eth_getProof

The eth_getProof method returns the account and storage values of the specified account including Merkle-Patricia tree proofs on the Tron network. This method provides cryptographic proofs that allow anyone to verify account data (balance, nonce, code, storage) without needing to trust the RPC provider or run a full node.

The method is essential for building trustless applications such as light clients, cross-chain bridges, Layer 2 solutions, and state verification systems. The returned proofs can be independently verified against a known state root (from a trusted block header), enabling secure verification of account states and storage values. This is particularly valuable for applications that need to prove on-chain state to external systems or smart contracts, such as proving token balances for bridges or verifying contract storage in fraud proofs.

Parameters

parameter	type	description
address	string (required)	The Tron address to get proof for (20 bytes)
storageKeys	array (required)	Array of storage key positions to get proofs for
blockParameter	string (required)	Block number in hex or tag (latest, earliest, pending)

Return Object

The method returns an object containing account information and cryptographic proofs:

field	type	description
address	string	The address of the account (20 bytes)
balance	string	The current balance of the account in sun (hex-encoded)
codeHash	string	Hash of the account's bytecode (32 bytes). For EOAs (externally owned accounts), this is the hash of empty data
nonce	string	The transaction count/nonce for this account (hex-encoded)
storageHash	string	Hash of the storage trie root (32 bytes). Represents the root hash of the account's storage
accountProof	array	Array of RLP-encoded Merkle-Patricia tree nodes that prove the account's existence and values in the state trie. This proof can be verified against the state root from the block header
storageProof	array	Array of storage proof objects, one for each requested storage key. Each object contains: key (requested storage key), value (storage value at this key), and proof (array of RLP-encoded nodes proving this storage value)
