Swig Developer SDK

Server-side SDKs for the hosted Swig wallet API. The Swig API prepares wallet transactions; your application signs and submits them.

Canonical source: https://github.com/anagrambuild/swig-developer-sdk

Package	Language	Version	Directory
@swig-wallet/developer-sdk	TypeScript	0.9.0	typescript
swig-developer-sdk	Python	0.8.0	python

Both packages target the public API base URL https://api.onswig.com.

The prepare-first boundary

1. Your server creates a client with an API key.
2. Your server prepares a wallet operation and receives one or more unsigned transactions.
3. Your application obtains every required signature outside the server SDK.
4. Your app submits them directly, or through Swig's paymaster sponsorship.

API keys stay on the server. Send prepared transactions to your application-owned signer, then return the signed transactions to the server for sponsorship or submission.

TypeScript signs with @solana/web3.js; Python signs with solders. Neither package sends signing material to the API.
