Changelog
What changed, and when.
Newest first. Corrections to figures or methods are listed with the date they went live.
A page for every asset, network and exchange
Fees by asset: a hub per asset (USDT, USDC, BTC, ETH, SOL, TRX, LTC) ranking every network by total cost right now, and a page per asset-and-network pair with the live on-chain fee, every exchange’s withdrawal fee and minimum, the 24-hour sparkline, how-to-send steps and computed answers to the usual questions. A page per exchange (Binance, KuCoin, HTX, and honest not-readable pages for Bybit and OKX) with every rail, the cheapest per asset and where to check the fee yourself. Network names on the front page and in the exchange matrix now link through; nothing new is fetched, every page reads the same cached snapshots.
Exchange fees, a route planner, an address check and 24h history
A withdrawal-fee matrix reads what Binance, KuCoin and HTX charge to let USDT, USDC, BTC, ETH, SOL, TRX and LTC out on each network and puts it next to the network fee (Bybit and OKX are listed as unavailable because their endpoints are blocked or need a login from our server). A route planner adds the exchange fee to an optional on-chain hop and ranks rails by total cost for your amount. An address checker tells you which network an address belongs to, entirely in the browser. The front page now logs the USDT fee at most every five minutes and shows a 24-hour sparkline with low, median and high per rail. New JSON at /api/exchanges and /api/fees/history.
The desk gets its own front page
CheapestChain moves off the shared template onto a printed-page design of its own, adds per-page share images, schema.org Dataset markup for the fee snapshot, a nonce-based Content Security Policy, rate limiting on the public API, and about, methodology and contact pages.
Price fallbacks
USD prices now come from Coinbase first, then Kraken, CoinGecko and Binance for anything missing, so TRX and other assets Coinbase does not quote stay priced.
CheapestChain launches
Live transfer fees for USDT on Tron, Solana, BNB Smart Chain, Polygon, Arbitrum and Ethereum, plus native Bitcoin, Litecoin and Ether sends, read from the networks at request time. Free JSON at /api/fees. Country guides for Nigeria, South Africa and New Zealand.
