Splitdev
Launch a pump.fun coin whose creator fees are split, permanently, between GitHub developers.
Splitdev is a launchpad on pump.fun (Solana). When you launch a coin you pick up to
nine GitHub accounts and their shares. Every trade of the coin pays pump.fun's creator fee, and Splitdev
routes that fee to those developers through pump.fun's own on-chain fee sharing, locked so that nobody,
not even the launcher, can change it later. Developers claim on pump.fun by signing in with GitHub, so
they need no wallet in advance and Splitdev never holds anyone's money.
Live: splitdev.app (Solana mainnet)
Splitdev is an independent project and is not affiliated with pump.fun or GitHub.
Features
- One-prompt launch.
create_v2 plus an optional first buy, the GitHub fee accounts that don't exist
yet, the fee-sharing config with admin revoked, and the launch fee are built client-side and signed
together with signAllTransactions.
- Interrupted launches recover. If the coin lands but the fee split doesn't, the pending launch is
saved per wallet and mint, re-checked against the chain, and offered as "Finish launch".
- Trading on the curve and the pool. Buy and sell on the bonding curve and, after graduation, on
PumpSwap. Quotes include virtual pool reserves, and a trade aborts if the price moved past slippage.
- Permissionless fee distribution. A "Distribute now" button sweeps the creator vault (and the pool
side for graduated coins) to the shareholders.
- Claim lookup.
/claim shows what any GitHub username has waiting and from which coins.
- Spoof-resistant listing. Only coins with Splitdev's exact on-chain shape are listed: final and
active split, treasury first at the allowed share, every other shareholder a pump.fun GitHub fee
account. Trades are read only from events emitted by the pump.fun programs.
- Charts and live data. Candles built from on-chain trade events, rendered with lightweight-charts.
- Hardened server. Per-IP rate limits, a budgeted GitHub API client with caching, image uploads
validated from their bytes, DNS-rebinding-safe metadata fetches, strict security headers.
How it works

W[Launcher wallet] -->|signAllTransactions| L[Launch transactions]
L --> C[pump.fun create_v2 + first buy]
L --> G[GitHub fee accounts<br/>keyed by numeric GitHub id]
L --> F[Fee sharing config<br/>treasury + up to 9 devs, admin revoked]

F --> D[Developers claim on pump.fun<br/>by signing in with GitHub]
There is no Splitdev smart contract: a Splitdev coin is a normal pump.fun coin. Discovery is a single
filtered getProgramAccounts call on pump.fun's fee program (SharingConfig discriminator + treasury at
offset 80), which lists every Splitdev coin without an indexer or database.
Fees (pump.fun mainnet, October 2026): the bonding curve charges 1.25 %, of which 0.30 % is the creator
fee. Splitdev keeps platformBps of the creator fee (10 % today) and charges a 0.01 SOL launch fee; the
rest goes to the GitHub accounts by their shares. Settings live in src/splidev.json
and are validated at build time by next.config.mjs.
Tech stack
- App: Next.js 15 (App Router), React 18, TypeScript, Tailwind CSS, TanStack Query
- Solana:
@solana/web3.js, Solana wallet adapter, @pump-fun/pump-sdk v2, @pump-fun/pump-swap-sdk, SPL Token
- Data: GitHub REST API, Vercel Blob (coin images and metadata), optional Pinata/IPFS
- Testing: Node test runner (unit),
solana-test-validator with pump.fun's real programs dumped from
mainnet (integration), Playwright (browser end-to-end)
- Hosting/CI: Vercel, GitHub Actions

Getting started
Prerequisites: Node.js 22 and npm. The integration tests also need the
Solana CLI (Agave 2.3).
git clone https://github.com/furkan3152/ponsplit.git
cd ponsplit
npm ci
cp .env.example .env.local # public RPCs work out of the box; see the comments in the file
npm run dev # http://localhost:3000
Checks:
npx tsc --noEmit && npm run lint && npm test # typecheck, lint, 39 unit tests
npm run build
Integration tests against pump.fun's real programs on a local validator:
e2e/solana/validator.sh /tmp/ledger
node e2e/solana/build-lib.mjs
RPC=http://127.0.0.1:8899 node e2e/solana/launch-local.mjs # launch, list, trade, distribute, claim lookup
RPC=http://127.0.0.1:8899 node e2e/solana/graduate-local.mjs # graduation and pool trading
RPC=http://127.0.0.1:8899 node e2e/solana/github-fee-compat-local.mjs # current fee vaults, nine recipients
CI (splidev.yml) runs these on every push, plus the web checks and a
Chromium test that launches, trades, distributes and checks every page at desktop and phone widths.
Security
- Non-custodial. Users sign in their own wallet; the site has no signing key and never holds funds.
Fees move only through pump.fun's programs.
- Immutable splits. Fee-sharing admin rights are revoked at launch.
- No secrets in the repo.
.env* and keypair files are gitignored; tests use throwaway keypairs on a
local validator only.
- Trading memecoins is risky; the site shows a risk notice and nothing here is financial advice.
Status
Live on Solana mainnet at splitdev.app. The history also contains SplitEarn, the
earlier Robinhood Chain (EVM) version of the idea.
