_vs_live:
  model: separate-network
  detail: Testnet and mainnet are distinct chains with distinct endpoints (below).
endpoints:
  testnet:
    ethereum_rpc: https://rpctest.meter.io
    ethereum_ws: wss://wstest.meter.io
    native_restful: https://testnet.meter.io
    the_graph: http://graphtest.meter.io:8020/
  mainnet:
    ethereum_rpc: https://rpc.meter.io
    ethereum_ws: wss://ws.meter.io
    native_restful: https://mainnet.meter.io
    the_graph: http://graph.meter.io:8020/
test_gas:
  detail: >-
    Testnet gas (test MTR) is obtained from the Meter testnet faucet / community
    Discord rather than purchased. No test card / hosted-token model applies (this is
    an L1 blockchain, not a payments API).
notes: >-
  No secret sandbox credentials to capture — the interfaces are public and
  unauthenticated. Contract-verification tooling (Sourcify) and IDEs (Remix, Hardhat)
  can point at the testnet RPC for a full test loop.
