Code Blocks to Remove/Update

1. src/types/send.ts - Remove launchtube from types

// UPDATE SendRequest interface - REMOVE launchtube field
export interface SendRequest {
  xdr: string;
  // REMOVE: launchtube?: boolean;
}

// UPDATE submissionMethod type FROM:
submissionMethod: 'soroban' | 'horizon' | 'launchtube';
// TO:
submissionMethod: 'soroban' | 'horizon';

2. src/soroswap-sdk.ts - Update send method signature

// UPDATE send method (around line 137) FROM:
async send(xdr: string, launchtube: boolean = false, network?: SupportedNetworks): Promise<SendTransactionResponse> {
  const params = { network: network || this.defaultNetwork };
  const url = this.httpClient.buildUrlWithQuery('/send', params);

  const sendData: SendRequest = { xdr, launchtube };
  return this.httpClient.post<SendTransactionResponse>(url, sendData);
}

// TO:
async send(xdr: string, network?: SupportedNetworks): Promise<SendTransactionResponse> {
  const params = { network: network || this.defaultNetwork };
  const url = this.httpClient.buildUrlWithQuery('/send', params);

  const sendData: SendRequest = { xdr };
  return this.httpClient.post<SendTransactionResponse>(url, sendData);
}

3. tests/soroswap-sdk.test.ts - Update tests

// UPDATE test (around line 286) - remove launchtube from expected request
it('should send transaction with default parameters', async () => {
  const expectedRequest: SendRequest = {
    xdr: 'SIGNED_XDR_123',
    // REMOVE: launchtube: false
  };
  // ... update test call from send(xdr, false) to send(xdr)
});

// REMOVE entire test (around line 300)
it('should send transaction with launchtube enabled', async () => {
  // DELETE THIS ENTIRE TEST
});

// UPDATE test (around line 314) - update to use new signature
it('should send transaction with specified network', async () => {
  const expectedRequest: SendRequest = {
    xdr: 'SIGNED_XDR_123',
    // REMOVE: launchtube: false
  };
  // ... update test call from send(xdr, false, network) to send(xdr, network)
});

4. README.md - Update documentation

// UPDATE line 55 FROM:
const result = await soroswapClient.send(signedXdr, false); // launchtube = false
// TO:
const result = await soroswapClient.send(signedXdr);

// UPDATE SoroswapClientConfig section (line 68) - REMOVE:
timeout?: number;  // you might want to adjust this if using launchtube
// TO:
timeout?: number;  // Request timeout in ms (defaults to 30000)

// UPDATE Send Transaction section (lines 147-152) FROM:
const result = await soroswapClient.send(
  signedXdr,           // The signed transaction XDR
  false,               // launchtube: boolean (default false)
  SupportedNetworks.MAINNET  // Optional network override
);
// TO:
const result = await soroswapClient.send(
  signedXdr,                      // The signed transaction XDR
  SupportedNetworks.MAINNET       // Optional network override
);

5. examples/backend-example.js - Update examples

// UPDATE line 84 FROM:
const sendResult = await sdk.send(signedXdr, false); // launchtube = false
// TO:
const sendResult = await sdk.send(signedXdr);

// UPDATE lines 173-175 FROM:
const { signedXdr, launchtube = false } = req.body;
const result = await sdk.send(signedXdr, launchtube);
// TO:
const { signedXdr } = req.body;
const result = await sdk.send(signedXdr);

6. llms.txt - Update LLM documentation

// UPDATE lines 97-102 FROM:
- **Method**: `send(xdr: string, launchtube: boolean = false, network?: SupportedNetworks)`
- **Parameters**:
  - `xdr`: Signed transaction XDR string
  - `launchtube`: Use launchtube for submission (optional)
  - `network`: Network override (optional)
// TO:
- **Method**: `send(xdr: string, network?: SupportedNetworks)`
- **Parameters**:
  - `xdr`: Signed transaction XDR string
  - `network`: Network override (optional)

7. CLAUDE.md - Update Claude documentation

// UPDATE line 86 - REMOVE launchtube mention:
- `timeout` - Request timeout (default 30s, consider increasing for launchtube)
// TO:
- `timeout` - Request timeout (default 30s)

Implementation Checklist

• Remove launchtube field from SendRequest interface
• Remove 'launchtube' from submissionMethod type in SendTransactionResponse
• Update send() method signature to remove launchtube parameter
• Update tests to reflect new signature
• Remove launchtube-specific test case
• Update README.md documentation
• Update examples/backend-example.js
• Update llms.txt
• Update CLAUDE.md
• Run tests to ensure everything passes
• Bump package version (breaking change)
• Update CHANGELOG with breaking change note

Breaking Change Migration

Before (deprecated):

// Using launchtube parameter
const result = await soroswapClient.send(signedXdr, true);
const result = await soroswapClient.send(signedXdr, false, SupportedNetworks.MAINNET);

After:

// All transactions go directly to Stellar network
const result = await soroswapClient.send(signedXdr);
const result = await soroswapClient.send(signedXdr, SupportedNetworks.MAINNET);

Version Bump

This is a breaking change that requires a major version bump due to:

1. Removal of launchtube parameter from send() method
2. Change in method signature (parameter order changed)
3. Removal of 'launchtube' from submissionMethod response type

Notes

• The SendTransactionResponse will continue to work, just without 'launchtube' as a possible submissionMethod value
• Clients should update their code to use the new send(xdr, network?) signature
• The API changes (soroswap/api#189) should be deployed before the SDK is published
