Important Migration Update for Oasis Sapphire Chain Users Holding USDC, USDT, and wETH

1 min readJul 24, 2025

Dear Oasis Chain community,

As you may know, Router Protocol recently experienced a security incident that affected a subset of assets on the Oasis Sapphire Chain. You can read the full incident report here.

As part of our recovery plan, we’re initiating a token migration process for users who hold USDC, USDT, or wETH on Oasis Sapphire Chain. If you hold any of these assets on Oasis Sapphire, please read the instructions below carefully and complete the process within the next 4 weeks.

What You Need to Do

To ensure a smooth and secure migration, follow these steps:

  1. Burn your affected tokens
    Send your USDC, USDT, and wETH on Oasis Chain to the burn address below:
    0xB1b64005B11350a94c4D069eff4215592d98F2E2
  2. Receive your tokens back on Ethereum
    Within 72 hours of the burn, the equivalent amount will be airdropped to your same wallet address on the Ethereum chain.

Important Notes

-Only the following assets are eligible for migration:

  • USDC: 0x97eec1c29f745dC7c267F90292AA663d997a601D (6 decimals)
  • USDT: 0x8C4aCd74Ff4385f3B7911432FA6787Aa14406f8B (6 decimals)
  • wETH: 0xB6dc6C8b71e88642cEAD3be1025565A9eE74d1C6 (18 decimals)

-Do not send any other assets. Tokens outside of these three are not affected and will not be refunded.

-This migration process will be open for 4 weeks, so please ensure you complete the migration on time.
