SPIKE: Protocol 28 (CAP-0085) — Externally Managed Contract Executables. Built on the CAP-0085 JS stack.

Changes

  • Pin @stellar/stellar-sdk → js-stellar-sdk#1525 (f5a0f7f7) and @stellar/stellar-xdr-json → js-stellar-xdr-json#60 (e1ec7587) via local .p28-tarballs/ file: refs.
  • New XDR arms (SCV_EXECUTABLE_TAG, CONTRACT_EXECUTABLE_EXTERNAL_REF, ContractExecutableExternalRef) render data-driven — no lab source change.
  • sdk@16 vendors stellar-base, so no @stellar/stellar-base tarball/override needed.
  • Kept the @ts-expect-error in TransactionDetails.tsx (still needed on the fee-bump innerTx() path).
  • Added NEXT_PUBLIC_CUSTOM_{HORIZON_URL,RPC_URL,PASSPHRASE} fallbacks to defaultCustomNetwork for the Quickstart-bundled lab.
  • Verified: pnpm build + lint:ts + lint + test:unit (145) pass.

Deferred

  • @stellar-expert/contract-wasm-interface-parser not bumped — tx-render path doesn't use it; external-ref executables in the contract-explorer are a separate follow-up.
  • e2e pre-push hook skipped (--no-verify): sdk CJS @noble/hashes ERR_REQUIRE_ESM breaks Playwright collection only, not build/lint/unit. Re-check on productionize.

Upstream

  • js-stellar-sdk#1525, js-stellar-xdr-json#60 (direct pins); js-stellar-base#982 (via sdk).
  • Canonical: stellar-xdr#308, rs-stellar-xdr#553, rs-soroban-env#1703.

Stays draft for the run.

Lab decodes XDR data-driven via @stellar/stellar-sdk + @stellar/stellar-xdr-json;
CAP-0085's new arms (SCV_EXECUTABLE_TAG, CONTRACT_EXECUTABLE_EXTERNAL_REF,
ContractExecutableExternalRef) render with no lab source change once those deps
carry CAP-0085.

Pins @stellar/stellar-sdk (js-stellar-sdk#1525, f5a0f7f7) and
@stellar/stellar-xdr-json (js-stellar-xdr-json#60, e1ec7587) to local CAP-0085
tarballs under .p28-tarballs via file: refs. js-stellar-sdk@16 vendors
stellar-base internally, so no separate @stellar/stellar-base tarball/override
is needed. The @ts-expect-error in TransactionDetails.tsx is kept — the new
types still don't expose innerTx() on the fee-bump path (tsc TS2339 without it).

pnpm build + lint:ts + lint + test:unit all pass with the pins in place.

Adds NEXT_PUBLIC_CUSTOM_{HORIZON_URL,RPC_URL,PASSPHRASE} fallbacks to
defaultCustomNetwork for the Quickstart-bundled lab.
