# Drainvault

*/Startups/Drainvault*

## Startup Overview

This transaction security layer intercepts and simulates smart contract calls immediately before cryptographic signature. It executes the pending transaction in an isolated sandbox, exposing exactly which tokens, NFTs, or permissions will leave the user's wallet. Users view the definitive outcome of their interaction rather than guessing at unreadable hex data.

Decentralized finance traders and Web3 users routinely lose funds to wallet drainers because they are forced to blind-sign malicious contracts. Standard interfaces provide no visibility into the actual state changes triggered by an approval or transfer. By mapping the exact asset flow prior to execution, this system eliminates the risk of hidden payloads.

Legacy protections fall short: hardware wallets secure private keys but blindly sign anything, while browser extensions like Pocket Universe or Blockaid rely on probabilistic heuristics and known-threat blocklists. This infrastructure replaces guessing with deterministic execution, calculating the exact blockchain state change. It operates with zero-latency overhead, guaranteeing definitive security without delaying time-sensitive transactions.

## Startup Offer

**Proof**:
- Targeting 100% deterministic interception of exact state-draining contract calls.
- Aiming for under 50ms overhead per transaction simulation to prevent execution delays.
- Designed to protect high-volume prosumer wallets averaging high daily transaction counts without latency penalties.
**Tiers**:
- Name: Active Trader · Price: ~$20–$50/mo · Inclusions: Browser extension intended for up to 3 individual wallets, designed to provide unlimited EVM transaction simulations and deterministic threat flagging before signature.
- Name: Fund Node · Price: ~$500–$1,500/mo · Inclusions: Dedicated RPC endpoint access intended for institutional programmatic trading, covering up to 100,000 simulated transactions per month.
- Name: Wallet Integrator · Price: ~$3,000–$8,000/mo · Inclusions: Enterprise API access designed to embed deterministic simulation directly into native wallet signing flows, supporting up to 1 million signature checks per month.
**Guarantee**: If Drainvault fails to intercept a deterministic smart contract drain that matches its simulation criteria, we will refund the last 12 months of your subscription fees.
**Business Function**: ProvideService
**Objection Handlers**:
- Latency will ruin my snipe trades: The simulation is designed to execute against a localized state map, targeting near-zero latency overhead compared to standard remote RPC calls.
- Scammers constantly bypass heuristics: Drainvault evaluates exact deterministic state transitions (calculating the literal asset movement) rather than guessing based on heuristic pattern matching.
- I refuse to give another extension my keys: Drainvault is designed to solely read the unsigned transaction payload; it never requests, stores, or accesses your private keys.
- Simulations are often inaccurate: The engine is intended to mirror exact mainnet state at the pending block, ensuring simulated token flows exactly match final on-chain execution.

## Startup Proof Points

_Illustrative — target and order-of-magnitude estimate figures, not an achieved track record (this Thing is concept-stage)._

**Pilot Goals**:
- A 30-day API integration pilot with a consumer Web3 wallet aiming to process 1 million signature checks and block 100% of deterministic phishing attempts without degrading user checkout times.
- A 14-day RPC endpoint trial with an institutional fund evaluating 100,000 simulated transactions to validate sub-50ms latency against localized state maps.
**Target Metrics**:
- target: <50ms latency overhead per EVM transaction simulation
- aim: 100% deterministic interception of exact state-draining contract calls
- target: 0 private key exposures during unsigned transaction payload reads
**Target Case Studies**:
- A high-volume prosumer DeFi trader using the browser extension to simulate high-frequency swaps, catching zero-day phishing contracts without missing snipe trade execution windows.
- An institutional algorithmic trading desk routing programmatic trades through the dedicated RPC endpoint to intercept malicious state changes automatically before broadcasting.
- A consumer Web3 wallet integrating the enterprise API to embed deterministic simulation into their native signing UI, preventing user asset loss from malicious airdrop claims.
**Testimonial Targets**:
- Prosumer DeFi Trader expressing that the extension evaluates exact asset movements and stopped a hidden drainer without causing them to lose a time-sensitive mint.
- Quant Trading Lead affirming the dedicated RPC endpoint reliably maps exact mainnet state at the pending block without disrupting programmatic execution speeds.
- Head of Product at a Consumer Wallet stating the API integration directly prevents malicious signature execution and reduces customer support tickets regarding stolen assets.

## Startup Top Risks

**Risks**:
- Severity: existential · Description: Major wallet providers integrate native deterministic transaction simulation directly into their signing interfaces, bypassing the need for an external interceptor. · Mitigation Status: unmitigated
- Severity: high · Description: The deterministic simulation engine fails to accurately resolve novel proxy contracts, resulting in a false negative that drains user assets and destroys product trust. · Mitigation Status: in-progress
- Severity: high · Description: Achieving zero-latency overhead requires reliance on centralized RPC infrastructure that suffers outages or rate limits, completely blocking user transaction flows. · Mitigation Status: in-progress
- Severity: moderate · Description: Incumbent security extensions leverage their existing browser distribution channels to switch from heuristic to deterministic models, neutralizing the core differentiator. · Mitigation Status: unmitigated
