# Coming soon

The vault handles the full lifecycle of keys, policies, signing, and audit. Here is what is coming next.

## Multi-user approvals

The Signing Policy and Administrative Policy will support human approval quorums: you specify how many approvers from a named group must sign off, and the request waits until that threshold is met before it proceeds.

This will include a richer approvals inbox in the web app, with decoded transaction intent displayed for each pending request so approvers can make informed decisions without inspecting raw bytes.

## On-chain keys

The vault will generate and import wallet keys for blockchain use: Ed25519 for Solana and similar chains, and ECDSA (secp256k1) for Ethereum and EVM-compatible chains, as well as BLS for validator staking. Wallet derivation (BIP-32/BIP-44) will produce addresses directly in the vault.

This brings the same zero-exposure key management, Signing Policy governance, and audit trail to on-chain operations.

## DEX coverage

With on-chain keys in place, the vault will support signing transactions for decentralized exchanges. You will be able to use the same keys, the same Signing Policy, and the same audit trail whether you are operating on a CEX or a DEX.

## More venue coverage

The policy engine already decodes signing payloads for the top exchanges. Coverage is expanding to include additional centralized exchanges, new custody provider integrations, and OTC desk authentication flows. Each added venue brings structured signing context (asset, amount, destination address) that you can use as conditions in your Signing Policy.

## High-frequency signing

For latency-sensitive trading strategies, a co-located signer will be available as an optional component. It runs inside an AWS Nitro Enclave alongside your trading machine, holds the key reconstructed in memory only, and targets sub-millisecond signing latency. Rust and Java SDKs are planned.

## Address book and cross-venue limits

Signing Policy conditions will expand to include:

* **Address book:** a whitelist of approved destination addresses. Rules such as "deny withdrawals to any address not in the address book" become a single click.
* **Cross-venue USD limits:** aggregate withdrawal limits across all venues, so a $50K daily limit applies to the total across Binance, Coinbase, OKX, and any other configured venue, not to each one separately.

## Mobile approvals

Approval requests will be deliverable to a mobile app with push notifications. Approvers can review decoded transaction intent and sign with a passkey on their phone, without needing to open a laptop.
