Instant Web3 Payments
Secure lines-of-credit across any blockchain
About 4Mica
4Mica is a lightweight overlay that enables services to extend cryptographically backed lines of credit across any blockchain, from Bitcoin and Ethereum to Solana and beyond. Acting as a credit layer for instant, low-friction settlements and built on guaranteed fair exchange, 4Mica fixes Web3’s inefficient pre-funded model. In short, 4Mica makes programmable credit accessible to all.
