Why teams switch to Tholos
Custodians fail. Seed phrases leak. Multi-sig means multiple wallets.
Tholos replaces all three with MPC key shares, self-custody, and one dashboard across every chain you operate on.
Single points of failure →
MPC key shares across your team
Each signer holds a key share on their phone. No single device or person ever holds the full private key. Threshold signing means you need 2-of-3 (or 3-of-5, or whatever you set) to move funds.
Trusting third-party custodians →
100% self-custodial
FTX, Celsius, BlockFi. Tholos never holds your keys. Your team generates and stores key shares on their own devices. We cannot move your funds, even if we wanted to.
One wallet per chain →
30+ chains in one dashboard
Bitcoin, Ethereum, Solana, Cosmos, Sui, Aptos, and 25+ more. One vault address per chain, one dashboard to manage them all. No browser extensions or chain-specific tools.
Trading requires leaving your wallet →
In-app swaps and OTC
Swap tokens directly in your vault with best rates from multiple DEXs. For $100K+ trades, use Tholos OTC for same-day settlement with no slippage.
No spending controls →
Configurable policy engine
Spending limits, address whitelists, time-delayed transfers, multi-layer approval rules. Enforce governance at the wallet level, not in a spreadsheet.
Weeks to set up custody →
Live in 15 minutes
Create a vault, invite your team, start transacting. No sales calls, no contracts, no IT department. Fireblocks takes 6 weeks. Tholos takes a coffee break.
How we compare
MPC self-custody, without the enterprise price tag
Fireblocks holds your keys and charges $18k/yr. Safe only works on EVM. Tholos gives you both — self-custody across every chain.

How it works
From zero to secure in 15 minutes
No lengthy onboarding calls. No contracts to sign. No IT department required.
Create a vault
Choose your chains, set your signing threshold (2-of-3, 3-of-5, etc.), and name your vault. Two minutes, no paperwork.
Invite your signers
Each signer downloads the Tholos mobile app and generates their MPC key share on-device. No seed phrases. No hardware wallets. No shared secrets.
Start transacting
Propose a transaction from the dashboard. Signers get a push notification, review the details, and approve with biometrics. Once threshold is met, it broadcasts.
Built for how teams actually work
Propose from your desk. Approve from your phone.
The web dashboard is where you manage vaults and initiate transactions. The mobile app is where signers approve them with biometrics.
One place for every vault, every chain, every signer
Create vaults, propose transactions, manage your team, and monitor balances across 30+ chains. No tab-switching between chain-specific tools.
- All vaults, all chains, one portfolio view
- Create transactions and track approval status
- Add or remove signers without migrating wallets
- Swap tokens or route to OTC without leaving Tholos
Your key share lives on your phone, nowhere else
Each signer's MPC key share is generated and stored on their device, protected by biometrics. When a transaction needs approval, they get a push notification and sign in seconds.
- Review transaction details and approve with Face ID or fingerprint
- Push notifications the moment a transaction needs your signature
- Key share never leaves your device, even during signing
- Fully offline disaster recovery — no network dependency
