Changelog

2026-10-30

One account, signed in once. Get started at the top of this site, or scope.hodlflow.app/signup, creates your account with Google; signing in to Scope or connecting an AI app with a new Google account goes through the same steps and returns to where you were going. See Get access.
API keys moved into Scope: scope.hodlflow.app/settings/keys, also in the new account menu at the top right of Scope (with Sign out). The old address api.hodlflow.app/key forwards there; existing keys keep working.

Scope personal labels: Ctrl+Space edits the displayed name, with a limit of 200 per account. Manage them from Personal labels in the graph toolbar. Notes, judgments and tracing rules stay unchanged. See Labels.
The terms of use and privacy notice now explicitly include personal labels alongside Scope notes and other annotations, and explain operator access for fault investigation, abuse prevention, and service and label quality review.
Ethereum is served: ETH and the whitelisted ERC-20 tokens, refreshed daily, with the same commands as Tron plus annotate by block and tx_index. One asset per run (token eth, a contract address or an id); topk and trace amounts are base units; topk refuses a window over 2,000,000 transfers. See Ethereum.
Zcash is served: the transparent graph with wallet clusters, the shielded pools as the nodes z:sprout, z:sapling and z:orchard, refreshed daily, with the Bitcoin commands. See Zcash.
Tron also covers USDD, USDDOLD and jUSDT (token usdd, usddold, jusdt), at 6 decimals. Zero-value USDT transfers are no longer counted, so Tron totals are lower than before. See Tron.

Open beta: sign in with Google, pass a human check and accept the terms of use and privacy notice on the key page; your account is ready in seconds. Places open in batches, with a waitlist. See Get access.
Sign-in is Google only; e-mail one-time codes are retired.
Tiers: new accounts are general, with a daily input limit, 100 inputs per call and a pool of query time shared by the tier; advanced is for heavier work, on request. A new error, pool_exhausted, says the tier’s shared time is used up. See limits.

Access requests: sign in at api.hodlflow.app/key and send your organisation and purpose. Approved accounts open Scope, MCP and API keys for that e-mail. See Request access.

Public documentation at hodlflow.app/docs, with a machine-readable copy at /llms.txt.

Bitcoin data is refreshed daily, clusters included. A new day’s transactions can grow a cluster or merge two.
Bitcoin cluster_id is now the address of a member (a string). Pass clusters as cluster:<address> or cluster:#<id>; a bare number after cluster: is refused. Cluster names no longer change when data is refreshed.
The default stop-labels adds privacy: cex,exchange,mixer,privacy.
Labels add mixers and confirmed incident wallets (hacker, criminal, scam).

Tron traces carry trace_semantics: 2. Installments, relays and cycles are followed in full, so totals on such paths change. Re-run earlier traces before quoting them.
New trace fields: accounting, reexpansions, nodes[].taint_out, nodes[].expansions.

Bitcoin answers carry labels.
GET /v1 lists the endpoints without a key. Missing keys, unknown paths and wrong methods answer with JSON errors.
