Odaily Planet Daily reports that Bitcoin News posted on X that MARA’s Slipstream is now available as an open, permissionless public service without requiring client software. This service is particularly critical for users transferring funds from vulnerable COLDCARD wallets. Multisig spending transactions expose all public keys and spending conditions; if such a transaction enters the public mempool, attackers can immediately compare these keys against their precomputed database of weak COLDCARD private keys and broadcast a higher-fee double-spend transaction before confirmation, provided they control a majority of the keys. Slipstream submits transactions directly to miners, preventing them from entering the public mempool before being mined. MARA recommends using conservative fees to avoid transaction stalling. In addition to standard Bitcoin network fees, this service is currently free.
