Geb Admin

This class extends the core GEB class with additional tools and contracts that are not used as often as other SAFE management tools. Here you will find utils for contracts such as DSPause, ESM etc. These contracts are scattered across several repositories. Please refer to the smart contract documentation to learn more about them.

IMPORTANT: To avoid bloating the main geb.js package this class is only available in a separate package. Please install it like this:

npm install @reflexer-finance/geb-admin

And after that you are ready to use the admin tools similar to the GEB class:

import { ethers } from 'ethers'
import { GebAdmin } from "@reflexer-finance/geb-admin"

 const provider = new ethers.providers.JsonRpcProvider('http://kovan.infura.io/<API KEY>')
 const gebAdmin = new GebAdmin('kovan', provider)

Constructors

+ new GebAdmin(network: GebDeployment, provider: GebProviderInterface | Provider): GebAdmin

Defined in packages/geb-admin/src/geb-admin.ts:52

Parameters:

Name

Type

Description

network

GebDeployment

Either 'kovan', 'mainnet' or an actual list of contract addresses.

provider

GebProviderInterface | Provider

Either a Ethers.js provider or a GEB provider. Support for Web3.js will soon be added.

Returns: GebAdmin

Properties

contracts

• contracts: ContractApis

Inherited from GebAdmin.contracts

Defined in packages/geb/lib/geb.d.ts:70

Object containing all GEB core smart-contracts instances for direct level interactions. All of the following contracts object are one-to-one typed API to the underlying smart-contract. Read-only functions that do not change the blockchain state return a promise of the return data. State modifying function will return synchronously a pre-filled transaction request object:

{
  to: "0x123abc.."
  data: "0xabab234ab..."
}

This object follow the TransactionRequest model of ethers.js (Also similar to the model used by web.js). The object can be completed with properties such as from, gasPrice, gas (gas limit, web3.js ony) or gasLimit (gas limit, ethers.js only). The object can then be passed to the sendTransaction of ehters.js or web3.js

Example:

 // Setup geb.js an ethers
 const provider = new ethers.providers.JsonRpcProvider('http://kovan.infura.io/<API KEY>')
 const wallet = new ethers.Wallet('<Private key>', provider)
 const geb = new Geb('kovan', provider)

 // Contract read function: Fetch the debt ceiling
 const debtCeiling = await geb.contracts.safeEngine.globalDebtCeiling()

 // State changing function: Manualy liquidate a SAFE
 const tx = geb.contracts.liquidationEngine.liquidateSAFE(ETH_A, '0x1234abc...')
 await wallet.sendTransaction(tx) // Send the Ethereum transaction

Currently the following contracts ae available in this property:

SAFEEngine
AccountingEngine
TaxCollector
LiquidationEngine
OracleRelayer
GlobalSettlement
DebtAuctionHouse
PreSettlementSurplusAuctionHouse
PostSettlementSurplusAuctionHouse
SettlementSurplusAuctioneer
GebSafeManager
GetSafes
BasicCollateralJoin
CoinJoin
Coin (System coin ERC20 contract)
GebProxyRegistry
FixedDiscountCollateralAuctionHouse
Weth (ERC20)

For detailed information about the functions of each contract we recommend referring directly to the smart-contract code and documentation

Returns an instance of a specific geb contract given a Geb contract API class at a specified address

import { contracts } from "geb.js"
const safeEngine = geb.getGebContract(contracts.SafeEngine, "0xabcd123..")
const globalDebt = safeEngine.globalDebt()

Type parameters:

getProxyAction

Defined in packages/geb/lib/geb.d.ts:84

Given an address returns a GebProxyActions object to execute bundled operations. Important: This requires the address to have deployed a GEB proxy through the proxy registry contract. It will throw a DOES_NOT_OWN_HAVE_PROXY error if the address specified does not have a proxy. Use the deployProxy function to get a new proxy.

Parameters:
