"Matters" is our weighting of how much each dimension typically drives a real allocation decision. Sort any column to re-rank the tradeoffs by what matters to you.

The short answer

USDC scores higher on safety (91 vs 61), driven mainly by collateral quality and disclosure. USDC has deeper tracked liquidity ($20.99B), which is what determines whether you can exit at size. USDC currently earns up to 37.30% — remember that any rate above the T-bill yield is payment for a risk.

If both are fiat-reserve tokens, note that holding both is not diversification: they share the same short-dated Treasury and banking exposure. Genuine diversification means mixing collateral structures.

Which one fits your goal: KEI or USDC?

Capital preservation over everything else.

For park cash safely, USDC is the better fit over KEI.

  • Safety score 91 vs 61, with collateral rated 95/100.
  • Current peg deviation -0.012% against 0.000% for KEI.
  • USDC has 1 recorded depeg event(s) — read them before sizing up.

Concentrating in one issuer is a single point of failure regardless of score. Split across collateral structures.

Are KEI and USDC trading at $1.00 right now?

Has KEI or USDC ever depegged?

+

KEI: no material depeg recorded in our incident set. USDC: worst recorded deviation −12.0%. Past peg behaviour under stress is the single best available proxy for how a token trades in the next crisis.

Which is better for large institutional size, KEI or USDC?

+

For block size the constraint is exit liquidity and primary redemption, not headline supply. USDC shows deeper on-chain liquidity at $20.99B versus $79.9K. Combine that with the redemption channel — KEI: market-only; USDC: direct — and size trades against the primary window rather than the order book where possible.

Can I earn yield on KEI or USDC?

+

USDC currently shows the higher rate at 37.30% via accountable · Ethereum, against no tracked rate for KEI. Neither token pays interest by holding it in a wallet: the yield comes from lending, liquidity provision or a wrapped yield-bearing version, each with its own counterparty and contract risk.

Which chains support both KEI and USDC?

+

Both are deployed on 1 shared network, including Hyperliquid L1. KEI spans 1 chains in total and USDC spans 121. Bridged supply on a chain is not the same as natively issued supply, and it usually carries the bridge's risk rather than the issuer's.

What does it cost to switch from KEI to USDC?

+

Budget three components: the current price spread of roughly 1.2 bps, swap or venue fees, and slippage against available depth ($79.9K for KEI, $20.99B for USDC). For meaningful size, redeeming with the issuer and minting the other side is often cheaper than a secondary-market swap.

Is KEI or USDC regulated?

+

KEI is issued from Not documented with none; USDC is issued from United States (NYDFS / MiCA) with monthly. Regulatory status varies by your own jurisdiction and by whether the token is offered under a specific stablecoin regime, so treat this as a starting point for diligence, not legal advice.
