As we announced a couple of days ago, we continue our progress as the Primary Lending Platform shapes up in the Ethereum Mainnet. Along with our partners at CyberUnit, we have completed the following activities:

Deploying all our smart contracts to the Ethereum Mainnet.

All the smart contracts associated with Fringe Finance’s Primary Lending Platform are now live on the Ethereum blockchain. Etherscan has also verified these contracts to ensure that the code we submitted to the blockchain is identical to the on-chain result. These contracts are:

  • PrimaryIndexToken proxy TransparentUpgradeableProxy 0x46558DA82Be1ae1955DE6d6146F8D2c1FE2f9C5E
  • PrimaryIndexToken masterCopy 0xf45cAaF20787F68787411Ec5D5B9E6920eEd920D

Configuration of collateral assets

In our previous delivery, we advanced the name of six collateral assets to go live along with the platform. However, we have managed to configure one additional asset: Origin’s $OGN.

The initial list of collateral assets to go live along with the Primary Lending Platform is:

Configuration of capital assets

As the Fringe community knows quite well, we’re going live with only one capital asset (i.e., borrowable stablecoin) to streamline the workflow of our Platform in its early days. This asset, USDC, is now configured as a lendable stablecoin on the Primary Lending Platform.


As a part of our deployment, CyberUnit also made a small change to the method transferAdminship() to enable its Admin to be changed to our Gnosis multisig safe. HashEx was requested to re-audit this change, generating a new audit report.

As the last step to finalize the auditing of the Primary Lending Platform and make their audit public, HashEx will review that the contracts on-chain are equal to those submitted for auditing. Expect a statement from them!

What is next for the Primary Lending Platform?

The following activities remain to finalize the deployment of the Primary Lending Platform:

  • Repointing the backend and frontend code that utilizes the Mainnet contracts.
  • Undertaking post-implementation validation tests to verify that the contracts deployed work the same way they did on Tesnet (a standard security measure).
  • Including core UI functions for testing (e.g., deposit collateral, take loan, repay loan, withdraw collateral, deposit capital, withdraw capital).
  • Validating the correct price feeds are in place (another standard security measure).

Development of the Staking and USB Platforms

As we progress with the development of the Primary Lending Platform, we have not slowed down on pushing the Staking and USB Platforms.

The Staking Platform is currently under testing. As a first development, we will deploy Staking only with Single-Asset rewards, which will be followed by Multi-Asset Rewards. Single-Asset rewards will feature:

  • $FRIN staking will allow users to earn fees from the Platform and temporary yield farming opportunities, all paid in $FRIN.
  • Liquidity Providing token staking will allow users to earn $FRIN.
  • $fUSDC (fTokens received by lenders who deposit USDC to be lent out to borrowers) staking will yield users additional incentives on top of their interest-bearing fTokens to incentivize early lenders, lowering interest rates and attracting borrowers.

Through Multi-Asset rewards, the Fringe Finance Platform will allow partner projects to issue rewards to FRIN stakers.

From Marketing

Our Marketing team has been working intensely behind the scenes preparing for the launch of the Primary Lending Platform. Besides the usual participations by themselves and our CTO, Brian “Brain” Pasfield in written media and podcasts, we have engaged our partners behind the scenes and continue to streamline our launch and post-launch activities.

Marketing the Primary Lending Platform constitutes a marathon rather than a sprint race, and we’re confident in our abilities to attract borrowers and lenders alike, even in a depressed market.
