This helps your agent stay synced with the chain. ### proxy_eth_call Cronoscan executes an eth_call to interact with a smart contract. Use this to test contract logic without sending a transaction. ### proxy_eth_estimate_gas Cronoscan calculates the gas required for a specific transaction. This helps you avoid out-of-gas errors. ### proxy_eth_gas_price Cronoscan checks the current gas price on the Cronos network. Use this to plan your transaction costs. ### proxy_eth_get_block_by_number Cronoscan gets full details for a specific block by its number. This is useful for deep block analysis. ### proxy_eth_get_code Cronoscan retrieves the compiled bytecode of a smart contract. This is useful for low-level contract inspection. ### proxy_eth_get_storage_at Cronoscan reads the storage data at a specific contract slot. Use this for advanced state inspection. ### proxy_eth_get_transaction_by_hash Cronoscan fetches full details for a transaction using its unique hash. This is the best way to see all data for a single transaction. ### proxy_eth_get_transaction_receipt Cronoscan retrieves the receipt for a transaction after it's processed. This confirms the final state of a transaction. ### get_token_balance Cronoscan checks the balance of an ERC20 token for a specific contract address. Use this to see how much of a specific token a wallet holds. ### get_token_nft_tx Cronoscan tracks ERC721 NFT transfer events for a specific address. This lets you monitor NFT trading and movements. ### get_token_supply Cronoscan gets the total supply of an ERC20 token. Use this to check the total amount of a specific token in existence. ### get_token_tx Cronoscan views the transfer history for an ERC20 token at a specific address. This is great for tracking specific token movements. ### get_tx_list_internal Cronoscan lists all internal transactions for a specific wallet address. This reveals complex interactions between contracts. ### get_tx_list Cronoscan lists all normal transactions for a specific wallet address. Use this to see the standard history of a wallet. ### get_balance_multi Cronoscan gets CRO balances for a list of multiple addresses at once. This is useful for tracking several wallets simultaneously. ### get_eth_price Cronoscan checks the latest market price for the CRO token. It gives you real-time pricing data. ### get_eth_supply Cronoscan retrieves the total supply of CRO on the network. Use this to see the total circulating amount. ## Prompt Examples **Prompt:** ``` What's the current price of CRO? ``` **Response:** ``` I've checked the latest market data for you. | Metric | Value | | :--- | :--- | | **Current Price** | $0.98 | | **Total Supply** | 1.2B CRO | | **24h Change** | +2.4% | Would you like me to check the gas price as well? ``` **Prompt:** ``` Show me the last 3 NFT transfers for 0x690B9A9E9aa1C9dB991C7721a92d351Db4FaC990. ``` **Response:** ``` I've retrieved the recent NFT transfer events for that address: * **Transfer 1:** 1x 'CyberPunk #442' to 0x123... (Hash: 0xabc...) * **Transfer 2:** 1x 'Ape #99' to 0x456... (Hash: 0xdef...) * **Transfer 3:** 1x 'MoonCat #12' to 0x789... (Hash: 0xghi...) Let me know if you need the full transaction details for any of these. ``` **Prompt:** ``` Get the ABI for this contract: 0x5C7C6f200567e573C96E38557b2062993894f91a. ``` **Response:** ``` I've successfully fetched the ABI for that contract. It includes the following main functions: * `stake(uint256 amount)` * `withdraw()` * `claimRewards()` * `getPoolSize()` I can help you format a specific call for any of these functions if you'd like. ``` ## Capabilities ### Check wallet balances Cronoscan lets you check CRO balances for one or many addresses at once. ### Track token transfers Cronoscan allows you to monitor ERC-20 and NFT transfer events. ### Inspect smart contracts Cronoscan fetches contract ABIs and verified source code for auditing. ### Monitor network health Cronoscan provides real-time data on gas prices and block rewards. ### Execute RPC calls Cronoscan executes standard Ethereum-compatible RPC calls for advanced interactions. ### Analyze transaction history Cronoscan retrieves transaction histories for both normal and internal types. ## Use Cases ### Debugging a failed swap A developer uses proxy_eth_call to test a contract function and then checks get_tx_receipt_status to see why it failed. ### Whale tracking An analyst asks for the last 10 get_token_tx events for a specific address to see where a large amount of USDC went. ### Portfolio audit A user asks to see the get_balance for five different wallets and the get_token_supply for a new project. ### Security research A researcher pulls the get_source_code of a new DeFi protocol to look for vulnerabilities in the logic. ## Benefits - Stop switching tabs to check balances because get_balance_multi lets you see multiple wallets at once. - Audit contracts faster by pulling source code and ABIs with get_source_code and get_abi. - Monitor market trends instantly using get_eth_price and get_eth_supply for real-time data. - Debug complex interactions by running proxy_eth_call and proxy_eth_estimate_gas directly. - Track whale movements more easily by pulling get_token_tx and get_token_nft_tx for specific addresses. - Get a full history of activity with get_tx_list and get_tx_list_internal to see every move on-chain. ## How It Works The bottom line is you get direct blockchain data without leaving your chat interface. 1.
