The nodes currently running in the PoA testnet can be seen at the Polkadot telemetry. For the nodes in PoA mainnet, see telemetry here.

Our fork of Polkadot-js apps showing block explorer and other tools is here. You can notice the validators producing blocks in a round-robin fashion in the explorer. Some things to keep in mind:

  • To query the balance of an account, use the system module and not the balances module.

  • The decimal places and token symbol are not part of the testnet chain spec and that makes the transaction fees event (TxnFeesGiven) show a fees of 0. This will be fixed in the mainnet but for the time being SDK can be used to query the events with correct values.
