What is the two-wallet system in the Bankr SDK?

It separates the Payment Wallet (required for $0.01 USDC API micropayments) from the Context Wallet (receives tokens/NFTs). This enhances security by keeping trading funds in a separate address.

What are the requirements for the payment wallet?

The payment wallet must have a small USDC balance on the Base chain to cover x402 micropayments (typically $0.01 per API request).

Can I use different wallets for different transaction requests?

Yes, you can provide a specific walletAddress in the prompt options to override the default receiving address for that specific request only.

How do I securely provide my private key to the SDK?

Private keys should always be stored in environment variables (e.g., BANKR_PRIVATE_KEY) and never hardcoded. Use a .env file and ensure it is included in your .gitignore.

What is the purpose of the getWalletAddress() method?

It returns the address currently configured for context; if no override is provided, it returns the address derived from the payment wallet's private key.

Configures and manages BankrClient wallet setups for secure x402 micropayments and multi-chain DeFi interactions.

소개

The SDK Wallet Operations skill streamlines the initialization and management of the BankrClient, the primary interface for Bankr's multi-chain DeFi infrastructure. It specializes in implementing the SDK's unique two-wallet system, which separates the payment wallet used for x402 micropayments from the context/receiving wallet for enhanced security. This skill provides precise guidance on environment variable configuration, private key validation, and address derivation, ensuring developers can build secure, production-grade Web3 applications with minimal friction.
