v1.7.1

A patch release with one fix that matters: a request the wallet could not
simulate used to be a question nobody could answer. Each item links to its
commit, where the full reasoning lives.

• A request stays reviewable when its chain cannot simulate.
  28db8ce
  A queued request was only ever shown to you once a fresh simulation had
  produced a prepared transaction envelope. Where the endpoint cannot simulate
  at all, that never happened — and the row was not merely un-approvable, it
  could not be rejected either, because review failed before the screen was
  reached. The only exit was for the agent to withdraw it, and anyone funded on
  such a chain had no in-app route to move their money. The block was never the
  transaction: every field of the envelope except one already comes from the
  RPC, and the single missing input is the gas limit. That is all this restores,
  from eth_estimateGas, bounded by the block gas limit read from the same
  endpoint in the same breath and passed through the same ceiling, multiplier,
  and intrinsic floor as before. Only a direct call is sized this way — a batch
  would be estimated against a delegation the account does not hold yet. Nothing
  is loosened: a request rescued this way can only ever reach a human and can
  never sign on its own, and what you are shown still carries the simulation
  findings, so you decide knowing the simulation did not run. A plan that
  genuinely reverts still fails, and still reports its own failure rather than
  an estimation error.

• Monad is no longer a default network.
  c5d70c8
  Its RPC does not implement eth_simulateV1 without transaction validation —
  the form the wallet sends, and the form the specification defaults to — so
  nothing on Monad could be simulated, and therefore nothing could be signed.
  Shipping it as a default offered a network the wallet could not transact on.
  It stays in the registry under the same name and alias and can still be
  configured for reads, and it becomes a default again as soon as an endpoint
  answers the method.

Warning

Windows and Linux key-storage warning: The current builds use per-user credential services that do not isolate raw account keys or the database key to Ekubo Wallet. Same-user malware, including a prompt-injected local agent that can execute programs, can extract those keys and bypass wallet policy and review. Read the security model before installing.
