# THORChain reopens Bitcoin and Ethereum swaps Author: Abdullah Özkurt Language: English Published: 2026-11-04T23:47:46+03:00 Updated: 2026-11-04T23:47:46+03:00 ![Turquoise light crosses a transparent coupling between metal conduits bearing Bitcoin and Ethereum symbols, beside a capped branch; a conceptual illustration of reopened swaps.](https://kriptometa.com/uploads/thorchain-de-bitcoin-ve-ethereum-takaslari-yeniden-acildi-6dcb711931b1_article.webp) ## Key takeaways - Bitcoin and Ethereum are among seven chains reopened in the November 4 announcement. - At 20:16 UTC, 103 of 111 active nodes showed the new release and eight remained on the old version. - ATOM and BSC show no trading or payment halt; both restrictions remain active for Solana. THORChain has reopened most swaps halted after an erroneous 10 ETH payment. Developers patched the software nodes use to track transfers on other chains; Solana swaps and outbound payments remain restricted. THORChain has **reopened swaps involving Bitcoin, Ethereum and several other networks following its version 3.21.1 update**. In its November 4 announcement, the team said 14 active nodes still needed to upgrade and asked their operators to install the release. Swaps had been suspended after an Ethereum block change led a vault to pay out an extra 10 ETH on October 31. THORChain is a [decentralized protocol](https://kriptometa.com/en/glossary/decentralized-exchange-dex) for exchanging assets on their native networks. Someone swapping Bitcoin for Ether does not first have to turn BTC into a token on another chain. The protocol uses [liquidity pools](https://kriptometa.com/en/glossary/liquidity-pool) paired with RUNE and vaults managed jointly by nodes; users do not need to hold RUNE for that intermediate exchange. ## Which swaps have reopened and what remains restricted? The team’s [November 4 announcement](https://x.com/THORChain/status/2117799357395202535) listed AVAX, BASE, BCH, BTC, DOGE, ETH, LTC, RUNE, TRON, XRPL and ZEC as open for trading. That list covers ten external networks and THORChain’s native asset, RUNE. Bitcoin, Ethereum, Bitcoin Cash, Dogecoin, Litecoin, TRON and Zcash are the seven networks restored compared with the November 2 list of halted swaps. The announcement still listed ATOM, BSC and SOL swaps as halted. By 20:16 UTC on November 4, however, [Liquify’s THORNodes configuration screen](https://thornode.network/network/config) showed trading, signing and chain-observation halts at zero for Cosmos/ATOM and BSC. Solana nodes could still watch the chain, but swaps and outgoing payments remained on hold. November 4 announcement compared with configuration at 20:16 UTC | Network or asset | Team announcement | Later configuration screen | |---|---|---| | BTC, ETH, BCH, DOGE, LTC, TRON, ZEC | Swaps reopened | Relevant trading and signing halts off | | AVAX, BASE, XRPL and native RUNE | Swaps open | Global trading halt off | | Cosmos/ATOM and BSC | Swaps halted | Trading, signing and observation halts off | | Solana | Swaps halted | Trading and outbound signing remain halted | THORChain operators can [halt swaps and outgoing payments separately](https://dev.thorchain.org/concepts/network-halts.html). If only swaps are halted, nodes can continue watching incoming transfers and sending refunds. A signing halt leaves payments from the vault waiting in a queue. Users need to check whether payments are enabled on the relevant network as well as obtaining a quote in an application. The same screen showed that the periodic rotation of node groups managing vaults was paused. Restrictions on new liquidity deposits into some pools also remained. KriptoMeta read Liquify’s settings display; it did not submit transactions through applications to test access or payment times.

According to the [3.21.1 release notes](https://gitlab.com/thorchain/thornode/-/releases/v3.21.1), developers patched Bifrost, the component that observes transactions on external chains. The rules nodes use to agree on accepted blocks stay the same. Operators can update their own nodes without waiting for a shared activation block. The team distributes a private compiled binary with additional security patches and tells operators to use that package rather than build from source. The release notes provide no independent audit report. An unresponsive peer could previously hold up the software sending transfer observations to other nodes; developers fixed that fault. Nodes can now fetch Ethereum transaction results for a block in one request and retrieve TRON transaction data in batches. The team also fixed how XRP connections time out and retry. On Cosmos/GAIA, they removed IBC deposit observation. They also fixed a stale decoding registry that caused entire transactions to be skipped. The vault-balance checker now uses the network-wide halt setting rather than a local flag. The [Bifrost and vault documentation](https://docs.thorchain.org/technical-documentation/technology/bifrost-tss-and-vaults) explains that each node watches external-chain vaults for incoming transactions. About 67% of nodes must report the same observed transaction before it is accepted. Outgoing payments use [signatures produced jointly](https://kriptometa.com/en/glossary/digital-signature) from key shares held by multiple nodes, rather than a complete key controlled by one operator. The team did not announce a new speed or finality time applying to all swaps after these transfer-tracking fixes. The 14 nodes on older software were the count at the time of the official announcement. In the [active-node table](https://thornode.network/nodes/active) read by KriptoMeta at 20:16 UTC, 103 of 111 records showed version 3.21.1 and eight showed 3.21.0. The table counts nodes; one person or company may operate more than one. ## How did the 10 ETH error happen? In its [November 2 technical account](https://x.com/THORChain/status/2117011632757092501), the team said Ethereum’s accepted block history changed by one block at 11:34 UTC on October 31. A 10 ETH deposit previously observed by THORChain disappeared from the accepted history, but the protocol had already recorded it. When the user’s price limit was not met, the vault refunded 10 ETH it had never received; the real deposit was also refunded. Nodes noticed the block change but could not obtain a clear answer within the time allowed for rechecking the deposit. THORChain treated the transaction as final, leaving a vault shortfall. The automatic balance checker first halted ETH swaps. Node operators then stopped ETH payments and, as a precaution, THORChain activity on other networks. Bitcoin and Ethereum continued producing their own blocks. The team said on November 2 that the user had [returned the extra 10 ETH](https://kriptometa.com/en/thorchain-10-eth-shortfall-swap-halt) and closed the shortfall. It gave no additional repayment or loss figure on November 4. No firm reopening time for Solana swaps or completion time for pending payments was provided. THORChain said the update moved Monero support one step closer to launch. XMR swaps are absent from the list of open networks, and the team has yet to announce a launch date.
