From 5cfd390e0b46363f9d8ff705728924827515e09e Mon Sep 17 00:00:00 2001 From: santiagocetran Date: Fri, 3 Jul 2026 12:27:07 -0300 Subject: [PATCH 01/12] feat(wallet): in-memory password cache, --keystore import, named multi-account store, list-accounts MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Security-sensitive keystore work for task_300626_3 Part 1 (P3-T0.2b). Flag for Umer's needs-security-review before merge. - In-memory TTL password cache (_PASSWORD_CACHE) replaces the on-disk CONFIG_DIR/.session cache; stale .session files are cleaned up on load. No cross-invocation persistence by design (D1) — only DIN_WALLET_PASSWORD env avoids re-prompting across commands. - connect-wallet --keystore : imports a standard eth-account JSON keystore, validates by decrypting to derive the checksum address, preserves the original keystore verbatim. - Named multi-account keystore: CONFIG_DIR/wallets/wallet_.json with a shared wrapper schema ({version, address, keystore, source, name}); _extract_keystore() normalizes wrapper/bare/demo forms. connect-wallet --name saves under that name; legacy wallet.json still loads as "default" (named default wins over legacy when both exist). - validate_account_name() enforces ^[A-Za-z0-9_-]{1,64}$ and is called from wallet_path_for_name() itself, the one function every read/write path funnels through — so path safety is a boundary invariant, not something every caller has to remember. - Atomic writes (temp file at 0o600 + os.replace + defensive chmod) so wallet files end up 0o600 even when overwriting a pre-existing loose-permission file; wallets/ dir created at 0o700. - New `dincli system list-accounts` command enumerates named wallets + legacy wallet.json without decrypting, dedups so a named default hides the legacy row. - read_wallet/todo updated to resolve the active named wallet instead of hardcoding legacy wallet.json.

Lighthouse (Filecoin) provider adapter + IPFS_PROVIDER env var + provider-scoped API keys (D6/D7) MIME-Version: 1.0 Content-Type: text/plain; charset=UTF-8 Content-Transfer-Encoding: 8bit Part 2 of task_300626_3 (Filecoin Provider Adapter), per Plans/part2-filecoin-lighthouse.md. - New dincli/services/ipfs_lighthouse.py: upload_via_lighthouse posts to upload.lighthouse.storage/api/v0/add with Bearer auth and extracts the nested data.Hash response shape (different from Filebase's flat shape); retrieve_via_lighthouse gets from gateway.lighthouse.storage/ipfs/{cid} (no auth). Malformed responses raise a clear RuntimeError instead of leaking KeyError/JSONDecodeError. - Wired into ipfs.py's upload_to_ipfs/retrieve_from_ipfs dispatch as a genuine first-class provider ("lighthouse" in SUPPORTED_IPFS_PROVIDERS), not the generic dynamic-module "custom" path (D5) — matches the task's concrete deliverables (dedicated module, dedicated env var, dedicated test file). - D6: resolve_ipfs_config() now also checks IPFS_PROVIDER env var as a fallback when no ipfs_provider is set in config (config wins if set); applies to all providers, not just Lighthouse. - D7: API keys are now stored per-provider (ipfs_api_key_) instead of one flat ipfs_api_key field, fixing a silent-misconfiguration bug — switching from Filebase to Lighthouse without a fresh --api-key no longer silently reuses the Filebase token. Legacy flat ipfs_api_key still resolves for filebase (back-compat); LIGHTHOUSE_API_KEY env var is a fallback for lighthouse. - configure_ipfs validates each provider's key independently.

Keystore non-secret validation (exists/parse/_extract_keystore) is hoisted above the guard; the passphrase getpass + decrypt stay after it, so no secret is requested before the overwrite decision and a doomed --keystore fails fast without prompting. Guard keys on the exact target file; a legacy wallet.json for 'default' is a non-destructive migration and intentionally not guarded. Docstring corrected: demo mode is config-driven, not tied to --yes. #3 — new-wallet password: _get_password gains is_new_wallet; when creating or overwriting a wallet the in-memory cache is skipped so a fresh keystore is never silently encrypted with a stale cached password. DIN_WALLET_PASSWORD env is still honored (deliberate automation path); only the cache is ignored. #5 — single .env parse per unlock: load_account fetches DIN_WALLET_PASSWORD once and threads it into _get_password/_cache_password_in_memory via an _UNSET sentinel, instead of each self-parsing .env (get_env_key is not memoized). Callers that omit env_pass self-fetch as before.

Verdict is scoped: CONFIRMED that OWS can sign an EVM tx without exposing the private key (verified via CLI and in-process Python SDK, byte-identical, signer recovers to the OWS address); NOT proven for the stronger production claim of mandatory scoped-policy delegation — the verified path is unscoped local vault signing that isn't even passphrase-gated. Policy-enforced signing, passphrase behavior, and an eth-account-compatible adapter are follow-up work. Also corrects wallet-setup.md, which shipped a broken flow: OWS does NOT export an Ethereum JSON keystore (ows wallet export prints the raw secret, interactive only), so the 'export keystore -> connect-wallet --keystore' loop can't work. Fixed the duplicate import, made the imported wallet active (set-wallet), fixed the delegation status (planned, not shipped) and the policy guidance, and showed the actual export command. --- .../discussion/ows-delegation-feasibility.md | 188 ++++++++++++++++++ Documentation/guides/wallet-setup.md | 124 +++++++----- 2 files changed, 259 insertions(+), 53 deletions(-) create mode 100644 Developer/discussion/ows-delegation-feasibility.md diff --git a/Developer/discussion/ows-delegation-feasibility.md b/Developer/discussion/ows-delegation-feasibility.md new file mode 100644 index 0000000..e2f1716 --- /dev/null +++ b/Developer/discussion/ows-delegation-feasibility.md @@ -0,0 +1,188 @@ +# OWS (Open Wallet Standard) delegation — feasibility spike + +**Author:** Santiago Rodriguez Cetran +**Date:** 2026-07-07 +**Context:** `task_300626_3` §1c ("OWS integration exploration") · PR #16 review follow-up +**Status:** Hands-on spike complete.

Note: the bundled agent skill doc is +**v1.3.2** and is stale relative to the 1.4.2 package — this explains two discrepancies below +(import name and vault layout). + +--- + +## Why this exists + +The task asked whether `dincli` can use OWS as an account backend — enumerate accounts and +request a **signed transaction without ever handling the raw key** — and what the failure +modes are. The first pass answered from documentation only; the PR #16 review flagged that as +a gap. This document records an actual spike: OWS installed, wallets created and inspected on +disk, a real Optimism Sepolia transaction signed and cryptographically verified. + +**Method:** local-verify (no on-chain broadcast, no funds). A signature is proven correct by +recovering the signer address from it — no funds and no private key required. + +## Verdict — scoped precisely + +- **CONFIRMED:** OWS can sign an EVM (Optimism Sepolia, chainId 11155420) transaction and + return a signature that recovers to its own account, **without exposing the private key** to + the caller. `dincli` can enumerate accounts and drive this via CLI subprocess or the + in-process Python SDK. No daemon required. +- **NOT yet proven (do not ship on this basis):** the stronger production claim — *"`dincli` + can safely support OWS delegation with a mandatory, scoped signing policy."* The verified + path is **unscoped local vault signing by wallet name**, which appears to bypass the + policy/API-key layer entirely, and (see below) is **not even passphrase-gated**. Policy- + enforced signing (the `key`/`policy` "agent access layer", and any REST/MCP transport) was + **not exercised**. Until that is tested end-to-end — plus passphrase behavior and adapter + compatibility — OWS delegation is a **follow-up**, not a production recommendation. + +## What OWS is (verified from the running binary + on-disk vault) + +`ows` 1.4.2 — a local, multi-chain wallet manager (Rust core). Keys live in an encrypted vault +under `~/.ows/wallets/.json` (flat file per wallet; `ows_version: 2`. The v1.3.2 skill +doc's `~/.ows/wallets//wallet.json` layout is stale). **Crypto confirmed by reading the +keystore file directly** (not just docs): `crypto.cipher = "aes-256-gcm"`, `crypto.kdf = +"scrypt"` (cost params in `crypto.kdfparams`; `auth_tag`, `cipherparams`, `ciphertext` +present). One mnemonic derives addresses for 12+ chains via BIP-44. + +Access surfaces: **CLI**, **Node SDK** (`@open-wallet-standard/core`), **Python SDK** +(`open-wallet-standard`, PyO3 — Rust core in-process; import as `ows`). Install: +`curl -fsSL https://docs.openwallet.sh/install.sh | bash` (global `npm install -g +@open-wallet-standard/core` also provides the CLI). Command surface: +`wallet {create,import,export,delete,rename,list,info}`, `sign {message,tx,send-tx}`, +`key {create,list,revoke}`, `policy {create,list,show,delete}`, `mnemonic`, `fund`, `pay` +(x402), `config show`. + +## The four task questions, answered with evidence + +### 1. What interface does OWS expose? +CLI subprocess **and** an in-process Python SDK (`import ows`). Both produced a byte-identical +signature for the same input; no daemon/socket. A `key`/`policy` "agent access layer" with +scoped tokens exists in the command surface but its enforcement path (and any REST/MCP +transport) was **not exercised in this spike**. + +### 2. Can `dincli` enumerate accounts? +Yes. `ows wallet list` (CLI) and `ows.list_wallets()` (SDK) return structured data; each wallet +lists per-chain accounts, e.g. `{"chain_id":"eip155:1","address":"0x…","derivation_path": +"m/44'/60'/0'/0/0"}`. + +### 3. Can `dincli` request a signed tx without holding the raw key? +Yes (for EVM, unscoped local signing). `ows sign tx --wallet --chain 11155420 --tx +` and `ows.sign_transaction(,"11155420",)` both return a 65-byte +compact signature (`r‖s‖recovery_id`) — **not** an assembled tx, so the caller reassembles it +(or uses `sign send-tx --rpc-url …` to broadcast). Verified two independent ways (recover from +the signing hash via `eth_keys`, and `Account.recover_transaction()` on the reassembled raw +tx): both recover exactly the wallet's own address. See the transcript under **Reproduction**. + +### 4. Chain / account mapping (verified) +For EVM, OWS derives **one** secp256k1 account (`m/44'/60'/0'/0/0`) shared across all `eip155:*` +chains, so the enumerated `eip155:1` address **is** the signer for `--chain 11155420`. Proven: +the address recovered from a chainId-11155420 signature equalled the enumerated `eip155:1` +address byte-for-byte. The chainId only affects the signed payload (it is embedded in the tx +bytes). `dincli` would map its network → OWS `--chain ` (e.g. `sepolia_op_devnet` +→ `11155420`). Note: `ows config show` ships **no RPC for `eip155:11155420`** — irrelevant for +offline `sign tx` (which `dincli` broadcasts itself via its own `w3`), but `sign send-tx` would +need an explicit `--rpc-url`. + +### 5. Failure modes (all exercised) + +| Scenario | Observed | +|---|---| +| OWS not installed | exit **127**, `No such file or directory` — clean `FileNotFoundError` for fallback | +| Unknown wallet name | exit **1**, `error: wallet not found: ''` | +| Wrong chain (EVM bytes, `--chain solana`) | exit **1**, cryptic: `invalid transaction: transaction too short for declared signature slots` | +| Malformed tx bytes (`0xdeadbeef`) | ⚠️ exit **0** — **signed blindly** (see caveat 1) | +| Wrong passphrase (via SDK) | `RuntimeError: decryption failed: aead::Error` (clean failure) | +| "OWS not running" | N/A — no daemon; CLI/SDK are one-shot/in-process | + +## Passphrase / authentication of local signing — material finding + +In v1.4.2 there is **no CLI or env way to create a passphrase-protected wallet**: `ows wallet +create`/`import` expose no passphrase option, and `OWS_PASSPHRASE` at creation was **ignored** +(the resulting wallet signed with no secret and rejected `passphrase="secret"` with +`aead::Error`). Consequences for the verified flow: + +- A CLI-created OWS wallet is encrypted at rest but effectively **empty-passphrase**: `ows sign + tx`/`sign_transaction()` decrypt and sign with **no secret from the caller**. Protection + reduces to **filesystem permissions on `~/.ows/wallets/`**. +- This is **weaker** than `dincli`'s own encrypted keystore, which *requires* a passphrase to + decrypt. So the "highest security / dincli never sees the key" framing is only half-true: the + key isn't exposed to `dincli`, but neither is it passphrase-gated in the path we verified. +- The passphrase param *is* the KDF input (a wrong one fails with `aead::Error`), so a + passphrase-protected mode presumably exists via some path we did not find — that, plus + non-interactive credential passing without leaking through args/env/shell history, is + **untested and part of the follow-up**. + +## Security caveats + +1. **Blind signing.** `ows sign tx` (EVM) signs arbitrary bytes without validating they decode + as a well-formed tx (`0xdeadbeef` → exit 0 + signature). The caller owns payload correctness. +2. **Unscoped API keys, and policy enforcement unverified.** `ows key create --name X --wallet + Y` succeeds with **no `--policy`**, minting a token that can sign anything for that wallet. + Whether attaching a policy actually blocks a disallowed tx was **not tested** — the verified + local-signing path does not go through the key/policy layer at all. +3. **Unauthenticated local signing** (see the passphrase section) — filesystem-permission-only + protection in the verified flow. + +## Integration seam (for a future opt-in — larger than a drop-in) + +Every signature funnels through `DinContext.account`, used at `dincli/cli/utils.py:881` +(`signed_tx = account.sign_transaction(tx)`) and `dincli/cli/system.py:589`, followed by +`w3.eth.send_raw_transaction(signed_tx.raw_transaction)`. So an `OwsAccount` adapter must be +**eth-account-compatible**, not a thin shim — it has to: + +1. expose `.address` (from `list_wallets`, the `eip155:*` account); +2. accept a **web3 transaction dict** (as produced by `contract_function.build_transaction(...)` + / the ETH-transfer dict), including EIP-1559 fee fields; +3. **serialize** it to unsigned typed (EIP-1559) transaction bytes; +4. call `ows.sign_transaction(...)` to get `r/s/recovery_id`; +5. **reassemble** the signed raw tx (`0x02 || rlp([...,y_parity,r,s])`); +6. return a result object exposing **`.raw_transaction`** (and ideally `.hash`, `.r`, `.s`, `.v`) + so the existing `send_raw_transaction(signed_tx.raw_transaction)` call sites are unchanged. + +Gate on `ows`/`open-wallet-standard` being importable; fall back to the keystore path. + +## Recommendation + +- **Ship named multi-keystore as the default production path** (merged, self-contained, no + external dependency, passphrase-gated). +- **Treat OWS delegation as a follow-up, not production-ready as described.** EVM signing + without key exposure is genuinely feasible and low-integration-cost via the Python SDK — but + before recommending it for production the follow-up must verify end-to-end: (a) **policy- + enforced** signing (create a policy, scope an API key to it, confirm a disallowed tx is + rejected); (b) **passphrase-protected** wallets and non-interactive credential passing without + leaking secrets; (c) the eth-account-compatible **adapter** above.
