Ec³ Credit **Ec³ Credit** is a fuel token pegged to the US dollar, used to pay for all transaction fees within the Ec³ network. This includes purchases of Ec cubes, distributed energy, data transactions, and more. Ec³ Credit can be obtained by burning ECT. The price of a single Ec³ Credit is fixed at **0.00001 USD**. That is to say, at any time, 1 USD can be exchanged for 100,000 Ec³ Credits. Ec³ Credit can only be generated by burning HNT. The amount of Ec³ Credit produced by burning a unit of ECT will fluctuate based on the price of ECT. For example, if the price of ECT is 0.5 USD, burning one ECT will yield 50,000 Ec³ Credits. The design of ECT and Ec³ Credit is based on the Burn-And-Mint Equilibrium (BME) model, which aims to adjust the supply of ECT according to the usage volume of the network. This way, when burning and minting reach a balance, the circulation of ECT can remain stable.
