I am currently working to build a private network from Byron to Alonzo and I think I have some test-ada left in a Byron address.
If I am in the Shelley (Alonzo) era and I am using the cli to conduct transactions, are there:
1) CLI commands to look at the UTXO's at a Byron era address?
2) CLI commands to move ada from the Byron era address to the Shelley era address?
Please let me know if you need any clarification on the questions. Thank You.

As Byron does not change address types, we will be still referring to them as Shelley type addresses.
- To look at your UTXOs, using
cardano-cli
:
cardano-cli query utxo \
--address $(cat payment.addr) \
--mainnet
TxHash TxIx Amount
----------------------------------------------------------------------------------------
4e3a6e7fdcb0d0efa17bf79c13aed2b4cb9baf37fb1aa2e39553d5bd720c5c99 4 20000000 lovelace
- This is more complicated, but it is well documented in the
cardano-cli
documentation, as follows:
Create a draft for the transaction and save it in tx.draft
Note that for --tx-in
we use the following syntax: TxHash#TxIx
where TxHash
is the transaction hash and TxIx
is the index; for --tx-out
we use: TxOut+Lovelace
where TxOut
is the hex encoded address followed by the amount in Lovelace
. For the transaction draft --tx-out, --invalid-hereafter and --fee can be set to zero.
cardano-cli transaction build-raw \
--tx-in 4e3a6e7fdcb0d0efa17bf79c13aed2b4cb9baf37fb1aa2e39553d5bd720c5c99#4 \
--tx-out $(cat payment2.addr)+0 \
--tx-out $(cat payment.addr)+0 \
--invalid-hereafter 0 \
--fee 0 \
--out-file tx.draft
Calculate the fee
A simple transaction needs one input, a valid UTXO from payment.addr
, and two outputs:
- Output1: The address that receives the transaction.
- Output2: The address that receives the change of the transaction.
Note that to calculate the fee you need to include the draft transaction
cardano-cli transaction calculate-min-fee \
--tx-body-file tx.draft \
--tx-in-count 1 \
--tx-out-count 2 \
--witness-count 1 \
--byron-witness-count 0 \
--mainnet \
--protocol-params-file protocol.json
> 167965
Calculate the change to send back to payment.addr,
all amounts must be in Lovelace:
expr <UTXO BALANCE> - <AMOUNT TO SEND> - <TRANSACTION FEE>
For example, if we send 10 ADA from a UTxO containing 20 ADA, the change to send back to payment.addr
after paying the fee is: 9.832035 ADA
expr 20000000 - 10000000 - 167965
> 9832035
Determine the TTL (time to Live) for the transaction
To build the transaction we need to specify the TTL (Time to live), this is the slot height limit for our transaction to be included in a block, if it is not in a block by that slot the transaction will be cancelled. So TTL = slot + N slots. Where N is the amount of slots you want to add to give the transaction a window to be included in a block.
Query the tip of the blockchain:
cardano-cli query tip --mainnet
Look for the value of slot
{
"epoch": 259,
"hash": "dbf5104ab91a7a0b405353ad31760b52b2703098ec17185bdd7ff1800bb61aca",
"slot": 26633911,
"block": 5580350
}
Calculate your invalid-hereafter
, for example: 26633911 + 200 slots = 26634111
Build the transaction
We write the transaction in a file, we will name it tx.raw
.
cardano-cli transaction build-raw \
--tx-in 4e3a6e7fdcb0d0efa17bf79c13aed2b4cb9baf37fb1aa2e39553d5bd720c5c99#4 \
--tx-out $(cat payment2.addr)+10000000 \
--tx-out $(cat payment.addr)+9832035 \
--invalid-hereafter 26634111 \
--fee 167965 \
--out-file tx.raw
Sign the transaction
Sign the transaction with the signing key payment.skey and save the signed transaction in tx.signed
cardano-cli transaction sign \
--tx-body-file tx.raw \
--signing-key-file payment.skey \
--mainnet \
--out-file tx.signed
Submit the transaction
cardano-cli transaction submit \
--tx-file tx.signed \
--mainnet
