The Solana Foundation has released token extensions for the SPL token standard on the Solana network. These token extensions allow for enhanced token interactions, confidential interactions, and per-exchange token transfer fees, among other features. The token extensions are a new SPL token standard that enhances its original functionality. In dozens of new use cases, including enhanced token interactions, per-exchange token transfer fees, and confidential transfers supported by zero-knowledge proofs, the token extensions are designed to help businesses transition to on-chain operations and provide simplified security, compliance, and other services on the Solana network, according to the company statement.
