Interact with Subcoin Chain

The Polkadot-JS Apps is a versatile UI for engaging with a Substrate based node. You can connect to it to inspect the state of UTXO set, call RPCs, potentially transfer coins in the future.

To connect the Polkadot-JS Apps to your local node, open the sidebar and switch to Development > Local Node (127.0.0.1:9944).

Connect to Local Node

Inspect the State of UTXO Set​

Assuming the current best block is #125,954, you may want to examine the UTXO of the coinbase transaction for this block. The Bitcoin transaction ID for this coinbase transaction is 4ae4acf6fcdfec212de5fdcb7e58028764032aacaf194754b7e60fd842acd92f. You can view it here.

To look up the UTXO:

  1. Go to Developers > Chain State.
  2. Paste the txid into the H256 text box, note that 0x prefix is necessary.
  3. Click the + button on the right side to view the details of the coin.

Coin Storage

If the node you are connected to is an archive node, you will be able to inspect any UTXO at any height throughout the history.
