Wallet-as-a-Service API references, MPC custody concepts, webhook integration guides, and security best practices for institutional crypto operations.

MPC Wallets

Learn how threshold signing, key generation, and proactive resharing protect your assets without a single seed phrase.

Wallet API

Create sub-addresses, query balances, initiate sweeps, and manage gas accounts through a standardized REST API.

Webhooks

Receive signed deposit and transfer events. Verify HMAC signatures, configure retry policies, and inspect delivery logs.

Security

Understand our SOC 2 Type II controls, hardware-bound key shares, policy engine, and operational safeguards.

Quick start: create a wallet

Authenticate with a scoped API key, then create a sub-address for your customer or invoice.

curl https://api.cryptomelon.io/v1/wallets \
  -H "Authorization: Bearer cm_live_9f2a…" \
  -H "Content-Type: application/json" \
  -d '{
    "chain": "ETH",
    "nickname": "Customer-8842",
    "tag": "deposit"
  }'

The response returns a sub-address, chain details, and the gas account assigned for sweeps.
