Switchboard.xyz Function on Solana Blockchain

Overview

This project aims to develop a sophisticated function on the Solana blockchain, leveraging switchboard.xyz. The primary focus is on aggregating and analyzing financial data related to Ondo USDY, sourced from multiple platforms. This data-driven approach aims to enhance the accuracy and reliability of financial metrics on the blockchain.

Objective

Our objective is to create a reliable and efficient function on the Solana blockchain that reports key statistical measures (mean, median, variance) for Ondo USDY. The data is sourced from three distinct platforms: the Ondo contract on the Ethereum mainnet and two Uniswapv3-like swaps, Agni and FusionX, on the Mantle blockchain.

Challenges Addressed

• Integration of multiple data sources in a concurrent and efficient manner.
• Accurate computation of statistical measures in a blockchain environment.
• Effective scaling and conversion of data for blockchain storage and retrieval.
• Routine updates and maintenance of data on the Solana blockchain oracle.

Key Features

1. Concurrent Data Collection:

   • Simultaneously gather pricing data from the Ondo contract on Ethereum mainnet and the Agni and FusionX swaps on Mantle blockchain.
   • Ensure data integrity and accuracy during collection.

2. Advanced Statistical Analysis:

   • Implement algorithms to calculate mean, median, and variance of USDY prices.
   • Ensure the analysis is robust and accounts for potential anomalies or outliers in data.

3. Blockchain-Compatible Data Conversion:

   • Convert floating-point statistical values into a format compatible with Solana blockchain storage (+e18 values).
   • Maintain precision and accuracy during conversion.

4. Routine Data Updates via Switchboard Function:

   • Utilize the switchboard function to update the Solana program regularly.
   • Ensure seamless and error-free updates to the on-chain oracle.

5. Data Accessibility:

   • Facilitate data consumption and analysis through scripts/watch.ts.
   • Provide clear documentation and examples for using the script.

Technology Stack

• Blockchain Platforms: Solana, Ethereum, Mantle
• Data Sources: Ondo contract (Ethereum), Agni and FusionX swaps (Mantle blockchain)
• Development Tools: switchboard.xyz, Rust programming language

CLI Commands

On devnet, your QUEUE_ADDRESS is CkvizjVnm2zA5Wuwan34NhVT3zFc7vqUyGnA6tuEF5aE

export QUEUE_ADDRESS=CkvizjVnm2zA5Wuwan34NhVT3zFc7vqUyGnA6tuEF5aE

or on mainnet-beta:

export QUEUE_ADDRESS=2ie3JZfKcvsRLsJaP5fSo43gUo1vsurnUAtAgUdUAiDG

to build your docker image and push it to your dockerhub, first modify .env to match your docker username then

make build && make publish

now run the following to get your Enclave Measurement (MrEnclve):

make measurement

export the result:

export MSR={0x...}

and your cluster:

export CLUSTER=devnet

To create the function you can run ts-node scripts/init-basic-oracle.ts or optionall run the below CLI command:

sb solana function create ${QUEUE_ADDRESS?} --container ${DOCKER_IMAGE_NAME} --containerRegistry dockerhub --keypair ~/.config/solana/id.json --cluster ${CLUSTER?} --mrEnclave ${MSR?}

Next, to create a trigger on a regular schedule you can run something akin to - in this case we can omit --params

sb solana routine create $FUNCTION_ID --schedule "*/10 * * * * *" --keypair ~/.config/solana/id.json --network $CLUSTER

And then fund it:

sb solana routine fund $ROUTINE_ID --keypair ~/.config/solana/id.json --network $CLUSTER --fundAmount 0.02

And we can test it in production like so:

sb solana function test

And we can simulate before deploying via:

sb solana function test --devnetSimulate
