ATMC Stablecoin Allocation — Morpho Blue Gold-Collateralized Credit Market

General

1

This proposal recommends a pilot allocation of idle USDC from the ATMC stablecoin balance into the Trinity Gold USDC Vault on Morpho Blue. The vault offers yield on USDC deposits backed by overcollateralized gold-linked tokens (GVLT), providing non-correlated diversification from the current STEP portfolio of tokenized US Treasuries.

Motivation:

The ATMC currently deploys stablecoins primarily into tokenized Treasury instruments (BUIDL, USDY, USTBL). While these are low-risk, they concentrate exposure in USD-denominated government debt. A gold-collateralized credit market on Morpho Blue provides:

1. Non-correlated hard-asset exposure (gold vs. Treasuries)

2. On-chain collateral transparency (no off-chain custodian dependency)

3. Conservative risk parameters (62.5% LLTV vs. 77-90% typical on Morpho)

4. Native Arbitrum deployment (no bridging risk)

5. $531M+ in posted collateral — 115,281 GVLT at current oracle price of $4,610/GVLT

Specification:

- Pilot allocation: $5M USDC from idle ATMC stablecoin balance

- Deployment: Trinity Gold USDC Vault (MetaMorpho ERC-4626) on Arbitrum One

- Duration: 90-day evaluation period with monthly reporting

- Exit: Withdraw anytime — no lock-up, standard ERC-4626 redemption

Risk Parameters:

- LLTV: 62.5% (borrower must maintain >160% collateralization ratio)

- Oracle: Immutable adapter using Chainlink XAU/USD + USDC/USD with ±3% peg validation

- Liquidation: Standard Morpho Blue liquidation module — permissionless, MEV-aligned

- Timelock: 72 hours (259,200 seconds) — confirmed on-chain

- Withdrawal: Anytime, no lock-up, standard ERC-4626

Vault: Morpho

Comparable precedent: STEP 1 allocated to BlackRock BUIDL and Ondo USDY — both tokenized off-chain assets. This proposal offers the same yield thesis with fully on-chain, oracle-transparent gold collateral. We are very excited and take great pride in being a part of the Arbitrum Community. Thank you to you all and we are grateful to be a part of Arbitrums expansion.

Wanted to add some broader context on why gold-collateralized lending deserves attention from the Council right now.

Gold has outperformed every major asset class in 2026. The dollar is facing structural headwinds — persistent inflation, expanding fiscal deficits, and growing uncertainty around monetary policy. In that environment, gold isn’t just a hedge — it’s becoming the baseline store of value that the dollar used to be.

A USDC lending market backed by gold-linked collateral gives the Arbitrum treasury something it doesn’t currently have: yield that’s grounded in a 5,000-year-old monetary asset, not recursive crypto leverage. That’s a fundamentally different risk profile than the alternatives.
