Can I Add StableChain to MetaMask?
Yes, you can easily add StableChain, a USDT-native, EVM compatible blockchain, to your MetaMask wallet. Since it maintains full EVM compatibility, it uses the standard Ethereum address format and smart contract logic. This allows a smooth integration without any complex workarounds.
MetaMask requires a few key parameters to connect to any non-Ethereum network like Stable. You will need to obtain the official Network Name, Chain ID: 988, and the secure RPC URL. This enables your wallet to interact with the StableChain network and manage your assets.
How to Connect StableChain to MetaMask
Connecting the StableChain network to your MetaMask wallet takes less than two minutes once you have the necessary network parameters, through DefiLlama's ChainList.
Follow these steps to complete the manual network addition:
- Visit ChainList: Navigate your browser to the ChainList website, and ensure your MetaMask is unlocked and prepared for connection.
- Connect Wallet: Click the "Connect Wallet" button on the ChainList homepage, and then approve the connection request that appears within your MetaMask extension.
- Search for Stable: Use the search bar to locate the network you wish to add, specifically searching for the "Stable" network using its name or Chain ID 988.
- Add to MetaMask: Once you locate the correct network, click the "Add to MetaMask" button and approve the transaction prompt to complete the network addition.

StableChain Mainnet RPC and Chain ID
Configure MetaMask with the following verified StableChain Mainnet network details:
- Network Name: Stable Mainnet
- RPC URL: https://rpc.stable.xyz
- Chain ID: 988
- Currency Symbol: gUSDT
- Block Explorer: https://stablescan.xyz
StableChain Testnet RPC and Chain ID
Use these official Stable Testnet settings for development and safe experimenting in MetaMask:
- Network Name: Stable Testnet
- RPC URL: https://testnet-rpc.stable.stable.xyz
- Chain ID: 2201
- Currency Symbol: gUSDT
- Block Explorer: https://testnet.stablescan.xyz
What Assets Does StableChain Support?
StableChain creates a unique environment where USDT serves as the primary native asset for value transfer. Users utilize gUSDT to pay for network gas fees, eliminating the friction of holding volatile tokens just to process standard stablecoin payments.
The network also features the STABLE token, which functions exclusively as the governance and staking asset. Holders delegate STABLE to validators to secure the chain and vote on protocol upgrades, ensuring decentralized management without complicating the payment experience.
As an EVM-compatible blockchain, Stable supports all standard ERC-20 and ERC-721 assets. This architecture allows developers to easily deploy applications and users to bridge major cryptocurrencies like ETH or WBTC, creating a diverse ecosystem alongside its stablecoin core.

Is Adding StableChain to MetaMask Safe?
Adding StableChain to MetaMask is generally safe, largely due to backing from established entities like Tether and Bitfinex. Users must strictly verify the network details against official documentation to avoid dangerous phishing scams or potential exploits.
Stable utilizes institutional-grade infrastructure and holds partnerships with custodians like Anchorage Digital. Since specific public audit reports and active bug bounties are not yet prominently listed, you should proceed with caution and monitor their official channels.
About StableChain
StableChain is a newly released Layer 1 blockchain built on a delegated Proof-of-Stake consensus model. Its primary function is to serve as a fast settlement network for stablecoins, positioning USDT as the primary native asset for all on-chain activity.
The network employs a specialized consensus mechanism known as StableBFT, which is engineered to achieve sub-second transaction finality. This focus on speed and security makes the chain highly effective for real-time institutional settlement and reliable, fast retail payment processing.
Despite its focus on stablecoins, the chain supports full EVM compatibility for all smart contracts and dApps. Governance is managed by the STABLE token, which is staked by validators to secure the network and allow holders to vote on all future protocol upgrades.

Final Thoughts
Adding StableChain to MetaMask is the first step toward using this dedicated stablecoin ecosystem. Your configuration is now fully ready for efficient digital payments and institutional settlement.
Next, acquire the native gas token, gUSDT, and bridge assets onto the network. Use the official Stable bridge to move your USDT or compatible tokens onto the Stable Mainnet.
Once assets are on StableChain, explore its unique features and dApps like staking. Look for opportunities to earn yields and engage with Stable’s institutional partners.
Frequently asked questions
What makes StableChain different from Ethereum or Solana?
StableChain (stable.xyz) is unique because it is purpose-built solely for stablecoin payments, unlike general-purpose chains. It uses USDT for gas fees, provides sub-second finality, and offers zero-cost peer-to-peer transfers, optimizing for financial use cases.
How does the gUSDT gas token work, and is it a separate token?
The gUSDT gas token is not a separate asset but rather the name for USDT when used to pay transaction fees. The network's smart account abstraction converts your regular USDT into gUSDT for predictable, dollar-denominated costs.
What is StableBFT, and how does it ensure fast transactions?
Stable uses StableBFT, an optimized Delegated Proof-of-Stake consensus mechanism. This BFT (Byzantine Fault Tolerance) approach is designed for low latency, guaranteeing finality in sub-second times, which is critical for institutional settlement.
Is the native STABLE token required to pay for transaction fees?
No, the STABLE token is not required for paying any transaction fees. It is exclusively the network's governance token used for staking, securing the chain, and voting on protocol upgrades through the Stable Foundation.
