Struct SolanaClient 

pub struct SolanaClient { /* private fields */ }

Solana blockchain client.

Supports balance queries via JSON-RPC and optional transaction history via Solscan API.

Implementations

impl SolanaClient

pub fn new(config: &ChainsConfig) -> Result<Self>

👎Deprecated since 0.8.0:

pass the transport: use SolanaClient::new_with_http

Creates a new Solana client with the given configuration.

Arguments

• config - Chain configuration containing RPC endpoint and API keys

Returns

Returns a configured SolanaClient instance.

Examples

use scope::chains::SolanaClient;
use scope::config::ChainsConfig;

let config = ChainsConfig::default();
let client = SolanaClient::new(&config).unwrap();

pub fn new_with_http( config: &ChainsConfig, http: Arc<dyn HttpClient>, ) -> Result<Self>

Creates a new Solana client with a pre-built HTTP transport.

pub fn with_rpc_url(rpc_url: &str) -> Self

Creates a client with a custom RPC URL.

Arguments

• rpc_url - The Solana JSON-RPC endpoint URL

pub fn chain_name(&self) -> &str

Returns the chain name.

pub fn native_token_symbol(&self) -> &str

Returns the native token symbol.

pub async fn get_balance(&self, address: &str) -> Result<Balance>

Fetches the SOL balance for an address.

Arguments

• address - The Solana address (base58 encoded)

Returns

Returns a Balance struct with the balance in multiple formats.

Errors

Returns ScopeError::InvalidAddress if the address format is invalid. Returns ScopeError::Request if the API request fails.

pub async fn get_token_info(&self, mint_address: &str) -> Result<Token>

Fetches SPL token (mint) info from RPC.

Parses decimals from the mint account data. Symbol and name use placeholders (Solscan Pro API would provide full metadata).

pub async fn enrich_balance_usd(&self, balance: &mut Balance)

Enriches a balance with a USD value using DexScreener price lookup.

pub async fn get_token_balances( &self, address: &str, ) -> Result<Vec<TokenBalance>>

Fetches all SPL token balances for an address.

Arguments

• address - The Solana wallet address to query

Returns

Returns a vector of TokenBalance containing all SPL tokens held by the address.

Errors

Returns ScopeError::InvalidAddress if the address format is invalid. Returns ScopeError::Request if the API request fails.

pub async fn get_signatures( &self, address: &str, limit: u32, ) -> Result<Vec<String>>

Fetches recent transaction signatures for an address.

Arguments

• address - The Solana address to query
• limit - Maximum number of signatures to return

Returns

Returns a vector of transaction signatures.

pub async fn get_transaction(&self, signature: &str) -> Result<Transaction>

Fetches transaction details by signature.

Arguments

• signature - The transaction signature (base58 encoded)

Returns

Returns Transaction details.

pub async fn get_transactions( &self, address: &str, limit: u32, ) -> Result<Vec<Transaction>>

Fetches recent transactions for an address.

Arguments

• address - The address to query
• limit - Maximum number of transactions

Returns

Returns a vector of Transaction objects.

pub async fn get_slot(&self) -> Result<u64>

Fetches the current slot number (equivalent to block number).
