SKILL: wallet-mcp

description: Multi-chain wallet generator and manager. Supports Solana and EVM. All outputs are JSON. version: 1.4.0 tool_path: ~/.openclaw/tools/wallet.py invoke: python3 ~/.openclaw/tools/wallet.py

IMPORTANT — Always use wallet.py

NEVER use built-in blockchain tools (e.g. SOLANA(), EVM()) for wallet operations. ALWAYS call python3 ~/.openclaw/tools/wallet.py <command> instead. This applies to ALL wallet, balance, token, sweep, and transfer requests.

wallet.py is SYNCHRONOUS — every command runs to completion and returns JSON immediately. There is NO background task, NO session ID, NO process polling, NO process command. Do NOT invent commands like process --action poll or process --action kill — they do not exist. If a command takes time (e.g. sending to 100 wallets), it simply runs and returns when done.

Command disambiguation

User saysCorrect command
scan token accounts for wallet ADDRESSscan_token_accounts --address ADDRESS
scan token balances for group LABELscan_token_balances --chain solana --label LABEL
check token accounts on So1ana...scan_token_accounts --address So1ana...
show all tokens held by wallets in airdrop1scan_token_balances --chain solana --label airdrop1

scan_token_accounts = one wallet address, no token filter required, returns all SPL accounts. scan_token_balances = a wallet group (label), token filter optional, returns balances.

generate_wallets

Generate N new wallets and save them under a label.

command: python3 {tool_path} generate_wallets --chain <solana|evm> --count <N> --label <label> [--tags <tag1|tag2>]

Example:

python3 ~/.openclaw/tools/wallet.py generate_wallets --chain solana --count 50 --label airdrop1

send_native_multi

Send SOL or ETH from ONE source wallet to ALL wallets in a group (one-to-many). --label is the DESTINATION GROUP — NOT a single address. There is NO send_native_single command. Use this for group sends only.

Sender can be specified two ways (use --from-label when possible — avoids raw key in chat):

  • --from-label <LABEL> — look up sender by label from storage (PREFERRED)
  • --from-key <PRIVATE_KEY> — pass raw private key directly
command: python3 {tool_path} send_native_multi (--from-label <LABEL> | --from-key <KEY>) --label <label> --amount <AMOUNT> --chain <solana|evm> [--rpc <URL>] [--tag <tag>] [--randomize] [--delay-min 1] [--delay-max 30] [--retries 3]

Example:

python3 ~/.openclaw/tools/wallet.py send_native_multi --from-label main --label airdrop1 --amount 0.001 --chain solana

sweep_wallets

Collect all SOL or ETH from every wallet in a group back to one destination. Each wallet sends its full balance minus a small fee reserve.

Destination can be specified two ways (use --to-label when possible):

  • --to-label <LABEL> — look up destination address by label from storage (PREFERRED)
  • --to-address <ADDRESS> — pass raw public address directly
command: python3 {tool_path} sweep_wallets (--to-label <LABEL> | --to-address <ADDRESS>) --chain <solana|evm> [--label <label>] [--tag <tag>] [--rpc <URL>] [--leave-lamports 5000] [--delay-min 1] [--delay-max 10] [--retries 3]

Example:

python3 ~/.openclaw/tools/wallet.py sweep_wallets --to-label main --chain solana --label airdrop1

list_wallets

List wallets with optional filters. Private keys are masked by default.

command: python3 {tool_path} list_wallets [--chain <solana|evm>] [--label <label>] [--tag <tag>] [--show-keys]

get_balance_batch

Fetch native balances for a wallet group.

command: python3 {tool_path} get_balance_batch [--chain <solana|evm>] [--label <label>] [--tag <tag>] [--rpc <URL>]

scan_token_balances

Scan SPL token balances across a Solana group (all tokens, or filter by mint), or ERC-20 token balances across an EVM group (contract address required).

command: python3 {tool_path} scan_token_balances --chain <solana|evm> [--label <label>] [--tag <tag>] [--token <MINT_OR_CONTRACT>] [--rpc <URL>]

Example:

python3 ~/.openclaw/tools/wallet.py scan_token_balances --chain solana --label airdrop1
python3 ~/.openclaw/tools/wallet.py scan_token_balances --chain evm --label eth_test --token 0xA0b86991c6218b36c1d19D4a2e9Eb0cE3606eB48

export_wallets

Export a wallet group to a JSON or CSV file for backup or offline use. Private keys are excluded by default. Use --include-keys if the file will be re-imported. Omit --path — the file is auto-saved to ~/.wallet-mcp/exports/ with a timestamp name. Only specify --path if the user explicitly asks for a custom file location.

command: python3 {tool_path} export_wallets [--chain <solana|evm>] [--label <label>] [--tag <tag>] [--format <json|csv>] [--include-keys] [--path <FILE>]

Example (standard — no --path needed):

python3 ~/.openclaw/tools/wallet.py export_wallets --label airdrop1 --format json
python3 ~/.openclaw/tools/wallet.py export_wallets --label airdrop1 --format json --include-keys

add_wallet

Import a single wallet by private key. The public address is derived automatically. Use this to register the "main" sender/destination wallet without needing to know its address.

command: python3 {tool_path} add_wallet --private-key <KEY> --chain <solana|evm> --label <label> [--tags <tag1|tag2>]

Example:

python3 ~/.openclaw/tools/wallet.py add_wallet --private-key 4uBCZyvJ...ZgJX --chain solana --label main

import_wallets

Import wallets from a JSON or CSV file into local storage. Duplicate addresses are skipped automatically. IMPORTANT: The source file MUST contain private keys (exported with --include-keys). Importing a file without private keys will fail for every row.

command: python3 {tool_path} import_wallets --path <FILE> [--format <auto|json|csv>] [--label <label>] [--tags <tag1|tag2>]

Example:

python3 ~/.openclaw/tools/wallet.py import_wallets --path /backups/airdrop1_full.json --label airdrop2 --tags restored

close_token_accounts

Close empty SPL token accounts and reclaim rent SOL. (Solana only)

command: python3 {tool_path} close_token_accounts --private-key <KEY_B58> [--rpc <URL>] [--close-non-empty]

scan_token_accounts

Scan all SPL token accounts for a single Solana wallet address (read-only, no changes). Takes a public key — NOT a label. No token filter needed; returns all accounts.

command: python3 {tool_path} scan_token_accounts --address <PUBKEY> [--rpc <URL>]

Example:

python3 ~/.openclaw/tools/wallet.py scan_token_accounts --address 6ydKarjw1WhrkqH7oFncSKEH1sYUf6j8s6s5WSRFhGTZ

tag_wallets

Add a tag to all wallets in a label group.

command: python3 {tool_path} tag_wallets --label <label> --tag <tag>

group_summary

Show all wallet groups with counts per chain. Takes NO arguments.

command: python3 {tool_path} group_summary

Example:

python3 ~/.openclaw/tools/wallet.py group_summary

delete_group

Permanently delete all wallets in a group by label.

command: python3 {tool_path} delete_group --label <label>
