Add the 11 currencies account-types.ts already supports

[shreyav]

Summary

currencies.ts had drifted behind account-types.ts. Eleven account types had specs but no currency entry — AED, BDT, BWP, COP, EGP, GHS, GTQ, HTG, JMD, PKR, XAF.

That's not cosmetic. The picker iterates currencies, and CurrencySelection.accountType is only ever set from FiatCurrency.accountType or CryptoAsset.accountTypes[].type. A currency absent from this file cannot be selected, so its corridor cannot be built, previewed, or code-generated at all. Takes the list from 26 entries to 37.

This became more consequential after #776: rails are now sent to the API as destination.paymentRail, so entries have to carry real PaymentRail enum values, not display strings.

Where the rails came from

Each currency's rails are taken from its paymentRails enum in openapi/components/schemas/common/<Ccy>AccountInfo.yaml — the authoritative list of what that account type supports. Not inferred from the account-type field shapes, which only hint at it.

Currency	Rails
AED, GTQ, JMD	BANK_TRANSFER
BWP, HTG, XAF	MOBILE_MONEY
BDT, COP, EGP, GHS, PKR	BANK_TRANSFER, MOBILE_MONEY

None of the eleven has an instant rail, so all carry instantRails: []. That has a behavioral consequence worth confirming: jitEligible is computed as instantRails.length > 0, so none of these currencies will offer just-in-time funding. That matches the schemas, but it's the kind of thing worth a second opinion from someone who knows the corridors.

Flags

Eight of the eleven had no flag asset, and getIconSrc returns /flags/<code>.svg unconditionally — they would have rendered broken. Added ae, bd, co, eg, gt, ht, jm, pk.

Sourced from circle-flags, which is already a dependency and is where the existing 39 came from — I verified an existing flag is byte-identical to the package's copy before using it, so these match the current set exactly rather than merely resembling it.

Also adds sv.svg, which fixes a pre-existing bug. The El Salvador entry has referenced a flag that was never committed, so it renders broken on main today. Unrelated to the eleven, but it's a one-file fix in exactly the area this PR touches. Happy to split it out if you'd rather keep the diff clean.

REGION_SHORT

Added the eight new two-letter codes in InputCard.tsx. Its lookup is REGION_SHORT[region] ?? region, so a missing entry already degrades to the raw currency code — this is display polish, not a fix. getCountryName in flow-path.ts needed nothing: its countryCode.toUpperCase() fallback already produces exactly the GT-style output its map contains.

Verification

Checked mechanically across the whole file, not just the new rows:

• Strict typecheck of currencies.ts — clean
• All 11 accountType values exist in account-types.ts
• Every rail in the file is a valid PaymentRail member
• Every countryCode in the file now resolves to a flag that exists

Not verified: no build or render check. npm ci fails here because @central-icons-react requires CENTRAL_LICENSE_KEY. The Vercel preview is the real check — worth eyeballing the picker for the 11 new rows and their flags.

Judgment calls to second-guess

• accountLabel for dual-rail currencies. Used "<Country> Bank Account", following CNY_ACCOUNT. The other dual-rail precedent, SLV_ACCOUNT, uses "El Salvador Bank/Mobile". Mixed precedent in the file; I picked the more common form.
• AED uses accountLabel: 'IBAN', matching EUR and DKK, because its account type is IBAN-based rather than account-number-based.
• XAF uses countryCode: 'cm' (Cameroon) for a multi-country CFA zone, mirroring how XOF uses 'sn'.
• Example people are invented, following the file's existing convention of one plausible local name per currency.

Related

Fills the currencies.ts half of the drift found while triaging the stale docs-sync PRs. The remaining known gap in this area is surfacing SWIFT_ACCOUNT, which needs FiatCurrency widened beyond a single accountType plus a fiat account-type dropdown — see closed#775 for the schema research.

Greptile Summary

The PR brings the flow builder’s fiat-currency catalog into sync with its supported account types.

• Adds eleven selectable fiat currencies with account types and payment rails matching the OpenAPI schemas.
• Adds the required country flag assets, including the previously missing El Salvador flag.
• Extends compact region labels for the newly introduced currency codes.

Confidence Score: 5/5

The PR appears safe to merge, with the newly exposed currency metadata matching the authoritative account types and payment rails.

The added account types exist in the current API contract, every configured payment rail matches its corresponding schema, non-instant rails remain ineligible for JIT funding, and the required flag assets are present.
