helius_execute_jupiter_swap
Execute a token swap using Jupiter
LABSCO SUMMARY
Broad Solana read access, with key custody left outside the server.
The tools that change chain state are helius_send_jito_bundle and helius_execute_jupiter_swap; everything else reads and hands back what the Helius endpoint returned. Both write paths keep the sensitive part with you — one takes a signer, the other takes transactions you serialized yourself. Asset coverage runs through the Helius asset endpoints rather than raw RPC, which is what makes by-creator, by-authority and by-group queries possible at all.
What it is
A Solana RPC and digital-asset gateway over the Helius API, 38 tools deep across chain reads, asset lookups, fee estimation and transaction submission.
What you get
- Account state for any address: SOL balance, raw account info, several accounts in one call, and every account owned by a program.
- Token positions and supply — token accounts by owner or by mint, the largest holders of a mint, and the balance of a single token account.
- Chain status reads: current slot, block height, latest blockhash, epoch info and schedule, leader schedule, node version and recent performance samples.
- Digital-asset lookups by id, by owner, by creator, by authority and by group, plus a filtered asset search, NFT editions, asset proofs and real-world-asset records.
- Transaction work — signature history for an address, a transaction by signature, fee for a serialized message, priority-fee estimates and confirmation polling.
- Submission paths beyond plain RPC: helius_send_jito_bundle with helius_get_bundle_statuses, and helius_execute_jupiter_swap for a token swap.
Requirements
A Helius API key in HELIUS_API_KEY. Signing stays on your side: helius_execute_jupiter_swap takes a signer, and helius_send_jito_bundle takes transactions you have already serialized.

USE CASES
01
Auditing what a Solana address actually holds
Pull the SOL balance, the token accounts and the digital assets attributed to one owner, then open the raw account record when the numbers disagree.
02
Tracing a transfer a user says never arrived
Walk back from the address to its recent signatures, open the transaction that matters, and poll until the network reports a confirmation status.
03
Pricing a transaction before you submit it
Estimate what the network will charge for the accounts being touched and confirm the fee on the exact message you plan to send.
04
Vetting an NFT before you buy into the collection
Check the asset record itself, who created it, how many editions exist and what has happened to it, instead of trusting the listing page.
05
Getting a bundle through Jito and confirming it settled
Submit already-serialized transactions as a bundle to a Jito endpoint, then read back the status of the bundle ids you were handed.
06
Working out whether the cluster is keeping up before you blame your code
Read the current slot, block height and epoch position alongside recent performance samples and the node version.

BEFORE YOU INSTALL
What to know first
Tools you get
38 tools when we connected. helius_send_jito_bundle and helius_execute_jupiter_swap move real value on mainnet, and no read-only mode is documented. helius_get_token_largest_accounts is available but missing from the documentation.
Requires
- npx on PATH
- Node.js
- HELIUS_API_KEY in your environment
Where it runs
The documented client runs the server on your machine.
