$FIXER
Fixer Protocol is a Solana-native payment layer for AI agents that abstracts both the x402 and MPP protocols behind a single API, so an agent can pay for anything with one method while every transaction settles on-chain. It gives agents non-custodial wallets and built-in spend controls, keeps payments transparent and verifiable by default, and offers an optional zero-knowledge privacy mode when amounts and counterparties need to stay confidential.
