Modular Security
ISM Marketplace
The ISM Marketplace is a registry of Interchain Security Modules (ISMs) that lets developers customize how their messages are verified. Application teams can choose ISMs based on their security, latency, and cost requirements (i.e., using stricter verification for high-value messages and lighter ISMs for routine transfers).
The marketplace includes both standard ISMs from Abacus Works, and community-contributed ISMs developed by partner teams and community members.
