JSON-RPC API

Boba Network shares the same JSON-RPC API (opens new window) as Ethereum. Some new custom methods have been introduced and some other have been made unsupported for operation.
​
You can use the lightning replica node to debug your transactions.
Example
curl https://lightning-replica.boba.network/ -X POST --header 'Content-type: application/json' --data '{"jsonrpc":"2.0", "method":"debug_traceTransaction", "params":["0xf97b6fdce473b96d9cb00bb45d8fbfbc2911f383c7d525ec9d84d916cc30d347", {}], "id":1}'
​
eth_getBlockRange
DEPRECATION NOTICE
We will likely remove this method in a future release in favor of simply using batched RPC requests. If your application relies on this method, please file an issue and we will provide a migration path. Otherwise, please use eth_getBlockByNumber instead.
Like eth_getBlockByNumber but accepts a range of block numbers instead of just a single block.
Parameters
1.QUANTITY|TAG - integer of the starting block number for the range, or the string "earliest", "latest" or "pending", as in the default block parameter (opens new window).
2.QUANTITY|TAG - integer of the ending block number for the range, or the string "earliest", "latest" or "pending", as in the default block parameter (opens new window).
3.BOOLEAN - If true it returns the full transaction objects, if false only the hashes of the transactions.
Returns
An array of block objects. See eth_getBlockByHash (opens new window)for the structure of a block object.
Example
// Request
curl -X POST -H "Content-Type: application/json" --data '{"jsonrpc":"2.0","method":"eth_getBlockRange","params":["0x1", "0x2", false],"id":1}' <node url>

eth_getProof
Returns the account and storage values of the specified account including the Merkle-proof. This call can be used to verify that the data you are pulling from is not tampered with.
Parameters
1.DATA - address of the account.
2.ARRAY - array of storage-keys which should be proofed and included. See eth_getStorageAt (opens new window).
3.QUANTITY|TAG - integer of the ending block number for the range, or the string "earliest", "latest" or "pending", as in the default block parameter (opens new window).
Returns
Object
balance: QUANTITY - the balance of the account.
codeHash: DATA - hash of the code of the account. For a simple Account without code it will return "0xc5d2460186f7233c927e7db2dcc703c0e500b653ca82273b7bfad8045d85a470"
nonce: QUANTITY - nonce of the account
storageHash: DATA - SHA3 of the StorageRoot. All storage will deliver a MerkleProof starting with this rootHash.
accountProof: ARRAY - Array of rlp-serialized MerkleTree-Nodes, starting with the stateRoot-Node, following the path of the SHA3 (address) as key.
storageProof: ARRAY - Array of storage-entries as requested. Each entry is a object with these properties:
key: QUANTITY - the requested storage key
value: QUANTITY - the storage value
proof: ARRAY - Array of rlp-serialized MerkleTree-Nodes, starting with the storageHash-Node, following the path of the SHA3 (key) as path.

eth_getAccounts
This method is used to retrieve a list of addresses owned by a user. Boba Network nodes do not expose internal wallets for security reasons and therefore block the eth_getAccounts method by default. You should use external wallet software as an alternative.
eth_sendTransaction
Boba Network nodes also block the eth_sendTransaction method for the same reasons as eth_getAccounts. You should use external wallet software as an alternative. Please note that this is not the same as the eth_sendRawTransaction method, which accepts a signed transaction as an input. eth_sendRawTransaction is supported by Boba Network.
