I’m happy to share a new tutorial that I’ve been working on for some time. This is a step-by-step recipe (with some sample artifacts) to show off various parts of our ecosystem, letting you build and deploy a working web app from the allowance contract allowance.simf, and interact with it using a real Liquid wallet.
(You may have seen this contract on our developer docs landing page. It’s a covenant example that lets a benefactor create an allowance that a beneficiary can draw upon, but only a certain amount of money per time period.)
As of late October 2026, the main rough edges I know of are: (1) you have to apply a few source patches, (2) you have to compile the Humid Wallet from source code yourself, (3) the versions of txmanifest.json used in different steps reflect different versions of the txmanifest specification.
In general, this tutorial should be able to take you through the whole process and end up with a working web app of your own, doing Liquid testnet transactions from a real wallet and checking the status of contract deployments with a linked web app, in addition to writing Simplex integration tests.
I’d be glad to hear about your experiences trying it out!
