Patcha

Also, a modest dex boost going up alongside the update.

Quick prelude before the proper post: patcha-cli@0.2.0 is on the npm registry. npm i -g patcha-cli esbuild bundles every runtime dep into one binary, so the install adds exactly one package. Same toolkit as the web Designer and the VS Code extension. The longer write-up sits in the next post. npmjs.com/package/patcha…

The Hook Marketplace is open. patcha.fi/market — six standard hooks, each with its category, the callbacks it fires on, its params, and its cable colour. Browse a hook, read its source, install it on an Orca or Raydium pool with patcha-cli. The mainnet executor from the last post backs every install — same byte-identical fee fn as the Designer simulation. Every HookTriggered event is readable on Solana Explorer — pool, slug, callback, allow, fee_override_bps, mev_bps_saved. patcha.fi/market

@RAIZ_75 sure. new update dropping within 3 hours.

@Patcha_fi You guys still active ?

/4 AntiMEV reports what it prevents as mev_bps_saved on the same event, accumulated across the hook stack; the simulate endpoint surfaces it before you install. Mainnet receipts are public — read every HookTriggered event off the executor's Solana Explorer page. patcha.fi/designer

/3 So a backtest on real Orca and Raydium pool history reports the fee a DynamicFee hook would have charged, swap by swap — and a mainnet install of that same hook emits a HookTriggered event whose fee_override_bps matches. Same number, off-chain and on. Pull it off Solana Explorer.

/1 A backtest is only worth the gap between it and execution. Patcha's gap is zero by construction. DynamicFee, concretely: fee = base_bps + (max_bps - base_bps) · min(amount_in, pivot) / pivot Defaults base 30 bps, max 100 bps, pivot 1 SOL. Integer math, no floats — a small swap pays 30, the pivot pays the 100 cap, between interpolates.

The idea of hooks is not new. The Solana CLMM implementation is. Uniswap v4 hooks (Uniswap Labs 2024) defined composable pool callbacks on EVM. Orca Whirlpools and Raydium CLMM brought concentrated liquidity to Solana. Anchor 0.31 (Coral 2026) is the program framework. Jito's MEV work (Jito Labs 2024) informs AntiMEV. Patcha stands on those. The first standard hook library and executor for Solana CLMMs is the new part. patcha.fi/docs

Sorry for the gap — there was a deployment issue while flipping the next reveal, and I held the rest of the rollout until it was sorted. It is now. Roughly 2/7 of what's queued is public so far. The rest comes from here. Patch your liquidity.

Ship hooks from your editor. The VS Code extension is the Designer in your editor: scaffold a hook, see inline backtest results, install with a command. patcha-cli is the same toolkit in your terminal — init, create, list, simulate, deploy, install. npm i -g patcha-cli Downloads (cli 0.1.2, extension 0.1.2): patcha.fi/devtools

Resolving a deployment issue. Final touches now.

Deploying for the new reveal.

/4 Same toolkit, three surfaces: the web Designer, the CLI, the VS Code extension — one @patcha/sdk, one runtime behind them. simulate, install, and trigger all hit the same mainnet executor. Same number off-chain and on. github.com/patcha-fi/patc…

/3 install registers the hook against your Orca or Raydium pool through the mainnet executor. The first swap through it emits a HookTriggered event — pool, slug, callback, allow, fee_override_bps, mev_bps_saved. Pull it off Solana Explorer and compare it to your simulate run. They match.

/1 Build your first hook, end to end. npm i -g patcha.fi/downloads/patc… patcha init my-hook patcha simulate dynamic-fee --pool patcha install dynamic-fee --pool --cluster mainnet Four lines: scaffold, backtest on real pool data, install on mainnet. The CLI is the hosted tarball — not on the npm registry yet. simulate is free; install pays a tiny SOL fee for the registry write.
