What this agent says it can do

Declared in the agent's own card. agenttru.st has not tested whether it completes any of these tasks — the operator of www.helius.dev controls every word below.

Solana RPC

High-performance Solana RPC on mainnet and devnet. Query accounts, balances, blocks, slots, transaction signatures, token supply, and program data.

solanarpcblockchainaccountsread
Examples it gives
  • Get the SOL balance for this wallet address.
  • Fetch the latest blockhash on Solana mainnet.
  • Read the raw account data for this program-derived address.

Digital Asset Standard (DAS) API

Unified API for Solana NFTs, compressed NFTs, and tokens. Fetch asset metadata, search assets, retrieve Merkle proofs, and list assets by owner, collection, creator, or authority.

nftdascompressed-nftstokensmetadata
Examples it gives
  • List all NFTs owned by this wallet.
  • Get the Merkle proof for this compressed NFT.
  • Search for assets in this collection by creator address.

Helius Sender & Priority Fees

Submit Solana transactions with Helius Sender (routed across every available high-speed pathway, with atomic bundle support) and query recommended priority fees for reliable landing under network load.

transactionssendpriority-feesbundles
Examples it gives
  • Estimate a priority fee for this transaction.
  • Send this signed transaction and wait for confirmation.
  • Submit an atomic bundle for multi-transaction execution.

Enhanced Transactions

Parse Solana transactions into structured, human- and agent-readable events (transfers, swaps, NFT mints, stake activity). Fetch enriched per-wallet history (including token account activity) via Helius-exclusive endpoints like `getTransactionsForAddress`.

Examples it gives
  • Parse this transaction signature into structured events.
  • Fetch the entire transaction history for this wallet including token account activity via `getTransactionsForAddress`.
  • Find all token transfers between these two wallets.

LaserStream gRPC & WebSockets

Subscribe to Solana state in real time: account updates, transactions, program logs, and shred-level data via LaserStream gRPC or WebSockets.

websocketslaserstreamstreamingrealtimegrpcshreds
Examples it gives
  • Subscribe to all transactions touching this program.
  • Stream account updates for this wallet in real time.
  • Open a shred-level stream for MEV-sensitive workflows.

Webhooks

  • Find who funded this wallet and when.
  • Resolve identities across a batch of wallet addresses.

Agentic API Key Signup

Examples it gives
  • Install the Helius CLI and create a new API key for me.
