SVM402
Solana x402 conformance and resilience lab
SVM402 is a payment conformance and resilience lab for Solana x402: seventeen deterministic payment-failure scenarios run on the real verify and settle machinery, and each settle lands an on-chain receipt. Every conformance call is paid per call in USDC via x402 v2 — no accounts, no prepayment. Scenarios run on devnet first, then mainnet, and the lab path is the production gateway path: the rehearsal is the real money behavior.
