Now I have comprehensive information to provide a detailed overview. Let me compile this into a professional research report.
Polygon PoS Bridged DAI (Polygon POS) Cryptocurrency Overview
Core Definition and Technology
Polygon PoS Bridged DAI technically 'lives' on Polygon while being backed 1:1 by DAI held on Ethereum. This represents a bridged version of the native DAI stablecoin, enabling users to access DAI's stability benefits on the Polygon network with significantly reduced transaction costs and faster settlement times.
Core Technology and Blockchain Architecture
Polygon PoS Network Foundation
Polygon PoS is an EVM-compatible Proof-of-Stake sidechain for Ethereum, with high throughput and low transaction costs. Polygon PoS is a high-throughput, low-cost Proof-of-Stake sidechain that checkpoints to Ethereum every ~30 minutes, and is ideal for NFTs, gaming, and retail DeFi, featuring low gas fees and finality in around 2–3 hours.
Bridging Mechanism
The bridge ensures that there is no change to the circulating supply of the token when it crosses the bridge, as the tokens that leave the Ethereum network are locked, and the same number of tokens are minted on Polygon PoS as a pegged token (1:1). Similarly when the tokens are bridged back to Ethereum, tokens are burned on Polygon PoS network and unlocked on Ethereum network during the process.
To move such a token from Ethereum to Polygon PoS, the user needs to lock funds in a contract on Ethereum, and the corresponding tokens are then minted on Polygon PoS. This bridge relay mechanism is run by the Polygon PoS validators who need ⅔ to agree on the locked token event on Ethereum to mint the corresponding token amount on Polygon PoS.
Primary Use Cases and Real-World Applications
Stablecoin Utility
DAI is a price-stable asset that is mostly used as a hedge against volatility as it maintains a stable value of around 1 USD. DAI addresses this problem for crypto native users, as well as enables a wide range of financial activities including hedging during periods of high market volatility, market making against a stable asset, use as collateral for leveraging, and payment as a medium of exchange.
Polygon Network Applications
Polygon has deep DeFi TVL, with Aave, Uniswap, and QuickSwap anchoring liquidity across PoS and zkEVM. Fast finality and low fees make it ideal for borrowing, trading, and yield strategies.
The significant reduction in transaction fees when compared to Ethereum's main network makes Polygon PoS Bridged DAI particularly valuable for frequent transactions and smaller value transfers that would be economically unviable on Ethereum mainnet.
Founding Team, Key Developers, and Project History
DAI and MakerDAO Origins
MakerDAO was formed in 2014 by Danish entrepreneur Rune Christensen. According to Christensen, the name of the cryptocurrency is based on the Chinese character 貸, which he translated as "to lend or to provide capital for a loan". On December 18, 2017, DAI was launched on the main Ethereum network.
Polygon Network Development
The Matic Network was launched in 2017 by four software engineers: Jaynti Kanani, Sandeep Nailwal, Anurag Arjun, and Mihailo Bjelic. Polygon was formed in 2017 by Jaynti Kanani, who currently serves as the CEO, along with Sandeep Nailwal, chief operating officer and cofounder, and Anurag Arjun, cofounder and chief product officer.
Tokenomics: Supply, Distribution, and Mechanics
DAI Supply Characteristics
There is no upper limit on the total supply of DAI — the supply is dynamic and depends on how much collateral is stored in the vaults at any given moment. DAI is minted when users borrow against locked collateral and burned when debt is repaid.
Current Market Metrics
Based on current data, Polygon PoS Bridged DAI demonstrates the following characteristics:
- Market Capitalization: $642.14 million
- Circulating Supply: 642.24 million DAI
- Total Supply: 642.24 million DAI
- Current Price: $0.9995 USD
- 24-Hour Trading Volume: $20.16 million
- Market Rank: #100 globally
Stability Mechanisms
Stability fees are one policy tool that is used to manage the circulating supply of DAI. Decreasing the stability fee, lowers the cost of borrowing, which helps incentivize the minting of additional DAI, while increasing the stability fee has the opposite effect of reducing the rate of DAI creation.
Collateral in Maker Vaults is worth more than the global Dai debt. When Dai is <$1, traders repay their Vaults, reducing Dai supply. When Dai is >$1, traders open Vaults, increasing Dai supply. The opening and closing of Vault positions by arbitrage traders directly affects Dai token supply elasticity.
Consensus Mechanism and Network Security Model
Polygon PoS Consensus
Polygon employs a Byzantine Fault Tolerant (BFT) consensus algorithm called Proof-of-Stake Checkpointing to ensure decentralization and prevent any single entity from gaining excessive control.
Validator Architecture
Validators stake their MATIC tokens as collateral to work for the security of the network and in exchange for their service, earn rewards. The network currently caps the number of active validators at 105, ensuring that only the most reliable and technically capable nodes are part of the network's core.
Security Guarantees
As long as ⅔ of the weighted stake of the validators is honest, the chain will progress accurately. These checkpoints are periodically added to the Ethereum mainnet, providing a secure anchoring point for the Polygon PoS network.
DAI Collateralization
All dai in circulation is at all times backed by at least as much collateral. In fact the system only allows borrowing up to what Maker governance considers to be a safe ratio (currently 150%) so USD $100M of dai in circulation would for example be backed by at least USD $150M of ETH locked in the Maker collateral vault.
Key Partnerships and Ecosystem Integrations
MakerDAO Partnerships
In September 2018, venture capital firm Andreessen Horowitz invested $15 million in MakerDAO by purchasing 6% of all MKR tokens.
Polygon Ecosystem Integrations
In November 2022, JPMorgan Chase executed its first live trade on a public blockchain, using Polygon and modified Aave. By February 2023, the blockchain was doing business with large companies such as Starbucks and Mastercard, with Fortune noting it had been relatively unaffected by the 2022 cryptocurrency crash compared to other companies.
In April 2023, Polygon and Google Cloud have formed a multi-year strategic alliance to accelerate the adoption of Polygon protocols. In January 2025, Jio Platforms, the digital subsidiary of Reliance Industries (RIL) and the operator of Indian-based telecom network, Reliance Jio, confirmed a collaboration with blockchain firm Polygon Labs to integrate Web3 capabilities into its existing applications and services.
Competitive Advantages and Unique Value Proposition
Cost Efficiency
Polygon maintains consistently low transaction fees, typically less than $0.01 per transaction, making it a cost-effective solution for decentralized applications.
Transaction Speed
Polygon's consensus mechanism allows for transaction confirmation in a single block, leading to fast transaction processing speeds. It can handle more than 32 transactions per second on average.
Ethereum Compatibility
Polygon's sidechains are Ethereum-compatible, allowing interoperability with the existing Ethereum ecosystem. Developers can easily migrate their dApps and smart contracts from Ethereum to Polygon using a bridge like ChainPort. Projects built on Polygon can benefit from Polygon's improved scalability while maintaining compatibility with Ethereum.
Decentralized Stablecoin Advantage
Unlike other stablecoins that are typically backed by traditional fiat currency in a centralised bank, DAI is collateralised by cryptocurrencies like Ethereum (ETH) and other Ethereum-based assets approved by MKR holders.
Current Development Activity and Roadmap Highlights
Polygon 2.0 Initiative
The Polygon 2.0 upgrade introduces a modular, multichain framework designed to unify liquidity across all Polygon chains and appchains. Combined with the launch of a 10-year, one billion-token ecosystem grant program, Polygon is investing heavily in long-term developer and protocol growth.
AggLayer Protocol
In January 2024, Polygon announced a new protocol called AggLayer that aims to aggregate zero-knowledge proofs (ZK-proofs) from multiple blockchains and allow developers to connect layer 1 and 2 blockchains to merge them into a single network.
Community Treasury
In January 2024, Polygon announced that its community had voted to fund a new "Community Treasury", with about $640 million worth of tokens to fund grants for projects within the Polygon ecosystem.
