Cartesi enables developers to create an entirely new wave of DApps not previously possible on Ethereum or Layer 2s. It also allows developers to focus on what they’re building instead of where they’re building, or what inconvenient limitations they may otherwise need to contend with.
Why developers are building with Cartesi:
- DApps are deployed on their own customizable application-specific rollup chains;
- DApps don’t compete with each other in Cartesi’s ecosystem for scarce blockspace;
- Cartesi provides Ethereum or L2’s with orders of magnitude more computational capacity;
- Developers can code decentralized logic with their favorite libraries, compilers and other time-tested open source components;
- DApps preserve the strong security guarantees and censorship resistance of the underlying blockchain;
- Cartesi Rollups opens up the design space for more expressive and computationally intensive blockchain applications;
- Cartesi Rollups can be deployed as a Layer 2 (on top of Ethereum), as a Layer 3 (on top of Optimism, Arbitrum, zkEVM chains, etc.), or as sovereign rollups;
- Reusing existing tooling, having full programmability is a great way to innovate faster without reinventing the wheel!

Starter Tutorial
Earn RDNT Tokens By Lending and Borrowing Stablecoins with Radiant Capital on Arbitrum

In just over 6 months, Radiant Capital has grown to become one of Arbitrum’s top DeFi applications by TVL and borrowing volume.
Radiant is developing a first-of-its-kind omnichain money market, meaning users will eventually be able to deposit on any major chain and borrow supported assets across multiple chains.
Imagine depositing ETH as collateral on Arbitrum but then borrowing USDC through Radiant onto Polygon or Ethereum Mainnet.
With Radiant, you have a familiar lending and borrowing DeFi application where lenders supply liquidity in the form of DAI, USDC, USDT, ETH, and WBTC vs borrowers who can withdraw the assets against their collateralized funds and pay interest. If borrowers don’t maintain a healthy LTV (loan-to-value) ratio, they get liquidated.
Like the original Compound COMP program, both lenders and borrowers earn rewards in the form of RDNT tokens, but different from COMP, these rewards vest over 28 days unless users choose to exit early and face a 50% penalty fee.
For those who lock/stake their RDNT, they get to share in 50% of “protocol fees” including the RDNT that a user might forgo in order to exit vesting RDNT early.
What’s more unique is Radiant’s cross-chain interoperability built on Layer Zero.
Currently, Radiant supports lending and borrowing on Arbitrum for USDC, USDT, DAI, WBTC, ETH while also supporting borrowing USDC or USDT to other chains such as Ethereum L1, Polygon, Avalanche, and Fantom. In the future, lenders reclaiming their collateral will be able to direct which chain to withdraw the funds to and what percentage they’d like sent to each chain.
Today, I’ll show how I can earn RDNT while lending and borrowing stablecoins.
I chose to specifically demonstrate collateralizing (lending) DAI and borrowing DAI, which I can redeposit as collateral to borrow more, allowing me to earn a net ~7-8% APR every time I collateralize/lend and borrow DAI at up to 75% LTV, avoiding the 85% Liquidation Threshold.

Before we get started, please be aware of these risks.
- Smart contract risk in Radiant
- Front-end spoof attack on the Radiant dApp
- Admin key compromise
- Governance attack on RDNT
- Systemic risk in DeFi composability
- A pegged stablecoin like DAI could de-peg
- Liquidation risk if LTV ratio isn’t maintained below Liquidation Threshold
- If RDNT price were to drop, it’s possible the earned rewards APR from borrowing could be less than the interest rate to borrow, meaning I would want to close the position.
Step 1: First, I go to the Radiant app markets to check which stablecoins are earning more in RDNT rewards for borrowing vs the borrowing interest rate for that market.
I will use DAI as collateral and borrow <75% LTV in DAI to avoid liquidation risk since DAI debt will track the DAI collateral price.
Currently, I earn 2.56% in lending interest + 2.09% in RDNT for supplying DAI. I also earn 13.22% APR in RDNT for borrowing DAI while paying 6.62% APY–netting me ~7.9-8% APR for every 100 DAI I supplied and 75 DAI borrowed.

Step 2: Next, on the Deposit tab, I proceed to choose the DAI option, specify how much DAI and follow the prompts to Approve and Deposit my DAI collateral.

Step 3: On the Borrow tab, I choose the option to borrow DAI on Arbitrum at a variable borrowing rate of 6.62% APY while earning 13.2% APR in RDNT rewards.
Later, I could even repeat this cycle of borrowing only to redeposit and borrow, to increase my net yield earnings, given borrowing DAI is “safer” from liquidation.

Step 4: Lastly, I’ll need to go to Manage RDNT and click Start Vesting or else my earned RDNT rewards won’t begin vesting for 28 days, which I can come back to claim later.

Earn Up To 19% APR With Sommelier Finance’s ‘Real Yield’ Cellar

Sommelier Finance is a DeFi protocol that provides a non-custodial framework for a wide array of automated yield optimization strategies.
Built using the Cosmos SDK and launched in August 2022, Sommelier allows retail investors to invest in dynamic vaults, called Cellars, run by professional portfolio managers, but without the centralization risks usually associated with such strategies.
User funds are deployed on major Ethereum DeFi protocols using a bi-directional bridge. By running the majority of strategy calculations off mainnet and batching transactions, Sommelier is able to avoid paying excessive Ethereum transaction fees.
How It Works
A Cellar is a smart contract that represents a specific DeFi strategy proposed and implemented by a Strategy Provider. The Cellar is then able to adjust its positioning based on real-time changes in market conditions to maximize yield for liquidity providers.
Looking at an example from the project’s documentation, let’s say we’re looking to earn yield by lending stablecoins on Aave.
Usually, one would just pick the stablecoin with the highest Supply APR at the time of opening the position, and no further action would be taken.
With Sommelier, yield is maximized by “continually analyzing APYs, volatility, liquidity, transaction fees and trends in order to optimally select which stablecoin asset is most profitable to lend.”
What does that mean in practice?
The strategy might start by lending USDC, for example, because it offers the highest yield, but could switch to DAI or USDT in the event of those markets offering better yields.
When market conditions change, Strategy Providers send recommendations to modify their Cellar’s positioning.
If two-thirds of the Sommelier validators agree with the recommendation, a relayer sends a transaction from the Sommelier blockchain across the Gravity bridge to the Cellar on Ethereum to make the necessary changes.
Real Yield USD
In this tutorial, we’re going to look at the Real Yield USD Cellar that’s managed by Seven Seas Capital.
This particular strategy accepts DAI, USDT and USDC and aims to maximize yield through a combination of lending stablecoins on Aave and Compound along with providing liquidity on Uniswap V3 in optimized tick ranges.

From an end-user perspective, Sommelier is quite simple to use.
Let’s dive in.
Step 1: Head over to Sommelier and deposit stablecoins
https://app.sommelier.finance/strategies/Real-Yield-USD/manage
Click on the ‘Buy’ button.
Note that you can deposit USDC, DAI or USDT but will save some gas if you deposit the strategy’s active asset.

Enter the amount you wish to deposit and confirm the transaction.
Step 2: Bond your tokens to earn SOMM rewards
Once your purchase transaction is confirmed, you’ll need to bond your tokens in order to earn SOMM liquidity mining rewards. If you miss this step, you will only earn the strategy’s base yield.
Note that the current LM program is due to end in 22 days.
