The Open Runtime Module Library (ORML) is a community maintained collection of Substrate runtime modules.

Runtime Modules Overview

orml-traits
- Shared traits including BasicCurrency, MultiCurrency, Auction and more.
orml-utilities
- Various utilities including OrderSet.
orml-tokens
- Fungible tokens module that implements MultiCurrency trait.
orml-currencies
- Provide MultiCurrency implementation using pallet-balances and orml-tokens module.
orml-oracle
- Oracle module that makes off-chain data available on-chain.
orml-prices
- Provide basic asset price abstraction.
orml-auction
- Auction module that implements Auction trait.
orml-vesting
- Provides scheduled balance locking mechanism, in a graded vesting way.
orml-gradually-update
- Provides way to adjust numeric parameter gradually over a period of time.
orml-schedule-update
- Provides way to schedule a call to be dispatched at later block.

To add an ORML module to your runtime, simply include the following to your runtime's Cargo.toml file. For instance, to add orml-tokens module:

[dependencies]
# --snip--
orml-tokens = { git = "https://github.com/laminar-protocol/open-runtime-module-library.git", default-features = false }

and update your runtime's std feature to include this module:

std = [
    # --snip--
    'orml-tokens/std',
]

You should implement it's trait like so:

/// Used for orml_tokens
impl orml_tokens::Trait for Runtime {
	type Event = Event;
	// --snip--
}

and include it in your construct_runtime! macro:

Tokens: orml_tokens::{Module, Storage, Call, Event<T>, Config<T>},
