RallyTransact's gasless transactions can be utilized outside of the RallyMobile SDK such as from a backend, web dapp, desktop, etc. Submitting transactions to RallyTransact is a 2 step process:
Sign a transaction on the client (web, backend, etc)
Create a HTTP request containing a JSON payload with details about the transaction you'd like to relay.
An API key is required to use the infrastructure to power gasless transactions. Visit to generate both Amoy and Mainnet Polygon API keys.
Our hosted transaction infrastructure honors the interface with the addition of an authentication HTTP header containing your API key. If you're already using a GSN client the following steps should be all you need to change:
Set https://api.rallyprotocol.com
as your relay URL.
Add the following header to the HTTP request Authorization: Bearer <YOUR_API_TOKEN>
Examples coming soon. Reach out to us on and we'll happily walk you through it
