sign-wallet

sign-wallet is a command for Claude Code from hiromaily/go-crypto-wallet. It costs 0 tokens per session (560 once invoked), scanned A, original, MIT.

An offline wallet tool for keeping signing keys away from the internet and adding later signatures to multisignature transactions. A multisignature transaction needs approval from several separate key holders.

In plain words
What is it for?
It helps create wallet seeds and keys, export public keys, import private keys, and add signatures to transactions that other wallets have already signed.
Why use it?
It lets each authorization operator sign independently without exposing their private keys online. This reduces the risk of one online system controlling all approvals.

Token cost

What it costs to keep this loaded

Counted locally with the o200k_base tokenizer, which is exact for GPT models; Claude uses its own tokenizer and its counts differ. Treat this as one consistent yardstick across the catalogue rather than a bill. Prices are per million input tokens.

Security

Grade A, and why

sign-wallet scanned grade A with 0 findings against 26 rules in 11 categories — prompt injection, anti-refusal, data exfiltration, privilege escalation, supply chain, agent snooping, system-prompt leakage, SSRF and excessive agency — measured 8d ago.

A static scan of the body, not an audit. Every finding is printed with the line that produced it so you can judge whether it matters here. A mod is markdown that instructs an agent; that is exactly why what it instructs is worth reading.

Nothing flagged

None of the 26 patterns this scan looks for appear in this file: no shell pipes, no recursive deletes, no credential paths, no hidden text, no instruction-override or anti-refusal phrasing, no agent-config snooping. That is not a guarantee, it is the absence of the things that are checkable.

What it actually says

Sign Wallet Commands

Sign Wallet operates offline as a cold wallet. It provides subsequent signatures (2nd, 3rd, etc.) for multisig transactions. Each authorization operator uses their own Sign Wallet instance.

Create Commands
sign create seed

Creates a seed for the authorization account wallet. If --seed is provided, it will be stored instead of generating a new one.

Options:

  • --seed <string> - Seed value to store (development use only)

Example:

sign create seed
sign create hdkey

Creates HD keys for the authorization account.

Example:

sign create hdkey
Export Commands
sign export fullpubkey

Exports full public key addresses as a CSV file for import into Keygen Wallet. These are used to create multisig addresses.

Example:

sign export fullpubkey
Import Commands
sign import privkey

Imports generated private keys for the authorization account into the database.

Example:

sign import privkey
Sign Commands
sign sign signature

Signs a transaction that has already been signed by Keygen Wallet (or other Sign Wallets). This provides subsequent signatures for multisig addresses.

Options:

  • --file <path> - Path to the signed transaction file

Example:

sign sign signature --file data/tx/btc/tx_signed1_1234567890.json
API Commands

API commands are coin-specific and dynamically configured based on the --coin flag.

Bitcoin/Bitcoin Cash API (sign api with --coin btc or --coin bch)
  • sign api encryptwallet - Encrypts the wallet with a passphrase
    • --passphrase <string> - Passphrase for encryption
  • sign api walletpassphrase - Stores the wallet decryption key in memory
    • --passphrase <string> - Passphrase to unlock the wallet
  • sign api walletpassphrasechange - Changes the wallet passphrase
    • --old <string> - Old passphrase
    • --new <string> - New passphrase
  • sign api walletlock - Locks the wallet by removing the encryption key from memory
Ethereum API (sign api with --coin eth)
  • sign api clientversion - Get client version
  • sign api nodeinfo - Get node information
  • sign api syncing - Get synchronization status
  • sign api netversion - Get network version

What this file has done since we first saw it

Hashed on every crawl. A supply-chain change to an agent config is a question of when, not whether, so the history is kept rather than the latest state alone.
