Copy-trade wallets in Base groupchats.
The problem Alphie solves
Group and social trading today is fragmented and inefficient. Friends and communities trade onchain, but their actions are invisible unless manually shared. This leads to:
- Missed opportunities — Members don’t know when others buy/sell until it’s too late.
- High friction to react — Even when someone shares a trade, copying it requires manual steps across apps and wallets. Conversations usually happens outside the trading app, such as a TG group of friends.
- Low social engagement around trading — Trading is happening in silos instead of being a shared, fun group experience.
Alphie solves this because it lives directly inside Base App, where trading, the social graph, user identities, messaging, and wallets already exist.
Users don’t need to leave the app, compromise wallet security, or rely on external platforms. Trades are tracked from real onchain activity and shared automatically inside group chats, where others can immediately copy, react, or explore details in the miniapp.
How to Play
- Create a group chat on Base App
- Invite @alphie.base.eth to the group chat
- It'll automatically track and send all the trades from the users in the group chat
- Copy trade in 1click or customize the token to sell and the amount
- Tag @alphie.base.eth in the group chat to track also external people using the FID/username. It'll automatically track and send these virtual users.
Challenges we ran into
We approached the project by building something that strongly connects the agent component to the mini-app on the Base App. In doing so, we encountered several challenges:
- The XMTP group chat itself lacks context regarding Farcaster identities. As a result, the only way to gather profile information is through the addresses in the group chat. However, this is not always feasible if the user doesn’t have the Base App wallet address connected to Neynar.
- XMTP inline actions following the XIP 67 (https://community.xmtp.org/t/xip-67-inline-actions/941) don’t allow the developer to fetch whether the user successfully executed a transaction or not through an inline action.
- When using swapToken from the farcaster miniapp SDK, if a user just opens and close the Base App swap modal, it always returns success. You cannot tell whether the user actually completed a swap or not. According to the specs (https://miniapps.farcaster.xyz/docs/sdk/actions/swap-token), it should also return the transaction hashes of the operations performed, 2 in the case of approve + swap.

What is your product’s unique value proposition?
Alphie makes on-chain trading social, transparent, and instantly actionable, right where people already trade and talk. Alphie meets users and traders exactly where they are.
Why it’s uniquely valuable:
- Brings trading into the social layer — Instead of happening in users’ wallets and being shared later (if at all), trades become part of the live group conversation.
- Removes friction between signal and action — When someone trades, others can instantly copy it in one tap — no switching apps, no rebuilding the trade manually.
- Fully onchain and self-custodial — Unlike Telegram bots or web2 social trading platforms, Alphie never asks for keys or control — all actions happen through users’ own Base wallets.
- Built on Farcaster social graph — It uses social identities, messaging, and wallet activity already native to the Base App.
Who is your target customer?
Our initial target users are:
- Crypto-native group chats
- Private friend groups, trading circles, community chats, and Farcaster channels where people already share alpha, call trades, or discuss tokens.
- These users want a seamless way to see each other’s trades without screenshots or manual messaging, and to live-track specific accounts (e.g. Jesse Pollak) even if they’re not part of the group.
- Solo traders and followers on Base
- Individuals who don’t chat much but want to follow specific Base accounts or wallets and copy their trades in real time.
- Alphie gives them automated tracking + 1-click copy trading, without having to join group chats or monitor multiple platforms.
Long-term vision:
To become the default social trading layer on Base - the standard way groups trade together, track each other, and copy trades. Whether you’re in a group chat or trading solo but following others’ wallets, Alphie becomes the interface for social + onchain trading on Base.
Who are your closest competitors and how are you different?
Main competitors include:
- Telegram trading bots (Unibot, Maestro): Enable trade alerts and copy trading, but require risky wallet permissions (not full self-custodial) and live outside Base App.
- Onchain portfolio/social trackers (DeBank, Context): Show wallet activity and rankings but are passive dashboards, not actionable in real time or inside group chats.
- Social trading platforms (Interface, FOMO, Clicker): Mobile-native apps that don’t offer programmable group chats.
How Alphie is different:
Alphie is a trading companion that lives inside Base group chats, where users already trade, talk, and hold their wallets. It’s fully self-custodial, onchain, and turns trades into real-time social and actionable signals with one-tap copy trading with no switching apps, no bots, no trust trade-offs.
What is your distribution strategy and why?
Our go-to-market strategy is community-first and designed specifically for how products grow within the Base ecosystem, bottom-up, socially driven, and credibility-based rather than paid or centralized.
1. Whitelist-driven early access to create exclusivity and high-signal feedback
- We will onboard a curated group of early users, friends, traders, Farcaster power users, Base-native communities, and micro-influencers.
- Access will be granted through a whitelist application, not an open launch, creating organic demand and tighter feedback loops for iterating.
2. Leverage existing social reach (Builders Garden + Farcaster)
- We’ll use Builders Garden’s social accounts, channels, and existing audience to announce the whitelist and share early results.
3. Use Base’s native distribution tools
- QR codes, Zora coins, and other based tools to onboard users.
4. Leverage XMTP-specific distribution
- Alphie is built on XMTP, an open protocol that enables us to run Alphie on any client that supports XMTP standard, such as Convos.
5. Collaborate with Base-native communities
- Partner with active Base communities to enable Alphie in their trading groups.
- Offer custom leaderboards, community tracking, or co-branded group trading challenges to incentivize adoption.
One of the most important growth opportunities will be the public release of the Base App. Our goal is to position Alphie in advance so that when the Base App becomes widely available, users naturally use Alphie to trade with their friends, follow wallets they trust, and also become a social onboarding layer for new Base users.
