Platform Overview
Product Scope
The Gravv platform provides business customers (tenants) with the following product capabilities, all exposed through a unified REST API and the Gravv dashboard:
Multi-currency internal accounts — tenant and customer accounts backed by Web3 wallets across multiple chains, with fiat virtual accounts attached via banking partners for local-rail deposits.
Cross-border transfers — payouts across African local rails (NGN, GHS, KES, ZAR and others), USD domestic rails (ACH / wire), SWIFT international wires, SEPA, and mobile money, with provider routing per corridor.
Payees (external accounts) — verified beneficiary management with provider-side external account creation and per-payee provider routing.
FX & OTC — live currency-pair rates, quotes with locked execution, trade execution, and an OTC order desk with dual authorization.
Cards — card issuing (application, balance, PIN management, sensitive details) and card collections (payment intents, saved cards, tokenized charging, 3-D Secure).
Onramp / collections — fiat-to-crypto deposits by card or local payment methods, with settlement into Web3 wallets and multi-layer reconciliation.
Stablecoin payment links — hosted public payment pages (stables.gravv.xyz) for stablecoin collection.
Savings — yield-bearing balances via OpenTrade.
Billing — per-tenant fee configuration, fee charging with a state machine, subscriptions, and invoices.
Compliance — KYC / KYB onboarding via Sumsub, document management, transaction monitoring, and feature eligibility gating.
Tenancy Model
Gravv is multi-tenant. Each business customer is a tenant identified by a tenant ID that is propagated across every service call (as gRPC metadata). Tenants operate in one of two runtime environments — live or sandbox — selected per request by the API gateway, with separate credentials, connection pools, and secrets for each environment. Tenants manage team members with role-based permissions, API keys, IP whitelists, and webhook endpoints through the dashboard.
