Arc CCTP v2 Transfer

Note (dated 2026-08-04): a chain composes independent computations performed in an analytical order. No step's output is carried into the next step by the execution model; each step computes from its own declared inputs. This is true of every chain on this site, including chains whose per-step copy below reads as a data handoff.

W-G chain. Validate CCTP v2 cross-chain USDC transfer — fires when ≥2 Arc fit dimensions score >0.

Export Artifacts
Download the §4 chain definition artifact (hash-anchored composite JSON) or the §13.11 W3C Verifiable Credentials view. Both derive from the chain definition — no new hash is minted. Available after hash computation.

Ask your agent

Copy this paragraph into Claude, OpenClaw, or any MCP-aware agent to run this whole workflow on the server and check one field that answers a real question.

Question: Treasury queued a burn-and-mint to a chain missing from the operations runbook. What does the transfer check say about that destination?
Run the AINumbers MCP tool `run_chain` with {"chain":"arc-cctp-transfer"} and read `art-47-arc-cctp-transfer.verdict`.
Re-run with `inputs` for `art-47-arc-cctp-transfer`, reusing the values that result echoed, with `dest_domain` set to "moonbeam". Compare the same field.
Verify: call `verify_execution_hash` (https://mcp.ainumbers.co/mcp) with `claimed_hash` set to `composite_execution_hash` and the full `composite_artifact`.
Ledger, for a human re-check: https://ledger.ainumbers.co/
PII rule: send synthetic or anonymised inputs only. The MCP server runs these kernels and logs no payloads.
