Technical description
The ixo Blockchain is a Layer 1 blockchain that runs on both Testnet and Mainnet. Prior to version 8.0.0, the x/bonds module moved funds from an address that was resolved from a DID verification method, without verifying that the resolved address belonged to the transaction signer. Affected handlers included MsgMakeOutcomePayment, MsgBuy, MsgSell, MsgSwap, and MsgWithdrawShare, as well as the batch order processor. Because any account may list an arbitrary blockchainAccountID as a verification method on a DID it controls (without the consent of that address's owner), an attacker could register victims' addresses as verification methods on their own DID and then move the victims' balances into a bond the attacker controlled — later withdrawing and bridging the proceeds off-chain. This was exploited on ixo mainnet (ixo-5) on 2026-06-20. The attack required no victim keys, signatures, or system compromise — any account holding a balance in a token a bond could use was at risk. This was fi
