Liminal has released the production environment version [v1.2.12] of Liminal Express. This update introduces address screening functionality to the create transaction requests API for Hot withdrawal wallets. Additionally, webhooks will now include 2 new objects - transactionStatus and blockConfirmationData as part of our ongoing efforts to improve transaction status visibility across different stages of a transaction.
Create Transaction Requests API
Depending on the threshold set by you for Address Screening, Liminal will block transactions initiated through the create transaction requests API with a 422 error response if any of the destination addresses has a risk score equal to or above the set minimum severity threshold.
To understand what is address screening, see complete guide here.
We recommend you keep Address Screening switched on for Hot Wallets with minimum severity setting as High/Critical.
⚙️ Real time block confirmation updates with Periodic Webhooks
For incoming transactions (Type: Receive) you can now receive periodic webhooks starting with the first block confirmation for Bitcoin, Ethereum and ERC-20 tokens. Additionally, the webhook response will now include a new transactionStatus and blockConfirmationData object.
For a complete guide on how to start receiving periodic webhooks and how you can configure these into your application see Periodic Webhooks
