This proposal will update the expired client on channel-5309 between dungeon-1 and neutron-1

Upgrade dungeon-1 to v9.0.0 at height 19252800 (est. Mon 2026-08-17 ~16:00 UTC). Dep bumps: cosmos-sdk 0.53.7, ibc-go 10.7.0, PFM 10.6.0, wasmd 0.60.8 (wasmvm 2.3.4). New: IBC rate-limiting module (ibc-apps v10.1.0) wired as ICS4Wrapper for transfer+PFM. Sets a 5% minimum validator commission floor and raises sub-floor validators. Binary: static linux/amd64, sha256 aa1a32201d4bfc3161130759c309d9e3314936314c8a87b7313110d3d6dc190c. Tested: full scripted v8-to-v9 upgrade battery plus a real-mainnet-state fork test (gov upgrade, contract execution under wasmvm 2.3.4, commission floor, rate-limit, IBC clients all verified).

Add the Kosmic Monsters CW721 collection to Dungeon Marketplace accepted contracts so KMON can be listed and traded for DGN.

Add the Dungeon Import (DIMP) CW721 contract dungeon17kw5c9688alx6ynrl9ca0muscnazxzx0ef9uk7gkasn9p8l8z37q26whg5 to marketplace accepted_nft_contracts so imported Hub NFTs reminted on dungeon-1 can be listed and traded on The Hoard.

This proposal upgrades dungeon-1 to v8.0.0 and adds the Hyperlane core and warp modules required for Dungeon-owned ETH and Solana bridge routes. The upgrade prepares the chain for Hyperlane core deployment and DGN Warp Route testing. It does not immediately open uncapped production bridge liquidity.

Software upgrade to v7 binary at height 15,400,000. Bumps cosmos-sdk to v0.53.6, wasmd to v0.60.0 (cosmwasm_2_0 capability), ibc-go to v10 (removes deprecated 29-fee). Unblocks BTC bridge mainnet deployment. Tested 2026-05-24 v6 to v7 on isolated testnet, chain advanced cleanly, upgrade marker applied. Submitted via dungeond CLI (not cosmjs) to dodge the Plan.Time 1970 issue that broke prop #32. Expedited.

Retry of failed prop #32. Identical content; submitted via dungeond CLI to bypass the cosmjs Plan.Time bug. What changes at upgrade height 15199186: 1. x/globalfee minimum gas price set to 0.01udgn. 2. Fee-exempt addresses: - Admin/treasury: dungeon13x4pynlp86prhcmtns742kgsgu7pjtzj72eycc - BTC relayer: dungeon1dflpa6dnpkn5ft4tyzkpwdhvz6l7wng06qn665 3. Block time tuned to 1500ms. 4. Dead IBC channel JSON config files removed. Upgrade height ~3.7 days from submission (3-day vote + ~17 hr binary distribution buffer). Original prop #32 targeted height 14897749 (~5h from now) — too tight to accommodate voting. Prior tally on prop #32: 203,745,934,428,765 YES / 0 NO / 0 VETO.
