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

• 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-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.

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>},

• make check
  • Type check the code, without std feature, exclduing tests.
• make check-tests
  • Type check the code, with std feature, including tests.
• make test
  • Run tests.
