The basic economic model of the Carbon token

Block Rewards


Block rewards come from SWTH emissions and protocol fees.

  • SWTH Emissions refer to SWTH tokens generated by the network with each block through an inflation curve.

  • Protocol Fees refer to the fees that traders and other network participants pay for using the network.


The block rewards on Carbon are split and distributed in this ratio:

SWTH Emissions

SWTH follows an inflationary token model that decreases in inflation rate over time, and is issued as part of block rewards over 5 years. After the 5th year (31 March 2025), no new tokens will be issued.

Emission Rate

For the first 5 years after the launch of the protocol (21 August 2020), emission of SWTH as block rewards will occur on a weekly basis. In Week 1, the emission of SWTH began at a rate of 1.65%, decaying by 1.65% week-on-week. After Year 5, no new tokens will be issued.

What This Means for SWTH Holders

Currently, about 90% of all SWTH is in circulation, which reduces the inflationary pressure for SWTH holders. With most of the downward selling pressure gone, more and more of the staking rewards will be from fees generated by activities on the Carbon blockchain, i.e. real yield from protocol fees.

We explain in greater detail in the Carbon protocol fees section.
