🆕 New Features

Introducing Self Serve Firewall Manager on Vaults

Vaults now supports self-serve Firewall Manager for v2 wallet transactions. This helps users manage firewall configuration for their organisation directly from Vaults, resolving the earlier requirement of reaching out to the Liminal support team to configure the firewall.

Here are the supported capabilities:

1. You can configure the firewall transaction policies, including Transfers, Transaction Risk (AML) and Travel Rule policies.

2. Available on Vaults from Settings > Firewall.

3. Supported firewall configurations: You can add, update and delete operations for Send and Receive rules.

4. Firewall Policy Control: Owners and Compliance team members need to review and approve the Firewall policy. It is implemented and added to the firewall configuration once approved.

   

Introducing Cross-Chain Stable Swap

Vaults now supports the Stable Swap feature enabling secure and institutional cross-chain stablecoin transactions via LiFi. This allows users to exchange stablecoins across the supported protocols with real-time route discovery, asset price quotes, risk screening and firewall approval. This helps institutions to balance liquidity among different chains.

The feature supports the following capabilities:

1. Supported chains and tokens:
   1. Ethereum, Polygon, BNB and Base chains.
   2. USDC and USDT tokens.
2. Security, route and policy measures:
   1. Supports destination address and smart-contract whitelisting.
   2. Token Allowance: Supports token allowance to validate the wallet, token, swap provider for the contract and token amount to enable swap. The allowance helps to keep the session active for the valid token.
   3. Real-time Routing: Supports fetching real-time quote for the configured swap including the bridge execution route, estimative output, gas fee and slippage percentage. The quote stays valid for 60 seconds.
3. Complete swap transaction flow: Supports transaction: Initiation → Initiator Quorum → Firewall Quorum → Mobile Signing → Broadcast.
4. Supports transaction history record and reporting: Vaults records the swap transaction in the transaction history, audit logs and transaction records.
