General Contracts

Tokenomics Contracts

Tokenomics related smart contracts are hosted on ../contracts/tokenomics.

Building Contracts

You will need Rust 1.64.0+ with wasm32-unknown-unknown target installed.

You can compile each contract:

Go to contract directory and run

cargo wasm
cp ../../target/wasm32-unknown-unknown/release/astroport_token.wasm .
ls -l astroport_token.wasm
sha256sum astroport_token.wasm

You can run tests for all contracts

Run the following from the repository root

cargo test

For a production-ready (compressed) build:

Run the following from the repository root

./scripts/build_release.sh

The optimized contracts are generated in the artifacts/ directory.

Deployment

You can find versions and commits for actually deployed contracts here.

Docs

Docs can be generated using cargo doc --no-deps

Bug Bounty

The contracts in this repo are included in a bug bounty program.

lib.rs:

Circular buffer which is built over Item and [Map]. Might be useful to store time series data in contracts.

Example

use cosmwasm_std::testing::MockStorage;
use astroport_circular_buffer::{BufferManager, CircularBuffer};

const CIRCULAR_BUFFER: CircularBuffer<u128> = CircularBuffer::new("buffer_state", "buffer");

let mut store = MockStorage::new();
BufferManager::init(&mut store, CIRCULAR_BUFFER, 10).unwrap();
let mut buffer = BufferManager::new(&store, CIRCULAR_BUFFER).unwrap();

let data = (1..=10u128).collect::<Vec<_>>();
buffer.push_many(&data);
buffer.commit(&mut store).unwrap();

let values = buffer.read(&store, 0u32..=9, true).unwrap();
let all_values = buffer.read_all(&store).unwrap();
