Weekly emissions controller for RAM. The current implementation in Minter.sol is the contract-enforced source of truth for supply caps, multiplier updates, and weekly emissions minting.

​
Core Functions

​
kickoff

One-time operator-only initialization. Sets the token and governance addresses, seeds the initial emissions configuration, and mints the INITIAL_SUPPLY to the operator.

​
initEpoch0

Starts epoch accounting by setting firstPeriod, activePeriod, and minting the configured week-0 emissions to the operator.

​
updatePeriod

Permissionless weekly rollover function. When a new period has started, it:
  1. Computes the next weekly emissions amount
  2. Mints that amount to the Minter contract
  3. Approves the Voter
  4. Calls Voter.notifyRewardAmount()

​
updatePeriodAndRebase

Convenience entrypoint that advances the period and then calls rebase() on xRAM.

​
updateEmissionsMultiplier

Governance-only update for the emissions multiplier. The contract enforces a maximum deviation of 25% per update.

​
calculateWeeklyEmissions

Returns the next emission amount after applying the multiplier and the supply cap.

​
Key Concepts

  • INITIAL_SUPPLY is 350,000,000e18.
  • MAX_SUPPLY is 1,000,000,000e18.
  • BASIS is 10_000, and MAX_DEVIATION is 2_500, meaning multiplier changes are capped at 25% per update.
  • updatePeriod() returns the active weekly period, not the minted token amount.
  • The Minter is the contract that mints weekly emissions and hands them to Voter; gauges receive those emissions only after the subsequent voter distribution flow.
