Complete guide to operations supported by the Bankr SDK. The SDK accepts natural language prompts and returns transaction data for execution.
Builds Bankr SDK transactions for ERC20/ETH/NFT transfers, ETH/WETH conversions, cross-chain bridges, NFT minting/buying, approvals, and DeFi operations.
Provides reusable TypeScript client code, JobStatus types, transaction interfaces for swaps, approvals, ERC20/NFT transfers, and common files like package.json/tsconfig for Bankr API integrations.
Builds natural-language crypto/DeFi agents that turn prompts into wallet-signed, fork-simulated transactions across Ethereum, Base, Arbitrum, Optimism, Polygon, and Linea. Integrates 40+ apps including Uniswap, Aave, and Lido.

import { BankrClient } from "@bankr/sdk";
const client = new BankrClient({
privateKey: process.env.BANKR_PRIVATE_KEY as `0x${string}`,
});
const result = await client.promptAndWait({
prompt: "Swap 0.1 ETH to USDC on Base",
});
if (result.status === "completed" && result.transactions?.length) {
// Execute the returned transaction with your wallet
await wallet.sendTransaction(result.transactions[0].metadata.transaction);
}
Each request costs $0.01 USDC via x402 micropayments. Gas fees for transactions are paid separately.
