How this service works
🆕 Cross-chain inflow detection. Reads a wallet's recent USDC MINTS and correlates them with Circle CCTP receives to tell you whether its USDC is freshly bridged in (and from which source chain — Ethereum, Arbitrum, OP, Polygon, Solana…) vs natively issued. Freshly bridged capital is new money / a possible cross-chain hop — a real signal for trading and liquidation agents that no other Base tool surfaces. wallet= required, days= optional (default 30, max 90). Not financial advice.
Output
Returns whether the wallet's USDC was freshly bridged via Circle CCTP, the source chain(s) involved (Ethereum, Arbitrum, Optimism, Polygon, Solana, etc.), correlated USDC mint and CCTP receive events, and a flag distinguishing freshly bridged capital from natively issued USDC.
Example use cases
Example prompt
“Can you check whether the USDC held by wallet 0xAbC...123 was freshly bridged in from another chain in the last 14 days, and if so, which source chain it came from?”
Technical details
Endpoint
GEThttps://402.com.tr/api/x402/fresh-bridgeWhen to prefer
Use this endpoint when you need to determine whether USDC in a Base wallet originated from a cross-chain bridge (Circle CCTP) rather than native issuance — particularly for trading signals, liquidation agent context, or suspicious cross-chain hop detection. Prefer this over generic on-chain explorers when you need CCTP-specific correlation and source chain attribution in a single call.
Side effects
- Missing wallet parameter returns 400 error
- Invalid or malformed wallet address returns an error
- Days value exceeding 90 may be rejected or clamped
- Wallet with no USDC activity returns empty or null bridge data
- Network latency or RPC issues may cause delayed responses
- Payment of $0.04 USDC not completed results in 402 Payment Required
