Cardano

Addresses and keys only. A Shelley-era wallet phrase (Yoroi, Eternl, Lace, Daedalus Shelley; 12/15/24 BIP39 words) goes to key-to-addresses --chain ada: Icarus master key from the BIP39 entropy, CIP-1852 payment keys m/1852'/1815'/0'/0/0..4 and stake key m/1852'/1815'/0'/2/0, mainnet base addresses addr1q....

./blocktools run 'key-to-addresses --chain ada < /in/ada-mnemonic.txt'

private_key is the hex extended payment key (kL||kR), redacted by redact. NOT BUILT: Ledger / Trezor master-key derivations (different from Icarus for 24 words), Byron addresses (Ae2.../DdzFF...) and legacy Daedalus, spending passphrase, accounts > 0, change addresses. Look the addresses up on a block explorer, or use utxo-fetch below.

Transfers (payment / sweep)

utxo-fetch --chain ada addr1...SOURCE       # Koios: one line per UTxO with "utxo":"TXID#IX:LOVELACE"
acct-tx build --chain ada --from addr1...SOURCE --to addr1...DEST \
    --utxo TXID#IX:LOVELACE [--utxo ...] (--amount LOVELACE | --sweep) --fee 180000 --ttl SLOT > unsigned.json
acct-tx decode --chain ada < unsigned.json  # review
acct-tx sign --chain ada --tx unsigned.json --expect-to addr1...DEST > signed.json
# signed.json "signed" is hex CBOR (cardano-cli cborHex); submit it from a networked host.

The secret for sign is the 128-hex private_key from key-to-addresses (the row whose address is --from); sign refuses a key whose hash is not the from address's payment part. Change (inputs - amount - fee) goes back to --from; change between 0 and 1 ADA is refused. build refuses a fee below 44*size+155381 lovelace; TTL is an absolute slot (current tip slot + e.g. 7200). KAT: signed tx bytes == pycardano 0.19.2 for payment-with-change and sweep (abandon...about vector). Lookup tested live against Koios on an empty address only. NOT BUILT: UTxOs carrying native assets / tokens (utxo-fetch flags them; never pass them), multi-asset outputs, staking/delegation certificates, withdrawals, metadata, Byron inputs, protocol-parameter fetch (fee constants are hardcoded mainnet values), testnet.

Worked sweep (tested)

Unsigned sweep for abandon...about account 0, address 0 -> address 1, one 5 ADA UTxO. Inside ./blocktools run write the UTxO as TXID.IX:LOVELACE (the boundary refuses #), decoded through the agent boundary. Only public fields come back (from, to, amount, fee in base units, signed=false). Signing is the TTY step above (acct-tx sign ... --expect-to). It is a human-typed code, so recipe-check can't run it here; scripts/e2e.d/acct.sh drives it through a pty.
