feat: add send generic input by brunomenezes · Pull Request #438 · cartesi/rollups-explorer

brunomenezes · 2026-02-27T14:51:58Z

Summary

The code changes in this PR achieve feature parity in terms of a user be able to send transactions (i.e. deposits through portals and generic input through the input box).

Even though the add-input is the simplest in terms of smart contract interface, it was the last to be added as it depends on the PR #434 (ABI encoding/decoding support), since we provide ways for the user to choose how they want to send the data i.e. using a raw hex value, or a string to be converted to hex, or ABI encoding to define the input to be sent.

PS: Currently I am skipping the CI step to publish the test reports to coveralls. It is having service outage for a couple of days at the moment of writing. They don't have an ETA, more details here: https://status.coveralls.io/

closes: #435

Pull request overview

Adds support in the Dave webapp to send generic inputs to an application via the Cartesi InputBox, with multiple input encoding modes (raw hex, string-to-hex, and ABI-based encoding) to reach feature parity with existing “send” flows.

Changes:

Introduces a new GenericInputForm with validation, ABI/spec selection, and encoding helpers.
Wires “Input” into the Send menu/modal and passes JSON_ABI specifications into the form.
Temporarily disables publishing Coveralls reports in CI.

Typo in data-testid: empty-inputs-argments-alert should be empty-inputs-arguments-alert to avoid propagating the misspelling into tests and tooling.

apps/dave/src/components/send/SendMenu.tsx


 type SendMenuProps = { application: Application };

+const jsonAbiOnly = (spec: DbSpecification) => spec.mode === "json_abi";


jsonAbiOnly is a boolean predicate, so filter(jsonAbiOnly, ...) does not narrow the DbSpecification union type. That forces as casts later and makes it easy to accidentally pass non-JSON_ABI specs. Consider making jsonAbiOnly a proper type guard and/or mapping the list to the exact {id, name, abi} shape expected by GenericInputForm.

Suggested change

const jsonAbiOnly = (spec: DbSpecification) => spec.mode === "json_abi";

const jsonAbiOnly = (

spec: DbSpecification,

): spec is Extract<DbSpecification, { mode: "json_abi" }> =>

spec.mode === "json_abi";

The current is fine. Later there will be a refactoring and the GenericInputForm may be removed.

apps/dave/src/components/send/SendModal.tsx

+                    application={state.application}
+                    specifications={
+                        state.specifications as GenericInputFormSpecification[]
+                    }


This cast hides the fact that DbSpecification is a union (some variants do not have an abi field). If anything other than mode: "json_abi" slips into state.specifications, GenericInputForm will break at runtime. Prefer narrowing the type earlier (e.g., store only JSON_ABI specs in state) or mapping to the GenericInputFormSpecification shape without using as casts.

It is fine by the reason above. The list of specifications from the state is expected to be already filtered by Specs with mode json_abi.
