Any service deployed on web3 rails lack a capital-efficient, cheap, and non-custodial way to pay in real time.
Current workarounds lead to:
The result: per-task billing is nearly impossible at scale → slowed adoption.

Enables cryptographically-backed "lines of credit"
One yield-generating deposit → backs thousands of instant micro-payments
Configurable TTLs & SLAs, for full flexibility
Settlement automatically enforced on parent chain (no value leakage)
Flexible and composable across any service that accepts crypto
Composable payment infrastructure for APIs, agents, and on-chain services
Deposit in yield-generating vault
Instant access to service
Cryptographic payment tabs
Secure and trustless by design
Time-to-live settings
Risk management
Service agreements
“4Mica is building the missing payment primitive that makes on-chain services commercially viable.”
