Cross-Chain Message Security
These concepts help cross-chain systems wait for settlement, coordinate relayers, prevent duplicate execution, and manage destination timing.

Destination Execution Delay
A destination execution delay is a configured pause between accepting a cross-chain message and executing its action on the receiving network.
Relayer Quorum Threshold
A relayer quorum threshold is the minimum number or weight of independent relayers required to approve delivery of a cross-chain message.
Replay Protection Nonce
A replay protection nonce is a unique sequence value that prevents the same cross-chain instruction from being accepted more than once.
