Continuum has a suit of APIs which allow partners to enable their users to perform various wallet related operations and be in total control of their wallet.

We classify the APIs into two divisions based on how partners interact with these APIs.

Two-Step Process APIs

Several wallet operations follow a two-step process for enhanced security:

Prepare (Step 1): Generate an unsigned challenge payload

Submit (Step 2): Submit the signed challenge with signature

This pattern ensures secure, client-side signing of sensitive operations.

Wallet Creation

Create a new non-custodial wallet for an entity using passkey authentication.

Step 1: Prepare Wallet Creation Challenge

Wallet creation API Generates an unsigned wallet creation challenge that must be signed by the user.

Request:

{
  walletName: string;      // Required. Display name for the wallet
  chain?: string;          // Optional. Blockchain chain (default: "SOLANA")
}

Example Response:

{
  "payloadId": "auth_intent_abc123",
  "payloadToSign": "{\"type\":\"ACTIVITY_TYPE_CREATE_WALLET\",\"organizationId\":\"org_xyz\",\"timestampMs\":\"1698765432000\",\"parameters\":{\"walletName\":\"My Primary Wallet\",\"accounts\":[{\"curve\":\"CURVE_ED25519\",\"pathFormat\":\"PATH_FORMAT_BIP32\",\"path\":\"m/44'/501'/0'/0'\",\"addressFormat\":\"ADDRESS_FORMAT_SOLANA\"}]}}",
  "rpId": "localhost"
}

Step 2: Submit Wallet Creation Activity

Submit wallet API, Submits the signed wallet creation activity to complete wallet creation.

Request:

{
payloadId: string; // Required. Payload ID from prepare step
signatureType: string; // Required. Either "WebAuthn" or "ApiKey"
signature: string; // Required. Signed challenge (X-Stamp header value)
}

Example Response:

{
"walletId": "wallet_456",
"addresses": ["5xzG7H8jK9mN1pQ2rS3tU4vW5xY6zA7bC8dE9fG0hI1"]
}

Single-Step APIs

These APIs complete their operation in a single request-response cycle.

Path Parameters:

- entityId (string, required): Entity ID

Request Body:

{
  authType: string; // Required. One of: "API_Key", "OAuth", "Email_Auth", "SMS_Auth"
  authPayload: object; // Required. Configuration specific to auth type
}

Auth Payload Variations:

For API_Key:

{
  apiKeyName: string; // Required. API key name
  curveType: string; // Required. One of: "API_KEY_CURVE_P256", "API_KEY_CURVE_SECP256K1", "API_KEY_CURVE_ED25519"
  publicKey: string; // Required. Public key
  expirationSeconds?: string; // Optional. Expiration time in seconds
}

For OAuth:

{
  providerName: string; // OAuth provider name
  oidcToken: string; // OIDC token
}

For Email_Auth:

{
  email: string; // Email address
}

For SMS_Auth:

{
  phone: string; // Phone number with country code
}

Response:

{
  success: boolean
}

Example Request (API Key Auth):


curl -X POST /api/v1/wallets/entity_123/register-auth \
  -H "Authorization: Bearer -token-" \
  -H "Content-Type: application/json" \
  -d '{
    "authType": "API_Key",
    "authPayload": {
      "apiKeyName": "my-api-key",
      "curveType": "API_KEY_CURVE_SECP256K1",
      "publicKey": "0x04a1b2c3d4e5f6...",
      "expirationSeconds": "31536000"
    }
  }'

Example Request (Email Auth):

curl -X POST /api/v1/wallets/entity_123/register-auth \
  -H "Authorization: Bearer -token-" \
  -H "Content-Type: application/json" \
  -d '{
    "authType": "Email_Auth",
    "authPayload": {
      "email": "user@example.com"
    }
  }'

Example Response:

{
  "success": true
}
