Smithii sdk
Smithii SDK: every token tool in one TypeScript package
Ship token launches, bundlers, multisenders, market making, vesting and cross-chain bridging with one line of code. Our SDK wraps every Smithii tool across Solana, every major EVM chain and SUI.
npm i @smithii/sdk · TypeScript · Node 18+ · Audited by CoinFabrik & Halborn

Why builders pick the Smithii SDK
The same engine that powers Smithii’s live tools, exposed as one TypeScript package. No glue code between Solana, EVM, SUI, Jito and pricing oracles.
Atomic Jito bundles
Every bundler module lands up to 16 wallets in the same block via Jito. No partial fills, no leaked transactions.
Production-tested infra
The same code path that ships millions of transactions for Smithii users.
One install
npm i @smithii/sdk and the full Smithii surface is yours: token creation, bundlers, multisender, market making, vesting and bridging.
Audited & battle-tested


Quickstart: one SDK, every Smithii Tool
Install once, authenticate once, then reach for whatever module you need. Every product follows the same sdk.<module>.<action> shape.
Same SDK. Every Solana launchpad.
One client, every Solana launchpad and DEX. Switch between them by changing a namespace.

Pump.fun

PumpSwap

LetsBonk

LaunchLab

Meteora

Jupiter

Solana
What you can build with the Smithii SDK
Four product shapes our customers ship most often on top of the SDK.
Whitelabel launchpads
Wrap the SDK behind your own brand and offer Pump.fun, LaunchLab, LetsBonk and Moonit launches as features inside a bigger product.
Bots
Listen for new mints on any supported launchpad, decide in code and execute bundled buys that beat public snipers to the block.
Treasury & ops dashboards
Combine token creation, vesting, multisender and holder snapshots into an internal console for your team or your clients.
Cross-chain product flows
Use Mantis bridging to move liquidity between Solana, EVM and SUI inside the same checkout, claim or rebalance flow.
From npm install to first call in 4 steps
- Install the SDK —
npm i @smithii/sdkin any Node 18+ project (works in Next.js API routes, Cloudflare Workers and pure backends). - Get an API key — generate one from your Smithii dashboard. It scopes RPC, Jito tips and rate limits per project.
- Call any module — pick the namespace you need (
sdk.tokenCreator,sdk.multisender,sdk.pumpfun,sdk.mantis, …) and pass it your wallets and params. - Ship it — wire the call to a form, a webhook or a cron and you have a production Smithii-powered feature.
Solana for the launchpad and bundler primitives (Pump.fun, PumpSwap, LaunchLab, LetsBonk, Moonit, Printr), every major EVM chain for token creation, multisender and vesting, and SUI for token creation. Mantis adds bridging across all three.
No. Signing happens inside your process; only signed transactions cross the network. The Smithii SDK has been audited by CoinFabrik and Halborn.
Smithii is legal company incorporated in the United Arab Emirates as Smithii LTD.
We have built a decentralized application (dApp), this means that when you use any tool, you sign transactions directly from your own wallet. We never have access to your tokens, private keys, or wallet funds.
Our smart contracts are audited by independent top firms including Halborn and Coinfabrik and have been used by thousands of projects since our launch in 2022.
Every transaction is verifiable on-chain, but if you find any issue when using our products, our support team is always available to help.
Smithii Tools supports 10+ blockchains including:
Solana, Ethereum, Base, BNB Chain, Polygon, Arbitrum, Avalanche, Blast, SUI, and Eclipse.
Across every bundler module, up to 16 wallets plus the creator land in a single Jito block. Above that, the SDK splits into back-to-back bundles automatically. For multisender airdrops there is no cap — the SDK chunks and retries on its own.
The SDK is server-side first. For browser flows, run the build call from your backend (Next.js route, Worker, edge function) and have the user sign client-side.
No. Every bundler module ships with Jito relays preconfigured. You only pay the tip you choose at call time (we recommend 0.0005–0.005 SOL depending on contention).
One API key covers every module. You pay per successful action (launch, bundle, airdrop, bridge) plus the on-chain fees you would pay anyway. Volume discounts for teams shipping at scale — talk to us.
