🛠 SDK Integration Examples
EVM Networks Setup
import brdzSDK from '@anantla/brdz-sdk';
// Configure SDK for EVM operations
const config = await brdzSDK.config;
config.setBaseUrl('https://api.brdz.link/api');
config.setApiKey('your_api_key_here');
// Get USDC balance on Sepolia
const crosschain = await brdzSDK.crosschain;
const balance = await crosschain.getUSDCBalance('sepolia', '0xYourAddress');
// Cross-chain transfer from Sepolia to Amoy
const transfer = await crosschain.initiateTransfer({
user_id: 123,
amount: "100.00",
from_chain: "sepolia",
to_chain: "amoy",
token: "USDC",
recipient_address: "0xRecipientAddress",
return_address: "0xYourAddress"
});
Cardano Operations
// Get Cardano USDC balance
const cardano = await brdzSDK.cardano;
const balance = await cardano.getUsdcBalance('addr_test1...');
// Cardano onramp (fiat to USDC)
const onramp = await cardano.onramp({
user_id: 123,
amount: 100.00,
currency: "USD",
bank_reference: "BANK123"
});
XRPL Operations
// Get XRPL issuers
const xrpl = await brdzSDK.xrpl;
const issuers = await xrpl.getAllIssuers();
// Create USDC trustline
const trustline = await xrpl.createTrustline({
user_id: 123,
currency: "USD",
issuer_address: "r9wxh8hwJcaQnC4ypWqZqpoYY4MS9Shmos"
});
🚀 MCP (AI Commerce) Support
MCP Consumer contracts enable AI-powered commerce on supported networks:
Available MCP Networks
| Network | MCP Contract | AI Commerce | Status |
|---|---|---|---|
| Neon EVM | 0x7D14B8910c90199e9D513213647E223040569739 | ✅ Full Support | ✅ Active |
| Polygon Amoy | 0x119Fce364bdaDe5B4B43a259a3F65E1a4676a4A2 | ✅ Full Support | ✅ Active |
| Sepolia | N/A | ❌ Not Available | 🚧 Planned |
MCP Usage Example
// AI-powered purchase with chain selection
const mcp = await brdzSDK.mcp;
// V2 Flow with chain selection
const chainSelector = await mcp.chainSelector({
product: productData,
pricing: pricingData,
recipient: recipientData
});
// Create order on selected chain
const order = await mcp.createOrderV2({
product: productData,
pricing: pricingData,
recipient: recipientData,
selected_chain: "amoy", // or "neon"
wallet_address: "0xYourWallet"
});
⚠️ Important Notes
Network Status
- All networks are production-ready but currently in testnet/devnet phase
- Mainnet migration planned for future releases
- Test tokens only - no real value
Security Considerations
- Never expose private keys in client-side code
- Use environment variables for sensitive configuration
- All contracts are audited for testnet use
- Bridge operations are monitored 24/7
Rate Limits
- EVM RPC calls: Standard provider limits apply
- XRPL operations: 100 requests per minute
- Cardano operations: Blockfrost API limits apply
- Cross-chain transfers: 10 per hour per user
