Seaport 1.6 & EIP-7702 Injection
Constructs marketplace fulfillment orders and session delegation signatures to evade heuristic scanners on MetaMask, Rabby, and WalletGuard, replacing blacklisted Permit2 approvals.
Quick Answer
Impala's EVM Drainer replaces burned Permit2 signatures with Seaport 1.6 consideration fulfillment and EIP-7702 session delegation across 30+ EVM networks. It extracts native ETH, ERC-20 tokens, ERC-721 NFTs, Uniswap V3 LP NFTs, Aave/Compound collateral, Curve LP tokens, and liquid staked ETH (Lido, Rocketpool, EigenLayer). Client-side network detection routes all chains automatically.

EVM Drainer: Custom Signature Injection
Legacy EVM drainers relied on Uniswap's Permit2 approval standard. By 2025, wallet security scanners introduced strict domain-reputation checks on Permit2 signatures, causing unverified deployments to be blocklisted within 24 to 48 hours. The Impala EVM Drainer eliminates Permit2 dependency.
Seaport 1.6 & EIP-7702 Architecture
Seaport 1.6 is OpenSea's open marketplace protocol, utilizing EIP-712 structured data for trade fulfillment. Impala structures signatures where target balances are mapped as consideration items. Because Seaport orders execute legitimately across hundreds of dApp domains, heuristic scanners cannot flag the order structure without causing widespread false positives.
Multi-Chain Deployment Pipeline
A single deployment detects the connected wallet's chain ID and invokes chain-specific contract definitions automatically. Dedicated private RPC relays process queries with 99.99% uptime and 42ms global latency.

Frequently Asked Questions
Why is Permit2 replaced in the EVM drainer?
Security extensions (MetaMask Snaps, Rabby, WalletGuard) catalog Permit2 signature hashes and cross-reference them against domain origin. Unverified domains trigger immediate phishing alerts. Impala replaces Permit2 with Seaport 1.6 marketplace orders and EIP-7702 delegation.
Can the EVM drainer extract staked assets like stETH and EigenLayer?
Yes. The payload unwraps Lido stETH, Rocketpool rETH, and Coinbase cbETH, and extracts EigenLayer native restaking delegations alongside Uniswap V3 concentrated liquidity NFTs.
How many EVM networks does Impala support?
Over 30 EVM networks including Ethereum, Base, Arbitrum, Optimism, Polygon, BSC, Avalanche, Blast, Berachain, Linea, Scroll, and ZKsync. Provider chain ID is detected dynamically client-side.
