IBC (Inter-Blockchain Communication)

• Back to bostrom infrastructure

Overview

• Bostrom connects to other Cosmos chains via IBC, enabling cross-chain token transfers and interoperability.

Active Channels

Supported Tokens

• Bostrom → Other Chains

• Other Chains → Bostrom

How IBC Works

• 1. Light Clients: Each chain maintains a light client that tracks the other chain's consensus 2. Channels: Ordered or unordered channels for packet delivery 3. Relayers: Off-chain processes that submit proofs between chains 4. Packets: Messages (like token transfers) sent through channels

Using IBC Transfers

• Via cyb.ai

  • Go to https://cyb.ai/teleport to use the IBC bridge interface.

• Via CLI

		  # Transfer BOOT to Osmosis
		  cyber tx ibc-transfer transfer transfer channel-2 osmo1... 1000000boot \
		    --from <key> --chain-id bostrom --fees 5000boot
		  # Transfer BOOT to Cosmos Hub
		  cyber tx ibc-transfer transfer transfer channel-8 cosmos1... 1000000boot \
		    --from <key> --chain-id bostrom --fees 5000boot
		  ```
## Relayer Infrastructure
- The [[cyberia]] team operates an IBC relayer using [[Hermes]] to ensure packets are delivered between chains.
- ### Relayer Features
	- Automatic packet relay (transfers, acknowledgements, timeouts)
	- Client updates to prevent expiry
	- Monitoring and alerting for failed packets
	- Auto-restart on failure
- ### Packet Filtering
	- The relayer only processes Bostrom-related channels for efficiency.
## IBC Client Recovery
- IBC clients can expire if not updated regularly (trusting period). If this happens:
	- 1. A new "substitute" client is created
		  2. A governance proposal recovers the expired client using the substitute
		  3. Both chains must pass the recovery proposal
- ### Recovery Status (Feb 2026)
| Chain | Bostrom Prop | Remote Prop | Result |
|-------|--------------|-------------|--------|
| Osmosis | #32 ✅ | #1002 ✅ | RESTORED |
| Cosmos Hub | #33 ✅ | #1023 ❌ | Failed quorum (36.7% vs 40% needed) |
	- #+BEGIN_WARNING
		  Cosmos Hub IBC requires a new proposal. The previous attempt (#1023) had 92.5% YES but failed due to insufficient voter turnout. Top validators didn't participate.
		  #+END_WARNING
## Troubleshooting
- ### Transfer Stuck
	- IBC transfers have a timeout (usually 10 minutes). If your transfer is stuck:
		- Check if the packet was relayed: query pending packets on the channel
		- Wait for timeout — tokens will be refunded automatically
		- Contact the team if issues persist
- ### Channel Status
	- Check channel state via LCD:
```bash
			  curl -s "https://lcd.bostrom.cybernode.ai/ibc/core/channel/v1/channels/channel-2/ports/transfer" | jq '.channel.state'
			  # Should return: "STATE_OPEN"
			  ```
## IBC Tokens on Osmosis
- BOOT and other Bostrom tokens are available on Osmosis DEX:
	- https://app.osmosis.zone
	- Search for "BOOT" to find trading pairs
