Module nash_protocol::protocol::asset_nonces

Retrieve current asset nonces from Nash server. Asset nonces allow the smart contract to reason about whether a payload such as a sync state or fill order request is valid in relation to previous activity. Generally, only payloads with a higher nonce than the last seen nonce for an asset are considered valid. For fill order payloads, the nonce must equal the current nonce.

Structs

AssetNoncesRequest

Retrieve asset nonces from Nash server. Asset nonces increment over time with the property that orders and state signed with older nonces is considered invalid by smart contracts on Ethereum and NEO.

AssetNoncesResponse

Response contains a HashMap which connects the symbol of an asset with its associate nonce.

Functions

asset_nonces_canonical_string

Generate canonical string for on request to get asset nonces
