Self-Custodial Wallet Data Access for Swap, On-Ramp, and Portfolio Layers
============================
INTRODUCTION
--------------------
Walletverse — distributed as Wallet Verse: DeFi, Buy Crypto — is a
self-custodial multi-chain DeFi wallet available on Android and iOS
(package com.walletverse). It supports 600+ cryptocurrencies and
blockchains, from Bitcoin and Ethereum to Solana, TRON, BNB, XRP,
Notcoin, and thousands of ERC20 and TRC20 tokens. Private keys never
leave the device, which changes the integration model in a fundamental
way: balance and transaction history are not locked behind the app at
all — they live on the public chains it derives addresses for and can
be reconstructed from the address set alone.
What earns its engineering budget is the layer above the keys: a
100+ DEX and CEX swap aggregator spanning 10,000+ trading pairs, six
aggregated fiat on-ramp providers (Moonpay, Simplex, Banxa, Transak,
Wert), portfolio and price-alert configuration, staking and yield
positions, NFT holdings, WalletConnect session state, and a quest
and fee-discount ledger that awards stars and NFT Hamster chests.
Those surfaces are server-side and account-bound — and that is where
this API integration service delivers value.
OpenBanking Studio maps, documents, and implements the authorized
interface layer so teams can pull swap quotes, on-ramp order state,
portfolio configuration, and quest data through a clean, testable
client — without reverse-engineering anything or bypassing consent.
============================
SUPPORTED API FEATURES
--------------------
The Walletverse integration covers every data domain the app exposes,
organized by origin and access method.
------------
On-Chain Balance and History Reconstruction
HD wallet derivation across Bitcoin, Ethereum, EVM L2s, Solana,
TRON and 600+ additional asset chains
Address-set derivation from extended public keys (xpubs) or
exported address lists — no dependency on the app being online
Per-address, per-token, per-chain balance reads via public chain
indexers and RPC endpoints
Full transaction history with timestamps, counterparties, and
token transfer details
Continuous re-derivation so newly created addresses are picked
up automatically, not silently missed
------------
Swap Aggregator Quote API
Access to the 100+ DEX and CEX aggregator (Uniswap, PancakeSwap,
1inch, Binance, Coinbase Pro and many more)
Per-pair, per-venue quotes with price impact and fee breakdowns
Best-execution selection with ranked alternatives
Short-lived quote handling: expired quoteIds trigger a fresh
request rather than serving stale rates
Contract-drift detection: automated tests flag when the quote
response shape changes
------------
Fiat On-Ramp Order and KYC State
Six aggregated on-ramp providers in a single normalized feed:
Moonpay, Simplex, Banxa, Transak, Wert
Per-order tracking with provider, fiat amount, crypto asset,
and KYC verification stage
FATF Travel Rule and identity handoff modeling per provider
KYC stage normalization so a pending verification step is not
misread as a failed purchase
------------
Portfolio, Alerts, Staking, and NFTs
Portfolio and price-alert configuration mirrored from server-side
account state
Staking and yield positions with per-validator or per-pool
accrued reward data
NFT holdings by collection and token ID, with on-chain metadata
WalletConnect and dApp session state for connection auditing
------------
Quest and Fee-Discount Ledger
Quest progress and star accrual from the in-app gamification layer
NFT Hamster chest awards and transaction fee discount tier state
Loyalty and fee-tier mirroring into external dashboards

============================
BENEFITS & ADVANTAGES
--------------------
No App Dependency for Balances
On-chain reconstruction from the address set works independently
of the Walletverse app being online or accessible at any moment.
600+ Chain Coverage in One Integration
Bitcoin, Ethereum, all major EVM L2s, Solana, TRON, BNB Chain,
and hundreds of additional networks under one normalized schema.
Single Feed Across Six On-Ramp Providers
Moonpay, Simplex, Banxa, Transak, Wert orders normalized into one
order schema with consistent KYC stage modeling across all six.
Contract-Drift Protection Included
Automated tests ship with the handover and flag changed quote,
on-ramp, or feed response shapes as failing tests — not silent
bad data reaching downstream consumers.
Delivery-First Pricing
Payment starts from $300 only after delivery and after you have
confirmed the integration works — or use the hosted pay-per-call
option with nothing upfront.
One to Two Week Build Cycle
Scoped builds against a consenting account or address material you
control, with runnable source, an OpenAPI spec, auth-flow report,
and data-retention guidance all included in the handover.
GDPR and Travel Rule Compliant Access
All access is authorized, documented, or user-consented. Personal
data such as portfolio config, alert rules, and device identifiers
is minimized and handled under GDPR. On-ramp order state is
modeled with FATF Travel Rule obligations per provider.
============================
SUBSCRIPTION PLANS
--------------------
Two engagement models are available for Walletverse API integration.
------------
Build and Deliver (From $300)
The complete integration — on-chain reconstruction module,
swap-quote client, on-ramp order feed, portfolio and quest
endpoints — is built and handed over as runnable source with
tests and documentation. Payment begins after delivery once
you have confirmed it works. Typical build cycle: one to two
weeks. Includes OpenAPI specification, protocol and auth-flow
report, contract-drift tests, and data-retention guidance.
------------
Hosted Pay-Per-Call
Skip the build entirely and call OpenBanking Studio's hosted
endpoints directly. No upfront cost, no infrastructure to run.
Priced per call, suitable for lower-volume needs or for teams
that want to evaluate the data before committing to a full build.
Both options start with a scoped conversation about the app and
the specific data domains needed — swap quotes, on-ramp orders,
on-chain balances, portfolio state, or the quest ledger.
============================
CONCLUSION
--------------------
Walletverse is one of the more complete self-custodial DeFi wallets
available today: 600+ chains, a 100+ venue swap aggregator, six
fiat on-ramp providers, staking, NFTs, WalletConnect, and an active
quest-based loyalty layer. The integration challenge is not the keys
— those stay on the device by design — but the server-side surfaces
above them: swap routing, on-ramp order state, portfolio config, and
the quest and fee-discount ledger that most teams initially overlook.
Getting that data into a clean, normalized, testable feed requires
mapping the authorized interface layer, normalizing six on-ramp
provider shapes into one order schema, handling short-lived swap
quotes correctly, and shipping contract-drift protection so the
integration holds up when the aggregator or feed contracts rotate.
That is exactly what this service delivers — on a fixed cycle, at
a price that only starts after you have confirmed it works.
