在开始做市之前,你需要完成这些一次性设置步骤——向 Polygon 充值 pUSD、部署钱包、授权代币交易并生成 API 凭证。
1

充值 pUSD

做市商需要在 Polygon 上有 pUSD 来为交易操作提供资金。
方式适用场景文档
Bridge API从其他链自动充值Bridge 充值
直接 Polygon 转账已经在 Polygon 上有 pUSDN/A
跨链桥从 Ethereum 大额充值支持的资产

​
使用 Bridge API

// Get deposit addresses for your Polymarket wallet
const deposit = await fetch("https://bridge.polymarket.com/deposit", {
  method: "POST",
  headers: { "Content-Type": "application/json" },
  body: JSON.stringify({
    address: "YOUR_POLYMARKET_WALLET_ADDRESS",
  }),
});

// Returns deposit addresses for EVM, SVM, and BTC networks
const addresses = await deposit.json();
// Send USDC to the appropriate address for your source chain
2

部署钱包

​
EOA - 外部拥有账户

标准的 Ethereum 钱包。你需要为所有链上交易支付费用(授权、拆分、合并、交易执行)。

​
Safe 钱包 - 推荐

通过 Polymarket 的 relayer 部署的基于 Gnosis Safe 的钱包。优势:
  • 免 gas 交易 — Polymarket 为链上操作支付 gas 费用
  • 合约钱包 — 支持批量交易等高级功能
使用 Relayer Client 部署 Safe 钱包:
import { RelayClient, RelayerTxType } from "@polymarket/builder-relayer-client";

const client = new RelayClient({
  host: "https://relayer-v2.polymarket.com/",
  chain: 137,
  signer,
  relayerApiKey: process.env.RELAYER_API_KEY!,
  relayerApiKeyAddress: process.env.RELAYER_API_KEY_ADDRESS!,
  txType: RelayerTxType.SAFE,
});

// Deploy the Safe wallet
const response = await client.deploy();
const result = await response.wait();
console.log("Safe Address:", result?.proxyAddress);
完整的 Relayer Client 设置(包括本地和远程签名配置)请参阅免 Gas 交易。
3

授权代币

交易前,你必须授权交易所合约使用你的代币。

​
所需授权

代币被授权方用途
pUSDCTF Contract将 pUSD 拆分为结果代币
CTF (结果代币)CTF Exchange交易结果代币
CTF (结果代币)Neg Risk CTF Exchange交易 neg-risk 市场代币

​
合约地址 - Polygon 主网

const ADDRESSES = {
  pUSD: "0xC011a7E12a19f7B1f670d46F03B03f3342E82DFB",
  CTF: "0x4D97DCd97eC945f40cF65F87097ACe5EA0476045",
  CTF_EXCHANGE: "0xE111180000d2663C0091e4f400237545B87B996B",
  NEG_RISK_CTF_EXCHANGE: "0xe2222d279d744050d28e00520010520000310F59",
  NEG_RISK_ADAPTER: "0xd91E80cF2E7be2e162c6513ceD06f1dD0dA35296",
};

​
通过 Relayer Client 授权

import { ethers } from "ethers";
import { Interface } from "ethers/lib/utils";

const erc20Interface = new Interface([
  "function approve(address spender, uint256 amount) returns (bool)",
]);

// Approve pUSD for CTF contract
const approveTx = {
  to: ADDRESSES.pUSD,
  data: erc20Interface.encodeFunctionData("approve", [
    ADDRESSES.CTF,
    ethers.constants.MaxUint256,
  ]),
  value: "0",
};

const response = await client.execute([approveTx], "Approve pUSD for CTF");
await response.wait();
4

生成 API 凭证

要下单和访问需要认证的端点,你需要从钱包派生 L2 API 凭证。
import { ClobClient } from "@polymarket/clob-client-v2";

const client = new ClobClient({ host: "https://clob.polymarket.com", chain: 137, signer });

// Derive API credentials from your wallet
const credentials = await client.createOrDeriveApiKey();
console.log("API Key:", credentials.key);
console.log("Secret:", credentials.secret);
console.log("Passphrase:", credentials.passphrase);
获得凭证后,初始化客户端以进行需要认证的操作:
const tradingClient = new ClobClient({
  host: "https://clob.polymarket.com",
  chain: 137,
  signer: wallet,
  creds: credentials,
});
有关签名类型和 REST API 请求头的完整详情,请参阅身份验证。
