🟢 Perform transactions About Onchain The last cosigner confirms the transaction (txn) that executes on-chain. The on-chain txn pays the network fee and is recorded in the cosigner's address history. If the cosigner does not have enough funds for the txn fee the txn can fail with txn fees lost. Limits and queue There are no time limits to sign txns. Transaction queueNo other txn can be executed until the current txn is executed, canceled, or replaced.
