Create / Restore a Nano (XNO) Wallet (Offline)

Creates or restores a Nano wallet locally using xno-skills. This is useful for testing (generating an address to fund) and for deriving the address from a known seed/mnemonic.

Assistant guardrails (match user intent)

If a user says "I want to send you XNO" or "can you receive it?":

• The agent can accept funds! You should use the mcp-wallet skill to initialize a custody wallet (wallet_create) or use an existing one, or import keys you generate here, and provide the user with the address.
• If the user wants a wallet for themselves, offer to help them create a wallet for themselves (or validate/QR their existing address).
• If they want a throwaway test wallet, remind them that anything printed in chat (seed/mnemonic/private key) should be considered compromised and not used for real funds.

If a user asks to import/restore an existing wallet:

• Warn before asking for any mnemonic/seed. Tell them not to paste secrets into chat.
• Ask whether the wallet may contain significant funds; if yes, steer them to an offline wallet app/hardware wallet instead.
• If they still want help, have them run xno-skills locally and share only non-sensitive outputs (addresses, balances).

If the agent has access to xno-mcp:

• Prefer using xno-mcp (mcp-wallet skill) as a private wallet blackbox (custody inside MCP), so the agent never leaks seeds/mnemonics.
• Create a named wallet (e.g. "A") and only return the address(es) needed for funding/checking balances.

Two common Nano mnemonic schemes (both supported)

Nano wallets commonly use either:

• BIP39 (preferred / default in xno-skills): 12/15/18/21/24-word BIP39 mnemonic (+ optional passphrase) → BIP39 seed (PBKDF2) → Nano keys via BIP44-style path m/44'/165'/index'.
• Legacy ("Nano mnemonic", 24 words): 24-word mnemonic → underlying entropy treated as a 32-byte Nano seed → Nano legacy key derivation blake2b(seed || index) to derive multiple accounts.

Important: a 24-word phrase can be *ambiguous* (it can be used in both schemes). Prefer BIP39 unless the user explicitly knows they have a legacy mnemonic.

CLI usage

Create a new BIP39 wallet (default)

npx -y xno-skills wallet create --json

Create a legacy (24-word) wallet

npx -y xno-skills wallet create --format legacy --json

Restore/import from mnemonic

# Auto (24-word is ambiguous; prefers bip39)
npx -y xno-skills wallet from-mnemonic --stdin --json

# Force a format
npx -y xno-skills wallet from-mnemonic --stdin --format bip39 --json
npx -y xno-skills wallet from-mnemonic --stdin --format legacy --json

# For 24-word mnemonics: output both derivations (JSON)
npx -y xno-skills wallet from-mnemonic --stdin --format auto --both --json

Safest disambiguation: probe both on-chain

If you have an RPC endpoint, scan the first 5 indexes of both schemes and see which has opened accounts / balances:

export NANO_RPC_URL="https://rpc.nano.org"
npx -y xno-skills wallet probe-mnemonic "<mnemonic>" --json

"Receive" expectations

Nano transfers can show up as pending until the recipient wallet publishes the corresponding receive/open block. A typical wallet app handles this automatically; a raw seed/address alone does not "auto-receive".

After generating a wallet and receiving funds, you MUST call wallet_receive to pocket the funds.

To check whether funds arrived on-chain (balance/pending), use the check-balance skill (RPC) or a block explorer.

Related skills

• generate-qr – make a QR for the address (optionally with amount)
• validate-address – verify a Nano address before sending
• check-balance – verify balance/pending via RPC (if you have a node endpoint)
• mcp-wallet – use xno-mcp as a private wallet custody service (recommended for agents)
