new aldabra-core::mint module:
- PolicySpec enum: SingleSig, SingleSigTimelock, NofK
- SingleSig{pkh}: ScriptPubkey native script
- SingleSigTimelock{pkh, slot}: ScriptAll[ScriptPubkey, InvalidHereafter(slot)]
- NofK{n, [pkhs]}: ScriptNOfK
- PolicySpec::single_sig(payment) + single_sig_timelock(payment, slot)
convenience constructors that derive the pkh from a PaymentKey.
- policy_id() = pallas_traverse::ComputeHash<28>::compute_hash, which
is blake2b-224 of (0x00 || cbor) — the canonical native-script hash.
- to_cbor() for callers that want the script bytes raw.
build_signed_mint / build_unsigned_mint:
- two-pass fee like the send path, plus a few extras specific to mint:
staging.mint_asset(policy, name, qty), .script(Native, cbor),
.disclosed_signer(payment_pkh) — the disclosed_signer surfaces the
required signature in the tx body so the chain knows which witness
to verify against the script.
- positive qty mints (asset goes into dest output), negative qty burns
(asset comes out of input holdings, change preserves leftover).
- token-bearing change must hold ≥ min_utxo lovelace — same guard as
the send path.
mcp tools:
- wallet.policy.create — args: invalid_after_slot? — returns
{policy_id_hex, script_cbor_hex, type}.
- wallet.mint — args: dest_address, dest_lovelace (≥ 1 ADA),
asset_name_hex, quantity (i64), invalid_after_slot? — auto-generates
a single-sig policy bound to the wallet's payment key, builds, signs,
submits.
8 → 10 mcp tools. 48 → 56 unit tests.
3.2 (CIP-25 metadata) is BLOCKED on pallas-txbuilder 0.32/0.35 — both
hardcode `auxiliary_data: None` in the conway builder. options for next
session: (a) post-build CBOR injection, (b) assemble tx via
pallas-primitives directly, (c) wait for upstream. flagged in the
spec doc.
3.3 (CIP-68) depends on 3.2. 3.6 (MAP 2-of-2) needs the multi-key
signing flow on the build side; PolicySpec::NofK variant is ready but
build_signed_mint only sign with one key today.
end-to-end working wallet: paste 24-word mnemonic, age-encrypt at rest,
on unlock derive root + payment + stake keys, build cip-19 base address,
serve four tools over mcp stdio (wallet.address, wallet.network,
wallet.balance, wallet.utxos).
deps added: ed25519-bip32 0.4 (pallas only ships raw ed25519, not the
cardano variant of bip32 hd derivation), cryptoxide 0.4 for pbkdf2-hmac-sha512,
age 0.10 for at-rest mnemonic encryption, rpassword 7 for tty-only passphrase
prompts, toml 0.9 for config.toml.
new modules:
- crates/aldabra-core/src/derive.rs — payment + stake key derivation, hash
- crates/aldabra-chain/src/koios.rs — real reqwest impl, asset aggregation
- crates/aldabra-mcp/src/{bootstrap,config,tools}.rs
caught one bug pre-flight: get_balance was clobbering same-asset
quantities across utxos instead of summing. fixed + regression test.
headless support via ALDABRA_PASSPHRASE env (mcp clients own stdin so
the rpassword prompt path can't run). docker secret / systemd
EnvironmentFile sources it in production.
dockerfile: multi-stage rust:1.95-bookworm → debian:bookworm-slim, tini
as pid1, non-root aldabra user, /var/lib/aldabra owned 700.
29 unit tests + 1 ignored live-koios test. preprod smoke test exercised
initialize → tools/list → tools/call wallet.address end-to-end via
piped json-rpc; correct preprod address came back from canonical
abandon-art mnemonic.
phase 2 (send) is next.
