Two products, one platform
Custody your treasury.
Power your product.
MPC Wallet
Full control of digital assets across chains. Private key shares are held by your organization — CryptoMelon has zero access to your funds.
- Threshold MPC key generation & signing
- Multi-chain: BTC, ETH, BNB, SOL, TRX + tokens
- Sub-address hierarchies with nicknames & tags
- Withdrawal allowlists, quorum policies, audit trail
Wallet API
One standardized API to mint addresses, sign transactions and consolidate funds. You own the addresses. We own the plumbing.
- REST + Webhooks with signing secrets
- Programmatic sub-address creation
- Auto-sweep with dedicated gas accounts
- Scoped API keys, IP allowlists, HMAC replay guard
Native & stablecoin coverage
One control plane. Every chain your treasury needs.
USDT and USDC across all EVM & non-EVM networks. Native gas accounts fund every sweep automatically.
Security by construction
No single party. No single point of failure.
Every key is split across independent MPC shares. Signing requires threshold approval from your operators and hardware-bound devices — never a single seed sitting on a server.
Wallet-as-a-Service
Ship crypto features without owning the wallet stack.
Mint addresses per user, per merchant, per invoice. Consolidate to your treasury with a single sweep call. Gas is metered from dedicated accounts you control — no hand-crafted UTXO handling, no chain-specific RPC glue.
