Polkadot is set to overhaul its economic framework on March 12, 2026, introducing a cap on DOT supply at 2.1 billion. The changes include a new DOT issuance model, Dynamic Allocation Pools (DAP), and updates to staking and network security. The DAP will replace the current treasury burn mechanism, channeling transaction fees and other revenues into a permanent account for dynamic budget allocation. The new issuance model will release 13.14% of the remaining supply every two years, with an initial issuance volume reduced by 53.6%. Staking mechanisms will also see significant updates. From mid-to-late March, validators will need to maintain a minimum of 10,000 DOT in slashable self-stake and set a minimum commission rate of 10%. In April, nominators will become non-slashable, and the unbonding period will be reduced from 28 days to between 24 and 48 hours.
