| Solana | Spoke | 30168 | Largest retail base; needs the Solana OFT program build |
Hub and spoke
Spokes peer only with the hub. The hub keeps bridgedOut[eid] for every route and refuses inbound credit above it, so a compromised route can mint at most what legitimately sits on that route. A transfer between two spokes is therefore two transfers: spoke to hub, then hub to spoke.
Fees
| Transfer | Bridge fee |
|---|---|
| Plain KRONOS or wsKRONOS transfer | 0.20% (capped at 0.50% in code) |
| Stake from a spoke | 0% |
| Unstake back to a spoke | 0% |
Network gas and the LayerZero message fee apply to every transfer. The bridge fee goes to the RevenueSplitter on the hub.
Safety
- Every route requires at least 3 DVNs with no optional set, and pins its libraries and executor.
- Rate limits apply in both directions on every route. An unset limit means the route is closed.
- A guardian can pause a route instantly; only the owner, behind a 48-hour timelock, can unpause.
- A watcher compares
bridgedOut[eid]with each spoke's supply and pauses on any mismatch.
