# Add `/cosmos.authz.v1beta1.MsgExec` to the Allowed ICA Host Messages
## Summary
This proposal adds `/cosmos.authz.v1beta1.MsgExec` to the ICA host allowlist.
Osmosis already supports `/cosmos.authz.v1beta1.MsgGrant` and `/cosmos.authz.v1beta1.MsgRevoke` — adding `MsgExec` completes the core Authz set.
## Background
The Interchain Accounts (ICA) module lets a controlled account on one chain perform transactions on another.
In Osmosis today, ICA hosts can grant and revoke permissions, but they cannot **execute** via `MsgExec`. This is the missing link for many automation and delegation patterns.
We’re integrating [Intento](https://intento.zone/) with Osmosis to enable advanced interchain flows — e.g. DCA, token streaming, auto-compounding, and portfolio rebalancing. Intento executes these flows self-custodially via ICAs, without third-party smart contracts or custody.
### Why `MsgExec` Matters
- **Enables secure delegation inside ICA** — allowing a hosted ICA to run batched, permissioned actions on behalf of a user.
- **Improves efficiency** — one hosted ICA can serve many users, reducing fee overhead and infra complexity.
- **Preserves self-custody** — flows enforce strict granter verification: the `MsgExec` signer must be the flow owner.
This doesn’t introduce new powers for ICAs beyond what regular accounts already have — it simply allows ICAs to use an existing, widely-tested message type.
We’ve already validated `MsgExec` in Osmosis testnet for:
- **tokenstream.fun** streaming flows
- **StreamSwap** contract calls
## Current Supported Authz Messages in ICA
- `/cosmos.authz.v1beta1.MsgGrant`
- `/cosmos.authz.v1beta1.MsgRevoke`
_(plus others like MsgSend, MsgTransfer — see [Osmosis ICA host params](https://lcd.osmosis.zone/ibc/apps/interchain_accounts/host/v1/params))_
`MsgExec` lets an authorized account execute transactions granted via Authz.
## Proposal Details
**Add to ICA Allowlist:**
- **Message** : `/cosmos.authz.v1beta1.MsgExec`
- **Function** : Executes any messages previously authorized by the granter.
### Benefits
1. **Parity with other chains** – Neutron, Cosmos Hub, and Injective mainnets already allow this.
2. **Completes Authz support** – grant, revoke, and execute.
3. **Enables advanced automation** – critical for complex cross-chain integrations.
### Risks & Mitigation
- **Complexity** – More allowed types can increase risk, but:
## Implementation Plan
1. **Testnet** – ✅ [Proposal #262 on Osmosis testnet](https://www.mintscan.io/osmosis-testnet/proposals/262) submitted and validated.
2. **Mainnet** – Governance proposal for deployment.
## Conclusion
Adding `MsgExec` to the ICA host allowlist is a high-utility improvement that aligns Osmosis with other IBC chains and unlocks new automation capabilities for integrators.

Looks good, will vote yes barring any technical concerns from the main Osmosis code contributors. More usecases is better!

We run validators for both Osmosis and Intento. We will be voting yes and encourage others to do the same.
