Summary
LlamaRisk supports onboarding PAXG to the Aave V4 Global Dollar Hub as a collateral-only reserve in the new Gold Spoke, at a 75% Collateral Factor with a 6.50% maximum dynamic liquidation bonus, with borrowing of the asset disabled through a zero draw cap and a conservative add cap, and with USDG as the spoke’s borrow side.
Support is conditional on the proxy admin moving behind a timelock, which Paxos confirmed is being implemented with rollout expected the week of August 17, 2026. The proposal also enables native USDG as a borrowable reserve on the Pendle Spoke.
PAXG is the regulated gold token of Paxos Trust Company, National Association, a national trust bank supervised by the Office of the Comptroller of the Currency since its conversion from a New York limited-purpose trust charter on December 12, 2025. Each token is title to one troy ounce of allocated London Good Delivery gold, with roughly 452,355 tokens outstanding against a reserve KPMG attested one-to-one as of June 2026.
The risk surface divides into four parts. $9.1 million of PAXG exits into USDG inside a 2.64% price impact, and the dominant on-chain pool rests on a single liquidity provider. PAXG is to be priced at gold spot through a Chainlink XAU/USD feed. The gap between the token’s own price and gold has been analysed: it stayed within 1% on 97.7% of days and reached a 2.0% premium and a 1.05% discount at its extremes. There is a recent audit attestation, a million-dollar bug bounty, and a cross-chain route verified on-chain whose worst-case unbacked mint is rate-limited at 4,440 PAXG per day. The upgrade path carries no timelock today, and freeze, wipe, and mint authority concentrate in the same keys. The custody arrangement behind them was disclosed under a non-disclosure agreement and viewed as sufficient by LlamaRisk, and reserve backing is attested monthly.

Aave V4 Global Dollar Hub Parameters
Aave V4 Specific Parameters
We recommend adding PAXG as a collateral-only asset to the new Gold Spoke. In parallel, to avoid additional governance proposals, we also propose enabling native USDG as a borrowable reserve on the Pendle Spoke with a 4,000,000 USDG Draw Cap.
Dynamic Liquidation Bonus Configuration
As a non-crypto open-market spoke, it merits more conservative liquidation restoration parameters. Draw Caps will be set conservatively to reflect the Gold Spoke’s still-developing borrow-side liquidity profile.
Spoke-level liquidation parameters:
| Parameter |

Rationale |
| targetHealthFactor |

Open-market non-crypto collateral dynamics require more conservative post-liquidation restoration than that of other Global Dollar Hub Spokes. |
| healthFactorForMaxBonus |

Lower trigger avoids overpaying incentives too early while still reaching max LB before the deficit zone. |
| liquidationBonusFactor |

Matches the Main Spoke baseline and preserves V3-equivalent Gold correlated asset bonus at HF~1 with a 1.25x max LB cap. |

Oracle
List PAXG against the Chainlink XAU/USD price feed, pricing the token at underlying gold spot with no CAPO growth-ceiling wrapper. PAXG carries no monotonic exchange-rate growth for a cap to bound, so a CAPO adapter is not recommended. The accepted risks are a sustained token-level dislocation priced at full gold spot and the feed’s weekend staleness. The liquidation parameters set at any future collateral-enable phase must absorb that envelope rather than assume a continuously updating reference.
