Status: waiting for your deposit
You send from your own wallet straight to the exchanger — nothing to connect, no account, and you stay on this page throughout. Rates are indicative until a swap is opened.
The swap is carried out by an independent exchanger and the deposit address above is theirs. WPay.sg never holds, receives or controls your funds, has no key to that address, and earns a referral commission. Opening a swap sends your receiving address, IP, browser and timezone to the exchanger for their compliance checks; we store none of it. Check their terms, fees and country restrictions before sending anything.

You can check for double counti

Metadata is the set of fields embedded in the token that describe the carbon credit it represents - serial number, vintage year

The vintage year of a carbon credit - the year the underlying emission reduction or removal actually occurred - tells you more about the credit's integrity than its market price ever will.
