Integration Examples

Setup

All examples use this shared setup:

import { Connection, Keypair, PublicKey } from "@solana/web3.js";
import {
  SymmetryCore,
  KeeperMonitor,
  RebalanceHandler,
  getJupTokenLedgerAndSwapInstructions,
  getSwapPairs,
  isRebalanceRequired,
} from "@symmetry-hq/sdk";

function createWallet(keypair: Keypair) {
  return {
    publicKey: keypair.publicKey,
    signTransaction: async <T>(tx: T): Promise<T> => {
      (tx as any).sign([keypair]);
      return tx;
    },
    signAllTransactions: async <T>(txs: T[]): Promise<T[]> => {
      txs.forEach((tx: any) => tx.sign([keypair]));
      return txs;
    },
    payer: keypair,
  };
}

const connection = new Connection("https://api.mainnet-beta.solana.com");
const keypair = Keypair.fromSecretKey(/* your secret key bytes */);
const wallet = createWallet(keypair);

const sdk = new SymmetryCore({
  connection,
  network: "mainnet",
  priorityFee: 50_000,
});

Examples work with both SPL and Token Extensions (Token22) mints where token mint inputs are used.

Create a Vault with Tokens

Creates a 2-token vault with SOL (50%) and USDC (50%). The metadata_uri must point to a JSON file with the vault’s metadata. The JSON should contain at minimum name, symbol, description, image, and cover fields. You can add any extra fields (website, social links, etc.) for your own integrations to consume. Example metadata JSON at the URI:

{
  "name": "Diversified Index",
  "symbol": "DIVX",
  "description": "A diversified vault tracking SOL, USDC, and other tokens.",
  "image": "https://arweave.net/your-token-image-url",
  "cover": "https://arweave.net/your-cover-image-url"
}

const vaultResult: VaultCreationTx = await sdk.createVaultTx({
  creator: wallet.publicKey.toBase58(),
  start_price: "1.0",

  symbol: "DIVX",

    host_deposit_fee_bps: 10,
    host_withdraw_fee_bps: 10,
    host_management_fee_bps: 0,    // currently disabled in global config

const rebalanceIntents: UIRebalanceIntent[] = await sdk.fetchVaultRebalanceIntents(VAULT_PUBKEY);

for (const ri of rebalanceIntents) {
  const data: FormattedRebalanceIntent = ri.formatted_data;
  console.log(`Intent: ${data.pubkey}`);
  console.log(`  Type: ${data.rebalance_type}`);
  console.log(`  Action: ${data.current_action}`);
  console.log(`  Owner: ${data.owner}`);

  if (ri.deposit_data) {
    console.log(`  Deposits:`);
    for (const token of ri.deposit_data.tokens) {
      console.log(`    ${token.mint}: ${token.amount}`);
    }
  }

  if (ri.auction_data) {
    console.log(`  Auction stages:`);
    for (const stage of ri.auction_data.auction_stages) {
      console.log(`    ${new Date(stage.start_time * 1000).toISOString()} - ${new Date(stage.end_time * 1000).toISOString()}`);
    }
  }
}

const tx = await sdk.addBountyTx({
  keeper: wallet.publicKey.toBase58(),
  vault: "<VAULT_PUBKEY>",
  amount: 100_000_000,
});

await sdk.signAndSendTxPayloadBatchSequence({
  txPayloadBatchSequence: tx,
  wallet,
});

Build a Portfolio Tracker

async function getPortfolio(ownerPubkey: string) {
  const allVaults = await sdk.fetchAllVaults();
  const portfolio = [];

  for (const vault of allVaults) {
    const pricedVault = await sdk.loadVaultPrice(vault);
    const vaultMint = pricedVault.mint.toBase58();

    portfolio.push({
      name: pricedVault.formatted!.name,
      symbol: pricedVault.formatted!.symbol,
      mint: vaultMint,
      price: pricedVault.price?.toNumber(),
      tvl: pricedVault.tvl?.toNumber(),
      composition: pricedVault.formatted!.composition
        .filter(a => a.active)
        .map(a => ({
          mint: a.mint,
          weight: a.weight / 100,
          amount: a.amount,
        })),
    });

Common Patterns

Error Handling

try {
  const tx = await sdk.buyVaultTx({ /* ... */ });
  const sigs = await sdk.signAndSendTxPayloadBatchSequence({
    txPayloadBatchSequence: tx,
    wallet,
  });
  console.log("Success:", sigs);
} catch (error) {
  console.error("Transaction failed:", error);
}

Preflight Mode

simulateTransactions: true enables a preflight-style send path in the SDK — it does not perform offline-only simulation. Transactions are still sent to the network. Do not use on production keys if you expect zero chain side-effects.

const sigs = await sdk.signAndSendTxPayloadBatchSequence({
  txPayloadBatchSequence: tx,
  wallet,
  simulateTransactions: true,
});

Working with Amounts

Token amounts are always in the smallest unit (lamports):

Token	Decimals	1 token =
SOL	9	1,000,000,000 lamports
USDC	6	1,000,000
General	N	`rawAmount = humanAmount * 10^N`

This applies to contributions[].amount, withdraw_amount, amount_in, amount_out, bounty amount, min_bounty_amount, and max_bounty_amount.

Vault Mint vs Vault Account

Two addresses are associated with each vault:

Vault mint (vault.mint): The token mint of the vault token. Used in buyVaultTx, sellVaultTx, rebalanceVaultTx.
Vault account (vault.ownAddress or vault.formatted.pubkey): The on-chain state account. Used in fetchVault, addOrEditTokenTx, editFeesTx, etc.

To go from mint → account: getVaultState(mintPubkey) (PDA derivation). To go from account → mint: read vault.mint from the fetched vault.
