// 2 required DVNs: every required DVN must attest before a packet verifies, so a single
// compromised verifier cannot forge an inbound message. Both are live and non-deprecated
// per the LayerZero DVN metadata API (verified 2026-10-15):
// Celo Nethermind 0xdd7b5e1db4aafd5c8ec3b764efb8ed265aa5445b
// XDC (EID 30365) Nethermind 0x1294e3347ec64fd63e1d0594dc1294247cd237c7

// | jq '.xdc.dvns | to_entries[] | select(.value.canonicalName=="Nethermind")'
