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?;
