Modules on the Hub - Cosmos Docs

This page lists the modules that make up the Cosmos Hub application in gaia v28.3.1, taken from app/modules.go in the release, so operators and builders can see which messages and parameters exist on chain. Each module’s current parameters come from the query shown next to it (all queries below ran against mainnet on 2026-10-15). Module documentation is kept with the module’s source. The Hub pages only cover what the Hub configures differently. Three modules that older lists mention are not in v28.3.1: the interchain security provider (removed in v28.0.0, as the Hub no longer hosts consumer chains), ICS-29 fee middleware, and the globalfee module (replaced by the fee market). The gaiad q upgrade module-versions query still reports capability and crisis entries from earlier versions. Neither has state or messages any more.

Cosmos SDK v0.53.4

Module	What it does on the Hub	Parameters
auth	accounts, signature verification, memo and signature limits	`gaiad q auth params`: `max_memo_characters: 512`, `tx_sig_limit: 7`
vesting	vesting account types	none
bank	balances, transfers, denom metadata; gaia wraps it to enforce send restrictions	`gaiad q bank params`: `default_send_enabled: true`
staking	validators, delegations, unbonding	`gaiad q staking params`: 180 validators, 21 day unbonding, 5 percent minimum commission
distribution	rewards, commission, community pool	`gaiad q distribution params`: `community_tax: 0.02`
slashing	downtime and double sign penalties	`gaiad q slashing params`: window 10000, 5 percent double sign, 0.01 percent downtime, 10 minute jail
mint	ATOM issuance	`gaiad q mint params`: inflation 7 to 10 percent, goal bonded 67 percent
gov	proposals, deposits, votes; gaia wraps it to require 1 ATOM staked to vote	`gaiad q gov params`: 500 ATOM deposit, 7 day vote, 40 percent quorum
upgrade	coordinated software upgrades	`gaiad q upgrade plan` (empty when none is scheduled)
evidence	double sign evidence handling	none
feegrant	fee allowances from one account to another	none
authz	message authorizations between accounts	none
params	legacy parameter subspaces; only `param-change` proposals still use it	`gaiad q params subspace staking MaxValidators`
consensus	block size, gas and evidence limits	`gaiad q consensus params`: `max_bytes: 2000000`, `max_gas: 75000000`
genutil	genesis transactions	none

ibc-go v10.7.0

Module	What it does on the Hub	Parameters
ibc core	clients, connections, channels, and the IBC v2 client and channel keepers	`gaiad q ibc client params`: `allowed_clients: 07-tendermint, 08-wasm`
07-tendermint	light client for Cosmos SDK chains	per client
08-wasm	Wasm light clients, used for IBC v2 counterparties such as Ethereum	`gaiad q ibc-wasm checksums` (4 checksums)
transfer	ICS-20 token transfer, classic and v2	`gaiad q ibc-transfer params`: send and receive enabled
interchain accounts	host (any message allowed) and controller	`gaiad q interchain-accounts host params`: `host_enabled: true`, `allow_messages: ["*"]`
packet forward middleware v10.6.0	multi hop transfers through the Hub	none
rate limiting v10.1.0	per channel, per denom transfer quotas	`gaiad q ratelimit list-rate-limits` (7 limits)
callbacks	contract callbacks on packet lifecycle, classic and v2	none

The transfer application is wrapped as transfer, then callbacks, then rate limiting, then packet forward middleware on the classic stack. On the v2 stack it is wrapped as transfer, callbacks, and rate limiting (app/keepers/keepers.go).

CosmWasm (wasmd v0.60.9)

Module	What it does on the Hub	Parameters
wasm	smart contracts	`gaiad q wasm params`: `code_upload_access: Everybody`, `instantiate_default_permission: Everybody`

The gaiad q wasm list-code query returned more than 100 code IDs on 2026-10-15 (the query paginates). Contracts can call the tokenfactory module through its wasm bindings.

Hub specific and third party

Module	What it does on the Hub	Parameters
liquid	liquid staking: tokenized shares, caps, account locks	`gaiad q liquid params`: 25 percent global cap
tokenfactory	permissionless `factory/...` denoms	`gaiad q tokenfactory params`: 10 ATOM creation fee
feemarket	dynamic gas price with a 0.005 uatom floor	`gaiad q feemarket params`
metaprotocols	validated extension data on transactions	none

The authoritative list for any release is the module manager in app/modules.go at that tag, and the versions the chain has stored:

gaiad q upgrade module-versions --node https://cosmos-rpc.publicnode.com:443

The output lists every module name with its consensus version. A module in the table above with no entry means it has no versioned state (vesting, genutil). An entry with no module above is a leftover from an earlier release (capability, crisis).

Parameter change proposals to change any value above.
Liquid staking, Tokenfactory, and Fee market for the Hub specific modules.
