TREZOR SUITE API INTEGRATION
============================
Turning Self-Custody Wallet Data Into a Usable, Consented Data Feed
Trezor Suite is the companion app for Trezor hardware wallets, built by
SatoshiLabs in Prague and used worldwide to manage self-custody crypto
across Bitcoin, Ethereum, Solana, Cardano and thousands of tokens. Every
balance and transaction it shows is read straight from public blockchains
through an account descriptor (an xpub) — not from a private database
only the vendor controls.
That single fact is what makes Trezor Suite API integration possible.
Because the data lives on-chain, a consented xpub plus a blockchain
indexer (Blockbook) can reconstruct the exact same balances, transaction
history, UTXOs, token holdings and staking positions Suite itself
displays — without ever needing the physical device. Add the app's own
CSV/JSON export and its AES-encrypted labels file, and you get a
complete, human-readable picture: balances, history, account labels and
notes, normalized into one consistent schema.
This article walks through what is supported, where it fits, and why
this kind of crypto wallet protocol analysis is valuable for teams
building treasury tools, accounting pipelines or portfolio dashboards.

SUPPORTED API FEATURES
--------------------
• Consented xpub / descriptor reads via Blockbook-style indexing —
no hardware device required to view balances or history
• Full transaction history retrieval (id, time, amount, fee,
counterparties) with pagination support
• UTXO-level detail for Bitcoin-like chains: txid, vout, value,
confirmations
• Cross-chain token holdings (ERC-20, SPL) and staking position
tracking for Ethereum, Cardano and Solana
• Native CSV / JSON / PDF export parsing for one-off or scheduled
reconciliation pulls
• Encrypted label and note recovery from the app's metadata file,
merged back into normalized records
• A single normalized record shape across UTXO chains and
account-based chains — no per-coin branching downstream

USE CASES & APPLICATIONS
------------
[1] Treasury & Net-Worth Dashboards
• Aggregate balances and real-time fiat value across multiple
Trezor accounts and chains
• Feed a live portfolio view without ever touching the device
• Combine token holdings with native coin balances in one view
[2] Accounting & Tax Reporting
• Pull complete transaction history with fees and counterparties
for cost-basis calculations
• Use native CSV/JSON exports for monthly or quarterly
reconciliation
• Match on-chain transfers against accounting ledger entries
[3] Audit, Proof-of-Reserves & Compliance Checks
• Use UTXO-level data for coin control and reserve verification
• Maintain consent records and access logs for GDPR-aligned
minimization
• Cross-check balances against independent indexer queries
[4] Trade & Settlement Reconciliation
• Capture Buy/Sell/Swap order records routed through Invity's
partner providers
• Reconcile trade orders against matching on-chain settlements
• Track order status across MiCA-regulated trading flows
[5] Multi-Wallet & Cross-Platform Portfolio Tools
• Normalize Trezor Suite data alongside Ledger Live, OneKey,
Tangem, SafePal, ELLIPAL, ZenGo, Coldcard, NGRAVE and D'CENT
• Build a single schema covering UTXO and account-model chains
• Recover human-readable labels and notes across wallets for
unified reporting
------------
BENEFITS & ADVANTAGES
------------
✓ Durable integration path — built on public blockchain data
and an open indexer, not a shifting app UI
✓ No device dependency for read access — only a consented
descriptor is needed to view balances and history
✓ Privacy-aware by design — derivation gap limits and
self-hosted indexing keep the descriptor under your control
✓ One consistent record schema across UTXO and account-based
chains, simplifying downstream logic
✓ Encrypted label and note recovery adds human context to raw
on-chain transaction data
✓ Trade data reconciled against actual on-chain settlements for
accurate financial records
✓ Delivered as runnable source (Python/Node.js) with OpenAPI
spec, protocol report and automated tests — ready to integrate
------------
SUBSCRIPTION PLANS
------------
Two engagement models are available:
• Source delivery — starts at $300. Includes runnable code, an
OpenAPI/Swagger spec, a protocol and auth-flow report,
automated tests and interface documentation. Paid once the
integration is working in your hands.
• Metered hosted API — no upfront cost. Call the hosted
endpoints and pay per call if you'd rather not host the
integration yourself.
Typical build time runs one to two weeks depending on which accounts
and chains need to be reached.
Trezor Suite's self-custody model means the most reliable way to access
balances, transaction history, labels and trade data is not a typical
API key — it's a consented descriptor paired with public-chain
indexing, backed by the app's own export and metadata formats. That
combination produces a normalized, durable data feed that keeps working
across Suite's frequent releases.
For teams building treasury tools, accounting pipelines, audit systems
or multi-wallet portfolio platforms, this open data crypto integration
approach turns scattered on-chain and app-layer data into one
consistent, query-ready structure.
