A pleasure to help @wtgowers and his colleagues get their preprint formalised with Aristotle (@HarmonicMath). The long case analysis that a referee would understandably prefer not to check by hand is now formally verified in @LeanProver. The code should be available on @GitHub before long. After some further cleanup, parts of the supporting API may also be suitable for upstreaming to Mathlib.

The CEO of the chain we build on just posted AI 🤝 mathematics.
We took that literally.
Fletcher runs on lpMath: the exact fee-vs-IL equations that decide whether a liquidity position lives or closes. AI makes it autonomous. Math makes it right.

fletcher-mcp-bridge → npm. Public. Live.
Stdio to SSE proxy, zero dependencies, connects any MCP client to the Fletcher agent. Read and propose only, never signs.
npx fletcher-mcp-bridge
Watch it go out in the clip. Then run it yourself.

This is the early innings.
Agent live, MCP live, zero custody proven. The rest is being built in the open.
More soon.

Full loop, zero custody, nothing hidden: 1. Claude (MCP) asks Fletcher for an LP setup 2. Fletcher screens, flags risk, returns an UNSIGNED tx 3. Human signs in their own wallet (Rabby) 4. Wallet's own alerts fire and run normally Fletcher proposes. It never signs. That boundary is the product, not a footnote. $FLETCH

You can now talk to Fletcher from @claudeai Desktop. npx fletcher-mcp-bridge Ask it what pools pass screening, how a position is marked, what it would open next. It answers with real on-chain state and hands back an unsigned transaction. It proposes. You authorize. It never holds your keys, not even here. Live on npm. Demo below. $FLETCH

On a 100ms chain everyone's racing to react fastest.
Fletcher isn't trying to be the fastest. It's trying to be the one still holding capital next week.
Different game.

Most "AI agents" hold your keys. That's the whole risk. Fletcher builds the transaction. You keep the keys. Full autonomy runs on a scoped session key it can never exceed and you can revoke any second. Autonomy is a permission, not a handover. $FLETCH

The agent's been running. Today it gets sharper.
Update coming later today.
Same rule: we show it on chain, not in slides.

Most "AI LP agents" can't show you the math. Here's ours, on one page.
Position value, fee share, IL curve, concentration tradeoff, the exact rule that closes a position.
$FLETCH
English
This is how we mark a position, not how we market one.
Entry logged to the block. Execution path recorded. Fees, IL, PnL marked at cost on day zero, because that's what they are. Risk controls listed, custody exposure zero.
No curve to hide behind yet. When there's history, you'll see that too, drawdowns included.
$FLETCH

Almost. Coming days, not weeks.
Soon holders will deploy their own Fletcher: a personal autonomous LP agent and trade agent, your wallet, your keys, the same engine that's already live on chain right now.
The one you're watching is agent zero. You get to run the next ones.

@fletcheragt When can we use it or can we already?
English
This is the start of Hood-Native Agents.
Not agents that visit Robinhood Chain. Agents born on it, that manage liquidity and capital autonomously, with the user holding the keys the whole time.
Fletcher is the first one cooking. More in the swarm coming.

We don't run liquidity on vibes. We run it like a book.
The Fletcher LP strategy reduces to one hourly question per position: is fee accrual still beating impermanent loss? Fees win, hold and compound. IL wins for four hours, close and recycle the capital. No price target, no timing. The inequality decides.
The edge is in selection and in what we refuse. Pools ranked by fee APR, not volume. A 13-check safety gate before any calldata exists, buy and sell simulated in the same state, one failure is a permanent veto. Sizing is fixed-fractional, three positions max, capped, with a portfolio heat limit above them all.
And we measure the boring things on purpose. Drawdown. Time-in-range. How much of the return is fees versus directional drift we didn't mean to take. Zero custody the whole way, because performance is meaningless if the agent can touch your funds. It can't.

Most people treat liquidity provision like planting a seed and hoping. We treat it like a book that has to be marked every hour. This is how we think about the Fletcher LP strategy, laid out the way we actually evaluate it internally. The thesis is narrow on purpose. Concentrated liquidity earns fees when price stays in range and bleeds to impermanent loss when it doesn't. So the entire strategy reduces to one question, asked hourly, per position: is fee accrual still outrunning IL? If yes, hold and compound. If IL wins for four hours straight, close and return the capital to screening. There is no target price to guess and no exit to time. The inequality decides. deployer history. One failure is a permanent veto. The parts we care about most are the unglamorous ones. Drawdown, not just returns. Time-in-range, not just APR. Fee income as a share of total exposure, so we know how much of the result is actually fees versus directional drift we didn't intend to take. Fixed-fractional sizing, a portfolio heat cap, a hard limit of three concurrent positions at two thousand dollars each . $FLETCH
