Three ways to move money: Transactions (instant, wallet or card funded, including Cash-In for in-person cash deposits), Deposit Addresses (reusable crypto deposit configurations), and Virtual Accounts (dedicated bank accounts that auto-convert fiat to crypto). Standard transactions follow a two-step flow: create a Quote (pricing), then create a Transaction (execution). Cash-in codes generate a one-time deposit code for in-person cash deposits at retail locations. contact: name: Polygon OMS url: https://oms.polygon.technology servers: - url: https://sandbox-api.polygon.technology/v0.12 description: Sandbox - url: https://api.polygon.technology/v0.12 description: Production security: - BearerAuth: [] tags: - name: Auth description: Authentication via FrontEgg - name: Customers description: Customer management and KYC - name: Customer - name: Wallet - name: Quote - name: Transaction - name: CashIns - name: CashLocation - name: Sandbox - name: VirtualAccount - name: Counterparty - name: ExternalAccount - name: Reference - name: DepositAddress paths: /deposit-addresses/{depositAddressId}: patch: tags: - DepositAddress summary: Update a Deposit Address description: >- Update a Deposit Address.

Fiat arms (`bankUs` / `bankIban` / `bankCanada`) deliver to a registered bank-type External Account (`cryptoToFiatAccount`). The `walletExternal` crypto arm delivers crypto onward to a registered wallet (`cryptoToCrypto`), gated by the routes table to Erebor-serviceable networks (ethereum/base/solana — Polygon is rejected). `walletExternal` is registered-only (`ext_wlt_` EA id; raw blockchainAddress stays Cash-In-only). `walletCrypto` is declared but NOT currently supported as a destination: it is rejected with 422 `destinationWalletCryptoNotSupported`. Use `walletExternal` for externally-held wallets. (Planned to return for non-custodial wallets in v0.12.) The `walletFiat` arm (v0.12) delivers converted fiat into the customer's own Erebor fiat wallet via an internal book transfer (`cryptoToFiatAccount`; the resolved destination instrument reads `network: bookTransfer`). The wallet must belong to the DA's customer (422 `walletCustomerMismatch`), be `active` (422 `walletNotActive`), and hold `usd`; the project must have the `book_transfer` outgoing rail enabled (403 `destinationRailNotAllowed`). The reused side arms carry an optional `amount`, which is meaningless for a standing destination and rejected at validation. The server validates the side `details` (asset/network/accountHolder) against the resolved EA/wallet.

CryptoNetwork: type: string enum: - ethereum - polygon - base - solana description: >- Wire vocabulary for a crypto `network` request field: ethereum, polygon, base, solana. This is vocabulary, not availability — which of these a given destination type actually accepts is enforced at runtime per destination type against the narrower Erebor-served set, so `polygon` is legal on the wire but currently rejected wherever Erebor does not serve it. Numeric EVM chain ids (e.g. "1", "137", "8453") were never accepted by BPN — no chain-id-to-name coercion exists, so nothing here deprecates prior behavior. Values are lowercase on the wire; the server additionally normalizes case and surrounding whitespace on input, so this schema is stricter than the server in that one dimension — send lowercase, untrimmed-safe values to stay strictly schema-valid. A `network` field may be typed `CryptoNetwork` regardless of whether it appears on a response, as long as its sole writer is gated by `eanetworks.AllServedNetworks()` — a runtime-enforced subset of this enum, with the containment itself enforced by `TestCryptoNetwork_SupersetOfServedNetworks` (services/externalaccount/networks/networks_test.go). That guarantee is what makes the enum safe there: the value can never leave the enum's vocabulary no matter which code path renders it. A `network` field whose writer is NOT so gated stays `string` pending #2666's outbound enum guard — for such a field, a stored value outside the enum would break a strict partner client validator (this happened in production: #2528). `chain` fields are deliberately excluded too: their vocabulary is wider and includes `bitcoin`, which this enum does not carry.

HONORED TODAY ON: a Deposit Address `bankUs` destination with `network: "wire"` (create and update). The stored value replaces — it does not append to — the memo OMS would otherwise generate for every outbound Fedwire payout from that deposit address. Send `null` (or omit it on an update that replaces `destination`) to restore the generated memo. Because the memo is read when each payout wire is built, an edit affects only future payouts, never one already in flight. REJECTED EVERYWHERE ELSE, with `422 memoNotSupported`: this model is shared by the Quote and Virtual Account request surfaces (create and update), and by a deposit-address `bankUs` destination on the `ach` / `achSameDay` rails. A non-empty memo on any of those is refused rather than accepted and dropped — a silently ignored field on a money path gives the caller a success response while the payout carries the generated memo. Sending `null`, omitting the field, or sending only whitespace is always accepted (it means "no override"). Each rejected surface becomes accepting as its slice ships (omsx#2254); relaxing a 422 into an accepted value never breaks a caller, so no client needs to change when that happens. The error body's `details.reason` tells apart a temporary gap from a permanent one: `"notImplemented"` means this surface/rail will accept the field once its omsx#2254 slice ships (every current rejection above is this case); `"unsupportedRail"` would mean the field is not a concept on this rail and never will be (e.g. the shared model also carries fields that are rail-specific by design, like ACH's `companyDiscretionaryData` on a wire destination) — retry the first after a release, never the second. companyDiscretionaryData: type: string allOf: - $ref: '#/components/schemas/companyDiscretionaryData' nullable: true description: >- Optional ACH-only field for the originator's internal use (NACHA batch header).

Allowed characters are the ISO 20022 set only: letters, digits, space and `/?:().,'+-`. `maxLength` is the ISO 20022 OUTER bound (140), which is what Fedwire and SWIFT accept. Per-rail rules are enforced server-side rather than in the schema. Note that ACH is not simply shorter: the NACHA addenda record is a different character set (uppercase only, no `/`, but `&=@_#%` allowed) capped at 80, so the two sets overlap without either containing the other. The pattern below MUST stay byte-identical to `iso20022.CharsetPattern` (`lib/iso20022/charset.go`), the Go-side authority the request validators and the outbound memo builders share. `TestCharsetPatternMatchesTypeSpec` reads this file and fails if the two drift. x-go-type: string companyDiscretionaryData: type: string maxLength: 20 pattern: ^[A-Z0-9 &\-\.\$*\/#@%]*$ description: |- Optional ACH-only field for the originator's internal use, carried verbatim in the NACHA batch header (companyDiscretionaryData). Distinct from `memo`: this never reaches the beneficiary, it is BPN's own origination metadata. Uppercase NACHA character set, max 20 characters.
