RPC Management Commands
RPCs are persisted in ~/.config/openscan-crypto/rpc-config.json. On first use, the skill auto-fetches from @openscan/metadata and selects privacy-first RPCs. All subsequent commands use the persisted config.
Fetch/sync RPCs from metadata
crypto-cli.mjs rpc-fetch # Sync all networks from @openscan/metadata crypto-cli.mjs rpc-fetch ethereum # Sync a specific network Resolves the latest metadata version dynamically from npm. Auto-selects RPCs (privacy-first, open-source preferred).
List RPCs
crypto-cli.mjs rpc-list ethereum # Show active (configured) RPCs crypto-cli.mjs rpc-list ethereum --all # Show ALL available RPCs from metadata crypto-cli.mjs rpc-list ethereum --all --private # Only privacy (tracking:none)
Configure RPCs
crypto-cli.mjs rpc-set ethereum --strategy race # Set strategy: fallback|race|parallel crypto-cli.mjs rpc-set ethereum --add https://my-rpc.com # Add custom RPC crypto-cli.mjs rpc-set ethereum --remove https://rpc.com # Remove an RPC crypto-cli.mjs rpc-set ethereum --rpcs url1 url2 url3 # Replace all RPCs crypto-cli.mjs rpc-set ethereum --private-only # Keep only tracking:none crypto-cli.mjs rpc-set ethereum --reset # Reset to metadata defaults crypto-cli.mjs rpc-set --default-strategy parallel # Set global default strategy crypto-cli.mjs rpc-set --max-rpcs 3 # Set global max RPCs per network
Reorder RPCs
crypto-cli.mjs rpc-order ethereum --benchmark # Auto-sort by latency (fastest first) crypto-cli.mjs rpc-order ethereum --swap 1 3 # Swap positions 1 and 3 crypto-cli.mjs rpc-order ethereum <url> --position 1 # Move URL to position 1
Test/benchmark RPCs
crypto-cli.mjs rpc-test ethereum # Test all configured RPCs crypto-cli.mjs rpc-test ethereum --all # Test ALL available from metadata crypto-cli.mjs rpc-test ethereum <url> # Test a specific URL Tests latency, block number, client version. Detects out-of-sync nodes via block delta.
View/set default strategy
crypto-cli.mjs rpc-strategy # View defaults + per-network overrides crypto-cli.mjs rpc-strategy parallel # Set global default to parallel
Aggregate address information
crypto-cli.mjs address-info <address> # Full address info crypto-cli.mjs address-info vitalik.eth # ENS name supported crypto-cli.mjs address-info <address> --chain base # On another chain crypto-cli.mjs address-info <address> --private # Privacy RPCs only Returns in a single call: type: EOA or contract (with codeSize if contract) balance: native balance (ETH/MATIC/BNB, etc.) txCount: total transaction count (nonce) ensName: primary ENS name via reverse lookup (Ethereum mainnet only) label: metadata label if the address is a known entity (name, tags, description, website) explorerLink: direct link to the OpenScan explorer This command fires balance, code, and nonce in parallel, then enriches the result with ENS reverse resolution and metadata label lookup.
On-chain token price (100% on-chain, no CoinGecko)
crypto-cli.mjs price # ETH price (default) crypto-cli.mjs price BTC # BTC price (via WBTC pools on mainnet) crypto-cli.mjs price --chain polygon # MATIC price crypto-cli.mjs price --chain bnb # BNB price crypto-cli.mjs price --chain arbitrum # ETH price (fetched from mainnet for L2s) Fetches prices from Uniswap V2-style DEX pools. Uses median of multiple pools for manipulation resistance. Returns per-pool breakdown.
Decode transaction (function call + events)
crypto-cli.mjs decode-tx <0xhash> # Decode function + events crypto-cli.mjs decode-tx <0xhash> --chain arbitrum # On another chain Decodes transaction input data into human-readable function name + parameters. Also decodes all event logs in the receipt. Uses local database of known selectors + 4byte.directory fallback. Identifies tx type: transfer, contract_call, or contract_creation. Strategies: fallback — Try RPCs in order, move to next on failure. Default. Most conservative. race — Fire all RPCs simultaneously, use fastest response. Best for latency. parallel — Fire all, compare results, detect inconsistencies. Trustless verification.
EVM Query Commands
All EVM commands accept --chain <chain> (default: ethereum) and --private (use tracking:none RPCs only).
Check balance
crypto-cli.mjs balance <address> # Native balance (ETH) crypto-cli.mjs balance vitalik.eth # ENS name supported crypto-cli.mjs balance <address> --token USDC # + ERC20 balance crypto-cli.mjs balance <address> --chain arbitrum # On Arbitrum crypto-cli.mjs balance <address> --token USDC --chain base # USDC on Base Returns native balance in human-readable format (e.g., "32.12 ETH") plus raw wei. Token balance includes symbol, decimals, and formatted amount.
Multi-chain balance
crypto-cli.mjs multi-balance <address> # All mainnet chains crypto-cli.mjs multi-balance vitalik.eth # ENS supported crypto-cli.mjs multi-balance <address> --private # Privacy RPCs only Queries the same address across ALL mainnet EVM chains in parallel. Shows balances sorted by chains with funds first.
Get block info
crypto-cli.mjs block # Latest block crypto-cli.mjs block latest # Same crypto-cli.mjs block 19000000 # By number crypto-cli.mjs block 0xabcdef... # By hash (66 chars) Returns: number, hash, timestamp, gasUsed, gasLimit, baseFee, txCount, miner.
Transaction details
crypto-cli.mjs tx <0xhash> crypto-cli.mjs tx <0xhash> --chain arbitrum Returns: hash, blockNumber, from, to, value (in ETH), gasPrice, nonce, input data.
Transaction receipt
crypto-cli.mjs receipt <0xhash> Returns: status (success/reverted), gasUsed, effectiveGasPrice, contract address (if deploy), logs with decoded event names from metadata.
Gas prices
crypto-cli.mjs gas # Ethereum gas crypto-cli.mjs gas --chain base # Base gas crypto-cli.mjs gas --chain arbitrum # Arbitrum gas Returns: gasPrice, maxPriorityFeePerGas, baseFee — all in gwei.
Read contract (eth_call)
crypto-cli.mjs call <to_address> <calldata_hex> [--block <tag>] For raw contract reads. Use for custom ABI calls.
Event logs
crypto-cli.mjs logs --address <contract> --topic <topic_hash> [--from <block>] [--to <block>] Returns up to 50 logs. Default range: latest block only.
Check if address is contract
crypto-cli.mjs code <address> Returns: isContract (bool), codeSize, truncated bytecode.
Transaction count (nonce)
crypto-cli.mjs nonce <address>
Bitcoin Commands
Bitcoin queries use the mempool.space REST API (no JSON-RPC needed).
Blockchain overview
crypto-cli.mjs btc-info Returns: block height, best hash, difficulty, mempool stats, recommended fees — all in one call.
Block details
crypto-cli.mjs btc-block # Latest block crypto-cli.mjs btc-block 800000 # By height crypto-cli.mjs btc-block 0000000... # By hash (64 chars)
Transaction details
crypto-cli.mjs btc-tx <txid> Returns: confirmation status, fee (sats + BTC), fee rate (sat/vB), inputs/outputs with addresses and values.
Mempool state
crypto-cli.mjs btc-mempool Returns: tx count, vsize, total fees, recommended fee rates, 5 most recent txs.
Fee estimates
crypto-cli.mjs btc-fee Returns: fastest, halfHour, hour, economy, minimum — all in sat/vB.
Address balance
crypto-cli.mjs btc-address <address> Returns: balance (BTC + sats), total received/sent, tx count, UTXO count.

Output
All commands output JSON to stdout. The agent can parse and format as needed. Numeric values are pre-formatted: Balances: human-readable (e.g., "32.12 ETH") + raw wei Gas: in gwei Timestamps: ISO 8601 Hex numbers: converted to decimal strings
Explorer Links
EVM commands that return on-chain entities include an explorerLink field with a direct URL to openscan.eth.link: CommandexplorerLink points tobalanceaddress pagemulti-balanceaddress page per chainblockblock pagetxtransaction pagereceipttransaction pagecodeaddress pagenonceaddress pagetokentoken contract address pagelogstransaction page per logbtc-blockBitcoin block pagebtc-txBitcoin transaction pagebtc-addressBitcoin address pageaddress-infoaddress page URL patterns: EVM: https://openscan.eth.link/#/{chainId}/{type}/{id} Bitcoin mainnet: https://openscan.eth.link/#/btc/{type}/{id} Bitcoin testnet4: https://openscan.eth.link/#/tbtc/{type}/{id} Always show this link to the user so they can explore the data further in the UI.
Caching
Metadata cached in ~/.cache/openscan-crypto/ (6h TTL). RPC responses are NOT cached.
ENS Support
All EVM address commands accept .eth names (e.g., vitalik.eth). ENS is resolved on Ethereum mainnet automatically. Works with: balance, multi-balance, code, nonce.
Security
READ-ONLY — no transaction signing, no private key handling Public RPCs — no API keys needed --private flag restricts to tracking:none RPCs Dangerous methods (sendTransaction, etc.) are NOT exposed
