Wrap ANY signed Base transaction (transfer, approve, contract call) in a Cobalt validity transaction: Base holds it dormant until your conditions hold, then includes it — a good-till-block/conditional order, no limit-order contract, nobody holding it. We validate the predicates and return the base_sendRawTransactionValidity request; we never touch funds or keys. Conditions: beforeBlock, fromBlock, flashblockIndex, minNativeBalanceWei, or a storage predicate for price. One required.

How these numbers are made
Each listing is called on a schedule without paying. Listings with usage or a verified owner are checked about every 30 minutes, others about every 6 hours. Uptime is the share of passing checks over 30 days, averaged across this provider's listings. Trust scores follow the published method. The figures on this page can be a few minutes behind the latest checks, and listings hidden after review aren't counted.
