What the data says
USDAI
USDAI is USD.ai's stablecoin — a dollar token backed by loans against GPU and AI-infrastructure collateral, one of the more unusual collateral stacks in the stablecoin set. The contract 0x0a1a1a107e45b7ced86833863f482bc5f4ed82ef is what our scan tracks: $1.2 million of pool liquidity as of October 9, 2026 on Arbitrum, trading essentially at its dollar peg.
The honest mechanics: the backing is hardware-collateralized lending — claims on AI infrastructure and the loans against it — which is genuinely different from the treasury-bill or crypto-overcollateralized models most stablecoins use, and carries its own risks (hardware values depreciate and loan books can go bad). The pool here is thin, so redemptions at size route through the issuer's machinery rather than the public market.
RETH
rETH is Rocket Pool's liquid staking receipt — the decentralized alternative in the ETH-staking market: anyone can run a Rocket Pool "minipool" validator with 8 ETH plus RPL collateral, and rETH appreciates against ETH as rewards accrue. The contract 0xae78736cd615f374d3085123a210448e74fc6393 is the canonical deployment; our October 6, 2026 read shows $12.1 million of tracked pool liquidity, with rETH's deeper venues spread across the wider DeFi stack.
The honest framing: rETH's pitch is credible neutrality — a permissionless operator set rather than one company's validators — and the trade-off is the usual one: a smaller, more fragmented liquidity surface than stETH and its own smart-contract surface (minipool mechanics, oracle DAO) instead of a single issuer's operations. The wrapper price is not ETH's price — it floats on its own exchange rate and has traded at discounts in stress.
FAQ
Which is bigger, USDAI or RETH?
By tracked market cap: USDAI (Arbitrum) measures $346.15M and RETH (Ethereum) measures $1.00B — dated snapshots, not a live feed.
Which is safer, USDAI or RETH?
On the contract checks we publish: USDAI (Arbitrum) grades B and RETH (Ethereum) grades B. A grade is a structural check on the contract, not a promise about the asset.
How have USDAI and RETH performed over the shared window?
Between 2026-09-21 and 2026-10-16T21:15:32, the measured snapshots show USDAI at −0.02% and RETH at −1.84%.
The grade column is the one CMC's compare page cannot print — our grade is computed from the contract itself (mint/freeze authority, liquidity, holder concentration). Changes are measured over the shared window stated on the chart, 2026-09-21→2026-10-16T21:15:32; a token with fewer measured points measures a shorter span inside it.
