Choose an SDK Language - Swig

TypeScript and Python expose the same prepare-first server model. Choose the language that owns your trusted application runtime.

TypeScript

import { SwigClient } from '@swig-wallet/developer-sdk';

const swig = new SwigClient({
  apiKey: process.env.SWIG_API_KEY!,
  network: 'devnet',
});

Install from npm with bun add @swig-wallet/developer-sdk. Import the API-key client from the package root. Application-owned signing helpers are available from @swig-wallet/developer-sdk/signers.

Python

import os

from swig_developer_sdk import SwigClient

swig = SwigClient(
    api_key=os.environ["SWIG_API_KEY"],
    network="devnet",
)

Install from PyPI with pip install swig-developer-sdk. Python exposes signing helpers from the package root.

Comparison

Capability	TypeScript	Python
Wallet preparation	yes	yes
Wallet reads and ramp	yes	yes
Custom transactions	yes	yes
Sponsorship	yes	yes
Application-owned signing helpers	`/signers`	package root

Both SDKs expose the full server surface: preparation, custom transactions, wallet reads, ramp, paymaster balance, and sponsorship. Your application owns its HTTP routes, authentication, authorization, validation, and response format.
