A little over a year after we launched cowpy, we’re excited to see it has powered more than $100M in settled volume.

Built for @CoWSwap interactions, cowpy gives Python builders native tools for MEV-protected trading, order-book management, smart-contract execution, subgraph queries, and multi-chain support.

So far:

• $124M in volume
• 27K PyPI downloads
• 53K orders across 6 chains

Get started with:

pip install cowdao-cowpy

Moooo 🐮

Stop loss order: "Sell it if the price drops."

You can't watch every move, delegate it for the Air Rescue crew 🪂

[CoW Swap @CoWSwap]

Market order: “Now, please.”
Limit order: “Not a penny more.”
TWAP order: “Let’s take it slow.” 🐄

Market impact, without the jargon, explained in one easy article. 👇 https://t.co/g79p6uBvYp

We’re thrilled to build Portfolio Manager alongside @1inch.

Aqua lets liquidity providers put capital across multiple strategies. Keeping that inventory balanced is the hard part.

Portfolio Manager holds your target exposure as price and flow move - no liquidity migration every time the book shifts.

Built on Aqua. More soon.

DAOs still run critical ops completely in the open.

Hiding token balances isn’t enough. The real challenge is executing business logic on confidential state without moving execution off-chain.

We’re using @zama’s FHEVM to build a suite of confidential DAO products. Fully homomorphic encryption allows smart contracts to process private inputs directly on-chain, shielding treasury operations without sacrificing verifiability.

If DAOs are going to manage real balance sheets, privacy needs to be native to their architecture. Stay tuned!

cowpy is the Python SDK for @CoWSwap interactions.

It gives builders native tools for MEV protected trading, order book management, smart contract execution, subgraph queries, and multi-chain support.

Usage across the last six months:

• $18M in volume
• 27K PyPI downloads
• 8.8K orders across 6 chains

Get started with:

pip install cowdao-cowpy

One of CoW's best features is now available to everyone 🐮

TWAP order discovery on @CoWSwap is powered by the Programmatic Orders API we built and open-sourced to handle programmatic order flows and conditional execution.

Great to see core infrastructure we shipped running in production.

[CoW Swap @CoWSwap]

For years, one of DeFi's best-kept secrets sat behind a locked door. 🔒

TWAP orders.

Advanced traders swore by them. Everyone else needed a Safe, a custom fallback handler, and an afternoon to spare.

Today, the door comes off its hinges. TWAP is open to every wallet.

Did you know you can run the entire @CoWSwap stack locally offline?

Until now, testing autopilot or driver changes meant relying on remote testnets, live RPCs, or mocked assumptions.

The CoW Playground Offline Development Mode packages the full environment:

• Local Anvil node with deterministic CREATE2 contract deployments
• Pre-seeded Uniswap V2 liquidity, test tokens, and periphery contracts
• Local CoW Swap UI wired directly to Anvil for end-to-end testing

One-command startup. Zero external RPC dependencies. Real settlement execution on local state.

Querying EVM history has always been painful.

@typedarray and the @ponder_sh team proposed a real fix at the protocol level with five new JSON-RPC query methods:

• eth_queryBlocks
• eth_queryLogs
• eth_queryTraces
• eth_queryTransfers
• eth_queryTransactions

Instead of dumping raw blocks and stitching state client-side, the spec adds server-side filtering, field projection, and relation joins in a single call.

We rely heavily on Ponder across our infrastructure. They’ve consistently pushed EVM indexing forward, and moving these primitives directly into the RPC standard fixes the problem where it actually belongs.

Hope to see other EVM chains look closely into this.

Seeing @fomo users getting sandwiched on L2s brings back memories.

One of the first things we built for @CoWSwap was the "Have I Been MEV'd?" bot.

We built @mevscanner so users could measure how much they lost to MEV bots instead of wondering where their slippage went.

Unfortunately, some things in crypto never change: route through batch auctions or keep paying the searcher taxes.

[bleu @bleubuilders]

@zama Thank you for the support guys! 💪 We're keen to keep building on Zama and bring some cool privacy-first products to the market.

🥉 We scored 3rd place in the @zama developer program with our dark pool!

Started with buybacks, now designing production infrastructure for confidential DAO ops: payments, vesting, and treasury execution on FHEVM.

[bleu @bleubuilders]

DeFi buybacks leak everything: budget, schedule, every fill, all public. TradFi fixed this in the 80s with dark pools.

We spent the last few days on our first FHE project, a dark pool for protocol buybacks, built on @zama FHEVM. 🧵

@CoWSwap We wrapped the latest milestone (core contracts and subsolver routing) and are heading into audits.

Full forum update:

https://t.co/FPDr7OLdag

Want to run as a subsolver once live? Send us a DM.

[bleu @bleubuilders]

Becoming a full @CoWSwap solver comes with legal, capital, and infra hurdles only well-resourced teams can clear today.

CoW BYOS changes that.

We're building a meta-solver so teams can plug routing strategies straight into batch auctions without the overhead.
