Monitor your DeFi Anchor Protocol "Earn" gains. Only working with UST deposit for now.

Anchor Protocol Monitor

Using anchor.js and terra.js to fetch the total deposit amount of UST in the Anchor Protocol, avoiding the constant check of the web app and get a daily update on your savings.

How it works

You can use the functions inside terra.ts to run the script locally through index.ts or a custom script.
I personnally run the whole process through a Lambda microservice.

Flow

• handler.ts is used to run the function inside AWS.
• A CRON trigger the function each day.
• The functions saves some values in the environnemental variables to reuse next time, thus avoiding the use of a database.
• The function is using Discord Webhooks to alert the user.

How to use

1. Set-up the AWS Lambda func

A. Compress the files and upload the zip to AWS Lambda

• git clone https://github.com/azerpas/anchor-protocol-monitor.git
• npm i && npm run lambda
• Drag and drop dist.zip to a AWS Lambda NodeJS 14.x function
• Define the environnemental variables like the ones inside .env.template
• Change the "Handler" inside the Runtime Settings to handler.handler instead of the default index.handler

B. Use Github actions

• Create a AWS Lambda NodeJS 14.x function
• Define the environnemental variables like the ones inside .env.template
• Fork the repository
• Go into your repository secrets inside settings
• Add these values
  • AWS_ACCESS_KEY_ID: the AWS access key obtained through IAM
  • AWS_SECRET_ACCESS_KEY: the AWS secret key obtained through IAM
  • AWS_REGION: the AWS region of your Lambda func
  • FUNCTION_NAME: the AWS Lambda func name

2. CRON the function

• Use CloudWatch Event to CRON the function
• cron(0 12 * * ? *) to execute the function everyday at 12:00pm
  

TODO

• Add a initial base deposit in Discord
• Return current APY

Need help with loading dist.zip on lambda

Hello,

This project looks amazing!

I have successfully created file "dist.zip" but am unable to run the created function in Lambda.
I got this error :

{
  "errorType": "Runtime.HandlerNotFound",
  "errorMessage": "index.handler is undefined or not exported",
  "trace": [
    "Runtime.HandlerNotFound: index.handler is undefined or not exported",
    "    at Object.module.exports.load (/var/runtime/UserFunction.js:144:11)",
    "    at Object.<anonymous> (/var/runtime/index.js:43:30)",
    "    at Module._compile (internal/modules/cjs/loader.js:1063:30)",
    "    at Object.Module._extensions..js (internal/modules/cjs/loader.js:1092:10)",
    "    at Module.load (internal/modules/cjs/loader.js:928:32)",
    "    at Function.Module._load (internal/modules/cjs/loader.js:769:14)",
    "    at Function.executeUserEntryPoint [as runMain] (internal/modules/run_main.js:72:12)",
    "    at internal/main/run_main_module.js:17:47"
  ]
}

What am i doing wrong ? I uploaded the dist.zip using "Upload zip" in the function, couldn't find any Drag and drop feature..

Thanks for the help.
