Fyora

Fyora is a creator money page for chain-abstracted payments. A creator shares one link, supporters pay from a Universal Balance, and Particle Universal Accounts routes value to the creator's chosen settlement chain.

Live app: fyora.app
Example creator: fyora.app/nikhil
Demo video: YouTube walkthrough
Pitch deck: Google Slides
Cross-chain proof: UniversalX transaction 0x0656d36c12e739

Problem

Creator payments are still too chain-aware. A supporter may have USDC on Base, a creator may want to receive on Arbitrum, and both sides are usually forced to think about bridges, gas, RPC networks, wallet setup, and token locations before a simple payment can happen.

That friction is especially bad for consumer creators. A creator money page should feel like sharing a normal profile link, not like explaining cross-chain infrastructure to every supporter.

Solution

Fyora turns creator payments into a single-link experience:

creators share one Fyora page
supporters pay from their Universal Balance
Particle Universal Accounts handles chain abstraction and routing
Magic embedded wallets provide email-based onboarding and EIP-7702 signing
creators receive on their configured settlement chain/token
Supabase records confirmed payments for public stats and dashboard metrics

Hackathon Tracks

Fyora is built for the Particle Network Universal Accounts Track.

Uses Particle Universal Accounts SDK in EIP-7702 mode.
Uses a Magic embedded wallet as the user-owned EOA and EIP-7702 signer.
Shows one Universal Balance across supported assets.
Uses getPrimaryAssets(), createTransferTransaction(), and sendTransaction().
Produces a real UniversalX proof link after payment execution.

Fyora also applies to the Magic Labs Bonus Challenge because onboarding and signing are powered by Magic embedded wallets. Users do not install MetaMask or manage seed phrases for the core Fyora flow.

What Fyora Does

A creator signs in with Magic email OTP.
Magic creates and owns the user's embedded EOA.
Particle Universal Accounts upgrades that EOA with EIP-7702 behavior.
The creator claims fyora.app/{handle}.
The creator chooses a settlement chain and token, such as Base USDC or Arbitrum USDC.
Supporters open the creator link and pay from their Universal Balance.
Particle routes the value and returns a UniversalX transaction id.
Fyora records the payment in Supabase and updates public profile/dashboard metrics after confirmation.

Wallet Model

Fyora keeps the wallet model simple for users:

Magic embedded wallet: handles passwordless email login and owns the EOA.
EIP-7702 signer: Magic signs EIP-7702 authorizations and the Particle transaction root hash.
Particle Universal Account: turns the EOA into a chain-abstracted account without creating a new visible wallet address.
Universal receive address: the wallet address shown on /wallet; users can deposit assets like Base USDC here.
Universal Balance: loaded from Particle getPrimaryAssets().
Payments and sends: built with Particle transfer quotes, with a createUniversalTransaction() stablecoin fallback for small cross-chain creator payouts, then executed with sendTransaction().

Real Demo Proof

The working cross-chain demo transaction is UniversalX transaction 0x0656d36c12e739.

It shows:

status: Success
asset: USDC
route: Base USDC -> Arbitrum One USDC
transaction id: 0x0656d36c12e739
from wallet: 0xea...ee3d
to wallet: 0xA6...CD9c
source chain: Base
target chain: Arbitrum One
source tx: BaseScan 0xd769f645d3fc253100176261279ba06cabc0fdfb77fcafbe280f5660aa09af07
target tx: Arbiscan 0xa4a8ff6d21aee32a1360b9dc26731a97a14b0b97a8593153cc8a43216e072391

That proof is the main demo artifact for the Universal Accounts Track because it demonstrates real value moving from Base to Arbitrum through Particle Universal Accounts.

Creator Profiles

Each creator gets:

public page at fyora.app/{handle}
payment card with preset and custom amounts
chosen settlement chain/token
avatar/photo upload
QR code for sharing
dynamic social preview image
dashboard metrics from confirmed payments only
recent supporters list

Dynamic Share Cards

Every public profile has absolute, versioned social metadata:

https://www.fyora.app/api/public/og/{handle}.png?v={updatedAt}

The generated card uses Supabase profile data, creator avatar/photo, handle, name, gradient, bundled fonts, and a real 1200x630 PNG renderer for social previews.

Data Model

Supabase stores production app data:

creator profile, handle, bio, socials, gradient, avatar/photo
Magic owner metadata and EVM address
settlement chain, token, decimals, and receiver address
payment intents and idempotency keys
Particle transaction id and UniversalX URL
confirmation status used for metrics

Public profile metrics count only confirmed payments. Pending or failed attempts do not inflate totals.

Fyora is built around one simple idea: creators should be able to share one page and receive support without asking supporters to understand chains, bridges, or gas. Particle Universal Accounts handles the chain abstraction, Magic keeps onboarding familiar, and Fyora turns that into a consumer payment experience.
