Address

  • Powerful tool to convert SS58 account to sr25519::Pubkey: https://polkadot.subscan.io/tools/format_transform
  • Alice: from 5GrwvaEF5zXb26Fz9rcQpDWS57CtERHpNehXCPcNoHGKutQY to 0xd43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d
  • Bob: from 5FHneW46xGXgs5mUiveU4sbTyGBzmstUspZC92UhjJM694ty to 0x8eaf04151687736326c9fea17e25fc5287613693c912909cb226aa4794f26a48

Scenario

  1. Initially, Alice has a UTXO 1,125,899,906,842,624.
  2. She transfers to BOB a UTXO 842,624; but she doesn't have a UTXO $842,624. So she has to use her 1,125,899,906,842,624.
  3. TransactionInput contains outpoint is UTXO 1,125,899,906,842,624; sigscript is signed data of "simple transaction" (refer to runtime/src/utxo.rs:354).
  4. There will be 2 TransactionOutputs:
    • TransactionOutput contains value is UTXO 842,624; pubkey is Bob address
    • TransactionOutput contains value is UTXO 1,125,899,906,000,000; pubkey is Alice address

Steps

Check balance

  • Switch to Chain State, select utxo, utxoOf
  • Input: 0xd43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d
  • Press + button
  • Verify Alice has a UTXO hash
utxo.utxoOf: Option<H256>
0xc670c5f69081da78af400552edcafa3f0f31e84db1b50dd70776e0f87477b3dc
  • Then select utxo, utxoStore
  • Input: 0xc670c5f69081da78af400552edcafa3f0f31e84db1b50dd70776e0f87477b3dc
  • Press + button
  • Verify Alice has a UTXO value
utxo.utxoStore: Option<AcademyPowRuntimeUtxoTransactionOutput>
{
  value: 1,125,899,906,842,624
  pubkey: 0xd43593c715fdd31c61141abd04a99fd6822c8558854ccde39a5684e7a56da27d
}
