What is Cobo?
Cobo is a digital asset custody and wallet infrastructure company operating since 2017. One API covers custodial, MPC, smart contract and exchange wallets across 80+ chains and 3,000+ tokens. It states SOC 2 Type II certification and licenses in Hong Kong and the United States. Wallet-as-a-Service starts at $299 per month.
How Cobo works
Cobo's Wallet-as-a-Service 2.0 API puts four wallet types behind one API and SDK set: Custodial, MPC, Smart Contract and Exchange Wallets.
Custodial wallets rely on hardware isolation with HSMs and Intel SGX. MPC wallets split signing across distributed TSS nodes running in Trusted Execution Environments. In an Organization-Controlled MPC vault, key share holders (Main Key, Signing Key and Recovery Key) each hold shares on their own TSS nodes. For Main and Signing keys, one share is generated and stored encrypted in Cobo's multi-cloud infrastructure on your behalf.
Each vault has two root extended public keys, one on the secp256k1 curve for chains like Bitcoin and Ethereum and one on EdDSA for chains like Solana and TON, from which wallet addresses are derived. Token transfers route either off-chain through the Cobo Loop network between Cobo Portal accounts, or on-chain. The force_internal and force_external parameters let you pick the route. Exchange Wallets connect to venues including Binance, OKX, Bybit and Deribit.
How to start with Cobo
- There is no self-serve sign-up.
- Cobo Portal supports sign-in only, and Cobo Sales provisions your account and organization after you book a demo.
- Developers start in the development environment (api.dev.cobo.com), which supports testnets.
- The production environment (api.cobo.com) requires an active paid plan, and API keys registered in one environment do not work in the other.
- To send a first request, generate an Ed25519 key pair, for example with OpenSSL, register the public key in Cobo Portal under Developer, API Keys, and assign a role and wallet scope.
- SDKs cover Python (3.7 or newer), JavaScript, Go, Java and PHP.
- MPC wallets additionally require setting up a vault in the Portal first.
Cobo fees and limits
- Starter costs $299 a month and includes 2 users, 6,000 wallet addresses, $300,000 in outgoing transfer volume and 15,000 API calls.
- Standard costs $999 a month with 5 users, 12,500 addresses, $1.25 million in outgoing volume and 65,000 API calls.
- Overages run $0.15 per extra address, 0.20% (Starter) or 0.16% (Standard) of extra outgoing volume, $0.04 or $0.03 per extra API call, and $100 per extra user.
Enterprise is priced by quote and adds 24/7 dedicated support and automated token sweeping.
Risks to know before using Cobo
- On Custodial wallets Cobo holds the keys, and on Organization-Controlled MPC wallets Cobo holds one key share for the Main and Signing key groups, so you depend on Cobo's infrastructure and continued service.
- Cobo states zero breaches since 2017, SOC 2 Type II certification, ISO 27001 compliance and licenses in Hong Kong and the United States.
- It also notes that product availability and client eligibility vary by jurisdiction.
