Avalanche RPC
How to use it
// yarn add @tatumio/tatum
import { TatumSDK, AvalancheC, Network } from '@tatumio/tatum'
const tatum = await TatumSDK.init<AvalancheC>({ network: Network.AVALANCHE_C })
const result = await tatum.rpc.getProof(
'0x5377CAF64CF02c1320c66030fbe3773431377daC',
['0x0000000000000000000000000000000000000000000000000000000000000000'],
'latest',
)
await tatum.destroy() // Destroy Tatum SDK - needed for stopping background jobs
Overview
The eth_getProof
is a JSON-RPC method that retrieves the Merkle-Patricia proof for an account, storage key-value pairs, and account transaction count. It allows developers to verify the state of an account or storage value at a specific block without needing the entire state trie. This method is particularly useful for light clients or off-chain applications that require proof of an account's state or specific storage values.
Parameters
address
-Data
, 20 Bytes- The address of the account.
- Example:
"0x5377CAF64CF02c1320c66030fbe3773431377daC"
keys
-Array
ofData
- An array of storage keys for which the proof should be generated.
- Example:
["0x0000000000000000000000000000000000000000000000000000000000000000"]
blockNumber
-Quantity
orString
- The block number for which the proof should be generated.
- Example:
"0x1"
or"latest"
Return Object
The method returns an object containing the following fields:
accountProof
-Array
ofData
- The serialized Merkle-Patricia proof for the account.
balance
-Quantity
- The balance of the account at the specified block.
codeHash
-Data
, 32 Bytes- The hash of the code for the account at the specified block.
nonce
-Quantity
- The transaction count of the account at the specified block.
storageProof
-Array
ofObject
- An array of storage proof objects, one for each requested key, containing the following fields:
key
-Data
, 32 Bytes: The storage key.value
-Quantity
: The storage value.proof
-Array
ofData
: The serialized Merkle-Patricia proof for the key-value pair.
- An array of storage proof objects, one for each requested key, containing the following fields:
