How VerifDoc accepts USDT on Tron without a payment processor

·1 views

VerifDoc added crypto top-ups after many South Asian customers asked for USDT on the Tron (TRC-20) network, which is cheap to transact on. The company uses a pool of Tron wallets, scanning TronGrid for incoming transfers and confirming each one on a solidity node before crediting an account. To avoid fake tokens, it matches the official USDT contract address rather than the token symbol, and checks the receipt and Transfer event. Wallet addresses are checksum-verified, and each transfer is recorded only once in the database, preventing double credits. The team tested the full flow against a real mainnet transfer and reported that the first customer deposit arrived the day after launch.

Public-Sector Logins Secured via Low-Cost SMS OTP API in Node.js 2FA Setup

A developer guide describes using a dedicated SMS one-time-password API for two-factor login in a Node.js public-sector appointment application, keeping the provider from storing or matching codes. The application still handles expiry, resend timers, attempt lockouts, consent, and monitoring. The article argues that SMS costs scale with message sends, so reducing unnecessary resends and abuse matters more than the per-message rate. It recommends keeping a separate append-only audit record of each access decision, without storing codes, message bodies, or bearer tokens. A Go example shows how to check the provider's live API schema while handling rate limits with backoff.

Three single-file HTML tools replace IT spreadsheets for racks, IPs and inventory

A developer built three IT documentation tools to replace the spreadsheets small teams typically use for server racks, IP addresses and equipment inventory. Each tool is a single index.html file that runs in any browser without a server, database or account. The rack tool maps devices and ports with cable details, the IP tool tracks address states, VLANs and subnets, and the inventory tool flags expiring warranties and support contracts. Data is stored in a user-controlled JSON file that can sit on a network share, and the tools are open source under AGPL-3.0 with English and Spanish support.

Staged Retrieval Design for Privacy-Focused Logistics Knowledge Search at Scale

A logistics knowledge manager can keep near-duplicate detection explainable and index costs under control by adopting a staged retrieval design with explicit collections, bounded queries, and traceable source context. The approach begins by defining the retrieval unit, mandatory metadata filters, and freshness requirements before choosing any endpoint. The article compares FAISS, pgvector, Qdrant, Pinecone, and managed REST vector APIs, noting that each trades off operational responsibility, database coupling, and data residency concerns. Evaluation relies on small, hand-inspectable test sets with failure cases, such as a delayed-delivery note that gets re-entered with a changed tracking number. Because cross-owner matches are treated as more serious than slightly lower top-k scores, the guidance favors a two-pass query that applies owner and document-type filters before scoring candidates.
