When setting up a custom stablecoin there are a number of steps to complete in the onboarding process.
  • Chain: Which chain you wish to deploy your custom stablecoin.
  • Token Name: Name of the token.
  • Token ID: Ticker symbol of the token.
  • Token Logo: What image will show up in your app and tracking websites (32x32 pixels)
  • Reserves Strategy: What percentage of your assets you want to hold in cash v.s. treasuries (money market funds). We typically hold ~20% cash to start depending on the nature of your business. For more details, see the Reserve Management section of the docs.
  • Refundable Deposits: The dollar value of xUSD you want to hold in “inventory” so that your end users will be able to swap quickly (without additional minting/burning).
  • Stablecoin type (Open Loop, Closed Loop, or USDB): For more details, see the section below.

​
Supported Chains

Bridge-issued stablecoins can be minted on a wide range of blockchains such as:
  • Base
  • Ethereum
  • HyperEVM 
  • Linea
  • Polygon
  • Solana
  • Sui
  • Tempo
  • and additional chains added based on demand 

​
Multi-chain deployments

Bridge enables you to deploy your stablecoin on multiple chains. When you deploy on multiple chains (e.g., Ethereum + Base), you get:
  • Same ticker symbol (e.g., “xUSD” on all chains)
  • Same backing (shared reserve pool ensures 1:1 backing across all chains)
  • Cross-chain equivalence (1 xUSD on Ethereum = 1 XUSD on Solana)
  • Separate smart contracts (each chain has its own contract address)

​
Open Issuance Stablecoins

Bridge’s Open Issuance framework allows you to issue your own branded stablecoin while benefiting from powerful network effects. As new stablecoins join the Open Issuance network, overall liquidity expands for everyone. Your users will be able to instantly swap 1:1 between any Open Issuance stablecoins on-chain with zero fees and no intermediary, unlocking unprecedented interoperability.

​
Types of Bridge-issued Stablecoins

Bridge offers three stablecoin options, each designed for different use cases and distribution strategies. Your choice depends on whether you want maximum distribution and interoperability (open loop), controlled circulation within your ecosystem (closed loop), or immediate deployment with zero configuration (USDB).

​
Open Loop 

Open Loop stablecoins are public, permissionless, and highly interoperable across the Bridge ecosystem and beyond, maximizing distribution, growth, and customizability. Key Benefits:
  • Permissionless trading across DeFi protocols and wallets
  • Instant swaps with other Open Issuance stablecoins
  • Multi-chain deployment for broad reach
Examples of leading projects that have launched open loop stablecoins with Bridge include Phantom CASH, MetaMask mUSD, and Native Markets’ USDH. Learn More: Read the Open Issuance blog post to understand how the framework enables 1:1 swaps, shared liquidity, and network effects. Open Loop stablecoins are public, permissionless, and highly interoperable across the Bridge ecosystem and beyond, maximizing distribution, growth, and customizability.

​
Closed Loop

Closed Loop stablecoins operate within a specific ecosystem or platform, providing controlled distribution with enhanced oversight. These private stablecoins are designed to only be used within your platform, giving you maximum control over supply, distribution, and usage. When to Use:
  • Treasury management and internal accounting
  • Platform-specific use cases requiring contained circulation
  • Controlled distribution environments
  • Simplified compliance for restricted ecosystems
  • Testing stablecoin functionality before expanding to open loop
Partners who have built custom closed loop stablecoins include Dakota with DKUSD and Takenos with TAKO.

​
USDB

For users who aren’t yet ready to design their own stablecoin, but still want to get started using stablecoins quickly, Bridge provides an off the shelf solution. Learn more in the next section about USDB.
