Display raw build transactions human-readable

Staking & Delegation Operate a Stake Pool
1

Hey everyone, does anybody know if it is possible to “read” a raw-build transaction file?

Lets say I build a transaction (tx.raw) using the command-line-tool including inputs/outouts/certificates/etc. if i open the file I see a large hex-code which obviously is not human-readable. Any idea how I can make it human readable again?

Best

Maybe this will work, I didn’t use it but u can try

Cheers,

unforunately doesn’t work at least for my tx-file

Perhaps u need to adapt it

for example:

48 65 6c 6c 6f 2c 0d 0a 0d 0a 54 68 69 73 20 69 73 20 61 20 74 65 73 74 20 6d 65 73 73 61 67 65 21 0d 0a 0d 0a

Or if u can identify the transaction ID u can search for details on cardano block explorer

I just happen to come across a solution. Of course, the guys of iohk provide already a tool for it with cardano-cli. If you want to see the details of a previously build transaction tx.test:

cardano-cli transaction build-raw \
--allegra-era \
--tx-in c2642218ef9c5b2bc1ef66bf27c37640c0dfd159a0274c8100c852ca0b03d484#1\
--tx-out addr1qxergj4s957mq7nz6eqw9wn0xp7tqtemhqvkaq07dzlgk7qv88n9r72kflhm2gcfkgg7dadfd057u2nh8tkxjyse0z0q94fv3q+0\
--ttl 25000000 \
--fee 0 \
--out-file tx.test

You can use the command-line-interface to convert the tx-file to a cbor output.

cardano-cli text-view decode-cbor --in-file <tx.raw>

the output should look like this:

82  # list(2)
   a4  # map(4)
       # key
      00  # int(0)
       # value
      81  # list(1)
         82  # list(2)
            58 20 c2 64 22 18 ef 9c 5b 2b c1 ef 66 bf 27 c3 
            76 40 c0 df d1 59 a0 27 4c 81 00 c8 52 ca 0b 03 
            d4 84  # bytes(32)

            58 39 01 b2 34 4a b0 2d 3d b0 7a 62 d6 40 e2 ba

            e9 ee 2a 77 3a ec 69 12 19 78 9e  # bytes(57)
            00  # int(0)
       # key
      02  # int(2)
       # value
      00  # int(0)
       # key
      03  # int(3)
       # value
      1a 01 7d 78 40  # int(25000000)
   f6  # null

I found a website which can convert the trasaction back to json, cbor.me

which will give you again

[
   {0:
        [
            [h'C2642218EF9C5B2BC1EF66BF27C37640C0DFD159A0274C8100C852CA0B03D484', 
             1
            ]
        ], 
    1: [
           [h'01B2344AB02D3DB07A62D640E2BA6F307CB02F3BB8196E81FE68BE8B780C39E651F9564FEFB52309B211E6F5A96BE9EE2A773AEC691219789E',
            0
           ]
        ], 
    2: 0, 
    3: 25000000
    },
    null
]

If anybody has a better way please let me know. So far this is the only way I found.

Looking for the same thing. The text-view or json isn’t exactly human readable… You still have to known what each field means. I would love it if there’s some tool that add labels and formats this.

If you have eternl installed on chrome you could use the CIP30 api to have a preview:

await (await cardano.eternl.enable()).signTx('84a40081825820c8da3848010af1728d19555c9864dd4ace97ad56972b6bb352bbdc0f8ffb0d5200018282581d617a6a5ccbaf3e6308d8c09ccfa45b34cc7cccaa242dc2dc05ba2a72201a00d2eee782583901d07f6a9dc8cba4b368d04225c4cd36ce21b1800bc54e7924e65689d9ddbe7a587e6bdd2674bf53fc093226bbd43af035f4ea07d7811679661b000000037d3c3680021a0002b099031a047d9ea2a0f5f6', true)
