​

DAS API (Digital Asset Standard)

Query NFTs, compressed NFTs, fungible tokens, and other digital assets with a unified interface.

helius.rpc().get_asset(GetAsset { id, .. })                              // Single asset by mint
helius.rpc().get_asset_batch(GetAssetBatch { ids, .. })                  // Multiple assets
helius.rpc().get_assets_by_owner(GetAssetsByOwner { owner_address, .. }) // Assets by wallet
helius.rpc().get_assets_by_authority(GetAssetsByAuthority { .. })        // Assets by update authority
helius.rpc().get_assets_by_creator(GetAssetsByCreator { .. })            // Assets by creator
helius.rpc().get_assets_by_group(GetAssetsByGroup { .. })                // Assets by collection
helius.rpc().search_assets(SearchAssets { .. })                          // Flexible search
helius.rpc().get_asset_proof(GetAssetProof { id })                       // Merkle proof (cNFTs)
helius.rpc().get_asset_proof_batch(GetAssetProofBatch { ids })           // Batch Merkle proofs
helius.rpc().get_token_accounts(GetTokenAccounts { .. })                 // Token accounts
helius.rpc().get_nft_editions(GetNftEditions { .. })                     // Print editions
helius.rpc().get_signatures_for_asset(GetAssetSignatures { id, .. })     // Transaction history for asset

​

RPC V2 Methods

Enhanced RPC methods with server-side pagination, filtering, and auto-paginating variants.

helius.rpc().get_transactions_for_address(address, options)              // Transaction history (pagination_token)
helius.rpc().get_program_accounts_v2(program_id, config)                 // Program accounts (pagination_key)
helius.rpc().get_all_program_accounts(program_id, config)                // Auto-paginating variant
helius.rpc().get_token_accounts_by_owner_v2(owner, filter, config)       // Token accounts v2 (pagination_key)
helius.rpc().get_all_token_accounts_by_owner(owner, filter, config)      // Auto-paginating variant
helius.rpc().get_priority_fee_estimate(request)                          // Fee estimates

​

Smart Transactions and Helius Sender

Build and send optimized transactions with automatic compute unit estimation, priority fees, and multi-region routing.

helius.send_smart_transaction(config)                                    // Auto-optimized send
helius.create_smart_transaction(config)                                  // Build without sending
helius.create_smart_transaction_with_seeds(config)                       // Thread-safe (seed-based)
helius.send_smart_transaction_with_seeds(config, send_opts, timeout)     // Thread-safe send
helius.send_smart_transaction_with_sender(config, sender_opts)           // Build + send via Sender
helius.create_smart_transaction_with_tip_for_sender(config, tip)         // Build with tip
helius.send_and_confirm_via_sender(tx, last_block, sender_opts)          // Send pre-built tx via Sender
helius.determine_tip_lamports(swqos_only)                                // Calculate tip amount
helius.fetch_tip_floor_75th()                                            // Get Jito tip floor
helius.warm_sender_connection(region)                                    // Warm connection via /ping
helius.get_compute_units(instructions, payer, lookup_tables, signers)    // Simulate CU usage
helius.poll_transaction_confirmation(signature)                          // Poll confirmation status

​

Enhanced Transactions

Parse raw transactions into human-readable, labeled formats.

helius.parse_transactions(ParseTransactionsRequest { transactions })     // Parse by signatures
helius.parsed_transaction_history(ParsedTransactionHistoryRequest { .. })// Parse by address

​

Webhooks

Create and manage real-time HTTP POST notifications for on-chain events.

helius.create_webhook(CreateWebhookRequest { .. })                       // Create webhook
helius.get_webhook_by_id(webhook_id)                                     // Get webhook config
helius.get_all_webhooks()                                                // List all webhooks
helius.edit_webhook(EditWebhookRequest { .. })                           // Update webhook
helius.delete_webhook(webhook_id)                                        // Delete webhook
helius.append_addresses_to_webhook(webhook_id, &addresses)               // Add monitored addresses
helius.remove_addresses_from_webhook(webhook_id, &addresses)             // Remove monitored addresses

​

Wallet API

Query wallet balances, transaction history, transfers, and identity information via REST endpoints.

helius.get_wallet_identity(wallet)                                       // Identity info
helius.get_batch_wallet_identity(&addresses)                             // Batch identity (max 100)
helius.get_wallet_balances(wallet, page, limit, zero_bal, native, nfts)  // Token balances
helius.get_wallet_history(wallet, limit, before, after, tx_type, token_accts)  // Transaction history
helius.get_wallet_transfers(wallet, limit, cursor)                       // Transfer history
helius.get_wallet_funding_source(wallet)                                 // Funding source

​

Staking

Stake SOL to the Helius validator and manage stake accounts.

helius.create_stake_transaction(owner, amount_sol)                       // Create + delegate stake
helius.create_unstake_transaction(owner, stake_account)                  // Deactivate stake
helius.create_withdraw_transaction(owner, stake_acct, dest, lamports)    // Withdraw
helius.get_stake_instructions(owner, amount_sol)                         // Get raw instructions + keypair
helius.get_unstake_instruction(owner, stake_account)                     // Deactivate instruction
helius.get_withdraw_instruction(owner, stake_acct, dest, lamports)       // Withdraw instruction
helius.get_withdrawable_amount(stake_account, include_rent_exempt)       // Check withdrawable balance
helius.get_stake_accounts(wallet)                                        // List stake accounts

​

Embedded Solana Client

Access the underlying Solana RPC clients for standard operations.

helius.connection()                  // Sync SolanaRpcClient (Arc)
helius.async_connection()?           // Async SolanaRpcClient (requires new_async)
helius.ws()                          // Enhanced WebSocket (Option)

// Standard Solana RPC via embedded client
let balance = helius.connection().get_balance(&pubkey)?;
let async_client = helius.async_connection()?;
let balance = async_client.get_balance(&pubkey).await?;
