Bridge assets to Quai Network using the Symbiosis cross-chain protocol. Symbiosis enables seamless transfers between Quai and other major networks including Ethereum and Base. Note: USDT bridging from Base to Quai is not currently available. For USDT, use Ethereum → Quai.

​
Key Contract Addresses

Use these exact addresses when bridging to avoid interacting with the wrong tokens.

​
Add Token to Wallet

Use the buttons below to add the QUAI token (Symbiosis representation) to your wallet on Base or Ethereum. Make sure your wallet (e.g., MetaMask) is installed. The button will switch to the correct network and prompt an “Add Token” dialog.

Integration Notes

  • CoinGecko Platform ID: quai-network
  • Gas Token ID: quai-network
  • Quai uses the Cyprus1 zone for cross-chain operations
  • Transactions on Quai use standard EVM-compatible signing for the account-based (Quai) token
USDT is not currently available as a native token on Quai Network. When bridging USDT from other chains, it will be represented as a synthetic asset through the Symbiosis Synthesis contract.
