Institutional Vault Release v2.3.0

Operations and wallet API

Operations are modeled with clearer domain objects, subject-based tracking, and a dedicated cancel path so long-running flows can be revoked from the wallet. Related APIs and UI now surface operation types and status more consistently, including user-initiated cancellation where policies allow.

Solana: nonce accounts and cold workflows

The platform indexes Solana create_account flows used for durable nonce setup, and the wallet UI supports adding Solana to cold accounts with nonce accounts, payer selection, and policy-aware confirmation. Fee and nonce handling improvements reduce edge-case failures when creating nonce accounts or adjusting fees interactively.

AWS self-hosted deployment

Load balancer and certificate concerns move into long-lived infrastructure, and more of that stack is importable for repeatable Terraform-based installs. Flat configuration file parsing is supported for AWS on-premises deployments alongside existing patterns.

Access, groups, and governance

Users can belong to multiple groups, with validation aligned between the UI and Policy Nodes for names and identifiers. Administrative authorization for selected custodial wallet provider endpoints is tightened, and staking reporting uses an updated API revision.

Reliability, streaming, and Policy Nodes

Event streaming includes a liveness check; WalletConnect idle-aware health behavior from recent maintenance releases is included. Policy Node software is upgraded (v8.23.2) with logging adjustments so notification delivery issues do not fail underlying operations.
