Parrot Program 的 SDK
根据 process.env.CHANNEL 获取对应的 parrot program 配置
获取 channel 对应配置文件的绝对路径
// process.env.CHANNEL = 'dev'
const configPath = getParrotConfigPath() // /<path_to_config_folder>/config.dev.json
获取 channel 对应配置文件的内容
// process.env.CHANNEL = 'dev'
const config = getParrotConfig() // { ... } config object
获取 channel 对应的某个 debt type
// process.env.CHANNEL = 'dev'
const config = getDebtTypeConfig() // { ... } debt type object or raise debt type not found error
获取 channel 对应的某个 vault type
// process.env.CHANNEL = 'dev'
const config = getVaultTypeConfig() // { ... } vault type object or raise vault type not found error
生成在与 Parrot 交互时需要用到的 instructions 的模块
输入参数类型定义:
{
provider: Provider,
args: T, // 输入参数类型定义的泛型
overrideConfig?: ParrotConfig
}
返回参数类型定义:
{
instructions: web3.TransactionInstruction[];
cleanupInstructions: web3.TransactionInstruction[];
signers: web3.Account[];
extra: T; // 额外返回的数据定义
}
初始化 vault account data
args: ({ vaultType: web3.PublicKey; owner: web3.PublicKey; })
extra: ({ vaultPublicKey: web3.PublicKey })
向 vault 中存入 collateral token
args: ({
vaultType: web3.PublicKey;
vault: web3.PublicKey;
collateralFrom: web3.PublicKey;
collateralFromAuthority: web3.PublicKey;
collateralAmount: BN;
})
extra: void
从 vault 中取出 collateral token
args: ({
vaultType: web3.PublicKey;
vault: web3.PublicKey;
vaultOwner: web3.PublicKey;
receiver: web3.PublicKey;
unstakeAmount: BN;
})
extra: void
从 vault 中借出 debt token
args: ({
vaultType: web3.PublicKey;
vault: web3.PublicKey;
vaultOwner: web3.PublicKey;
receiver: web3.PublicKey;
debtAmount: BN;
})
extra: void
降 debt token 归还到 vault
args: ({
vaultType: web3.PublicKey;
vault: web3.PublicKey;
debtFrom: web3.PublicKey;
debtFromAuthority: web3.PublicKey;
repayAmount: BN;
})
extra: void
尝试清算指定的 vault
args: ({
vaultType: web3.PublicKey;
vault: web3.PublicKey;
debtFrom: web3.PublicKey;
debtFromAuthority: web3.PublicKey;
liquidatedCollateralReceiver: web3.PublicKey;
liquidateAmount: BN;
})
extra: void
通过 provider 和 process.env.CHANNEL 生成对应 channel 的 parrot sdk 对象
(provider: Anchor.Provider) -> ParrotProgram
通过参数计算 collateral ratio
(
debtAmount: string,
collateralAmount: string,
debtTokenDecimals: number,
collateralTokenDecimals?: number,
collateralTokenPrice?: string
) -> string
通过参数计算指定 slot 之后预计的 debt
(
vaultTypeInterestAccum,
interestAccum: string,
debtAmount: string,
currentSlot: number,
targetSlot: number
) -> string
根据参数计算清算价格
(
debtAmount: string,
collateralAmount: string,
liquidationRatio: string
debtTokenDecimals: number,
collateralTokenDecimals: number,
) -> string
