🚀 What’s New

Introducing new Watch-Only Wallets

We are excited to introduce a new wallet type: Watch-Only Wallet for exchanges, asset managers, and institutions. Admins and Owners can easily import and monitor a single wallet address or a list of Externally Owned Addresses (EOA) without losing custody of private keys, and safely track and monitor wallet activity.

Key Capabilities:

• Create Watch-Only wallets: Use the Watch-Only Wallet API to gain complete visibility into wallet activity without operational overhead or key management.
• Import existing addresses: Use the Import Address API to import addresses from existing wallets and monitor asset transactions in one place.
• Receive Webhook notifications: Get real-time successful and periodic webhook notifications for incoming deposits and outgoing transactions in your Watch-Only wallets.
• Other supported actions: You can also archive/unarchive, generate reports, and explore wallet balance details using supported API requests.

Refer to the Watch-Only wallet guide to explore in detail.

IP Whitelisting and HMAC Security for API Keys

With this release, you can now restrict API key usage to specific IP addresses using Source IP and Express Server IP whitelists, ensuring only requests from approved sources can access your environment. Additionally, you can enable HMAC authentication with SecureAPI on top of IP whitelisting for an extra layer of security, protecting API keys from unauthorised access and credential theft.

Refer the the following guides to implement the improvements:

1. The Manage my API Key guide to add addresses to local whitelist and disable/re-enable address.
2. The How to setup HMAC secret key and boost IP whitelisting security with SecureAPI guide to configure and implement HMAC secret to your Liminal Vaults account.

Transaction Rescan API to Retrigger Sync

With this release, you can initiate a transaction rescan either by passing either transactionHash or sequenceId to update wallet balance seamlessly. You will receive the respective Send and Receive transaction webhooks upon resync when a transaction rescan is successful.

Refer to the Transaction Rescan API reference guide to learn how you can retrigger transaction sync manually and keep the transaction history updated.

Introducing Portfolio for Liminal Vaults Mobile

With this release, the Liminal Vaults Mobile app supports a new Portfolio page to provide a comprehensive visual dashboard of your wallet holdings and balances. You can now view key asset metrics, track portfolio balances, and send or receive assets instantly - all in one place.

Refer to the Mobile Portfolio section to learn more.

New Manual Balance Sync Support

With this release, users can now manually sync wallet balances to reflect the latest on-chain state in real-time, enabling greater control and visibility for timely, accurate updates. Manual Balance Sync allows you to view the current asset and total wallet balances directly in the wallet details.

Key capabilities:

• Supported wallets: Cold, Warm, Hot Deposit, and Withdrawal wallets.
• Supported chains: Solana (SOL), Tron (TRX) , and EVM chains only.
• Benefit: Effortlessly refresh asset balances without waiting for background syncs or webhook notifications

Refer to the Manual Balance Sync guide to learn how it works.

Add Custom Token to Local Whitelist

Organisations can now add, verify, and manage custom tokens in their local whitelist to extend token support in their protocol setup. Smart contract validation via Coingecko ensures accuracy, transparency, and compliance, while globally whitelisted chains remain visible in settings.

Refer to the Add Custom Tokens section to learn more.

New: Kaia Blockchain Support

Disable Compliance Alerts Feature for Address Screening

Owners can now Ignore Compliance Alerts during destination address screening protocols with integrated app support from Cube3 and Cyvers. This feature provides organisations with the control and flexibility to focus on cyber and fraud risks while retaining compliance visibility.

Key capabilities:

• Excludes compliance scores from total risk calculation: The risk score is only based on scam, fraud, and cyber categories.
• Maintains visibility: Compliance scores remain visible for address whitelisting, transaction initiation, approval, and signing.
• Faster transaction flow: Transactions that are normally blocked by compliance alerts now return 201 OK via the Create Transaction Request API reference.

Refer to the Disable Compliance Alerts guide to learn how to implement the feature.

✨ Improvements

Liminal Vaults supports the following improvements with this release:

Improved Transaction History with Side Panel

With this release, the History page is enhanced with a new Transaction Side Panel for each transaction. It provides a detailed view of the transaction’s history, compliance checks, status, and sub-status — ensuring a clear and transparent audit trail of all financial movements.

Support for Backdated Holding Statements

With this release, we have enhanced the Holdings Report with Backdated Snapshots, capturing the state of all assets on a specific past date and their historical USD values using the day’s average exchange rate. Snapshots are generated at 11:45 PM UTC, enabling accurate reconciliation and auditing of past holdings.

Refer to Reports in the Transactions guide to learn more.

BTC Decimal Precision Increase

Increased BTC decimal precision from 5 to 8 decimal places, enabling more accurate and granular transaction handling for high-value assets. All other supported assets now maintain precision up to 6 decimal places for consistent accuracy across transactions.

Memo Data Support in Webhooks and On-Chain Transactions

Added memo data to Webhooks and on-chain data via the raw data field for consistency with API responses for Wallet [v2] wallet transactions. This enhancement also extends memo support in the Send transaction flow and payload information for outgoing transactions.

Refer to the following Wallet [v2] guides to check the payload parameter:

1. The Webhook Payload Paramters in the Receive transaction webhooks guide.

Asset Pricing improvement via name & Contract Addresses

With this release, asset prices are fetched based on name and contract address rather than symbol ensuring accurate USD price reporting for asset holdings.

Enhanced Report Downloading Performance

We’ve enhanced report downloading performance for Backdated Holdings Statements and Transaction History Reports in both itemised CSV and PDF formats, ensuring faster and more efficient downloads.

Faster UTXO Withdrawal Broadcasts

Withdrawal transactions for UTXO chains are now upgraded to ensure that 99.9% of approved withdrawals are successfully broadcast to the blockchain network within one minute to improve reliability and transaction speed.

Improved TRON Token Consolidation

Consolidation is now optimised to reserve funds for TRON token consolidations, reducing unnecessary transaction sprays and repeated re-consolidation.

Default Wallet View access for Admins

With this release, Admins in Liminal Vaults have View access to all wallets by default, including smart consolidation wallets. The improvement in consistency and flexibility makes it easier for Admins to monitor and view all wallet activity.

Updated isArchived Data Type in Webhooks
