Solana’sExecution PlatformRPC & APIs.

Quote, build, submit. Three API calls. No RPC glue.

A public, composable execution API. Below: the full flow in code, and a live quote straight from api.venum.dev. The same API powers Venum Swap in production.

SWAP

The most cost-efficient way to build on Solana.

Flat-rate pricing, composable execution, and a surface designed to remove the most expensive parts of a typical Solana stack before you ever hit a rate limit.

Humans, scripts, or agents. Pick your interface.

The same execution layer exposed through the surface that fits your workflow. Reuse the real products that already ship today.

One execution layer. Two RPC products.

A clean Solana RPC for the server side. A separate URL per app — wallet, mobile app, extension, or dApp — for the client side. Both share the same backend; each ships with the gates that fit how it's actually consumed.

// rpc.venum.dev — JSON-RPC, key-gated, all standard methods
const conn = new Connection('https://rpc.venum.dev', {
  commitment: 'confirmed',
  fetchMiddleware: (url, init, fetch) => {
    init.headers = { ...init.headers, 'X-API-Key': API_KEY }
    return fetch(url, init)
  },
})

const slot = await conn.getSlot()
const info = await conn.getAccountInfo(new PublicKey(mint))

// www-rpc.venum.dev/v1/<your-id> — for dApp frontends
// Origin allowlist + abuse filtering at the edge.
const conn = new Connection(
  'https://www-rpc.venum.dev/v1/abc123',
  'confirmed',
)

const price = await conn.getAccountInfo(poolAddress)

Built to hold other people’s traffic.

The platform assumes your users' safety is on the line. No custody, no secrets shipped to clients, and abuse handled at the edge.

A more cost-efficient execution stack.

Most Solana infra spend comes from polling state, fetching prices, and stitching together plumbing. Venum removes the most expensive patterns first.

Simple, honest, flat-rate.

No swap fees. No hidden costs. No per-call billing surprises. Just a flat monthly line item and the execution surface you need.
