## Proposal Summary This proposal formally requests that **Stable** be recognized as a canonical chain within the Uniswap V3 deployment framework. The intent is to acknowledge the already-deployed Uniswap V3 contract suite on Stable, with Stable Swap ([swap.stable.xyz](https://swap.stable.xyz/)) serving as a standalone, actively maintained frontend that routes trades through this deployment. By doing so, the Uniswap DAO would extend canonical coverage to a USDT-native, high-throughput Layer 1 purpose-built for stablecoin payments, while requiring no additional technical work beyond updating the canonical deployments registry. ## Proposal Stakeholders - **Proposer** : Protofire / website: [https://protofire.io](https://protofire.io/) / X (Twitter) handle: [https://x.com/protofire](https://x.com/protofire) - **Deployer** : Protofire - **Bridge Provider** : LayerZero ([https://layerzero.network](https://layerzero.network/)) ## About Stable Stable is a high-throughput, EVM-compatible Layer 1 “StableChain” purpose-built for USDT and stablecoin settlement. It treats USDT as a native gas asset, enabling gasless transfers, ultra-low fees, and sub-second finality for dollar-denominated transactions. Designed as institutional-grade infrastructure, Stable combines predictable performance, regulatory alignment, and dedicated blockspace to support real-world payments, remittances, and high-volume institutional flows. The network targets 10,000+ TPS and provides confidential transfer capabilities tailored to institutional use cases. ### Key Attributes - **USDT-native design** : USDT as gas, gas-free transfers, and real-dollar settlement optimized for stablecoin flows. - **High throughput & low latency** : Engineered for high-frequency volume with sub-second finality and a roadmap towards 10,000+ TPS. - **Institutional-grade infrastructure** : Focus on compliance, predictable performance, dedicated blockspace, and confidential transfers for enterprises, fintechs, and payment providers. - **EVM-compatible** : Solidity and Ethereum tooling work out-of-the-box, easing Uniswap V3 deployment and integration with existing DeFi infrastructure. - **Backed by major ecosystem players** : Supported by Bitfinex, Tether, and additional strategic investors, Stable conducted a pre-deposit campaign capped at $1.325 billion. ### Target Audience Stable is targeting: - **Payment and remittance providers** seeking predictable, low-cost USDT rails for cross-border payments and merchant settlement. - **Fintechs, neobanks, and PSPs** that require compliant, enterprise-grade infrastructure with dedicated blockspace, confidential transfers, and integration-friendly tooling. - **DeFi-native users and builders** who want to deploy and trade stablecoin-centric strategies (delta-neutral, basis trades, stablecoin LPs) on a chain optimized for USDT liquidity. - **Everyday users and merchants** who want “cash-like” USDT payments (gasless, sub-second settlement, single-currency UX) without juggling volatile gas tokens. ## Bridge - **LayerZero** — [https://layerzero.network](https://layerzero.network/) LayerZero provides the cross-chain messaging and bridging infrastructure connecting Stable with Ethereum and other Uniswap-relevant ecosystems, enabling secure movement of assets and messages between canonical Uniswap deployments and Stable. This allows liquidity providers and integrators to bridge assets and orchestrate multi-chain strategies while routing trades through the canonical Uniswap V3 deployment on Stable. ## Benefits to Uniswap By formally recognizing Stable as a canonical Uniswap V3 deployment, the Uniswap DAO gains exposure to a USDT-native, payments-centric Layer 1 that is explicitly designed to scale global stablecoin usage. This deployment can attract new liquidity from payment rails, fintechs, and institutions building on Stable, while preserving Uniswap’s familiar EVM-based integration surface. The combination of gasless USDT transfers, sub-second settlement, and high throughput creates an ideal environment for deep, capital-efficient stablecoin liquidity, reinforcing Uniswap’s position as the default exchange infrastructure for the emerging “stablecoin economy” and extending the protocol’s reach into real-world payments use cases. ## Stable DEX Environment Stable is being designed first and foremost as rails for real-world money movement, with USDT as the native unit of account and gas asset. Within that context, the DEX layer is expected to support not just retail trading, but institutional-grade DeFi integrations and tokenized yield products that require deep, reliable, and composable liquidity. Stable Swap is the canonical Uniswap deployment on Stable and the default venue for spot liquidity. Its primary role is to act as the base liquidity and routing layer for the ecosystem, with a design focus on: - **Institutional-grade DeFi integrations** - **Tokenized yield products and vaults** Other DEX deployments on Stable are purpose-built to complement, rather than replace, Stable Swap: - **Curve** - **SettleX** ## Frontend This deployment is a standalone instance of Uniswap V3, exposed through a dedicated frontend called Stable Swap, with active maintenance and long-term support from Protofire and the Stable ecosystem. The UI is designed to be the default Uniswap experience on Stable, integrating seamlessly with wallets and payment flows on the chain. ![image](https://us1.discourse-cdn.com/flex016/uploads/uniswap1/original/2X/4/4143864ec2b6689f23329d439c284f6d2824d33c.png) The production frontend is live at: [https://swap.stable.xyz](https://swap.stable.xyz/) ## Smart Contracts Below is a table with all contract addresses. | Contract Name | Address | | --- | --- | | v3 Core Factory | [0x88F0a512eF09175D456bc9547f914f48C013E4aA](https://stablescan.xyz/address/0x88F0a512eF09175D456bc9547f914f48C013E4aA) | | Multicall 2 | [0x208099D6E8a107aD485CD1374A6EC5Abd98c7F11](https://stablescan.xyz/address/0x208099D6E8a107aD485CD1374A6EC5Abd98c7F11) | | Proxy Admin | [0x51D1E70B8cAbDF4F3aB056475802AB1687b3EA23](https://stablescan.xyz/address/0x51D1E70B8cAbDF4F3aB056475802AB1687b3EA23) | | Tick Lens | [0x8dF0D1614aae99352045c62d24d54E72b38111ec](https://stablescan.xyz/address/0x8dF0D1614aae99352045c62d24d54E72b38111ec) | | NFT Descriptor Library V1.3.0 | [0xF7815833076D83161414A46c4E993dC8f22A7ADd](https://stablescan.xyz/address/0xF7815833076D83161414A46c4E993dC8f22A7ADd) | | Nonfungible Token Position Descriptor V1.3.0 | [0x7Cf5987951E48ADf235cc9194bCdc708Eb692D82](https://stablescan.xyz/address/0x7Cf5987951E48ADf235cc9194bCdc708Eb692D82) | | Descriptor Proxy | [0xcd2cD0E139eC5581138E18C6DBB189c53efBAE95](https://stablescan.xyz/address/0xcd2cD0E139eC5581138E18C6DBB189c53efBAE95) | | Nonfungible Token Position Manager | [0x3BdC3437405f7D801b6036532713fc1F179136a6](https://stablescan.xyz/address/0x3BdC3437405f7D801b6036532713fc1F179136a6) | | v3 Migrator | [0x2C5f4275F1a278BF328D56CB9db304e915DE3082](https://stablescan.xyz/address/0x2C5f4275F1a278BF328D56CB9db304e915DE3082) | | v3 Staker | [0xA32e3E127FF46db40ab3c4775be97ED760AD7178](https://stablescan.xyz/address/0xA32e3E127FF46db40ab3c4775be97ED760AD7178) | | Quoter V2 | [0xb070179E7032CdA868b53e6C1742F80c9e940d1A](https://stablescan.xyz/address/0xb070179E7032CdA868b53e6C1742F80c9e940d1A) | | Swap Router02 | [0x32eaf9B5d5F2CD7361c5012890C943D7de84C22a](https://stablescan.xyz/address/0x32eaf9B5d5F2CD7361c5012890C943D7de84C22a) | | V2 Core Factory | [0x25D2d657F539F2bB16eC82773cBE5ee49ddD3c69](https://stablescan.xyz/address/0x25D2d657F539F2bB16eC82773cBE5ee49ddD3c69) | | Uniswap V2 Router02 | [0xa571dc7c4f2369F1cA24D3a7E8a35c07Ff52bfC0](https://stablescan.xyz/address/0xa571dc7c4f2369F1cA24D3a7E8a35c07Ff52bfC0) | | Permit2 | [0x000000000022D473030F116dDEE9F6B43aC78BA3](https://stablescan.xyz/address/0x000000000022D473030F116dDEE9F6B43aC78BA3) | | Universal Router | [0x5Be52b52f3d1dbC324d2959637471a4208626144](https://stablescan.xyz/address/0x5Be52b52f3d1dbC324d2959637471a4208626144) | ## Timeline This deployment is already live, fully operational, and actively maintained: the core Uniswap V3 contracts are deployed on Stable, routing through the Stable Swap frontend, with bridge connectivity via LayerZero and an ongoing commitment from Protofire and ecosystem partners to sustain and grow usage over time. ---

We agree with making Stable canonical. That being said, we feel a lot of the metrics backing this are missing from the proposal. We were wondering if there were any KPIs of this canonical proposal, past achievements, or metrics of its current deployment? ---

Although the latest UC term has concluded, the deployment efforts pertaining to the Stable deployment began in Q4 of last year. We are therefore concluding that process now. This proposal has successfully completed the approval period, canonicalizing the associated contracts as the official deployments on Stable. The contracts are verified, and ownership of the factory contracts have been successfully transferred to Uniswap governacne. The UC will update registries in accordance with this approval.
