Credit market

Each credit is one tonne of CO₂e reduced, computed on-chain from the plant's registered design and its verified monitoring data. Sellers price credits in USD per tonne. A purchase sends the HBAR amount, from Chainlink HBAR/USD with Supra as fallback, to the SaucerSwap router. The seller is paid by that swap. If the settlement pair is more than 3% from the oracle, the contract reverts and this page does not build the transaction. Without a wallet, Preview the purchase still shows that unsigned transaction. Signing needs MetaMask, HashPack, or Keplr. HashPack must be an ECDSA account. An ED25519 account cannot sign. Retiring burns the credits and mints an HTS NFT to the buyer.

Guardian-checked tokens

These are not the hydropower credit listing. Each one is an HTS token sold through UsdCheckout. Press Preview with no wallet. A token that cites Guardian is refused unless that record checks out.
