Cross-Platform Hybrid Architecture Mobile Wallet for Conflux Ecosystem（revised proposal）
Dear @francz ,
Thank you for the detailed proposal — the hybrid wallet + BSIM integration concept is well aligned with Conflux’s mobile ecosystem direction.
However, before this application can proceed, several core grant requirements are still missing:
⸻
- Milestone 1 should be pre-grant
Your current Phase 1 (UI/UX design, wireframes, prototyping – 15% budget) is considered pre-grant work in our framework.
Grant milestones should start from working technical implementation and Conflux integration (e.g., custodial wallet on testnet, CFX transfers, RPC integration, etc.).
Please move design/prototyping outside the funded scope and restructure milestones accordingly.
⸻
- Missing numeric & verifiable KPIs
All milestones currently describe activities, but not measurable outcomes.
Each milestone must include numeric, verifiable KPIs, such as:
• number of Conflux wallets created
• on-chain transactions
• DAU / MAU
• BSIM signings
• dApps integrated
• social/community growth
• performance / uptime metrics
and a clear payment trigger (explorer links, dashboards, third-party verification, etc.).
⸻
- Grant size adjustment
The current request of $80,000 exceeds our Integration / Growth grant cap.
Please revise the total grant request to maximum $50,000, with exact USD amounts per milestone (not only percentages) and a clear budget breakdown (dev / infra / security / marketing).
⸻
- Other missing items
• Legal entity / grant recipient details (you marked “not incorporated”)
• GitHub or technical repository
• Custody & compliance model for custodial accounts
• Quantified ecosystem impact (expected users / transactions on Conflux)
• Team links (LinkedIn / GitHub) and full-time vs part-time roles
⸻
Next step
Please submit a revised proposal covering the above points. Once updated, we can reassess eligibility for committee review.
Best regards,
Máté
