Governance Proposal: Enable usdc.noble
on Regen Ledger
Title:
Add Noble-issued USDC (usdc.noble
) to the Regen Ledger currency allowlist
Summary:
This proposal enables the use of Cosmos-native USDC — specifically usdc.noble
— on Regen Ledger by adding it to the currency_allow_list
. This unlocks USDC for use in the Regen Marketplace and future IBC-native flows, enabling dollar-denominated ecocredit purchases and broader ReFi utility.
Context & Motivation
- Noble is the official Cosmos-native issuance chain for Circle USDC
- Native USDC already circulates in Cosmos via IBC (e.g., Osmosis, dYdX, Neutron)
- Regen currently only supports
axlUSDC
, which is a custodial bridge asset - Enabling
usdc.noble
improves UX, reduces trust assumptions, and positions Regen to settle real-world ESG payments with native stables
Technical Details
-
IBC Channel Required:
Regen ↔ Noble (to be established with relayer support) -
Initial Denom:
"usdc.noble"
(IBC hash will be updated once the channel is live, e.g.ibc/7A3...
) -
Marketplace Config Update:
Add tocurrency_allow_list
inx/marketplace
:
{
"denom": "usdc.noble",
"display_denom": "USDC",
"decimals": 6,
"enabled": true
}
-
Frontend Coordination:
Regen Marketplace frontend will be updated to:- Show USDC as a purchase/retirement option
- Display balances and denom trace correctly
-
Fee Token (Optional):
Future updates may allow USDC as a transaction fee token (x/feegrant
), pending community discussion
Future Incentive Alignment (non-binding)
-
Follow-up proposals may introduce:
- REGEN/USDC LP incentives (on Regen or Osmosis)
- Offset campaigns funded in USDC
- Eco-credit retirements matched or subsidized in stables
Relayer Coordination Needed
This proposal assumes an IBC channel between Regen and Noble will be established. Once passed, relayer support will be needed to activate the channel and register the usdc.noble
denom on Regen.
Interested relayers (e.g., Strangelove, Notional, others) are invited to coordinate in Regen Discord or governance forums.
Governance Impact
- Yes: Adds
usdc.noble
to Regen’s currency allowlist, enabling Cosmos-native stablecoin flows and supporting real-world ESG use cases - No: Regen continues to rely on bridged custodial tokens (
axlUSDC
), with reduced credibility and reach
