Gateway: New Pre-Mint Address for USDC on Solana

‍

Ahead of mainnet launch for Gateway on Solana, Circle has deployed a new pre-mint address to enable Gateway to programmatically mint USDC on Solana. The new address is: CkzX3bvAt9PcjCh2QoQdM9ENzUVwH229hFe4dB7Y8qZK and the full list of pre-mint addresses are contained within our GitHub repo. For exchanges and websites that track USDC in circulation for Solana, you can continue to use our public API as normal – no action is required.

NOTE: DO NOT ATTEMPT TO SEND USDC TO A PRE-MINT ADDRESS AS IT WILL RESULT IN A LOSS OF FUNDS. PRE-MINT ADDRESSES ARE ONLY INTENDED FOR USE BY CIRCLE.

Pre-minting Details

On some non-EVM blockchains like Solana, Circle uses the concept of pre-minting to create and hold a balance of USDC before it goes into circulation. This is made possible by pre-mint addresses, which hold USDC that is not considered part of the circulating supply until Circle officially authorizes a mint.

How it works:

1. Pre-mint addresses have an existing balance of pre-minted USDC, which is not included in the total amount in circulation.
2. When a user conducts a Gateway mint on Solana, USDC is sent from the pre-mint address to the user's address, increasing USDC in circulation.
