Welcome to voucherguard.pages.dev/
VoucherGuard is an open-source verification toolkit for Solana payment channels. Verify signed vouchers, spending limits, expiration, and channel state. Locally, without a backend.
Signed intent. Independent verification.
Verify what your AI agents sign.
What's the most confusing Solana transaction you've opened?
Not the biggest. The one where you couldn't tell what actually happened.
Drop a public Solscan link in the replies.
We're looking for real examples to help shape what's next for VoucherGuard.
A token account can exist for just one transaction.
On Solana, a swap may create a temporary account, wrap SOL, and close it before the transaction ends.
VoucherGuard now reconstructs supported account lifecycles from recorded evidence.
Because returned capital isn't trading profit.

An unfamiliar token isn't automatically a scam.
VoucherGuard Pro lets you build your own token mint allowlist from reviewed transactions.
When a new review shows a balance change outside your list, it flags the mismatch.
Your list. Your context. No reputation score.

You shouldn't need to connect your wallet just to understand a transaction.
VoucherGuard's free workspace is read-only.
No wallet connection. No signatures. No approvals.
Just paste a Solscan link and inspect the recorded evidence.

One sell isn't a P&L.
If your opening balance or earlier buys are missing, your cost basis isn't known.
VoucherGuard Pro's Trade Journal calculates FIFO only when the recorded trade history supports it.
No invented numbers.

Not every SOL inflow is profit.
Wrapping SOL, closing token accounts and reclaiming rent can move funds without creating trading income.
VoucherGuard now tracks supported WSOL account lifecycles and separates returned capital from trade proceeds.
Free Trade Receipt. Conditional FIFO in Pro.

Your trade deserves a receipt.
VoucherGuard now shows recorded token balance changes and network fees from a single Solscan link.
Trade Receipt is free.
Pro adds a Trade Journal with conditional FIFO calculations, partial sales and CSV/JSON exports for supported trade histories.

You sent 0.1 SOL. Did your balance drop by exactly 0.1?
Not necessarily.
Network fees, account rent and other operations can affect the final balance.
VoucherGuard's Wallet Impact shows the recorded before and after, without confusing net changes with transfers.
