Tiered storage
The hot wallet holds a day's withdrawals, a warm tier buffers demand, and the cold tier never touches a network.
ON-CHAIN TOOLS
Cold Wallet Solution
Cold Storage & Treasury Management
Cold/hot separation for platforms and project treasuries. The hot wallet holds only operating float, the bulk sits fully offline, and multisig thresholds, address allowlists and automatic sweeping close off the path from "key leaked" to "funds gone".

What You Get
Offline signing
Transactions are built online and signed offline, ferried by QR code or USB — the key never sees the internet.
Multisig approval
Gnosis Safe or in-house threshold signing — large withdrawals need M-of-N approval to move.
Hardware wallets
Ledger, Trezor and Keystone support, with multi-device and role management for teams.
Sweep & payout
Deposit addresses sweep into the warm wallet automatically; payouts go out in signed batches.
Monitoring
Balance anomalies, non-allowlisted destinations and oversized withdrawals alert instantly and can freeze the channel.
How It Works
Assess
Map asset size, withdrawal frequency and where the current process is weakest.
Design tiers
Set the three-tier limits, signing thresholds and approver roles.
Build & drill
Deploy, then run deposits, sweeps and withdrawals end to end with test funds.
Handover & drill
Hand over the system and rehearse key-loss and device-failure scenarios.

FAQ
QDo you ever touch our keys?
Never. Key generation and backup happen entirely on your devices — we deliver the system and the process, nothing else.
QWhat if a device is lost?
The multisig threshold plus sharded seed backup means a single loss does not touch the funds — you re-sign following the playbook.
QDoes it integrate?
It ships with an API and webhooks that plug into your existing deposit/withdrawal flow without a rewrite.
QWhich chains?
BTC, EVM chains, TRON and Solana out of the box; other chains can be adapted.
