We believe, it is time moving forward to the next stage from the previously posted discussion phase.
We want to let users buy or cash out any new project token and DOT straight from wallets & dApps – no central-exchange detour, no costly listing fees for early-stage projects.
A milestone-based treasury request (~50,000 DOT) would fund:
Target: ≥10 dApp integrations and ≥60 % ramp success rate within 6 months of launch.
Today a builder must first list a fresh token on a CEX (and pay the setup fee) before any fiat ramp will even look at it. End-users meanwhile juggle KYC loops, bridges, and slippage just to touch Polkadot assets. This “double paywall” slows down adoption and burns runway.
Keep the flow fully non-custodial – users signing their transactions (aggregated); funds never sit with Vortex.
Today, Vortex is already live and serving various EVM Chains (Base, Arbitrum Ethereum etc.) as well as supporting offramps from USDC (AssetHub) in Brazil and Europe, all being routed through the Vortex DEX on Pendulum.
We propose adding the onramp feature to AssetHub Assets, upgrading to the most effective fiat routes using EURC, EURe and BRLA (via XCM, Snowbridge, Hyperbridge or Squidrouter) and adding support for DOT, USDT, Hollar and other DEX-listed Polkadot-Assets, building up a USP to the Polkadot Ecosystem.
All new functionalities shall be available through the Vortex Widget and API, all code written will be open source. Each milestone budget includes an allocation for audits.
| Milestone | Deliverable | When | DOT |
|---|---|---|---|
| M1 | PIX + BRLa integration (Avenia PSP) via API for AssetHub | Oct 2025 | 8 k |
| M2 | EURe bridging (with Monerium EMI) + Instant SEPA onramping | Nov 2025 | 20 k |
| M3 | Integration with new Polkadot Hub including price-oracle pushed onchain (pending separate gas sponsoring proposal) | Jan 2026 | 7 k |
| M4 | Oracle-based DEX rollout for bootstrapping initial EURe and BRLA liquidity | Feb 2026 | 5 k |
| M5 | Add DEX routing through Hydration | Feb 2026 | 10k |
Total: 50 000 DOT
Partners: Monerium (EU EMI licence, EURe issuer), Avenia (Brazil BRLA issuer), Ramp aggregators (e.g. meld.io) .
Compliance: full KYC/AML handled by partners; Vortex provides the self-custodial UX and chain abstraction
Vortex aggregates and bundles the fiat ramp flow together with DEX swaps into a single user transaction. By connecting directly to stablecoin issuers’ infrastructure, Vortex eliminates unnecessary intermediaries, cuts costs, and mitigates risk — all while utilizing DeFi infrastructure including DEXs, bridges, and abstraction of cross-chain complexity.
1. Minting/redeeming EURe for fiat EUR on Polygon/Gnosis → Bridge Monerium-issued EURe into/from Polkadot (Hyperbridge)
2. Swapping to target token
3. Vortex → Handles fiat settlement starting with Instant-SEPA (Europe) & PIX (Brazil) and swapping/bridging via API + widget
4. Builders → Integrate the Vortex widget/API → users can directly ramp fiat into tokens on their dApp, once it has DEX liquidity. Focus maintained by avoiding premature CEX listings.
