Symbiosis has added Circle's Arc mainnet to its any-to-any cross-chain routing. Arc is built by Circle on USDC gas with institutional block producers, targeting payments and tokenised markets rather than speculation. Users can now route to and through Arc along with Symbiosis's other supported chains.
Symbiosis disclosed a security incident on Sep 11, 2026 at approximately 04:28 UTC, when an attacker exploited a vulnerability in its Bitcoin Bridge. As a result, all BTC routes were halted immediately.
Only the Bitcoin Bridge was affected; other routes remain operational and safe. The team has not yet detailed the extent of any loss or compensation plans.
Symbiosis said Bitcoin swaps are back online — but currently routed through partners Chainflip and THORChain, not its own infrastructure. The Symbiosis Bitcoin Bridge remains paused following the incident affecting its BTC portal, and the team says it will share a separate update once the bridge is restored.
Symbiosis has unveiled a redesigned logo, marking the brand's first visual refresh after five years on the market. The protocol highlights that it has moved over $10 billion across millions of transactions and users to date.

Symbiosis now supports swapping into cbZEC and cbHYPE from any chain and any token. Users can bridge into these Coinbase-wrapped assets directly through the protocol without needing to hold them on a specific network first.
Symbiosis has fully completed its protocol maintenance, with all cross-chain swaps now back to normal operation, including BTC in/out routes after they were briefly paused during the final stretch of the work. This confirms the full restoration promised in the earlier update.
Symbiosis has opened a community vote on whether to bring Arc Chain to the platform, asking users to vote on the proposal. Arc Chain's addition would be decided by the outcome of the live vote.
Symbiosis is deprecating and delisting several chains. Support for Arbitrum Nova will be discontinued after August 23, following the ArbitrumDAO's vote to transition Arbitrum Nova into a maintenance-oriented state. Starting August 24, Symbiosis will delist Core DAO, Arbitrum Nova, B² Network, Kava EVM, ZetaChain, and Morph from the protocol. Users holding liquidity or open positions on these chains are advised to withdraw their funds before the cutoff.
