@cfxdevkit/services

Conflux SDK services layer — AES-256-GCM encrypted keystore, Swappi DEX integration, and low-level encryption primitives.


pnpm add @cfxdevkit/services

What’s included

Export	Description
`KeystoreService`	File-backed HD wallet keystore encrypted with AES-256-GCM + PBKDF2
`SwapService`	Swappi DEX router — getPrice, swap, getTokenInfo, pool listing
`EncryptionService`	Low-level AES-256-GCM encrypt/decrypt primitives

Encrypted keystore


import { KeystoreService } from '@cfxdevkit/services'
 
const keystore = new KeystoreService('./my-wallet.json')
 
// Create new wallet
const { mnemonic, address } = await keystore.create('my-strong-password')
 
// Unlock existing
const wallet = await keystore.unlock('my-strong-password')
console.log('eSpace address:', wallet.evmAddress)

Swappi DEX integration


import { SwapService } from '@cfxdevkit/services'
import { ClientManager } from '@cfxdevkit/core'
 
const client = new ClientManager({ network: 'mainnet' })
const swap = new SwapService(client)
 
// Get price quote
const quote = await swap.getPrice({
  tokenIn: '0xCFX_TOKEN_ADDRESS',
  tokenOut: '0xUSDT_ADDRESS',
  amountIn: parseEther('10'),
})
 
// Execute swap
const hash = await swap.swap({
  tokenIn: '0xCFX_TOKEN_ADDRESS',
  tokenOut: '0xUSDT_ADDRESS',
  amountIn: parseEther('10'),
  slippageTolerance: 0.5, // 0.5%
  walletClient,
})

Encryption primitives


import { EncryptionService } from '@cfxdevkit/services'
 
const enc = new EncryptionService()
const { ciphertext, iv, salt } = await enc.encrypt('secret data', 'password')
const plaintext = await enc.decrypt(ciphertext, iv, salt, 'password')
