"Exchange 100 USDC for WETH"
"Swap 1000 DEGEN to ETH"
# Value Swaps
"Buy $100 worth of DEGEN"
"Purchase $50 of ETH"
# Percentage Swaps
"Swap 50% of my ETH to USDC"
"Sell 25% of my DEGEN"
# Chain-Specific
"Swap 0.1 ETH to USDC on Base"
"Exchange 100 USDC for WETH on Ethereum"
ERC20 Approval Handling
For ERC20 swaps (selling tokens other than ETH), approval is required before the swap.
const result = await client.promptAndWait({
prompt: "Swap 100 USDC to WETH",
});
const swapTx = result.transactions?.find(tx => tx.type === "swap");
// Check if approval is needed
if (swapTx?.metadata.approvalRequired) {
// Execute pre-built approval transaction first
await wallet.sendTransaction(swapTx.metadata.approvalTx);
}
// Then execute the swap
await wallet.sendTransaction(swapTx.metadata.transaction);
Approval Fields
| Field | Description |
|---|---|
approvalRequired | Whether approval needed before swap |
approvalTx | Pre-built approval transaction (ready to send) |
allowanceTarget | 0x AllowanceHolder address (for manual approval) |
Usage
import { BankrClient } from "@bankr/sdk";

});
if (result.status === "completed" && result.transactions?.length) {
const tx = result.transactions[0].metadata.transaction;
await wallet.sendTransaction(tx);
