The SDK exposes get*Tx() helpers for every write action. Use them when your app wants the SDK to build the correct calldata, but your wallet or Safe flow will handle signing and submission.

​
Available methods

  • getSetupGaslessDelegationTx()
  • getApproveUsdcTx(amount)
  • getSetDelegateTx(delegateAddress)
  • getRemoveDelegateTx()
  • getOpenTradeTx(params)
  • getCloseTradeTx(params)
  • getCancelOrderTx(params)
  • getModifyOrderTx(params)
  • getUpdateCollateralTx(params)

​
Return shape

Depending on the mode, the SDK returns one of two request types: 
type BuiltTxRequest =
  | {
      kind: 'eoa';
      to: `0x${string}`;
      data: `0x${string}`;
      value: bigint;
      from: `0x${string}`;
      traderAddress: `0x${string}`;
    }
  | {
      kind: 'safe';
      safeAddress: `0x${string}`;
      traderAddress: `0x${string}`;
      calls: [
        {
          to: `0x${string}`;
          data: `0x${string}`;
          value: bigint;
        },
      ];
    };

​
Example

const client = await OstiumClient.createSelfAndSelf({
  traderAddress: '0xTraderAddress',
});

const tx = client.getOpenTradeTx({
  pairId: 0,
  buy: true,
  price: '65000',
  collateral: '100',
  leverage: '5',
  type: OrderType.Market,
});
Use createSelfAndSelf() or createDelegatedAndSelf() for EOA-style build output, and use createSelfAndGasless() or createDelegatedAndGasless() for Safe-style build output.
