The current list is always visible on the site and in the app's token picker — it is read from the live registry rather than written into the page. At the time of writing that is USDG, WETH, native ETH, and RECYV. ## Verification Every address in the registry is checked against the chain before it goes live: that code exists at the address, and that the symbol and decimals match what the registry claims. The decimals check is the one that earns its keep. USDG uses six decimals and WETH uses eighteen; getting that wrong misprices every payment by a factor of a trillion, silently and with no error. ## Native ETH ETH is the gas token and has no contract, so it is handled differently: paying sends transaction value rather than calling `transfer`. Two consequences. Gas comes out of the same balance, so a payer cannot send their entire holding. And because there is no transfer event, an ETH payment is tracked by its receipt rather than by scanning logs. ## Adding a token Adding one is a registry change, not a release. It appears in the picker, the supported-token list, and the payment page within about five seconds of being added. --- # Agent Instructions This documentation is published with GitBook. GitBook is the documentation platform designed so that both humans and AI agents can read, navigate, and reason over technical content effectively.

Perform an HTTP GET request on the current page URL with the `ask` query parameter, and the optional `goal` query parameter: ``` GET https://docs.recyv.xyz/how-it-works/tokens.md?ask=&goal= ``` `ask` is the immediate question: it should be specific, self-contained, and written in natural language. `goal` is optional and describes the broader end goal you are ultimately trying to accomplish on behalf of the user. GitBook uses it to tailor the answer towards what is most useful for that goal. The response will contain a direct answer to the question and relevant excerpts and sources from the documentation. Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
