Transaction Lifecycle

Every transaction follows a secure, auditable path from creation to confirmation.

Create

Operator or API initiates a withdrawal or transfer request with destination and amount.

2

Approval

Required approvers sign off according to quorum rules (N-of-M).

3

MPC Signing

Verifies each request against your governance policy before co-signing. No complete key ever exists.

4

Broadcast & Confirm

Signed transaction is broadcast to the network and confirmed on-chain.

Your cosigner runs on YOUR infrastructure. No complete private key ever exists in a single location.

Frequently Asked Questions

Self-custody means you retain full control over your private keys. With Carabaas, your MPC cosigner runs on your own infrastructure. No transaction can be signed without your key share participating, and Carabaas cannot access or move your funds unilaterally.

The private key is never created or stored in full. Instead, two key shares are generated — one held by your cosigner and one by the Carabaas platform. To sign a transaction, both parties must participate in a cryptographic protocol. Neither party alone can produce a valid signature.

You always have an escrowed seed backup that allows you to recover full access to your funds independently. This ensures business continuity regardless of the Carabaas platform status.

Carabaas supports 60+ blockchain networks including Bitcoin, Ethereum, Solana, Polygon, and many more. ERC-20, SPL, and native tokens on supported networks are detected and available automatically.

Sandbox access is typically granted within 24 hours. The full onboarding to production — including cosigner deployment, key ceremony, and policy configuration — can be completed in 1-2 weeks depending on your requirements.

Carabaas is an ICT infrastructure provider, not a custodian or regulated financial entity. The platform is designed to help your business meet its own compliance obligations under MiCA, DORA, EBA outsourcing guidelines, and GDPR. The self-custody model is designed to help you maintain full control and responsibility over assets.
