MakerDAO / Sky vs Radiant Capital

Sky functions primarily as an autonomous collateralized debt protocol built natively on Ethereum and expanding across supported Layer 2 networks. The foundation of the system revolves around decentralized vaults where participants deposit eligible crypto assets, including Ether (ETH), wrapped Bitcoin (WBTC), staked Ether (stETH), and selected real-world asset allocations, to mint stablecoins. Following the protocol overhaul, participants have access to both the established DAI stablecoin and the upgraded USDS asset, alongside Maker (MKR) and Sky (SKY) governance tokens.

Depositors seeking yield allocate USDS into the Sky Savings Rate or DAI into the DAI Savings Rate module without relinquishing custody to third-party custodians. These savings modules accrue interest programmatically, pulling revenue generated from active borrowing stability fees and institutional collateral backing the balance sheet. Token holders can execute 1:1 conversions between DAI and USDS or convert MKR to SKY at a fixed 1:24,000 ratio directly through the official user interface or via decentralized exchange liquidity pools.

The system additionally introduces SubDAO structures, known as Stars, designed to decentralize specific operational tasks, regional lending markets, and customized token economics. This multi-token structure provides diverse yield pathways but demands careful tracking of token utility, contract migrations, and individual collateralization criteria across each specific vault category.

Radiant Capital operates as a decentralized, non-custodial money market that leverages LayerZero messaging formats to facilitate omnichain borrowing. Instead of restricting collateral and loan origination to a single isolated network, Radiant enables a user to deposit a supported blue-chip token on one chain, such as Arbitrum, and borrow an entirely different asset on another network, like Ethereum mainnet or BNB Chain. This architecture aims to reduce the friction, execution delays, and bridge wrapping steps typically associated with moving assets manually between separate decentralized finance ecosystems.

The asset catalog focuses primarily on high-liquidity foundational tokens. Supported collateral and borrowable assets commonly include stablecoins such as USDC, USDT, and DAI, alongside major cryptocurrencies including wrapped Bitcoin, wrapped Ethereum, and native network tokens. Each asset pool operates with distinct risk parameters, loan to value ratios, and liquidation thresholds determined by governance models. The primary utility and governance asset, RDNT, functions alongside the core money markets to distribute protocol fee shares to users who lock dynamic liquidity pairs, establishing an incentive layer that supplements standard pool utilization interest.

Operating on Sky involves several variable cost components rather than flat platform subscription fees. Borrowers minting USDS or DAI pay an annualized stability fee, which is a dynamic interest rate calculated continuously against the notable debt balance. Stability fees vary substantially depending on the deposited collateral type, risk profile, and broader macroeconomic liquidity targets set by DAO token governance voters. Volatile collateral assets generally carry higher stability rates than conservative multi-collateral allocations.

When a borrower's collateral value falls below the mandatory liquidation threshold, the smart contract initiates an automated Dutch auction liquidation mechanism. Liquidation penalties apply, charging borrowers a percentage fee on top of the liquidated collateral required to cover the notable stablecoin debt. These liquidation penalties range between roughly 5 percent and 15 percent depending on the specific vault parameter, making conservative over-collateralization essential for debt positions.

Depositing into the savings module does not incur native management or withdrawal fees. However, because the primary contract operations settle on the Ethereum base layer, network gas fees apply to every transaction, including token approvals, deposits, compounding claims, and withdrawals. During periods of elevated blockchain congestion, gas costs can erode net yields for smaller balance allocations, favoring larger capital deposits or Layer 2 execution routes where available.

Fees on Radiant Capital are fundamentally algorithmic, reflecting real-time supply and demand dynamics across individual asset pools. Suppliers earn variable interest rates driven by pool utilization, meaning rates rise automatically as borrowing demand increases. Borrowers pay variable interest rates corresponding to the utilization curve of the borrowed pool. In addition to variable base interest rates, transactions on Radiant require native blockchain gas fees on the originating and destination chains to execute smart contract operations and LayerZero cross-chain messages.

To access RDNT emission rewards and receive a share of protocol platform fees, participants must interact with the Dynamic Liquidity Provision mechanism. Users lock liquidity pool tokens, typically RDNT paired with ETH or BNB, representing at least a specified percentage of their total supplied collateral value. Protocol revenue generated from borrower interest and liquidation penalties is distributed to eligible locked liquidity providers in primary assets like stablecoins and native tokens. Withdrawing supplied liquidity remains non-custodial and flexible, provided the user maintains an account health factor safely above the liquidation threshold, while locked liquidity tokens remain subject to predefined vesting and locking terms.

Sky operates on a non-custodial framework where assets remain locked inside audited smart contracts rather than managed by a corporate entity or pooled custodial exchange. Participants control their private keys through self-custody Web3 wallets, retaining sovereign authority over withdrawals provided their vault remains properly collateralized. The protocol does not enforce identity verification, know-your-customer checks, or account registrations to interact with the underlying open-source smart contracts.

Protocol parameters, risk limits, stability fees, and supported collateral types are governed by SKY and MKR token holders through decentralized executive voting and governance polls. To mitigate emergency exploitation vectors, the protocol uses governance security modules that implement time delays between proposal approval and contract execution. This operational buffer provides market participants with time to react, exit positions, or adjust balances if contentious parameter adjustments occur.

Despite comprehensive formal verification and numerous external security audits conducted across multiple years, self-custody smart contract systems carry inherent risks. Technical vulnerabilities, oracle pricing failures, extreme chain-level liquidations, and unexpected balance sheet composition shifts in underlying backing assets represent systemic exposures that cannot be fully eliminated by code helps protect alone.

Because Radiant Capital is an autonomous decentralized finance protocol, custody of deposited funds remains governed entirely by smart contracts rather than a centralized intermediary. Users retain self-custody through their connected Web3 wallets, interacting directly with open-source smart contract pools. The protocol relies heavily on LayerZero omnichain messaging contracts to track balances, collateral ratios, and cross-chain execution states. This multi-layered architecture introduces composite risk, as security depends not only on Radiant core contracts but also on external bridging infrastructure and network oracles.

To manage operational risk, Radiant implements automated liquidation mechanisms supported by third-party price oracles like Chainlink. When collateral values drop or accrued interest pushes an account health factor below the liquidation threshold of 1.0, external liquidators can repay a portion of the notable debt in exchange for seized collateral at a liquidation penalty discount. Users must proactively monitor collateral ratios through self-directed controls and alerts, particularly during periods of steep market volatility. Smart contracts undergo external security reviews, yet interaction inherently involves risk exposure to potential software bugs, oracle latency, and cross-chain messaging vulnerabilities.

At the foundational smart contract level, Sky remains globally accessible to any wallet connected to supported EVM-compatible networks. However, front-end access via the official sky.money web application enforces geographical terms of service restrictions. The hosted user interface blocks visitors originating from specific jurisdictions, including the United States, sanctioned territories, and restricted regions, due to evolving regulatory frameworks surrounding digital asset services.

Because Sky is a decentralized protocol rather than a traditional financial intermediary, customer support functions differ significantly from centralized financial platforms. There is no central helpdesk, phone support, or ticketing department capable of reversing errant blockchain transactions, recovering lost private keys, or modifying personal vault configurations. Users rely on community-managed forums, Discord channels, public governance documentation, and technical knowledge bases for operational guidance.

Prospective users must recognize that interacting with decentralized finance interfaces requires technical self-reliance. While alternative community front-ends and direct contract interactions exist outside the primary web portal, navigating these tools demands familiarity with Web3 wallet security, RPC network configurations, and decentralized trade routing.

Access to Radiant Capital is permissionless at the smart contract level, enabling users globally to connect compatible Web3 wallets directly to the decentralized application. However, the user interface hosted on web domains may apply geographic restrictions or screening policies to comply with regulatory standards across specific jurisdictions. Users are solely responsible for ensuring that their use of decentralized lending products aligns with local financial laws, tax reporting mandates, and token trading regulations in their home region.

Customer support on Radiant follows standard decentralized finance conventions, functioning primarily through community-driven channels rather than dedicated enterprise help desks. Assistance is available through structured documentation, community forums, and official communication platforms such as Discord. Because the protocol is autonomous and non-custodial, support staff and community moderators cannot intervene in transactions, reverse failed transfers, recover lost private keys, or alter liquidation outcomes. Users are expected to maintain technical proficiency regarding transaction signing, gas estimation, slippage tolerances, and self-custody wallet management before executing complex omnichain loan positions.
