[Binance Subsidy Drives USD1 Supply Surge, Solana Becomes Largest Growth Chain] On-chain analyst Yu Jin tweeted that the stablecoin USD1 has seen its total supply increase from approximately $3.3 billion to $4.4 billion, a rise of about $1.1 billion, since Binance launched its subsidy program at the end of January. Citing on-chain data, the author noted that the primary growth came from Solana: USD1's supply on Solana was around $160 million before the program and is now approximately $880 million, an increase of about $720 million. The remaining $380 million in growth is distributed across BSC and Ethereum. Currently, USD1 supply is largely concentrated on these three chains.
