SDK 代币兑换

通过 AI 驱动的 0x 路由构建并执行代币兑换。

提示模式

模式	示例
基于数量	"Swap 0.1 ETH to USDC"
基于价值	"Buy $100 worth of DEGEN"
百分比	"Swap 50% of my ETH to USDC"
全部卖出	"Sell all my DEGEN"
特定链	"Swap ETH to USDC on Polygon"

# 数量兑换
"Swap 0.1 ETH to USDC"
"Exchange 100 USDC for WETH"
"Swap 1000 DEGEN to ETH"

# 价值兑换
"Buy $100 worth of DEGEN"
"Purchase $50 of ETH"

# 百分比兑换
"Swap 50% of my ETH to USDC"
"Sell 25% of my DEGEN"

# 特定链兑换
"Swap 0.1 ETH to USDC on Base"
"Exchange 100 USDC for WETH on Ethereum"

ERC20 授权处理

对于 ERC20 兑换（卖出 ETH 以外的代币），在兑换前需要授权。

const result = await client.promptAndWait({
  prompt: "Swap 100 USDC to WETH",
});

const swapTx = result.transactions?.find(tx => tx.type === "swap");

// 检查是否需要授权
if (swapTx?.metadata.approvalRequired) {
  // 首先执行预构建的授权交易
  await wallet.sendTransaction(swapTx.metadata.approvalTx);
}

// 然后执行兑换
await wallet.sendTransaction(swapTx.metadata.transaction);

SDK Token Swaps

Build and execute token swaps with AI-powered 0x routing.

Prompt Patterns

Pattern	Example
Amount-based	"Swap 0.1 ETH to USDC"
Value-based	"Buy $100 worth of DEGEN"
Percentage	"Swap 50% of my ETH to USDC"
Sell all	"Sell all my DEGEN"
Chain-specific	"Swap ETH to USDC on Polygon"

# Amount Swaps
"Swap 0.1 ETH to USDC"
"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";

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) {
  const tx = result.transactions[0].metadata.transaction;
  await wallet.sendTransaction(tx);
}
