Thank you to the delegates for the continued engagement and thoughtful feedback. We understand the concerns around proportionality, scope, and clarity regarding what each phase of integration delivers. Based on this guidance, we are submitting a streamlined proposal composed of three clear, verifiable milestones, each producing measurable on-chain value for the Rootstock ecosystem.
As requested, the first two milestones avoid automation complexity and focus strictly on demonstrating functional user-facing flows. Only the third milestone introduces automated settlement, and its scope is clearly delineated. We believe this structure responds directly to community expectations while preserving the technical steps required for a real, production-ready Rootstock integration.
WƐCard currently serves 184 users across nine countries, offering a crypto-funded VISA prepaid card where users maintain custody until the moment of spending. Bringing Rootstock into this flow enables USDT, USDRIF, and rBTC in the future, to be used for real-world payments in Latin America and beyond — a region where card infrastructure is strong, but access to stable financial tools remains limited.
This proposal delivers a phased integration designed to maximize transparency, demonstrate real functionality early, and ensure that Rootstock becomes a viable network option for everyday commerce.
