Balance and Transaction Data ### [eth\_getBalance](/sdks/base-account/reference/core/provider-rpc-methods/eth_getBalance) Returns the balance of the account of given address. ### [eth\_getTransactionCount](/sdks/base-account/reference/core/provider-rpc-methods/eth_getTransactionCount) Returns the number of transactions sent from an address. ### [eth\_getTransactionByHash](/sdks/base-account/reference/core/provider-rpc-methods/eth_getTransactionByHash) Returns information about a transaction by transaction hash. ### [eth\_getTransactionReceipt](/sdks/base-account/reference/core/provider-rpc-methods/eth_getTransactionReceipt) Returns the receipt of a transaction by transaction hash. ## Block Information ### [eth\_getBlockByNumber](/sdks/base-account/reference/core/provider-rpc-methods/eth_getBlockByNumber) Returns information about a block by block number. ### [eth\_getBlockByHash](/sdks/base-account/reference/core/provider-rpc-methods/eth_getBlockByHash) Returns information about a block by block hash. ### [eth\_getBlockTransactionCountByNumber](/sdks/base-account/reference/core/provider-rpc-methods/eth_getBlockTransactionCountByNumber) Returns the number of transactions in a block by block number. ### [eth\_getBlockTransactionCountByHash](/sdks/base-account/reference/core/provider-rpc-methods/eth_getBlockTransactionCountByHash) Returns the number of transactions in a block by block hash. ## Transaction Methods ### [eth\_sendTransaction](/sdks/base-account/reference/core/provider-rpc-methods/eth_sendTransaction) Creates new message call transaction or a contract creation for signed transactions. ### [eth\_sendRawTransaction](/sdks/base-account/reference/core/provider-rpc-methods/eth_sendRawTransaction) Creates new message call transaction or a contract creation for signed transactions. ## Gas and Fee Methods ### [eth\_estimateGas](/sdks/base-account/reference/core/provider-rpc-methods/eth_estimateGas) Generates and returns an estimate of how much gas is necessary to allow the transaction to complete. ### [eth\_gasPrice](/sdks/base-account/reference/core/provider-rpc-methods/eth_gasPrice) Returns the current price per gas in wei. ### [eth\_feeHistory](/sdks/base-account/reference/core/provider-rpc-methods/eth_feeHistory) Returns base fee per gas and transaction effective priority fee per gas history for the requested/supported block range. ## Contract and Storage Methods ### [eth\_getCode](/sdks/base-account/reference/core/provider-rpc-methods/eth_getCode) Returns code at a given address. ### [eth\_getStorageAt](/sdks/base-account/reference/core/provider-rpc-methods/eth_getStorageAt) Returns the value from a storage position at a given address. ### [eth\_getLogs](/sdks/base-account/reference/core/provider-rpc-methods/eth_getLogs) Returns an array of all logs matching a given filter object. ### [eth\_getProof](/sdks/base-account/reference/core/provider-rpc-methods/eth_getProof) Returns the account and storage values of the specified account including the Merkle-proof. ## Signing Methods ### [personal\_sign](/sdks/base-account/reference/core/provider-rpc-methods/personal_sign) Signs a message with the private key of the given account. ### [eth\_signTypedData\_v4](/sdks/base-account/reference/core/provider-rpc-methods/eth_signTypedData_v4) Signs typed data according to EIP-712. ## Network Methods ### [wallet\_addEthereumChain](/sdks/base-account/reference/core/provider-rpc-methods/wallet_addEthereumChain) Adds an Ethereum chain to the wallet. ### [wallet\_switchEthereumChain](/sdks/base-account/reference/core/provider-rpc-methods/wallet_switchEthereumChain) Switches the wallet to the specified Ethereum chain. ### [wallet\_watchAsset](/sdks/base-account/reference/core/provider-rpc-methods/wallet_watchAsset) Requests that the user track the token in their wallet. ## Advanced Methods ### [eth\_getTransactionByBlockHashAndIndex](/sdks/base-account/reference/core/provider-rpc-methods/eth_getTransactionByBlockHashAndIndex) Returns information about a transaction by block hash and transaction index position. ### [eth\_getTransactionByBlockNumberAndIndex](/sdks/base-account/reference/core/provider-rpc-methods/eth_getTransactionByBlockNumberAndIndex) Returns information about a transaction by block number and transaction index position. ### [eth\_getUncleCountByBlockHash](/sdks/base-account/reference/core/provider-rpc-methods/eth_getUncleCountByBlockHash) Returns the number of uncles in a block by block hash. ### [eth\_getUncleCountByBlockNumber](/sdks/base-account/reference/core/provider-rpc-methods/eth_getUncleCountByBlockNumber) Returns the number of uncles in a block by block number. ### [web3\_clientVersion](/sdks/base-account/reference/core/provider-rpc-methods/web3_clientVersion) Returns the current client version. ## Error Handling All RPC methods can throw errors. Common error codes include: * `-32700`: Parse error * `-32600`: Invalid request * `-32601`: Method not found * `-32602`: Invalid params * `-32603`: Internal error * `-32000`: Server error ```javascript theme={null} try { const result = await provider.request({ method: 'eth_getBalance', params: ['0x1234...', 'latest'] }); } catch (error) { console.error('RPC Error:', error.code, error.message); } ``` ## Best Practices 1. **Always handle errors**: RPC calls can fail for various reasons 2. **Use appropriate block parameters**: `latest`, `earliest`, `pending`, or specific block numbers 3. **Validate addresses**: Ensure addresses are properly formatted 4. **Cache responses**: Some data doesn't change frequently 5. **Use batch requests**: When supported, batch multiple calls for efficiency ## Compatibility Base Account maintains full compatibility with: * Web3.js * Ethers.js * Wagmi * Viem * Other standard web3 libraries All standard RPC methods work exactly as expected, ensuring your existing applications can integrate with Base Account without modification.
