Re-evaluate

Sub-claim "CCTP uses a burn-and-mint mechanism where USDC is burned on …": 0% covered — No gathered source describes CCTP or its burn-and-mint mechanism. S1 discusses general USDC instant settlement, not cross-chain burn/mint. S2 is unrelated.

Re-evaluate

Sub-claim "CCTP employs a Token Messenger contract on each domain that …": 0% covered — No gathered source mentions Token Messenger contracts or CCTP's architecture.

Re-evaluate

Sub-claim "CCTP uses a cross-chain messaging protocol with attestation …": 0% covered — No gathered source discusses cross-chain messaging, attestation, or CCTP's protocol.

Re-evaluate

All three sub-claims are completely uncovered by the gathered sources. However, none of the skipped sources appear to address CCTP specifically; they cover unrelated topics like x402, stablecoin payouts, and general crypto news. Therefore, buying additional sources would not fill the specific gap and would not be frugal.

Sufficiency

Final coverage assessment — The gathered sources do not mention CCTP, burn-and-mint mechanisms, Token Messenger contracts, or cross-chain messaging with attestation. They only discuss USDC settlement onchain and a Coinbase blog post unrelated to CCTP.

§ IIThe reading0 cited

Lowconfidence— no citation passed the evidence gatedeep researchpreview plan 3/3 claimsportfolio 2/2 · evidence 0%

The provided sources do not contain information about CCTP, cross-chain USDC transfers, or the mechanisms described (burn-and-mint, Token Messenger, attestation). S1 only discusses USDC onchain settlement generally, and S2 is a Coinbase response to a Wall Street Journal article. Therefore, none of the subclaims can be supported by these sources.
