IBC Interoperability

Native IBC

c8ntinuum’s native cross-chain protocol is IBC (Inter-Blockchain Communication). IBC provides trust-minimized cross-chain messaging backed by light-client verification. Access IBC directly from Solidity via the ICS02 and ICS20 precompiles.

IBC Safety Controls

c8ntinuum has two custom IBC control modules:

Control	Scope	Reference
IBC breaker	Operator-controlled `ibc_available` flag that blocks selected outbound IBC initiation paths, including `MsgTransfer`, when disabled.	IBC Breaker
IBC rate-limiter extension	Governance-managed whitelist for operators that can add, update, remove, or reset IBC rate limits. Packet enforcement remains with the ratelimiting middleware.	IBC Rate-Limiter Extension

The IBC breaker is not a full token-transfer freeze. Internal non-IBC transfers, such as bank MsgSend, remain available when it is disabled. The ICS20 precompile transfer path routes into the transfer keeper, so it is blocked when ibc_available=false. For broader chain availability control, see the Circuit Breaker. It gates native Cosmos transactions, EVM extension transactions, and eth_sendRawTransaction submissions when system_available=false.

Infinity Interop

For routes to chains outside IBC, the Infinity hub exposes quote, order and status endpoints under /v1 and a typed TypeScript client. Start at the API overview or the Quickstart.
