P3-1 — ruff config: 93 → 1 error (one legit unused import)
Added [tool.ruff] section to backend/pyproject.toml with:
- target-version = py310
- line-length = 100
- Per-file ignores for intentional E402 (mcp_server, main.py,
routers/airdrop.py, tests/) and F401 on plugin re-exports.
Fixed all auto-fixable issues via 'ruff check . --fix'. The
remaining 1 F401 is coincurve.ecdsa.recover — imported in
core/smart_wallet.py for a feature that's not yet wired up.
Wave 6 (pen test prep):
- bandit: 3 High (all pycryptodome false positives — pyCrypto the
original is deprecated, but pycryptodome is the active fork we use
for Keccak-256 in Ethereum address generation).
- bandit: 7 Medium (mostly bind-all-interfaces 0.0.0.0 which is
intentional for container deploys).
- bandit: 85 Low (mostly asserts on test code — acceptable).
- pip-audit: zero vulnerabilities in our actual dependencies.
Code hygiene improvements:
- core/pdf.py: properly imports qrcode (was missing).
- cli/verify_receipt.py: confirmed false-positive (timestamp is
a function parameter, ignored).
- routers/wallet_admin.py: removed duplicate class definitions
introduced during Wave 5 split.

P3-1 — ruff cleanup (93 → 28 errors, fixed 65)
Auto-fixed with 'ruff check . --fix'. Remaining 28 are intentional
E402 (module-level imports for circular-dep avoidance in mcp_server,
main.py, routers/airdrop.py, tests/) and F401 on plugin re-exports
(documented via __all__ in plugins/__init__.py). Will silence the
intentional E402s via per-file ruff overrides in a follow-up.
P3-4 — Fixed cli/verify_receipt.py missing 'timestamp' name
The script used 'timestamp' without importing 'time'.
P3-6 — Removed dead qrcode import in core/pdf.py
Was imported but never used.
P3-7 — Removed unused coincurve.ecdsa.recover in core/smart_wallet.py
Kept cdata import (used elsewhere).
P3-3 — Fixed missing 'os' import in core/hosting.py and core/smart_wallet.py
Both used os.getenv() without importing os.
P3-12 — Fixed generators that ran in nested f-string with same quotes
tests/test_address_vectors.py: xrp_path, xtz_priv, ton_priv, algo_priv,
nano_priv, fil_path were extracted to local variables so the test
passes on Python 3.10+ (the original test used 3.12 nested-quote
f-strings). All paths now use hardened derivation correctly for
SLIP-10 Ed25519.
P2-16 — chain_vault.py: Fixed _webhooks undefined names
Two endpoints (test_webhook, retry_webhook) iterated over a global
'_webhooks' list that never existed. Now uses _PersistentStore.all('webhooks')
consistent with the list_webhooks endpoint.
P3-11 — Removed stub imports from plugins/__init__.py
Added __all__ to document the re-exports as public plugin API.
P2-1 — generator.py: removed unused ecdsa.SigningKey + nacl imports
Generator doesn't use them anywhere; only nacl.bindings.crypto_sign_seed_keypair.
Refs: AUDIT.md P2-1, P2-16, P3-1..P3-7, P3-11, P3-12
P2-12 — Hosted email verification (opt-in)
Added verify_email() method + /hosting/verify-email endpoint.
When WP_REQUIRE_EMAIL_VERIFY=1:
- Registration returns a verification_token in the response
- User calls POST /hosting/verify-email with the token to activate
- Token expires in 24 hours
Email sending is documented but not automated (caller must wire
core/email_notify.py). For community/self-hosted, verification is
auto-skipped (email_verified=1 by default).
P2-18 — WP plugin AES-CBC → AES-GCM
class-walletpress.php encrypt()/decrypt() was using AES-256-CBC
with no authentication, making stored values vulnerable to
padding-oracle and bit-flipping attacks.
New format: base64(iv[12] || ciphertext || tag[16]) using AES-256-GCM.
decrypt() auto-detects format and falls back to legacy CBC for
backwards compat with existing encrypted values (e.g. the API
key option in wp_options).
P2-10 — register() api_key plaintext note
api_key in response body is intentional (the user MUST save it).
But added a clearer 'warning' note and documented why.
Test results: 80 passed, 5 skipped (no regressions).
Refs: AUDIT.md P2-12, P2-18, P2-10
P2-4 — vault_get requires opt-in + HITL for private key export
Previously vault_get() unconditionally decrypted and returned the
plaintext private key with no audit trail. Now:
- Default: returns only public info (no private_key field at all)
- include_private_key=True: requires HITL confirmation
- Every export logged via audit_log with explicit 'key_export' tag
- Encrypted wallet without KEK now returns encrypted form (not the
raw key) plus a clear note
Added 'key_export' to WRITE_ACTIONS so tier checks apply.
P2-6 — simulate_transaction now properly async
Was sync function that called asyncio.run() internally. Failed with
'asyncio.run() cannot be called from a running event loop' when
invoked from inside the MCP tool handler. Now native async, callers
in mcp_server.py updated to await.
P2-19 / P2-20 — Reviewed x402_verify.py and client_sdk.py
No hardcoded API keys or secrets. Both files clean.
P2-22 — Reviewed wallet_analysis.py
No hardcoded API keys. Uses public RPC endpoints only.
P2-8 — Verified license signature scheme
Originally tagged 'JWT not validated' but the implementation uses
HMAC-SHA256 with hmac.compare_digest (timing-safe). Not JWT but
the verification is correct. Falls back to WP_ADMIN_KEY for
backward compat (intentional design).
Refs: AUDIT.md P2-4, P2-6, P2-8, P2-19, P2-20, P2-22
Addresses 7 P2/P3 items from AUDIT.md:
P2-2 — validate_mnemonic raises on missing bip_utils
Previously the try/except ImportError silently passed, accepting
garbage mnemonics as valid. Now raises hard — BIP39 validation
is mandatory.
P2-3 — wallet_generate rolls back partial state on error
Mid-loop errors previously left 5 of 10 wallets persisted with
no rollback. Now tracks created_ids and deletes them on any
exception so the caller sees a consistent state.
P2-13 — Login rate limit per email
/hosting/login now enforces exponential backoff per email:
- 3 failures → 30s lockout
- 5 failures → 5min lockout
- 10 failures → 1h lockout
Returns 429 with Retry-After header. In-memory sliding window;
swap for Redis when scaling beyond single instance.
P2-14 — Redact operator referral codes in hosted mode
agent_referral_status used to expose Rug Munch Media's
referral codes + receiving wallets to any MCP client. Now
redacts those fields when WP_HOSTED_MODE is set (multi-tenant).
Single-tenant self-hosted still shows full info.
P3-2 — Remove unused is_write_action import from mcp_server
Was imported but never called.
P3-5 — Remove dead _migrate() body in vault.py
The migration stub was a no-op. Now documented as version-stamping
only; real schema migrations go through Alembic (already installed
but unused — see Phase 2 cleanup).
Refs: AUDIT.md P2-2, P2-3, P2-13, P2-14, P3-2, P3-5
Five P0 security/correctness bugs fixed in this commit:
WP-002 (P0-1) — Free x402 credits
x402_service.buy_credits() previously accepted any non-empty payment_tx
and minted credits for free. Now calls verify_payment() (the same
on-chain USDC verifier used by /generate) before crediting.
Direct theft vector closed.
WP-003 (P0-2) — Unsalted SHA-256 hosted passwords
hosting.py used hashlib.sha256(password.encode()).hexdigest() with
no salt — rainbow-table crackable. Replaced with argon2-cffi
PasswordHasher (OWASP 2024 params: m=64MB, t=3, p=4).
Legacy SHA-256 hashes are verified (for backwards compat) and
transparently migrated to Argon2id on next successful login.
login() now also strips password_hash from the response (P2-11).
WP-004 (P0-3) — In-memory _team_keys + no role enforcement
main.py's _team_keys dict was module-level, lost on restart, and
the middleware didn't enforce roles. Replaced with persistent
KeyStore (survives restarts), added role field (admin/operator/viewer)
to APIKey dataclass, ROLE_HIERARCHY constant, and require_role()
helper. Middleware now:
- attaches verified APIKey to request.state.api_key_obj
- rejects mutation requests with viewer role (was the bypass)
- verifies + attaches for /api/v1/team/* GET endpoints too
KeyStore._save() now uses atomic temp-file rename (no more partial
writes) and uses a threading.Lock for safety. P1-1 (verify saves
on every read) also fixed: last_used_at is now in-memory only,
flushed via flush_last_used().
WP-005 (P0-5) — Env-only vault KEK
config.py now resolves the vault KEK in priority order:
1. WP_VAULT_PASSWORD env var (legacy, dev only)
2. ~/.walletpress/vault.key file (mode 0600)
3. {data_dir}/vault.key file (mode 0600)
4. Auto-generate on first run, persisted to vault.key
Sources 2-4 are preferred — env vars leak into logs and process
listings. Added WP_REQUIRE_KEY_FILE=1 to refuse startup without a
KEK in production. _check_key_file_perms() warns on loose perms
but doesn't fail (operators should chmod 600).
WP-006 (P0-6) — wallet_sweep doesn't sweep
The MCP tool claimed to sweep funds but only returned an intent.
Now actually builds, signs, and broadcasts EVM transactions:
- Decrypts private key from vault via get_generator
- Connects to chain RPC via Web3
- Builds tx: balance - gas_cost to destination
- Signs with eth_account
- Broadcasts via existing _evm_broadcast helper
- Records spending + audit log entry
Non-EVM chains (Solana, TRON, BTC family) still return intent +
clear 'not implemented' notice — to be added as separate PRs.
Same fix applied to DCA scheduler (_exec_dca): when both
from_wallet_id and to_address are set, actually broadcasts
via _evm_sweep instead of just logging.

Add Cardano (ADA) address generation using the official pycardano
library which implements IOHK's Kholaw (BIP32-Ed25519) derivation
correctly. Hand-rolled Kholaw implementations tend to get subtle
details wrong (HMAC ordering, scalar addition mod L, network byte
values), so we delegate to pycardano.
Verified against:
- pycardano's own Address() output (matches byte-for-byte)
- The official `cardano-address` CLI from IOHK (v4.0.6) — verified
that the spending_key_hash matches exactly:
payment: 9b206f67cc03a2f3cb97988759878715eb387a9eeff9247fedbeb2b8
stake: 45dd8424772e4a23936f6dd23d3e459d8f036a84825dedeff8d26cbc
Implementation:
- chain_addresses.py: cardano_address, cardano_enterprise_address,
cardano_reward_address (all via pycardano)
- generator.py: ada added to CHAIN_ADDRESS_OVERRIDES with curve
'ed25519_kholaw'. The raw 32-byte ed25519 signing key is extracted
from xsk[:32] and returned as private_key_hex. Public key derived
via nacl.crypto_sign_seed_keypair.
- _generate_mnemonic() now always returns str() (was sometimes
Bip39Mnemonic object, which pycardano rejects).
- Added test_cardano_matches_pycardano, test_cardano_testnet,
test_cardano_enterprise_matches_pycardano.
Cardano address types supported:
- Base (addr1... mainnet, addr_test1... testnet) — payment + stake
- Enterprise (addr1v... mainnet) — payment only
- Reward / stake (stake1... mainnet) — stake only
Derivation per CIP-1852:
- payment key: m/1852'/1815'/0'/0/0
- stake key: m/1852'/1815'/0'/2/0
pycardano's actual disk footprint is only 1.1 MB + 9 MB of small deps
(asn1crypto, certvalidator, oscrypto, etc. — most are < 2 MB each).
That's well within budget for a wallet product that needs correct
Cardano addresses.

WalletPress claimed to support 55 chains but ~18 of them produced
addresses no explorer would recognize. This was the worst kind of bug
for a crypto wallet product — silent, undetectable to users, and
direct route to lost funds.
This commit adds:
- wallet_engine/chain_addresses.py (NEW, 433 lines)
Per-chain address encoders using official SDKs / specs:
- bech32 for Cosmos family (atom/osmo/juno/sei/inj/evmos)
- stellar-sdk for Stellar (XLM, base32 + CRC16-XMODEM)
- xrpl-py for XRP (custom base58 alphabet, rpshnaf...)
- manual tz1 watermark impl for Tezos (XTZ, [0x06, 0xA1, 0x9F])
- manual workchain+CRC16 impl for TON (v4r2, 48 base64url chars)
- blake2b-40 base32 impl for Nano (nano_+60 chars)
- f1 + blake2b base32 impl for Filecoin
- SHA-512/256 checksum for Algorand (NOT full SHA-512 — easy to
get wrong, algosdk uses the truncated variant)
- monero library for Monero (XMR)
- substrate-interface for Polkadot/Kusama sr25519
- bitcash for Bitcoin Cash cashaddr
- manual 0x1CB8 prefix impl for Zcash t-addr (was 0x1C)
- wallet_engine/generator.py
New CHAIN_ADDRESS_OVERRIDES table + _generate_with_override() that
dispatches the 17 fixed chains through chain_addresses instead of
the broken family-based dispatch. Also fixed _generate_monero to
use Seed() positional arg (was wrong keyword).
- tests/test_address_vectors.py (NEW, 19 tests)
Golden-vector tests with FIXED test mnemonic. Every test generates
the address with our implementation AND the official SDK, then
asserts byte equality. 19/19 passing.
- backend/requirements.txt
New deps: bech32, stellar-sdk, xrpl-py, py-algorand-sdk, tonsdk,
bitcash, monero, substrate-interface.
- ADDRESS_GENERATION.md
Flipped 17 chains from ❌ BROKEN to ✅ VERIFIED. Cardano still
deferred (needs Bech32 stake address — WP-055).
- AUDIT.md
Marked P0-4 as FIXED.
- BUILDER.md
Marked WP-040 through WP-058 as DONE (except WP-055 Cardano).
