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.

What is a tokenised carbon credit?

A tokenised carbon credit is a digital representation of a verified carbon credit that has been issued on a blockchain. It works by taking a real-world carbon credit - a certificate representing one metric tonne of CO₂ reduced or removed from the atmosphere - and creating a corresponding digital tok

What retiring a carbon credit means and why it matters

Retiring a carbon credit means permanently removing it from circulation so that it can never be sold or traded again, and its underlying emissions reduction is claimed by a single buyer. Once retired, the credit is dead in the market. It cannot be transferred, resold, or used to offset anything else

Why a carbon token's price says little about the emissions it represents

The short answer: a carbon token’s price reflects market demand, project costs, and speculation - not the actual tons of CO₂ it represents. The environmental impact of a carbon credit is determined by the quality of the underlying project and the integrity of its verification, not by how much someon

Why Registries Restricted Tokenising Retired Credits

Carbon credit registries like Verra and Gold Standard now explicitly prohibit tokenising a carbon credit after it has been retired. This restriction exists because allowing retired credits to be tokenised would break the fundamental guarantee that each credit represents a single tonne of CO₂ removed

How to trace a tokenised credit back to its project

The short answer: you trace a tokenised credit by following the token's serial number back to its registry entry, then checking that registry entry against the project documents and the credit's retirement status. The long answer involves knowing where to look, what to compare, and which gaps can ma

Carbon credit tokens and how they actually work

A carbon credit is a tradable certificate that represents one tonne of carbon dioxide (or its equivalent) that has been removed from the atmosphere or prevented from being emitted. Tokenising a credit means issuing a digital representation of that certificate on a blockchain. The idea is simple, but

How to convert crypto: on-chain vs off-chain

Off-chain (on an exchange)

Your trade happens inside the exchange's own ledger. Nothing touches the blockchain until you withdraw.

  • Cheapest and fastest for common pairs
  • Needs an account and usually ID verification
  • The exchange holds the coins until you withdraw them
  • Best for converting to and from cash

On-chain (a DEX or swap)

You swap from your own wallet. The transaction settles on the chain and you pay its fee.

  • No account, no custodian — you keep the keys
  • You pay network fees, which vary a lot by chain
  • Small or new tokens often only trade here
  • Slippage and thin liquidity are real costs on low-volume pairs
Before any on-chain swap: check the token's contract address against a block explorer, start with a small test amount, and review what you are approving — an unlimited token approval to an unknown contract is how most wallet drains actually happen.
