@waterx/perp-sdk

TypeScript SDK for the WaterX perpetual protocol on Sui: build PTBs with gRPC (@mysten/sui), run read-only simulateTransaction queries, and optional Pyth helpers.

ABI note: PTB entry points follow contracts/waterx_perp in this repo. Read-only view::* helpers resolve the module package from each shared object’s on-chain type (so Market / WlpPool can sit on a newer publish than GlobalConfig / AccountRegistry). BCS layouts for MarketSummary, PositionInfo, and TokenPoolSummary match the deployed view structs (see contracts/waterx_perp/package_summaries/waterx_perp/view.json). Pin WaterXConfig to your environment’s package and object IDs.

Install & build

pnpm install
pnpm build

Consumers:

pnpm add @waterx/perp-sdk @mysten/sui

Breaking changes (WLP high-level builders)

buildMintWlpTx and buildSettleRedeemWlpTx are async and return Promise<Transaction> (they resolve deposit / redeem coin oracle wiring). Callers must await:

const tx = await buildMintWlpTx(client, params);
const tx2 = await buildSettleRedeemWlpTx(client, { requestId: 1n });

Size calculation requires explicit price

buildOpenPositionTx and buildPlaceOrderTx no longer fall back to hardcoded prices when computing position size from leverage. You must provide either size (exact) or approxPrice (USD price for leverage math). Omitting both throws.

Naming: collateral on an open position

Move entry points are deposit_collateral_request / withdraw_collateral_request. The SDK exposes depositCollateral / withdrawCollateral as the preferred names; increaseCollateral / releaseCollateral remain as deprecated aliases (same parameters). High-level helpers: buildDepositCollateralTx / buildWithdrawCollateralTx (deprecated: buildIncreaseCollateralTx / buildReleaseCollateralTx).

Withdraw paths take collateralAmount for the size to pull from margin; amount is a deprecated alias (if both are passed, collateralAmount wins).

UserAccount address in PTB params

Trading (openPosition, closePosition, …), account helpers (depositToAccount, delegates, …), high-level build*Tx, and orders (placeOrder, cancelOrder) all use accountObjectAddress: the UserAccount object id (hex). Trading paths pass it as tx.pure.address; registry calls use tx.pure.id. It is not a numeric registry index.

getAccountsByOwner returns accountObjectAddress on each AccountInfo row.

High-level build*Tx helpers also accept optional collateralTokenType (defaults to WaterXConfig.usdcType). Only token types wired in resolveTokenPriceFeed (src/tx-builders.ts) get automatic Pyth updates; extend there when the protocol adds collaterals.

---

Initialize the client

All network I/O uses gRPC (SuiGrpcClient). Trading helpers require bucketFrameworkPackageId (Bucket bucket_v2_framework package) so the PTB can call account::request.

Testnet (built-in constants):

import { WaterXClient } from "@waterx/perp-sdk";

const client = WaterXClient.testnet();
// optional: custom fullnode gRPC URL
// const client = WaterXClient.testnet({ grpcUrl: "https://fullnode.testnet.sui.io:443" });

Custom config (any network):

import { WaterXClient, createTestnetConfig, type WaterXConfig } from "@waterx/perp-sdk";

const config: WaterXConfig = {
  ...createTestnetConfig(),
  packageId: "0x...", // your deployed waterx_perp package
  globalConfig: "0x...",
  // ...all other object IDs and token type strings
};
const client = new WaterXClient(config);

Examples

Read-only: pool summary & WLP metrics

Uses gRPC simulateTransaction + BCS (no signer).

import { WaterXClient, getPoolSummary, getWlpTotalSupply, getWlpTvlUsd } from "@waterx/perp-sdk";

const client = WaterXClient.testnet();

const pool = await getPoolSummary(client);
console.log("LP supply (raw):", pool.totalLpSupply.toString());
console.log("TVL (u128):", pool.tvlUsd.toString());

const supply = await getWlpTotalSupply(client);
const tvl = await getWlpTvlUsd(client);

Read-only: accounts & position

import {
  WaterXClient,
  getAccountsByOwner,
  getPosition,
  positionExists,
} from "@waterx/perp-sdk";

const client = WaterXClient.testnet();
const owner = "0x..."; // Sui address

const accounts = await getAccountsByOwner(client, owner);
const accountObjectAddress = accounts[0]!.accountObjectAddress;

const market = client.config.btcMarket;
const has = await positionExists(client, market, 0n);
if (has) {
  const pos = await getPosition(client, market, 0n);
  // `accountObjectAddress` = on-chain `user_address`; `marketIndex` = pool row index (not Market object id).
  console.log(pos.accountObjectAddress, pos.marketIndex, pos.sizeAmount);
}

High-level PTB: open position (Pyth + testnet IDs wired in)

Returns a Transaction you sign and execute with the same client.

import { WaterXClient, buildOpenPositionTx } from "@waterx/perp-sdk";
import { Ed25519Keypair } from "@mysten/sui/keypairs/ed25519";

const client = WaterXClient.testnet();
// Use your own keypair or any @mysten/sui Signer (e.g. wallet adapter).
const keypair = Ed25519Keypair.generate();

const tx = await buildOpenPositionTx(client, {
  accountObjectAddress: "0x...", // UserAccount object id (hex), not a numeric id
  base: "BTC",
  isLong: true,
  leverage: 10,
  collateralAmount: 1_000_000_000n, // 1000 USDC if 6 decimals
  approxPrice: 95_000, // required when `size` is not provided
});

const result = await client.signAndExecuteTransaction({
  transaction: tx,
  signer: keypair,
});
console.log(result.digest);

Low-level PTB: same flow, your oracle wiring

Create a Transaction, append Pyth / aggregator calls (updatePythPrices, buildPythRuleFeedCalls from this package — mirror src/tx-builders.ts), then call openPosition(client, tx, openPositionParams) (or any other builder in src/user/). Params are typed as OpenPositionParams, ClosePositionParams, etc.

API overview

Core

Export	Purpose
WaterXClient	gRPC client, simulate(), signAndExecuteTransaction()
createTestnetConfig()	Default testnet package/object/token IDs + Pyth config
WaterXConfig	Full config; must include bucketFrameworkPackageId for trading PTBs

Transaction builders (append to Transaction)

Group	Functions
Shared	accountSenderRequest(tx, client)
Trading	openPosition, closePosition, increasePosition, decreasePosition, depositCollateral, withdrawCollateral (increaseCollateral / releaseCollateral deprecated), liquidate, matchOrders, updateFundingRate
Orders	placeOrder, cancelOrder
WLP	mintWlp, requestRedeemWlp, cancelRedeemWlp, settleRedeemWlp
Account	createAccount, depositToAccount, receiveCoin, transferAccount, addDelegate, removeDelegate, updateDelegatePermissions
Referral	setReferralCode, useReferralCode, registerReferralCode, bindReferral

Param types: OpenPositionParams, IncreasePositionParams, DecreasePositionParams, etc. (see src/index.ts).

Read-only queries (simulate + BCS)

Area	Functions
Account	getAccountsByOwner, getAccountDelegates, getAccountObjectId (deprecated — use accountObjectAddress directly), getAccountCoins, getAccountBalance, selectCoinsForAmount
Market / pool	getMarketSummary (view::market_summary<LP> — optional typeArgs: LP type string or { lpTokenType? } only), getPoolSummary, getWlpTotalSupply, getWlpTvlUsd, getTokenPoolSummary
Position	getPosition, positionExists (same LP type-arg rules as getMarketSummary)

View return shapes: MarketSummary includes marketIndex (on-chain index). PositionInfoView exposes marketIndex (bigint) and accountObjectAddress (from user_address). getTokenPoolSummary maps TokenPoolSummary.lastPriceRefreshTimestamp when the return payload includes it; older 72-byte deployments surface 0n (see parseTokenPoolSummaryReturn in fetch.ts).

High-level PTB helpers

buildOpenPositionTx, buildClosePositionTx, buildIncreasePositionTx, buildDecreasePositionTx, buildDepositCollateralTx, buildWithdrawCollateralTx (buildIncreaseCollateralTx / buildReleaseCollateralTx deprecated), buildPlaceOrderTx, buildCancelOrderTx (all async, Pyth-backed). buildMintWlpTx and buildSettleRedeemWlpTx are also async (deposit / redeem coin oracle). buildRequestRedeemWlpTx (requires recipient), buildCancelRedeemWlpTx.

Constants & Pyth

Permission bits, order tags, testnet IDs, Pyth feeds: src/constants.ts.
On testnet, TESTNET_TYPES.WLP is the LP type wired to the live WlpPool / Market (wlp_token::WLP_TOKEN); TESTNET_PACKAGE_IDS.WLP_STANDALONE points at the standalone contracts/wlp publish for reference.
Oracle wiring: fetchPriceFeedsUpdateData, updatePythPrices, buildPythRuleFeedCalls, PythCache, etc. in src/utils/pyth.ts.
