Read-only crypto safety: token honeypot checks, EIP-712 signature decode, approval scans.
Scored across 8 tools
Each tool pair (paid and free) clearly delineates a distinct capability: approvals scanning, EIP-712 signature decoding, transaction simulation, and token safety. The free versions are explicitly described as teasers with pointers to the full paid versions, eliminating ambiguity between them.
All tool names follow a consistent snake_case pattern: base name for the paid tool and base name + '_free' for the free counterpart. There is no mixing of conventions or vague verbs.
With 8 tools, the server is well-scoped for its purpose. Although four of the tools are free variants, they serve a distinct tiered-access purpose and do not feel excessive.
The tool set covers the major wallet-safety domains: approval risks, off-chain signature risks, transaction simulation, and token rug-pull detection. Minor gaps exist (e.g., no direct address reputation lookup or transaction history analysis), but the core workflows are well covered.
PAID $0.01 (x402, USDC on Base). Scan a wallet's ERC-20/721 approvals ranked by exposure; flags unlimited amounts, unverified/known-malicious spenders, and address-poisoning 'fake-approval revoke bait'; returns the exact revoke calldata you execute YOURSELF (never executed/broadcast by us). Without payment returns the x402 challenge; pass x_payment. Free teaser: approvals_free.
Inputs: chain (required), address (required), x_payment.
FREE. Approval counts + top-3 riskiest spenders for {address, chain}. Real result, no wallet. Upgrade to approvals for EVERY approval ranked + revoke calldata.
Inputs: chain (required), address (required).
PAID $0.01 (x402, USDC on Base). Decode an off-chain EIP-712 typed-data signature (Permit / Permit2 / Seaport / generic) into plain English with risk flags: unlimited approval, unknown/known-malicious spender, never-expiring or already-expired deadlines, zero-consideration NFT-drain orders. Off-chain signatures are the top wallet-drainer vector. Pure offline decode — never signs/broadcasts. Without payment returns the x402 challenge; pass x_payment. Free teaser: decode_signature_free.
Inputs: typed_data (required), chain, x_payment.
FREE. Type + plain-English summary + risk level for an EIP-712 typed_data. Real result, no wallet. Upgrade to decode_signature for the full field-by-field decode + all risk flags + malicious-spender screening.
Inputs: typed_data (required), chain.
PAID $0.02 (x402, USDC on Base). Keyless pre-sign analysis of {chain, from?, to, data, value?}: public-RPC eth_call revert check + static calldata decode predicting approval/transfer deltas + risk flags (unlimited approval, approval-for-all, reverts). Honest keyless limitation stated in the response (no full fork trace). Without payment returns the x402 challenge; pass x_payment. Free teaser: simulate_free.
Inputs: to (required), chain (required), data, from, +2 more.
FREE. Method + revert flag + risk level + predicted effect types for a transaction. Real result, no wallet. Upgrade to simulate for the full predicted deltas + all risk flags.
Inputs: to (required), chain (required), data, from, +1 more.
PAID $0.02 (x402, USDC on Base). Multi-chain token honeypot/rug check aggregating GoPlus token-security + honeypot.is buy/sell-tax simulation into a normalized 0-100 risk score with explainable reasons: honeypot/can't-sell, buy/sell tax, mint/blacklist/pausable/ownership privileges, top-holder concentration, LP-lock, contract verified/bytecode. Descriptive facts only — NOT a buy/sell signal. Without payment returns the x402 challenge; pass x_payment to settle. Free teaser: token_safety_free.
Inputs: chain (required), address (required), x_payment.
FREE. Score band + top-line honeypot/tax/privilege flags for a token {address, chain}. Real result, no wallet. Upgrade to token_safety for the full numeric breakdown.
Inputs: chain (required), address (required).
