$ npm install @projectsophon/constantsThis package contains useful constants for use when interacting with the Dark Forest smart contracts within JavaScript or TypeScript.
You can install this package using npm or
yarn by running:
npm install --save @projectsophon/constants
yarn add @projectsophon/constants
When using this in a plugin, you might want to load it with skypack
import * as constants from 'http://cdn.skypack.dev/@projectsophon/constants'
• Const BLOCK_EXPLORER_URL: "https://dashboard.tenderly.co/tx/xdai"
The URL to the block explorer for the chain being used. Prepended to transaction links, etc
• Const CONTRACT_PRECISION: 1000
The precision of Energy & Silver stored in the Dark Forest smart contracts.
Energy and Silver are not stored as floats in the smart contracts,
so any of those values coming from the contracts need to be divided by CONTRACT_PRECISION
and any values being sent to the contract need to be multiplied by CONTRACT_PRECISION.
• Const DEFAULT_GAS_PRICES: GasPrices
In case we cannot load gas prices from xDai, these are the default auto gas prices.
• Const DEFAULT_MAX_CALL_RETRIES: 12
By default, the various ContractCaller will retry a blockchain read this many times.
• Const EMPTY_ADDRESS: EthAddress
The 0x0 Ethereum address, which is used for unowned planets, artifacts without an owner, etc.
• Const EMPTY_ARTIFACT_ID: ArtifactId
A blank ArtifactID (all zeros).
• Const EMPTY_LOCATION_ID: LocationId
A blank LocationID (all zeros).
• Const GAS_PRICES_INTERVAL_MS: 60000
The amount of time between gas price refreshes when fetching prices from the oracle.
• Const GAS_PRICE_API: "https://blockscout.com/xdai/mainnet/api/v1/gas-price-oracle"
The URL for xDai's API that returns the gas prices for 35th, 60th, and 90th percentiles of gas prices in the previous 200 blocks. Useful for auto gas price setting.

• Const HAT_SIZES: string[]
• Const LOCATION_ID_UB: bigint
The upper-bounds of a LocationID.
Represents the maximum possible value that the MiMC hash function (used for IDing locations in the universe) can output.
A LocationID must be less than LOCATION_ID_UB / PLANET_RARITY in order to be considered a valid planet.
• Const MAX_ARTIFACT_RARITY: ArtifactRarity = ArtifactRarity.Mythic
The value of the maximum, valid artifact rarity
• Const MAX_ARTIFACT_TYPE: ArtifactType = ArtifactType.ShipTitan
The value of the maximum, valid artifact type
• Const MAX_AUTO_GAS_PRICE_GWEI: 15
In case xDai's auto-price is something ridiculous, we don't want our players to insta run out of money.
• Const MAX_BIOME: Biome = Biome.CORRUPTED
The value of the maximum, valid biome
• Const MAX_PLANET_LEVEL: PlanetLevel = PlanetLevel.NINE
The value of the maximum, valid planet level
• Const MAX_SPACESHIP_TYPE: ArtifactType = ArtifactType.ShipTitan
The value of the maximum, valid spaceship type
• Const MIN_ARTIFACT_RARITY: ArtifactRarity = ArtifactRarity.Common
The value of the minimum, valid artifact rarity
• Const MIN_ARTIFACT_TYPE: ArtifactType = ArtifactType.Monolith
The value of the minimum, valid artifact type
• Const MIN_BIOME: Biome = Biome.OCEAN
The value of the minimum, valid biome
• Const MIN_PLANET_LEVEL: PlanetLevel = PlanetLevel.ZERO
The value of the minimum, valid planet level
• Const MIN_SPACESHIP_TYPE: ArtifactType = ArtifactType.ShipMothership
The value of the minimum, valid spaceship type
• Const PLANET_CLAIM_MIN_LEVEL: 3
The minimum level required for claiming a planet.
• Const RECOMMENDED_MODAL_WIDTH: "400px"
PlanetContextPane is this wide, and all the subpanes of that modal also try to stay this size as well.
• Const SpecialKey: Object
Keys to handle in a special fashion when dealing with key presses
| Name | Type |
|---|---|
Control | "Control" |
Escape | "Escape" |
Shift | "Shift" |
Space | " " |
Tab | "Tab" |
