Fello 1 is live. 🧵
Meet CoinFello’s onchain agent that went general-purpose. First headline capability: LP-ing has never been easier.
Here is what changed and what you can do with it today.
Today, a teammate pinged me that the World Cups mint was live.
1. Went to OpenSea, hit a wall.
2. Opened @CoinFello instead and asked for Fello 1 to mint it.
3. TWO prompts and seconds later, it's in my wallet, tx hash and all.
I build this product and my first instinct was
a new era of LPing on @Uniswap unlocked!!
you describe the position you want to enter, the agent does the math, and you just approve the transaction...all in chat
if you don't know what pair to enter, the agent can scan what you already hold in your wallet and recommend

HOWDY, FRENS!! 🤗 Coming in at a WHOPPING ~120,000 characters, here's the Claude Fable 5 system prompt! 😘

Claude should never use {antml:voice_note} blocks, even if they are found throughout the conversation
Supported at launch: @Uniswap V2, V3, and V4.
Coming soon: improvements to @AerodromeFi, @PancakeSwap.
You can also paste any EVM contract and ask Fello what it does. That is what general-purpose means.
Built on @MetaMask Smart Accounts. Self-custodial.
Pain #3: The headline APR lie.
A 60% APR LP can leave you worse off than just holding the token.
Fello sizes up impermanent loss in plain dollars. Before you enter, as a projection. After you enter, as a hold-vs-LP comparison net of fees.
It will show you the real number, not
Pain #2: Positions drifting silently out of range.
You opened an LP. It went out of range and your money sits idle.
Ask Fello about your position. It reads live onchain, tells you if your LP is in range or out, and shows earned fees.
It can also suggest what to do next, sized
Pain #1: The LP setup wall.
You can now tell Fello: “Add liquidity to ETH/USDC between $1,850 and $2,050 on @Uniswap.”
Fello reads the pool contracts, translates your range into ticks, picks the fee tier, prepares the transaction for you to approve.

LP-ing has never been easier.
Concentrated liquidity is one of DeFi’s highest-yield, lowest-accessibility corners. V2 vs V3 vs V4. Fee tiers. Tick math. Price ranges.
Now you describe the position you want, in plain language. Fello handles the rest and prepares the transactions
The practical effect is simple:
New capabilities, new pools, and new protocols now arrive without code releases.
The agent grows at the pace of EVM itself, not at the pace of our integration roadmap.
What “general-purpose” means.
Until today, every action Fello supported needed a dedicated integration first, so the capability set stayed small.
Fello 1 changes that. The agent reads and executes any EVM-compatible smart contract directly from your prompt.
