On October 8, blockchain software company Consensys and post-trade infrastructure company ClearToken announced a collaboration aimed at enabling banks to transfer tokenized assets and cash through 24/7 infrastructure. The two parties plan to connect Consensys's blockchain system with ClearToken's regulated post-trade entities for the settlement of eligible securities using fiat currency, tokenized bank deposits, or stablecoins.The announcement did not put a new public blockchain or settlement venue into production but outlined how the two parties plan to connect tokenization, wallets, distribution, cash flow, and the legal finality of securities settlement. Consensys will provide cryptographic finality, which is the technical certainty that on-chain transactions are immutable; ClearToken is responsible for settlement finality, which is the legal certainty that the transfer of funds or securities is final and irrevocable. ClearToken's securities custody has passed Gate 2 of the Bank of England's Digital Securities Sandbox, and its independent clearing entity still requires authorization from the Bank of England.ClearToken CSD Limited plans to convert eligible securities held by different banks into interchangeable tokenized instruments, using the same ISIN as the corresponding traditional securities. At launch, the custody plan will support FTSE 350 stocks, GBP government bonds, GBP corporate bonds, and non-GBP corporate bonds. The sandbox custody limits are set at £600 million for government bonds, £900 million for GBP corporate bonds, and £1.8 billion for non-GBP corporate bonds. The announcement did not name participating banks, networks, wallet products, or the date of the first transaction.
