In the status code table for network requests, code 402 has been left unused for more than thirty years. What it says is “payment required.” Around September 9, a set of components from Cardano was integrated into this standard’s public library, with the mainnet and two testnets all listed.
The client asks the server for data; the server returns a 402. The client signs a transaction on-chain and sends it along with the request. After verification, it delivers the result. The whole process happens between one request and one response—no account needed, no key to obtain, no subscription to negotiate. The server recognizes only the signature in the transaction.
Cardano, Stellar, Hedera, and Algorand are all on Binance’s spot listings: their market caps are roughly $9.23B, $7.42B, $4.08B, and $1.0B respectively. Over one month, they’ve risen by 13.3%, 11.9%, 21.2%, and 24.1% in sequence. The ceilings for all four are fixed; the difference is how much of the quota they’ve released—Algorand has already released all of it; Hedera has 87.7%, Cardano 83.4%, and Stellar 69.9%. The more left, the smaller the monthly swing.
This channel, besides its native tokens, also accepts stablecoins that are priced on-chain in USD—there’s more than one. The transactions handled as “pay-as-you-go” are mostly run by programs, so it’s not appropriate for it to absorb a round of price volatility. The point is exactly here: on the fee side, on-chain native tokens must still be used for settlement. As a result, the cost of a single call is split into two parts—what you receive lands in stablecoins, and what passes through lands in the home token.
I checked its circulating supply and cap: 37.53B tokens versus a 45B token cap, with 16.6% never having entered circulation. As of September 22, the price was $0.246, this round’s increase was 5.57%, market cap about $9.23B, 24-hour trading volume $0.922B, and turnover roughly 10%. Current chain throughput is about 4.5 KB per second; a single demo pushed a node to 250 KB.
What was changed was the storage location of this set of components; the chain itself didn’t gain any new capability. This standard was proposed earlier by a payment provider, and it’s now governed by an industry consortium. Where I’m wrong is straightforward: if the number of payment transactions grows week over week, while the total on-chain fees line stays flat, then this view doesn’t hold. The ADA needed for these payments is listed in 12 trading pairs on Binance spot; the price can be seen on the quote page and it can also be bought directly.
