Description
BlinkGuard is a safety firewall for Solana Actions (Blinks). Paste any Action/Blink link → we resolve it, decode the returned transaction, simulate it, and show intent + touched programs + risk flags *before you sign*. Designed for CT power-users. Simulate-only by default (no signing/execution in MVP), with an explicit gate for any future execution.

Solana Actions/Blinks are increasingly used as ‘one-click’ links, but users can’t reliably see what transaction they’re about to sign. Attackers exploit this with claim/verify/token-gate and checkout-like flows. Users need a fast, CT-native way to understand intent + blast radius BEFORE signing.
Target Audience
Primary: CT power users who routinely click blinks/links (traders, airdrop hunters, community mods). Secondary: wallet teams and app devs who want an ‘intent + risk’ layer to embed in their link preview/confirm flows.
Technical Approach
BlinkGuard implements the Solana Actions flow (fetch action metadata, request the returned base64 VersionedTransaction), then: (1) decodes the VersionedTransaction, (2) resolves Address Lookup Tables, (3) extracts touched program IDs + instruction patterns, (4) runs an RPC simulation, and (5) evaluates a policy/risk rule set to produce a readable verdict + receipts. Ships as a Telegram bot + a web demo/API; simulate-only by default with an explicit future execution gate.
Solana Integration
Implements the Solana Actions flow (GET metadata + POST tx), decodes base64 VersionedTransactions, resolves Address Lookup Tables (ALTs), extracts instruction program IDs, and simulates via Solana JSON-RPC (mainnet/devnet).
Business Model
B2B: offer BlinkGuard as an API/SDK to wallets and dApps (per-request pricing or monthly plan). B2C: pro tier for power users (advanced rules, watchlists, saved receipts). Long-term: ecosystem safety router that reduces support/chargebacks and increases conversion by adding trust.
Competitive Landscape
Wallet simulators + scanners exist (wallet preview UX, generic transaction simulators), but they’re not optimized for the Solana Actions distribution channel and often don’t highlight ‘intent’ and program-level risk clearly. BlinkGuard’s edge: Actions-native link resolution + tx decode + ALT resolution + simulation + simple, shareable receipts focused on touched programs and worst-case outcomes.
Future Vision
Become the default ‘intent firewall’ for Solana one-click actions: richer instruction-intent classification (approve/delegate/session), domain/origin verification, allowlists and reputation, and optional safe execution flows (user-approved) with policy constraints. Expand to more wallets/chains only after Solana-first is solid.
