S1lkPay Checkout

Stablecoin checkout and virtual-card funding demo with customer authorization, compliance screening, issuer treasury settlement, and audit evidence.

API: Degraded

Phantom signs an authorization message for the relayer, not a wallet-spending Solana transaction.

The backend verifies the signature, screens compliance, and records audit evidence.

Approved settlement is submitted by the configured issuer or relayer treasury key.

Authorization

The signer authorizes this checkout payload for compliance review. No seed phrase is requested, and Phantom is not asked to submit a token transfer.

Disconnected

Demo Signer Fallback

Generated browser identity

This fallback uses an ephemeral WASM keypair for local demos only. It is not a real customer wallet.

Checkout Session

No checkout session

Create a session to produce a payable authorization payload.

Transfer And Audit

No signed transfer

After authorization, the linked transfer and audit report appear here.

Confidential Transfer Capability

Caveated

Public SOL and SPL stablecoin checkout is the live demo path. Token-2022 confidential transfers remain a backend/network capability, but they are not exposed as an interactive public checkout control here.
