Coston2 testnet only. No real funds. MockUSDT0 has no market value.
What you unlock
Flare x ProofRails: Verifiable Financial Messaging for Onchain Payments
A thesis on x402, Flare, ISO 20022-style receipts, and accountable crypto payment infrastructure. Includes competitive analysis, real market data, seven builder opportunity analyses, and verified Coston2 test evidence.
How it works
Connect and fund
Connect an EVM wallet, switch to Flare Coston2, get C2FLR gas from the faucet, and claim MockUSDT0 test credits.
Pay with x402
The app presents an HTTP 402-style payment requirement. Your wallet settles 0.001 MockUSDT0 through the Coston2 x402 facilitator contract.
Unlock and verify
Settlement is verified on-chain. The research brief unlocks. ProofRails creates an evidence record linking the payment to the resource.
The thesis
"x402 unlocks paid access. Flare settles and verifies programmable payment context. ProofRails turns the payment into verifiable financial evidence."
A transaction hash proves that value moved. It does not prove what the payment meant. No existing crypto payment platform produces ISO 20022-style structured receipts, supports x402 natively, and provides a verifiable audit trail. ProofRails is built for this scope.
