KaJota Coach charges for a premium insight behind an x402 paywall. Click below and a real CEP-18 micropayment settles on Casper in front of you — signed, verified, and written on-chain. No mock mode.
Net-zero self-transfer of 0.001 KaJota USD; gas paid by Casper's sponsored feePayer — you pay nothing. Click again to settle another.
Proves the security is real: we sign a valid 0.001 payment, then tamper the recipient after signing. The EIP-712 signature binds the fields, so the facilitator rejects it.
Every x402 settlement on this CEP-18 — from this page, the KaJota mobile app, or the CLI — is submitted by the same facilitator account, so it all lands here. One rail, many clients, one on-chain ledger.
