 ## IBC Errors
 
-### IBC packet timeout
-**Cause**: The IBC packet was not relayed within the timeout window.  
-**Fix**: Implement a reclaim flow. After timeout, the user can reclaim their tokens:
-```bash
-seid tx ibc-transfer timeout-packet [timeout-packet-details] --from mykey
-```
-Always communicate to users that IBC transfers can timeout (rare, but possible).
+### An IBC transfer fails or reverts
+**Cause**: IBC is closed on Sei in both directions — inbound by Props 116/120, outbound by [Proposal 121](https://seistream.app/proposals/121) (2026-07-31). The `ibc` module rejects the transfer regardless of channel, recipient, or amount. This applies to `seid tx ibc-transfer transfer` and to the IBC precompile (`0x…1009`) equally.
+
+**Fix**: There is no IBC route on or off Sei. Do not retry, adjust the timeout, or try another channel. Use an EVM bridge instead — see [../ecosystem/bridges.md](../ecosystem/bridges.md).
+
+Existing `ibc/...` balances are **not** stuck: they remain in the bank module and still transfer between Sei accounts and through their ERC-20 pointers. Only the route off the chain is closed. See [../ecosystem/ibc-bridging.md](../ecosystem/ibc-bridging.md).
 
 ### `IBC denom not recognized`
-**Cause**: The receiving chain doesn't know the `ibc/HASH` denom.  
-**Fix**: Query the denom trace to find the original denom:
+**Cause**: A consumer doesn't know what an `ibc/HASH` denom represents. These denoms still exist and are still valid on Sei.  
+**Fix**: Query the denom trace — this is a local query and still works:

-## Why IBC is legacy on Sei
+## Current parameter state
 
-Sei is EVM-first as of SIP-3. IBC operated on the **Cosmos side** of Sei using `sei1...` addresses. With inbound IBC disabled, the only relevant flow is *exiting*: holders of legacy `ibc/...` assets (e.g. USDC.n bridged via Noble) must move them off the Cosmos side — swap to native USDC (bridge out via CCTP) or transfer out — before the upgrade fully activates. Migration routes and the affected-asset table are in https://docs.sei.io/learn/sip-03-migration.
+Both governing parameters are `false` on mainnet:
 
-## IBC mechanics (for exit / historical context)
+```
+cosmos/params/v1beta1/params?subspace=ibc&key=InboundEnabled  -> "false"
+cosmos/params/v1beta1/params?subspace=ibc&key=OutboundEnabled -> "false"
+```
 
-An IBC transfer is relayed packet-by-packet; assets arrive as `ibc/<hash>` denoms. To send a Cosmos-side asset **out** of Sei to another Cosmos chain:
+Query them directly rather than trusting a proposal page, since a later proposal could change either one:
 
 ```bash
-# Transfer tokens from Sei to another Cosmos chain (exit flow)
-seid tx ibc-transfer transfer \
-  transfer \                          # port
-  channel-0 \                         # channel (e.g. Sei→Osmosis)
-  <RECIPIENT_ADDRESS> \
-  1000000usei \                       # amount + denom
-  --from <YOUR_KEY> \
-  --chain-id pacific-1 \
-  --node https://rpc.sei-apis.com \
-  --fees 20000usei \
-  --timeout-timestamp $(date -d "+1 hour" +%s)000000000
+seid q params subspace ibc InboundEnabled  --node https://rpc.sei-apis.com
+seid q params subspace ibc OutboundEnabled --node https://rpc.sei-apis.com
 ```
 
-Resolve what an `ibc/...` denom represents:
+## What this means for existing balances
+
+**Legacy `ibc/...` assets are not gone, and they are not frozen.** They remain in the bank module and behave like any other native denom *inside* Sei:
+
+- They still appear in `seid q bank balances <sei1...>`.
+- They still transfer between Sei accounts.
+- They still work through their ERC-20 pointer contracts, so EVM contracts can still read and move them.
+- They can still be swapped on a Sei DEX, subject to that DEX having liquidity for the pair.
+
+What is closed is the **redemption path**: there is no way to send an `ibc/...` asset back to its origin chain, and no way for a new one to arrive.
+
+Resolving what a denom represents still works — that is a local query, not a transfer:
 
 ```bash
 seid q ibc-transfer denom-trace <IBC_HASH> --node https://rpc.sei-apis.com
 ```
 
-Check current channels at https://www.mintscan.io/sei/relayers.
+## What is no longer possible
 
-## IBC precompile (legacy)
+- Sending assets **out** of Sei over IBC. `seid tx ibc-transfer transfer` fails — the module rejects outbound transfers regardless of channel, recipient, or amount.
+- Receiving assets **into** Sei over IBC from any Cosmos chain.
+- The exit and migration routes Sei previously documented for legacy holders. Noble/CCTP for `USDC.n` and Skip:Go for ATOM and WBTC all depended on outbound IBC and no longer function.
+- Opening or recovering IBC channels and light clients for asset-transfer purposes.
 
-The IBC precompile (`0x0000000000000000000000000000000000001009`) exposed IBC transfers to the EVM for CosmWasm-adjacent workflows. It is **legacy** — CosmWasm is deprecated (SIP-3) and inbound IBC is disabled, so it is not a path for new builds. The interface is documented for completeness only:
+Anything phrased as "migrate your IBC assets before the proposal activates" is **out of date** — that window closed with Proposal 121.
 
-```solidity
-interface IIBC {
-    function transfer(
-        string memory toAddress, string memory port, string memory channel,
-        string memory denom, uint256 amount,
-        uint64 revisionNumber, uint64 revisionHeight, uint64 timeoutTimestamp,
-        string memory memo
-    ) external payable returns (uint64 sequence);
-}
-```
+## IBC precompile (`0x…1009`) — do not use
+
+The IBC precompile at `0x0000000000000000000000000000000000001009` exposed IBC transfers to the EVM. **Its `transfer` function cannot succeed now that outbound IBC is disabled.** Do not include it in new contracts and do not present it as a bridging option; existing contracts that call it will revert on that path.
+
+For cross-VM asset access that *does* still work — moving native SEI, factory tokens, and existing `ibc/...` denoms between the EVM and Cosmos layers within Sei — see the Bank and Pointer precompiles in [../precompiles/cosmwasm-bridge.md](../precompiles/cosmwasm-bridge.md).
 
-## New bridging → use the EVM bridges
+## For new bridging → use the EVM bridges
 
-For omnichain tokens, wrapped assets, native USDC, or cross-chain messaging, use the EVM bridges. The canonical, Sei-documented patterns are **LayerZero V2 OFT** and **Circle CCTP v2** — addresses/EIDs live in [bridges.md](bridges.md) and on https://docs.sei.io/evm/bridging/layerzero. (Wormhole supports SeiEVM per its own network list but is not documented by Sei — verify first; see [bridges.md](bridges.md).) End users can bridge through the official [Sei bridge dashboard](https://dashboard.sei.io/bridge) or an embedded Thirdweb widget (https://docs.sei.io/evm/bridging/thirdweb).
+| Need | Use |
+|---|---|
+| Omnichain token across EVM chains | **LayerZero V2 OFT** |
+| Native USDC | **Circle CCTP v2** |
+| Coverage LayerZero/CCTP lack | **Wormhole NTT/WTT** — verify first, not documented by Sei |
+| End-user bridging UI | [Sei bridge dashboard](https://dashboard.sei.io/bridge) or the [Thirdweb widget](https://docs.sei.io/evm/bridging/thirdweb) |
 
-## Bridge checklist
+Addresses, EIDs and the full comparison are in [bridges.md](bridges.md).
 
-- [ ] Do **not** plan inbound IBC — it is disabled (SIP-3). Use an EVM bridge.
-- [ ] For legacy `ibc/...` holdings, plan the **exit** before SIP-3 fully activates (CCTP for USDC).
+## Checklist
+
+- [ ] Do **not** plan any IBC transfer, inbound or outbound. Use an EVM bridge.
+- [ ] Do **not** tell a holder to bridge, migrate, or exit `ibc/...` assets — there is no route.
+- [ ] Do tell them their balances are intact and still usable within Sei.
+- [ ] Do **not** call the IBC precompile (`0x…1009`) in new contracts.
 - [ ] Verify any bridge is audited and has significant TVL before integrating.
 - [ ] Test the full round trip on testnet (atlantic-2) first.
 - [ ] For LayerZero: deploy + wire your OFT on both chains before launch; quote the native fee with `quoteSend`.
 - [ ] Use legacy `gasPrice` for Sei-side claim/redeem transactions (no EIP-1559 base-fee burn).
+
+## Historical context
+
+IBC operated on the **Cosmos side** of Sei using `sei1...` addresses, with assets arriving as `ibc/<hash>` denoms relayed packet-by-packet by third-party relayers. Sei is EVM-first as of SIP-3, and the chain no longer participates in IBC in either direction. Running an IBC relayer for Sei is therefore no longer a viable role — see [participation-roles.md](participation-roles.md).
