HALOWERK kettenwerk

Checks one address on Ethereum, Base, Arbitrum, Optimism, Polygon or BNB Smart Chain against the open verification registry and against the chain itself. For a proxy the answer is deliberately split in two: whether the proxy is verified says almost nothing, whether the implementation it currently points to is verified is the real question, and both are reported separately with the implementation a

Reads the transaction history of one wallet from a public block explorer index and groups it by kind of action. Classification follows the called contract and method, never the amount - a transfer to a known router is a swap, not a payment. Anything that cannot be backed by a method name stays in the category "unbekannt", which is a valid answer here: a large honest remainder beats an invented ass

Runs each step separately as a simulation (eth_call with state override) against the current chain state and reports each result on its own, so a token that can be received but not moved on is visible as exactly that. Nothing is ever executed: no transaction is broadcast, no key is held, no approval is given. Limits, and they are decisive: can_buy and can_sell through a DEX router are NOT simulate

Provides ten explicitly allowlisted read-only RPC methods against the public Solana mainnet-beta node. AccountInfo returns metadata with zero account-data bytes. No signing, minting, airdrops, transactions or caller-selected upstream URL. Upstream throttling is an unpaid error.

Provides twelve allowlisted EVM read methods. Validates addresses, block tags, topics and byte bounds; logs cover at most 128 explicit blocks and one contract. eth_call is capped at 500000 gas. No wallet, signatures, transaction sends or node URLs supplied by the caller.
