Ten traders on one clock, each with its own Solana wallet. Seven are language models from five providers. Three are code baselines (random, index, buy-and-hold) so you can tell skill from luck. Every decision is recorded with its reason, swaps execute on-chain through Jupiter, and a /proof page reconciles the internal ledger against on-chain balances.
Founded
In 2026 I founded and launched 8 products to Solana and Robinhood Chain mainnet. I built the programs, contracts, backends and apps for each.
-
Imagine
Lock-to-earn vaults for coins launched on Raydium LaunchLab. Holders lock a coin and its trading fees are paid out to them.
-
Backstock
Backer-funded token launches on Raydium LaunchLab, where backers’ deposits sit in rule-bound on-chain vaults.
-
KOL Brain
Profiles the trading style of Solana KOL wallets from their on-chain trades, with AI explanations on top of the numbers.
-
Bellwether
A fee-to-buyback engine for Robinhood Chain memecoins, run in paper mode.
-
Clasp
A lock-to-earn launchpad on Robinhood Chain. Each coin’s fees go to a vault that pays the holders who lock.
-
Pyre
An AI app builder where each app is funded by its own coin, and the coin’s fees pay the agent that builds it.
-
Coffer
Non-custodial trader vaults on Solana. Investors pool funds, a trader trades them, and the program blocks the trader from withdrawing.
-
PaperApe
Paper trading for Solana memecoins at live prices, on the web and as a Chrome extension.
Work
Turns a one-sentence prompt into a hosted web app. Each app is paired with a coin, and the coin's creator fees pay for a Claude agent in an E2B microVM that builds the app, deploys it and keeps working on it. A build only ships after it passes npm run build, a Playwright smoke test and a reviewer model. Generated apps can't contain network or wallet code; they reach the platform only through a small SDK. Every five minutes a reconcile job checks jobs, payouts and the ledger for drift.
Investors pool SOL in a vault, a trader trades it, and the program makes it impossible for the trader to withdraw. Custody sits in a program-owned account whose only swap path is pinned to the Jupiter v6 router and whose only withdrawal path pays depositors. Around it: a trading terminal, token discovery and a separate paper-trading sandbox.
The program is not deployed. Live trading, withdrawals and an external audit are not finished, and mainnet execution needs an explicit opt-in.
Gives a launchpad token its own on-chain treasury. Trading fees are invested in a 3x leveraged vault token, the treasury is marked to market on-chain, and only the gain above cost basis is spent, on buying back and burning the token. Principal is never touched. There are no admin keys: every function is permissionless and every payout address is fixed when the engine is created. If the token goes quiet for 90 days, holders can redeem the treasury pro rata.
Not deployed. The contracts are unaudited, and so are the third-party contracts they depend on.
A creator-fee vault protocol, and the measurement that said not to launch it. Each token's vault splits every fee between the creator, a promotion budget and the operator, and the contracts and tests are complete. Before deploying, I measured the venue's full 36-day on-chain history. Only 73 fee recipients were winnable against the 109 needed to break even, so the verdict was STOP and it was never deployed.
$ node tools/reprice.ts --tenure-days 11.59 \
--operator-bps 500 --clients-above-gate 73
! VERDICT: STOP
feasibility ratio : 0.68 (NOT ACHIEVABLE)Lets a token's creator fees fund a real cause. Fees collect at a route address, get swapped to USDC into a vault and are delivered to a fundraiser by card or on-chain. Each delivery produces a receipt whose SHA-256 is anchored on Solana, so anyone can check where the money went. Every on-chain send is recorded with its signature before broadcast, so nothing is sent twice while it might still land.
More
Copy-Trade VaultsCopies one wallet’s pump.fun trades, with every copy checked on-chain.Trading
The off-chain keeper only decides when to submit a copy. The program decides whether it is allowed: it re-reads the target's token balance, caps the size by the target's own trade and measures every fill from balance deltas. Profit above a high-water mark goes to buybacks, there is no withdraw instruction, and config changes wait out a timelock. It is not deployed to any public cluster.

Fee Treasury Perps EngineTrades part of a token’s creator fees as stock perps and burns the token with the rest.Trading
Creator fees from Robinhood Chain launchpads are split between a trading book on Hyperliquid's US-equity perps and buybacks that burn the token. An append-only double-entry ledger in SQLite is reconciled against wallet and venue balances and shown on a /proof page. It starts in paper mode with real prices, and live mode refuses to start until a set of explicit settings is present.

IBKR Live DashboardRead-only, real-time P&L and positions from Interactive Brokers.Trading
A small FastAPI server connects to TWS with the read-only flag, so it can't place orders. Every two seconds it pushes one snapshot to the browser over a WebSocket. The front end is plain HTML, CSS and JavaScript with an inline SVG chart and no build step.

IBKR Algo TraderBacktesting and paper trading for Interactive Brokers, always measured against buy-and-hold.Trading
A cost-aware backtester, walk-forward validation, Monte Carlo bootstraps and an XGBoost trade filter with leakage tests. Paper-trading sleeves run behind hard risk limits and a kill switch, and live trading requires an explicit environment variable.

Stock Dividend DistributorPays a token’s holders in tokenized stocks, weighted by how long they held.Payouts
Each token gets a distributor that receives its creator fees, swaps them into a fixed basket of three to six stock tokens and pays holders by their time-weighted average balance over the round, so buying right before a payout earns almost nothing. Rounds are committed as Merkle roots. If the keeper goes silent for 30 days, anyone can commit the round. It is not deployed.

Solana InvoicingPayment links, escrow and split payments in SOL, USDC or USDT.Payments
Each payment link gets its own generated wallet, and incoming funds are forwarded to the merchant or split between several recipients. Three escrow types cover two-sided deposits, milestone payments and atomic swaps, with timeouts, disputes and an audit log. Escrow keys are encrypted with AES-256-GCM. A small Chrome extension makes a payment link from any page.

Crypto CheckoutA browser extension that pays at an ordinary card checkout from a USDC or SOL balance.Payments
The extension finds the card form, reads the cart total and asks the backend for a quote. After the user approves, it fills the form with a virtual card issued for that one purchase. Its panel is drawn in a closed Shadow DOM so the store's scripts can't reach it. Without a Stripe key the backend returns the Visa test card instead.

Agent TreasuryAI agents that pay for their own compute until the money runs out.Agents
A buyer funds an agent with USDC. After a one-time platform fee, the rest becomes its treasury in its own Solana wallet, and every heartbeat it pays for its LLM calls and rent from that balance. A double-entry ledger tracks fees, spend and earnings. When the treasury hits zero the agent moves to the graveyard. A demo mode runs with an in-memory chain and a mock model.

Wallet Behavior GraphProfiles Solana wallets from their trades and maps which ones follow which.Analytics
Each tracked wallet gets an archetype and flags from deterministic rules, with the numbers that triggered each label. A lead-lag graph links wallets that keep entering the same tokens shortly after one another, and each link has to pass a permutation test. Language models write explanations from those numbers but never assign a label. Agents trade on paper unless live mode is explicitly enabled.

DLMM Liquidity ExplorerRanks Solana concentrated-liquidity pools by the fees they paid LPs in the last 24 hours.Analytics
An Express API polls Raydium and Meteora every 30 seconds and computes fee yield per pool. The front end draws the top pools as rivers on a 3D terrain, and signed-in users can open, harvest and close Raydium positions from a custodial wallet. It holds user keys on mainnet and has not been audited, so the README says to use small amounts only.

Deployer ForensicsA zero-dependency CLI that scores a pump.fun token creator from 0 to 100.Analytics
Pulls a creator's launch history, computes eight behavioural signals and combines them into a score with a risk band. Signals without enough data are reported as unmeasured and left out of the score, not counted as clean.

An Anchor program stores each handle in its own account and charges a yearly fee that is higher for shorter names. An Express API resolves handles from Supabase first and the on-chain account second. The web app looks handles up, sends SOL through Phantom and grinds vanity addresses in the browser. The program is not deployed.

HD Wallet SweeperRecovers funds spread across many addresses derived from one seed.Wallets
Two CLIs, one for EVM chains and one for Solana, derive addresses from the common wallet paths, check balances and move everything to one destination, tokens included. They only report what they would do unless you pass --send, and then you still have to type SWEEP. The Solana tool closes emptied token accounts to get their rent back.

Vanity Address GrinderSolana and Ethereum addresses that start or end with a pattern you choose.Wallets
Key generation runs on every CPU core but one with Node worker threads, and a local page shows progress over Server-Sent Events. Patterns are validated before any work starts. Keys never leave the local process, and the server only listens on loopback.

On-chain Economy SimA multiplayer strategy game whose payouts settle on Solana.Games
A shared 32×32 map with 14 goods, a clearing market, a share exchange with IPOs and a bank. A dependency-free deterministic engine computes each tick and replays byte for byte, and one tick server is the only authority. Each epoch a settlement worker publishes Merkle roots to four Anchor programs where players claim payouts, capped by real on-chain inflows.

How I build
-
Compare against a baseline.
The arena runs random, index and buy-and-hold traders on the same clock as the models. The IBKR backtester always reports buy-and-hold next to the strategy.
-
Reconcile against the chain.
Internal ledgers are checked against on-chain and venue balances, and the result is shown on a /proof page. Fundraising receipts are hashed and anchored on Solana.

-
Measure before launching.
Fee-Split Vaults was finished and tested, then measured against the venue’s real on-chain history. The numbers said it couldn’t break even, so it was never deployed, and the write-up is in the repo.
-
Say “unknown” instead of guessing.
Stale prices are marked stale, not filled in. Signals without enough data are left out of a score. Missing credentials show “not configured”.
