Ten-minute review

This page exists so a reviewer does not have to guess where the substance is. It is written for someone judging whether the Stellar work is real, in about ten minutes.

Read, in this order

What Stellar decides about the design · 2 min

Architecture overview. Two properties of Stellar shape the whole system: MEMO_HASH is exactly 32 bytes, and anchors settle on Stellar itself. Everything else follows from those.

The reference, and why there is no indexer · 2 min

Corridor Reference and ADR 0003. 32 bytes, carried whole in the signed transaction. Reconciliation is a join on a watched account’s own payment stream, with a stored paging token — not an index. The page also states the one case where the anchor assigns the memo instead.

Anchors as the fiat spokes · 2 min

SEP anchor interface and ADR 0006. SEP-1, 10, 12, 38 and 31 behind the same partner interface as any other provider. Note what the SEP-10 adapter checks before the vault signs, and that SEP-6 collections are unimplemented rather than stubbed.

What the books guarantee · 2 min

Ledger and ADR 0012. Double-entry, append-only, exactly-once per external movement, and 7 decimal places so a booked balance can equal an on-chain balance exactly. rescale refuses any conversion to a 6 dp spoke that would drop a stroop.

What has actually run · 1 min

Evidence. Two Stellar testnet runs on 17 October 2026, both on stellar.expert, both reproducible with one command each. The prototype’s mainnet payout is there too, labelled as the prototype’s.

What is not built · 1 min

The list below, and Roadmap.

Run, in this order

pnpm install
pnpm test                 # 298 tests, no network
pnpm stellar:wallets      # creates and funds two testnet vaults
pnpm stellar:smoke        # a real payment, reference read back off Horizon
pnpm stellar:payout       # the whole saga: route, reserve, fund the anchor, book it

For the SEP path against a server Corridor does not control, ./examples/anchor/up.sh brings up Stellar’s own Anchor Platform and the same payout script runs against it.

stellar:smoke is the shortest proof that the reference survives a real Stellar transaction: it sends a payment with the reference as MEMO_HASH, reads the payment back off Horizon, and decodes the reference out of the memo. stellar:payout runs the same thing inside the saga engine, against a mock anchor on the Stellar chain, and prints the ledger invariants at the end.

The three files worth opening

File	Why
`packages/chain-stellar/src/stellar.test.ts`	The reference on a real transaction, issuer identity, and the Horizon quirks that would otherwise lose every memo
`packages/routing/src/routing.test.ts`	Hub enforcement and every route shape, as tests
`packages/partners/src/sep.ts`	The anchor over SEP-1/10/12/38/31, including the challenge check before the vault signs

What is not built

This is the whole list, stated plainly so nothing below has to be inferred.

Not built	What that means
No anchor is signed	No real local currency has moved on Stellar. The SEP path has run end to end against Stellar’s own Anchor Platform, run locally (`examples/anchor`), not against a licensed anchor.
SEP-6 collections	`openCollection` checks the anchor publishes a `TRANSFER_SERVER` and then raises, rather than guessing at a flow no signed anchor has exercised.
The `cctp.transfer` leg	Declared in the route graph and planned for, but not written, so mainnet naira payouts do not run. Testnet uses `bridge.simulated`, whose Stellar side is real.
MGUSD, PYUSD and USDT issuers	Deliberately unset until each is verified against the issuer’s own `stellar.toml`. Asking for one raises an error that names the missing issuer.
The treasury console	Not built for Stellar. The prototype’s console read Tempo and Solana and was removed rather than left reporting a chain this repo no longer settles on. Read-only reporting runs from `pnpm watch:report`.
A mainnet run	The code paths are identical; nothing has run on Stellar mainnet.

What came before

Corridor’s earlier prototype settled on Tempo and reached its payout rails through bespoke provider APIs. It paid ₦3,891.48 into a Nigerian bank account 74 seconds after 2.90 USDC.e left a vault, on 11 October 2026. That build lives in its own repository; this one is Stellar-native, and the Tempo, Across, Zcash and NEAR packages were deleted rather than left dormant. The prototype’s result is kept on the Evidence page, labelled as the prototype’s, because it is where the saga engine, the ledger and the reconciliation matcher were proven against real money.
