Attested pre-transaction counterparty check for any Base/EVM wallet: exact match against OFAC SDN digital-currency addresses, on-chain profile, and a transparent clear/caution/flagged verdict with reasons — ML-DSA-65 signed and Hedera-anchored.

Wallet PnL analysis

Total Transfer Volume (Change-Adjusted) — The total amount of coins transferred on-chain, adjusted by change volume. Data by Glassnode.

Number of Addresses with Balance ≥ 0.01 — The number of unique addresses holding at least 0.01 coins. Data by Glassnode.

Number of Addresses with Balance ≥ 1k — The number of unique addresses holding at least 1k coins. Data by Glassnode.

Where did this address get its money? Walks the funding chain upward and returns the account that ultimately paid for the wallet, plus a cluster id. Two addresses funded from the same account are not independent parties, however new and unremarkable each looks alone — the strongest cheap signal there is that an identity was manufactured. Works on any address, not only registered agents.

High-velocity DEX liquidity changes detecting significant market moves.

EVM wallet activity feed - newest-first transfers, swaps, approvals, NFT movements, and decoded contract calls

Normalized insider transactions (Form 4) with flow aggregates for a ticker — SEC Form 4 filings parsed into clean insider transactions: buy/sell/award classification, 10b5-1 plan flags, per-filer roles, and aggregate net flow with notable-pattern flags. Use it to gauge insider conviction before events.

Single-trade T+1 settlement date, as a one-line GET: given a trade date and an as-of date, returns the settlement date and whether it has settled, on the versioned NYSE holiday calendar with SEC Rule 15c6-1 cited. The low-integration sibling of the batch settlement-dates route — no request body. A dates fact, never a violation determination. Nothing is stored.

Batch wallet snapshots for multiple Base addresses in one paid call, all anchored to a single block: native and ERC-20 balances, account flags, and derived metrics per address. Efficient multi-wallet portfolio and balances lookup for AI agents.

Tx Intent Classifier: decodes the REAL intent of an on-chain transaction (Base/Ethereum) and returns an Ed25519-signed risk verdict (safe/review/suspicious/dangerous). Catches unlimited approvals, opaque selectors, value-to-contract, reverted tx. POST {"tx_hash":"0x..","chain":"base"} or {"to":"0x..","data":"0x.."}.

Wallet intelligence: EOA-vs-contract, ETH+USDC balance, tx count, activity/risk flags.

Verify an exact Circle USDC payment from a Base-mainnet transaction receipt and finalized chain evidence

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 simulated - that needs a funded account and a router path this service cannot back, so both stay null. What

Seed402 wallet diligence report v0: USDC revenue analysis on Base — inflow totals, unique payers, concentration, activity span, and a transparent 0-35 revenue-verification subscore. POST JSON {"address": "0x..."}.

Buyer-side MOVE/HOLD decision for WETH lending on Base — same contract as the USDC decision route, for WETH. Verified per-asset accuracy is free at /accuracy.json; raw on-chain attestations at /track-record.

Deployer address and creation transaction for a contract address, from Etherscan's V2 API -- who deployed it and when, pairs naturally with /contract-source. A non-contract or unrecorded address returns found=false rather than an error. $0.01/call.

Actionable GBLIN treasury recommendation (invest/hold/reduce/defer) with confidence score and suggested allocation percentage, driven by live on-chain Crash Shield state on Base. Combines Chainlink price risk, treasury analytics and drawdown regime into one decision an agent can act on.

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 assignment. Limits: history comes from a public index available for Ethereum, Base, Arbitrum and Optimi

Reads Approval events of one wallet from the chain, resolves the CURRENT allowance for every token and spender pair with a direct call, and weighs it against the balance actually held. An unlimited approval on an empty balance carries no risk and is reported as such. Every entry carries ready-made call data to revoke it - this service never signs and never sends anything, the caller decides. Limits: Approval events are read from a bounded block window, not from the whole chain history; the windo

Signed wallet trust fact profile: presence checks across stablecoins, governance, NFTs, staking and institutional dimensions, up to 49 checks on 27 chains. Evidence organized by dimension, no score, no opinion. Vet a counterparty wallet before an agent transacts.

Bitcoin chain-tip orphan + valid-fork stream (10min cadence). For exchange confirmation-policy tuning, cross-chain bridge safety windows, finality auditors. branch_length >= 2 = unusual reorg risk.

Collects the addresses a wallet interacted with from its transactions and token transfers, counts the interactions per edge and names the type of each contract where it can be backed by a curated entry or a verified contract name. Depth is capped at two by design: anything deeper turns this into a tool for de-anonymisation, and that is not built here. Limits and the rule that matters: only contract designations and service types are reported. There is NO assignment to natural persons, no names,
