Order Execution
After a user order is created, then the corresponding eth-flow contract order will be traded in CoW Swap.
The contract order uses EIP-1271 signatures.
The signature can be empty, since all information needed to verify the order can be found onchain.
Signature verification in a settlement works as follows:
- 1.The order digest is computed as part of the settlement process and is the message that is assumed to be EIP-1271-signed by the eth-flow contract. The digest is used to retrieve the owner and the validity from the order mapping.
- 2.The order validity is checked against the current timestamp.
- 3.The owner must be valid (should be set and not invalidated).
If all verification steps succeed, the order can be traded.
