Find Relevant Records Faster

Version 8.4.0 introduces several improvements to the Compliance Dashboard, giving compliance teams greater control over how transaction and customer information is viewed and managed.

The Compliance Dashboard now lets teams filter tables by asset and date interval and see how many results match. Columns can also be hidden to suit each user's workflow, with preferences preserved across page reloads.

Transaction search now includes beneficiary wallet addresses, providing another way to locate relevant transactions.

Address Book detail views now bring all of a customer's asset accounts together, giving compliance teams a more complete overview of customer activity and associated assets.

Asset tokens also indicate their base chain, making tokens operating on different networks easier to distinguish.

Smarter TRUST Workflows

Incoming TRUST requests now match the beneficiary's name against the registered customer. Compliance teams can configure the matching rules in the dashboard to reflect their firm's requirements.

Transactions to a recipient identified by a wallet address can now be initiated via a unified interface. The system will automatically select the TRP or TRUST or TRUST protocol as required. TRUST setup also obtains the VASP's legal name from the bulletin board, validates access before saving settings and creates a TRP configuration when none exists. Requests for personal information recheck the counterparty's trust status before proceeding.

Expanded Address Ownership Portal Support

The Address Ownership Portal has been expanded to support additional blockchain networks and wallets.

Address ownership proofs now support:

• Optimism
• Arbitrum
• Avalanche
• Gnosis Chain

Phantom can also now be used to sign Solana ownership proofs, extending self-hosted wallet verification to Solana users.

The portal now clearly displays the requested asset and its network before a proof is submitted. This gives users greater context during the verification process and helps reduce the risk of signing a proof for the wrong asset or network.

Stronger Enterprise Access Controls and Audit History

Version 8.4.0 strengthens access controls for enterprise deployments.

Enterprise deployments now enforce role permissions across GraphQL queries, mutations and subscriptions. The Compliance Dashboard also disables actions for users who do not have the required role, helping firms manage who can view data and make changes.

New history views show the events associated with transactions, wallet proofs and counterparty VASPs directly alongside their details. This gives enterprise compliance teams more context when reviewing a record during an investigation or audit.

More Flexible Enterprise Infrastructure

Version 8.4.0 introduces additional deployment options for enterprise infrastructure.

VASPs can now deploy 21 Travel Rule with managed PostgreSQL and external S3 storage, giving infrastructure teams more flexibility to use their existing services and operational tools.

HAProxy supports an IP allowlist for restricting ingress traffic to approved addresses. Published container images are now signed with cosign, allowing deployment teams to verify their signatures.

Email Improvements

Microsoft 365 SMTP configurations can now authenticate using OAuth 2.0, providing an additional authentication option for organisations using Microsoft 365.

Firms can configure their Microsoft Entra credentials directly in the Compliance Dashboard to connect their Microsoft 365 email service using modern authentication.

Further Improvements

Version 8.4.0 also includes a refreshed colour theme and branding across the Compliance Dashboard and Address Ownership Portal.

Frankencoin (ZCHF) is also now recognised as an asset within 21 Travel Rule.

Together with version notifications, expanded asset recognition and the other improvements introduced in this release, these updates provide greater flexibility and control across 21 Travel Rule deployments.
