About

WeaveVM Data Retriever (wvm://) is a protocol for retrieving data from WeaveVM network. It leverages the WeaveVM DA layer and Arweave's permanent storage to access and retrieve WeaveVM transaction data through both networks.

Build & Run

git clone https://github.com/weaveVM/wvm-data-retriever.git

cd wvm-data-retriever

cargo shuttle run

wvm:// workflow

Server Methods

Retrieve calldata associated with an WeaveVM TXID

curl -X GET https://gateway.wvm.dev/v1/calldata/$WVM_TXID

Returns the res in the format as in below. Incase the calldata settled on WeaveVM isn't Borsh-Brotli encoded, the Arweave DA verification is omitted as per the current release.

pub struct HandlerGetCalldata {
    pub calldata: String,
    pub arweave_block_hash: String,
    pub wvm_block_hash: String,
    pub war_decoded_calldata: Option<String>, // default to Some("")
    pub wvm_data_da: bool,
    pub ar_data_archive: bool,
    pub da_archive_is_equal_data: bool,
}

Retrieve WeaveVM-Archiver JSON decoded calldata

curl -X GET https://gateway.wvm.dev/v1/war-calldata/$WVM_TXID

Returns

pub struct HandlerGetCalldata {
    pub calldata: String,
    pub arweave_block_hash: String,
    pub wvm_block_hash: String,
    pub war_decoded_calldata: Option<String>, // the decoded JSON representation of `calldata`
    pub wvm_data_da: bool,
    pub ar_data_archive: bool,
    pub da_archive_is_equal_data: bool,
}

Usage as crate

Add wvm-data-retriever to your Cargo.toml

[dependencies]
wvm-data-retriever = { git = "https://github.com/weaveVM/wvm-data-retriever" }

And in your codebase:

use wvm_data_retriever::utils::getters::{get_calldata, get_war_calldata};

Benchmarks

Latency for /calldata

The latency includes the time spent fetching data from WeaveVM RPC and the Arweave gateway, as well as the processing time for Brotli decompression, Borsh deserialization, and data validity verification.
