Algorand

Addresses and keys only, from Algorand's own 25-word mnemonic (Pera / algosdk format; the last word is a checksum). It is not a BIP39 seed, so derive does not cover it.

./blocktools run 'classify /in/algo-mnemonic.txt'


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

The key is printed as private_key = base64(seed || public key), the algosdk format, and is always redacted by redact.

Payments and sweep (acct-tx)

utxo-fetch --chain algo A...  # host-side: algonode: amount, min-balance, opted-in assets, last_round, min_fee
acct-tx build --chain algo --from A... --to A... --amount MICROALGO --fee 1000 --first-round LAST_ROUND > u.json
acct-tx build --chain algo --from A... --to A... --sweep --fee 1000 --first-round LAST_ROUND > u.json   # close-to
acct-tx decode --chain algo < u.json
acct-tx sign --chain algo --tx u.json --expect-to A... < key.txt > signed.json   # 25 words or base64 key; typed code on /dev/tty

Canonical msgpack pay only. The sweep is amount 0 with close-remainder-to = destination: everything moves and the account closes. Algorand refuses this while ASAs are opted in. Decode refuses rekey, lease, group, msig and lsig fields. --last-round defaults to first + 1000. KAT: unsigned and signed bytes and txids byte-equal to py-algorand-sdk (crates/acct/tests/kat.rs, scripts/e2e.d/acct.sh).

NOT BUILT: Ledger-style BIP32-Ed25519 paths (m/44'/283'/...), broadcast, ASA transfers, rekeyed accounts. UNTESTED: a real network submit; utxo-fetch was run once against mainnet-api.algonode.cloud (2026-10-25) and is not in CI.

Worked sweep (tested)

Unsigned sweep for the test-mnemonic account (close-to sweep: amount 0, everything to the close address), 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.
