Configuration

Configure RPC endpoints, API keys, and understand how wallet credentials are handled.

WalletConfig

The SDK supports four chains. Each chain is configured with a private key and an optional custom RPC endpoint inside the wallets object.

wallet-config.ts

import { createSkills } from "dex-skills";

const skills = createSkills({
  wallets: {
    solana: {
      privateKey: process.env.SOLANA_PRIVATE_KEY,
      rpcUrl: process.env.SOLANA_RPC_URL, // default: public mainnet
    },
    base: {
      privateKey: process.env.BASE_PRIVATE_KEY,
      rpcUrl: process.env.BASE_RPC_URL, // default: public Base RPC
    },
    bnb: {
      privateKey: process.env.BNB_PRIVATE_KEY,
      rpcUrl: process.env.BNB_RPC_URL, // default: public BSC RPC
    },
    tron: {
      privateKey: process.env.TRON_PRIVATE_KEY,
      fullHost: process.env.TRON_FULL_HOST, // default: https://api.trongrid.io
      apiKey: process.env.TRON_API_KEY,
    },
  },
});

Environment Variables

Parameter	Type	Description
SOLANA_RPC_URL	string	Solana RPC endpoint URL. Default: `Public mainnet`
BASE_RPC_URL	string	Base chain RPC endpoint URL. Default: `Public Base RPC`
BNB_RPC_URL	string	BNB Smart Chain RPC endpoint URL. Default: `Public BSC RPC`
TRON_FULL_HOST	string	TRON full node API host. Default: `https://api.trongrid.io`
TRON_API_KEY	string	API key for TronGrid access. Required for production TRON usage.
BITQUERY_API_KEY	string	Bitquery API key for cross-chain token data queries.

.env

SOLANA_RPC_URL=https://api.mainnet-beta.solana.com
BASE_RPC_URL=https://mainnet.base.org
BNB_RPC_URL=https://bsc-dataseed.binance.org
TRON_FULL_HOST=https://api.trongrid.io
TRON_API_KEY=your-trongrid-api-key

Platform-to-Chain Mapping

Each platform identifier maps to a specific chain. The SDK automatically routes requests to the correct chain configuration.

Platform ID	Platform	Chain	Native Currency
pumpfun	Pump.fun	Solana	SOL
letsbonk	LetsBonk	Solana	SOL
moonshot	Moonshot	Solana	SOL
zora	Zora	Base	ETH
clanker	Clanker	Base	ETH
fourmeme	Four.meme	BNB	BNB
sunpump	SunPump	TRON	TRX

Security

Private key handling

Private keys are provided in the wallets configuration and used only for transaction signing. They are never transmitted beyond the RPC call. Store them in environment variables and never commit them to version control.

Environment variables

Never commit .env files to version control. Add .env to your .gitignore and use a secrets manager in production.
