Blnk Watch changelog

Time-based rules

Rules that use time functions now evaluate correctly. You can write conditions such as hour_of_day(created_at) >= 22 or day_of_week(created_at) in ("Saturday", "Sunday") and Watch applies them using the transaction’s created_at timestamp. Time functions also support in and not_in for lists of hours, weekdays, or day names.

Previous transaction rules

The previous_transaction() function now works as documented. Watch looks back from the current transaction’s created_at and checks whether a matching transaction exists in that window. You can match on table fields such as source and status, or metadata paths such as meta_data.status.

Private HTTPS rule repositories

Watch can clone and pull private rule repos over HTTPS with WATCH_SCRIPT_GIT_USERNAME and WATCH_SCRIPT_GIT_TOKEN. Username defaults to x-access-token when unset. Credentials stay out of logs and Git status responses.

Rule name on verdicts

Each entry in dsl_verdicts now includes the rule name alongside rule_id, verdict, score, and reason. Alert webhook payloads carry the same shape.

Install Blnk Watch with one command

v0.1.2 is the first release with prebuilt binaries. Install on Linux or macOS (Apple Silicon) with:

curl -fsSL https://blnkfinance.xyz/install/watch | bash

Welcome to our first release

Blnk Watch is live. You can monitor ledger transactions with custom risk rules, get a verdict for each transaction, and enforce limits, fraud checks, and compliance controls without running heavy infrastructure.

WatchScript rules

Write rules in WatchScript (.ws), a domain-specific language for transaction monitoring. Define conditions on amount, source, destination, metadata, aggregates, and time windows, then set a verdict when a rule matches.

Transaction evaluation

Send transactions to Watch for real-time evaluation. Watch returns a consolidated risk assessment with a verdict such as allow, review, or block, plus scores and reasons from each triggered rule.

Blnk Core integration

Connect Watch to Blnk Core to evaluate transactions as they are recorded. Register a webhook so new transactions flow into Watch automatically, or sync historical transactions from your Core database.

Rule management and deployment

Store rules in a Git repository and let Watch sync them on a schedule. Compile instructions through the API, deploy the binary, and configure sync with environment variables.
