The EffectStream presale launchpad already handles Cardano L1 payments. This post covers what comes next: a commitment-based presale that settles on Midnight - a Cardano Partner Chain where every block is validated by Cardano SPOs - and lets buyers reserve a spot in multiple campaigns at the same time without locking their funds for any of them.
This is part two of a two-part series on building a presale on Cardano. Part one covered the on-chain contract - how a purchase receipt is enforced so a participation is only recorded if the buyer really paid. This post is about the app on top of it.
Standing up a presale used to mean wiring a sale contract, an indexer, a payment flow, and a UI before you could take a single order. With the EffectStream preorder launchpad, creating a campaign on Cardano comes down to two steps: clone and publish. This post walks through the app built on top of that contract - and the piece that makes the Cardano side genuinely fast: UTxORPC.
NFT launches are complicated. Creators need smart contracts for the sale, a UI for buyers, multi-chain payment support, proof of participation, and fulfillment tracking. We built a full launchpad platform that handles all of this, with EffectStream powering the backend state management and cross-chain payment processing.
