The Overpass TypeScript SDK provides helpers for discovery, quoting, wrapper creation, deposits, withdrawals, fee claiming, and source-pool listing. The Overpass Rust SDK was built for Jupiter’s Overpass routing integration and can also be used directly by other Rust integrators. It implements Jupiter’s Amm trait for Overpass wrapper vaults. See Jupiter routing.

Install

npm install @symmetry-hq/overpass @solana/web3.js @solana/spl-token

​
Core imports

import {
  PROGRAM_ID,
  Overpass,
  OverpassLoader,
  SwapMode,
  fetchAllPools,
  loadAllWrappers,
  loadWrappersByCreator,
  loadWrappersByProtocol,
  createWrapper,
  buildOverpassSwap,
  deposit,
  withdraw,
  claimCreatorFees,
  updateCreatorFee,
} from "@symmetry-hq/overpass";

​
Program ID

import { PROGRAM_ID } from "@symmetry-hq/overpass";

console.log(PROGRAM_ID.toBase58());
Mainnet: 
WRAPdXmxrH37RKUbH1QMnYrKdNe8w4Kz44t1cXmYeum

​
List source pools

Use source-pool listing when building market discovery screens. 
const pools = await fetchAllPools(connection);

for (const pool of pools) {
  console.log(pool.protocol, pool.kind, pool.address, pool.underlyingMint);
}
Each pool includes:
  • protocol
  • kind, either lend or vault
  • address
  • underlying mint
  • mint decimals
  • deposit cap state
  • protocol-specific state

​
List yield tokens

Use wrapper listing when building token discovery screens. 
const wrappers = await loadAllWrappers(connection, {
  programId: PROGRAM_ID,
  refresh: true,
});
You can also filter by creator or protocol: 
const byCreator = await loadWrappersByCreator(connection, creator);
const byProtocol = await loadWrappersByProtocol(connection, 1);
Protocol kinds: 
enum ProtocolKind {
  Kvault = 0,
  Klend = 1,
  Save = 2,
  Lulo = 3,
  Marginfi = 4,
}

​
Refresh wrapper state

Some wrappers need fresh source accounts before quoting. 
const loader = new OverpassLoader();
await loader.refreshMany(connection, wrappers);
Then create a quote context: 
const ctx = wrapper.getQuoteContext(
  BigInt(currentSlot),
  BigInt(Math.floor(Date.now() / 1000)),
);

​
Quote

const quote = wrapper.quote(
  {
    amount: 1_000_000n,
    inputMint: wrapper.underlyingMint,
    outputMint: wrapper.wrapperMint,
    swapMode: SwapMode.ExactIn,
  },
  ctx,
);

console.log({
  outAmount: quote.outAmount,
  feeAmount: quote.feeAmount,
  warnings: quote.warnings,
});
Quotes can produce warnings. Treat warnings as route-quality signals and block execution when they indicate likely failure.

​
Build a deposit or withdrawal

const built = await buildOverpassSwap(connection, {
  user,
  wrapperMint,
  amount: 1_000_000n,
  direction: "deposit",
  minOut: 0n,
});
The returned bundle includes instructions, lookup tables, and suggested compute units. Compose it into your transaction builder or wallet flow. Convenience helpers are also available: 
const depositIx = await deposit(connection, {
  user,
  wrapperMint,
  amount,
  minOut,
});

const withdrawIx = await withdraw(connection, {
  user,
  wrapperMint,
  amount,
  minOut,
});

​
Create a wrapper

const result = await createWrapper(connection, {
  creator,
  source,
  underlyingMint,
  name,
  symbol,
  uri,
  creatorDepositFeeBps,
  initialDeposit,
});
The result includes a versioned transaction and the new wrapper mint.

​
Source constraints

Use source constraints to display minimum deposits and withdrawals. 
const constraints = await Overpass.fetchSourceConstraints(
  connection,
  source,
  "marginfi",
);
Valid source kinds are: 
kvault
klend
save
lulo
marginfi

​
Global config

const { pda, state } = await Overpass.fetchGlobalConfig(connection);

console.log(pda.toBase58(), state);
The global config includes program-wide settings such as admin, fee recipient, protocol deposit fee, and maximum creator deposit fee.
