Bridged USDC Standard Contracts Now Available on Polygon zkEVM

Polygon zkEVM has officially integrated the Bridged USDC Standard, a framework developed to streamline the future transition of Layer 2 blockchains to native USDC. This initiative addresses the "cold start problem" faced by newer EVM-compatible chains, where bridged stablecoins are essential to bootstrap activity until native versions become viable.

What Is the Bridged USDC Standard?

The Bridged USDC Standard, introduced by Circle, provides a specification for deploying bridged USDC tokens that can later be upgraded seamlessly to native USDC by Circle. This ensures:

• Liquidity unification across networks
• Future-proof compatibility for upgrades
• Reduced fragmentation risks during transitions

Key Benefits for Polygon zkEVM

1. Smooth Migration Path: Legacy bridged USDC will be phased out in favor of standard-compliant tokens.
2. Developer Readiness: Contracts are pre-configured for eventual native USDC support.
3. User Protection: Prevents liquidity splits during future upgrades.

Migrating to Standard-Compliant Bridged USDC

Polygon zkEVM currently hosts two versions of bridged USDC:

• Legacy (Deprecated): 0xA8CE8aee21bC2A48a5EF670afCc9274C7bbbC035
• New (Standard-Compliant): 0x37eAA0eF3549a5Bb7D431be78a3D99BD360d19e5

Migration Process

1. 1:1 Swaps: DeFi protocols on Polygon zkEVM will soon enable direct swaps from legacy to new USDC.

2. Programmatic Support:

   • L1 Escrow: 0x70E70e58ed7B1Cec0D8ef7464072ED8A52d755eB
   • Minter/Burner: 0xBDa0B27f93B2FD3f076725b89cf02e48609bC189
   • NativeConverter: 0xd4F3531Fc95572D9e7b9e9328D9FEaa8e8496054
