what it does

every swap is validated through zero-knowledge proofs. the chain sees that a valid trade happened. it does not see who, how much, or through which route. mev bots cannot frontrun what they cannot read.

import { MevSwap } from 'mevswap'

const swap = new MevSwap({ agentId: 'my-agent' })

const result = await swap.swap({
  from: 'SOL',
  to: 'USDC',
  amount: 10,
  privacy: 'zk',
  rules: {
    maxSlippage: 1,
    requireApproval: false,
  }
})
// swapped privately in 280ms. no sandwich. no trace.

install

npm install mevswap

why

| | | |---|---| | mev protection | zk-routed orders are invisible to sandwich and frontrun bots | | zk privacy | wallet identity, amount, and route never hit the public mempool | | agent native | built for autonomous ai agents via mcp integration | | spending rules | maxSlippage, requireApproval, token whitelist, maxAmountUsd | | jupiter routing | best price across every solana dex, settled privately | | mcp server | native tool for claude, gpt, cursor |

usage

basic swap

import { MevSwap } from 'mevswap'

const client = new MevSwap()

const result = await client.swap({
  from: 'SOL',
  to: 'USDC',
  amount: 5,
  privacy: 'zk',
})

console.log(result.txHash)
console.log(result.amountOut)

with approval gate

const client = new MevSwap({
  agentId: 'trading-agent-01',
  onApprovalRequired: async (req) => {
    console.log(`agent wants to swap ${req.amount} ${req.from} to ${req.to}`)
    return true
  }
})

const result = await client.swap({
  from: 'SOL',
  to: 'BONK',
  amount: 1,
  rules: {
    requireApproval: true,
    maxSlippage: 2,
    allowedTokens: ['USDC', 'BONK', 'JUP'],
  }
})

mcp integration

import { MevSwapMCP } from 'mevswap'

const server = new MevSwapMCP({ agentId: process.env.AGENT_ID })
const tools = server.tools()
const result = await server.call('swap', { from: 'SOL', to: 'USDC', amount: 5 })

spending rules

rules: {
  requireApproval: true,
  maxSlippage: 1,
  maxAmountUsd: 500,
  allowedTokens: ['USDC', 'SOL', 'JUP'],
}

agents are not free to do whatever. you set the rails. they swap inside them.
