Content

This release rewrites the economics of the chain. v7 is built around a new tokenomics stack: x/inflation shapes how the network mints over time, and x/tieredrewards gives stakers a richer, tier-based reward system with a rewards pool that can backstop base yield when block fees alone fall short.

The plan name is v7 for mainnet and v7.1.0-testnet for testnet.

x/inflation

• Time-based inflation decay: after a configured decay epoch start height, the rate applied in minting is reduced using a monthly decay model (governed decay_rate), on top of the normal Cosmos x/mint calculation.
• Supply and burns: module params support max supply (enforced in BeginBlocker) and burned addresses whose balances are treated as out of circulation for that check.

Details in ADR-007

x/tieredrewards

• Tiers define rules such as minimum lock, exit delay, bonus APY (capped for safety), and close-only tiers for wind-down.
• Stakers can manage positions (including flows such as exit with delegation back to the owner) and claim rewards, including batch claims for multiple position IDs in one tx.
• Base-rewards top-up: if fees to stakers (after community tax) are below a governance TargetBaseRewardsRate, the module tops up staker rewards from a rewards_pool, allocated with consensus voting power, so “base” staking yield can be floored even when fees are light.
• Bonus rewards are integrated with validator events (e.g. unbonding/slashing) so accrual and claims stay consistent across lifecycle changes; redelegation slash handling was tightened so pending rewards are claimed where needed.

Other changes

Other v7 changes focus on hardening and maintenance: major dependency upgrades (Cosmos SDK v0.53.4, IBC v10.5.1, RocksDB/cronos-store), a CometBFT security patch, and semver/module-path alignment. The release also improves developer operations (local-chain scripts, Makefile, lint/CI cleanup) and fixes important edge cases in nft-transfer/IBC NFT handling, versiondb integration, and CLI/query coverage. Overall, outside tokenomics, this is a strong stability and platform-quality release.
