Mark a wallet for review with one reaction
Use a familiar Slack signal to turn a wallet mention into a follow-up check. Notis can retrieve its token balances and report the result.
Trigger
Message Reaction Added
Triggered when a reaction is added to a message in Slack. Supports optional filtering by channel and emoji name.
Action
Get Token Balances
This tool retrieves erc20 token balances for a specified ethereum address. it can either return balances for all tokens an address has ever interacted with or for a specific set of token contract addresses. it is useful for checking token balances for wallets, monitoring erc20 token holdings, portfolio tracking, and defi applications.
Why this helps
Wallets flagged for review can remain in chat without anyone taking the next step to inspect their holdings.
- Make a lightweight review signal lead to an actual lookup.
- Reduce repeated reminders to check a wallet later.
- Keep the request linked to the message with the address.
Setup
Build it in a few focused steps.
- 1Connect Slack and Alchemy to Notis once through the portal.
- 2Create an automation with a name that explains the wallet review.
- 3Write one plain-language instruction to look up token balances when the selected reaction marks a message with a wallet address for review.
- 4Select Slack Message Reaction Added and configure the channel or emoji filter if useful.
- 5Choose a report channel and test by reacting to a wallet message.
Questions about this workflow
Does reacting to every message start a balance check?
Use the reaction filter and instruct Notis to proceed only when the message context clearly identifies an address for review.
Can the lookup be limited to specific token contracts?
Alchemy supports a list of token contract addresses. Describe the intended scope in the instruction when the team has a defined set.
