Demo dApp: Gasless Classic Payment (XLM Send)

[0xVida]

Description:
Build the simplest possible demo: a gasless XLM payment for Classic Stellar transactions.

Requirements and Context:
Not all Fluid users are building Soroban dApps. A classic payment demo shows Fluid works equally well for basic remittance use cases.

Acceptance Criteria:

• Minimal React form: enter destination address and amount
• Fluid sponsors the transaction fee
• Shows the confirmed tx link in Stellar Expert
• Works with any Stellar wallet (Freighter)

Deliverables:

• Implementation of the above criteria
• Tests or proof of correct behaviour

NOTE: This issue will NOT be reviewed or approved without evidence (screenshot, log, or test output) demonstrating the feature works as described.

Suggested Execution:

1. Build a minimal React app with freighter-api integration
2. Use the Fluid SDK to sponsor the Payment operation
3. Deploy to GitHub Pages as a reference implementation

Guidelines:

• Follow the existing project coding conventions
• All new environment variables must be documented in .env.example
• Phase: Phase 15: Community
