FTH Trading — Institutional Infrastructure Guide

🏛️ Platform at a Glance

FTH Trading is a full-stack institutional financial infrastructure platform. It is not a single product — it is an operating system for digital capital markets, built from the ground up to issue, settle, custody, distribute, and govern tokenized financial instruments across thirteen blockchains and five bank rail types, all under one unified compliance framework.

The platform is operated by FTH Trading Inc., a subsidiary of FutureTech Holding Company — a diversified holding enterprise founded in 2005 and headquartered in Atlanta, Georgia. For nearly two decades, FutureTech has invested in and operated businesses across technology, finance, and enterprise services. The platform implements AML, KYC, BSA, and MSB compliance programs and is structured to align with emerging U.S. federal stablecoin regulatory frameworks.

Key Principle

Every module declares not just what it does, but what it will never do. This is how FTH enforces operational boundaries at the code level, not just the policy level. The Module Registry is the single source of truth.

🔒 Three Hard-Boundary System Modes

The entire platform operates in three hard-boundary system modes, enforced by a component called SystemModeGuard. No module can cross these boundaries — this is enforced at runtime through code that blocks execution if a module attempts to operate outside its designated mode.

System Mode Architecture

Before any module function runs, SystemModeGuard performs three checks:

Does the current system mode match the module's registered modes?
Is the requested operation on the module's prohibited list?
Is the target chain in the module's registered chain set?

All three must pass or execution is rejected with a structured violation record that gets logged and flagged.

Mode	Scope	Prohibited Actions
INFRA	Anchoring, verification, proof systems, cross-chain ops	Must never match orders or issue securities
ISSUER	Bond series, coupon engines, capital structures	Must never verify third-party infrastructure
VENUE	Order matching, execution, surveillance	Must never issue securities or anchor proofs

⛓️ Thirteen Chains, Four Roles

FTH operates across thirteen blockchains, each with a defined role. Chains are organized into four functional groups — we do not scatter tokens randomly across networks.

Chain Role Architecture

Role	Chains	Finality	Purpose
Settlement	Stellar, Ethereum, Solana	3s — 15min	Money movement, USDC settlement
Anchor	Bitcoin, XRPL, Polygon	4s — 60min	Immutable proof, attestation
Governance	Cardano	~5min	On-chain governance actions
EVM	ETH, POLY, ARB, AVAX, BSC, BASE, OPT, TRON	Varies	Token deployment, collateral, coupons

Bitcoin Anchoring

Monthly OP_RETURN transactions write permanent, immutable proof into the most secure blockchain in existence. A Bitcoin OP_RETURN is there forever — it cannot be reversed or deleted. In ten years, anyone can verify the platform state hash recorded in that transaction.

⚡ Core Platform Capabilities

🗄️ VaultLedger

Append-only, cryptographically chained asset position ledger. Every asset movement is an immutable entry linked to the previous one. You cannot edit history — only append.

💳 Settlement Layer

StablecoinRail for multi-chain movement, PaymentIntent for deterministic lifecycle, SettlementRecorder logging across Stellar, Ethereum, and XRPL simultaneously.

📊 Bond Lifecycle

Seven states: Draft → Offered → Subscribing → Funded → Active → Maturing → Matured. BondRegistryXRPL anchors evidence using a linked-list chain pattern.

📈 Deterministic Order Book

Price-time priority matching. ExecutionLockManager prevents double-reservation. MarketSurveillance detects wash trading, spoofing, and front-running in real time.

🎯 FailureMatrix

Deterministic response for every possible failure mode. There is no undefined behavior — every failure has a defined response path.

💰 Distribution Engine

Scheduled payout distributions on Stellar — coupon payments, yield distributions, and redemption payouts automatically delivered to investor wallets.

🔁 ETF-Style Operations

CreationUnitPolicy and CreationRedemptionEngine handle creation/redemption units. AuthorizedParticipantRegistry manages KYC and permissions.

📡 Market Surveillance

Real-time detection of wash trading, spoofing, and front-running. MarketStressSimulator models extreme scenarios and failure cascades.

🏢 Corporate Structure & Governance

FTH Trading operates as a subsidiary of FutureTech Holding Company, a diversified holding enterprise founded in 2005. The holding company model emphasizes long-term ownership, disciplined capital allocation, and active operational oversight — not fund cycles or short-term exit mandates. The corporate structure is purpose-built for operational segregation and institutional-grade governance.

Entity	Code	Mandate	Role
FutureTech Holding Company	FTHOLD	Parent Holding Company	Enterprise oversight, capital allocation, since 2005
FTH Trading Inc.	FTHT	Digital Settlement Infrastructure	Primary operating subsidiary — all settlement and issuance
FTH Capital	FTHCAP	Capital Management	Structured products, yield operations, CPN-90 notes
FTH Custody	FTHCUS	Custody & Settlement	Segregated accounts, escrow, custody orchestration
FTH Treasury	FTHTRS	Reserve Management	Full reserve operations, collateral backstop, 1:1 backing

Operating History

FutureTech Holding Company has been investing in and operating businesses since 2005. Nearly two decades of active capital management, diversified enterprise operations, and long-term client relationships — not a startup, not a fund cycle, not a new entrant. This is institutional infrastructure built on twenty years of operating discipline.

👛 Wallet Architecture

Each operating entity has three designated operational sub-wallets, providing granular separation of fund flows:

🪙 Settlement Tokens Across Two Chains

The dual-chain token architecture divides assets between XRPL and Stellar based on each chain's strengths. Every token serves a defined settlement or reserve function — no speculative tokens, no governance experiments.

XRPL Tokens

Token	Purpose	Type
FTHUSD	Fully reserved digital dollar — 1:1 backed, redeemable at par	Digital Dollar
USDF	Digital dollar settlement token	Settlement
USD	Direct fiat settlement	Settlement
GBP	UK & international operations	Settlement
EUR	European markets	Settlement
GOLD	RWA-backed gold (999.9 fine)	Real-World Asset

Stellar Tokens

Token	Backing	Type
xUSD	1:1 USD stablecoin, wire-backed	Stablecoin
xEUR	1:1 EUR, SEPA-backed	Stablecoin
AURG	1 gram 999.9 fine gold at LBMA + 1.5%	Real-World Asset
xXRP	Cross-chain XRP bridge 1:1	Bridge
xGOLD	Gold synthetic tracking spot	Synthetic
xBTC	Bitcoin synthetic	Synthetic

🔐 Multi-Signature Security

The multi-signature configuration uses a 3-of-5 signer setup with five defined roles:

Role	Purpose	Storage
Primary	Daily operations	Secure device
Secondary	CFO approval	Separate secure device
Compliance	Compliance gate	Compliance officer
Recovery	Key recovery	Bank vault safe deposit box (2nd city)
Emergency	Emergency access	Legal escrow (different jurisdiction)

Security Guarantee

Three of five are required to move funds. Two signers cannot collude. One lost key does not lock the system. The recovery and emergency keys are stored in geographically separate, physically secure locations.

📋 The Module Registry

Every module in the FTH platform is registered in the Module Registry — the single source of truth. Each entry records:

Identity

Unique ID, name, description, and category assignment

Mode Permissions

Which system modes (INFRA/ISSUER/VENUE) the module may operate in

Chain Bindings

Which of the 13 blockchains the module interacts with

Risk Classification

LOW, MEDIUM, HIGH, or CRITICAL risk level

Prohibited Actions

Explicit "neverDoes" list — actions the module is forbidden from performing

Build Session

Which of the 16 sessions introduced this module

Runtime Enforcement

The neverDoes field is not documentation — it is enforced at runtime. For example, FundingMachine neverDoes: "Execute funding, Store credentials, Bypass arrival detection." If any code path violates these constraints, execution is blocked and a violation record is created.

🏦 The Custody Architecture

FTH does not hold client funds. This is not a policy statement — it is enforced by NoCustodyGuards, a module providing runtime assertions that the platform never takes internal custody.

Provider	Type	Role
Fireblocks	Primary MPC	Institutional-grade MPC custody, threshold signing, no single key
Anchorage Digital	Secondary MPC	OCC-chartered digital asset bank, qualified custodian
BitGo	Third MPC	Qualified custodian, combined custody + exchange

🔥 The Fireblocks Integration

The Fireblocks integration is one of the most sophisticated parts of the build. Six core modules were written from scratch:

Module	Function
FireblocksConfig	Singleton configuration loader for API credentials and endpoints
FireblocksJwt	RS256 JWT generation — every API call gets a fresh, short-lived token
FireblocksHttp	HTTP wrapper with auto JWT signing, retry with exponential backoff, error normalization
VaultTypes	Typed domain model for Fireblocks vault accounts
FireblocksVaultClient	CRUD operations via vault accounts API
FireblocksTransactionClient	Transaction submission and lifecycle tracking

🗄️ Twelve Vault Roles

Vault naming follows a deterministic convention: FTH-DEAL-ROLE-SEQUENCE. Twelve roles define every possible vault function:

Role	Purpose	Example
ISSUER	Bond issuer's primary vault	FTH-BOND01-ISSUER-001
COLLATERAL	Locked collateral positions	FTH-BOND01-COLLATERAL-001
COUPON	Coupon payment reserves	FTH-BOND01-COUPON-001
TREASURY	Operational treasury	FTH-BOND01-TREASURY-001
ESCROW	Third-party escrow holds	FTH-BOND01-ESCROW-001
HEDGE	Hedging strategy execution	FTH-BOND01-HEDGE-001
REDEMPTION	Bond redemption reserves	FTH-BOND01-REDEMPTION-001
OPERATIONS	Day-to-day operational movements	FTH-BOND01-OPERATIONS-001
RESERVE	Long-term reserves	FTH-BOND01-RESERVE-001
FUNDING	Incoming investor deposits	FTH-BOND01-FUNDING-001
SETTLEMENT	Outgoing settlement disbursements	FTH-BOND01-SETTLEMENT-001
FEE	Platform fee collection	FTH-BOND01-FEE-001

Idempotent Provisioning

FundingVaultProvisioner handles vault creation idempotently — calling it twice with the same parameters returns the existing vault rather than creating a duplicate. This prevents the vault proliferation problem that plagues most institutional custody setups.

⚡ EVM Execution Across Eight Chains

A complete EVM execution framework runs through Fireblocks MPC signing. No private key ever touches our servers.

EvmProviderFactory

EIP-1193 compatible providers backed by Fireblocks MPC across Ethereum, Polygon, Arbitrum, Avalanche, BSC, Base, Optimism, and Tron

BondTokenDeployer

Deploys ERC-20 and ERC-1400 security tokens on any of the 8 chains with transfer restrictions and compliance hooks

CollateralContractManager

WBTC and other collateral locking through a 10-state lifecycle from Unlocked to Released

CouponDistributor

On-chain coupon payouts — scheduled payments that execute automatically through smart contracts

🥇 Physical Gold Custody

The GOLD and AURG tokens are backed by physical 999.9 fine gold — not synthetics. Three partners handle the physical custody chain:

Partner	Role	Details
APMEX	Precious Metals Acquisition	Largest online PM dealer in US. Broker credit: Net 30/60/90. Bullion Club 5 tiers.
Citadel Global Depository	Secure Storage	APMEX subsidiary. Physical gold delivered here for storage.
Brink's Global Services USA	Physical Custody	Fully segregated vault storage. 55 bps annual storage fee.

Iron-Clad Invariant

AurumGramService enforces: circulating tokens × grams-per-token ≤ total reserve grams. Physical gold must be acquired, delivered, confirmed, and the reserve ledger updated before the mint function can be called. No fractional reserve. No pre-minting. If audit receipt is stale (>90 days), minting is automatically blocked.

📊 Ten Exchange Connections

Tier	Providers	Purpose
Tier 1 — Institutional	Coinbase Prime, Kraken, Binance US, Bitstamp, Gemini	Standard exchange ops — orders, execution, settlement
Tier 2 — Custody+Exchange	BitGo, Anchorage	Trade directly from custodied positions, no transfer needed
Tier 3 — OTC Desks	Galaxy Trading, Wintermute, Cumberland	Large block trades without market impact

Treasury Guards

$10M maximum per single transfer. $50M maximum daily aggregate. Every movement requires one of 10 defined reason codes: Hedge Funding, Collateral Lock, Coupon Liquidity, Rebalance, Liquidation Prep, Fee Payment, Yield Harvesting, Settlement, Redemption Funding, or Reserve Management.

🏛️ Partner Banks & Settlement Rails

Bank	Rail Type	Settlement Time
Synapse	ACH + Domestic Wire	4–24 hours
Column Bank	FedWire (direct Federal Reserve)	~2 hours
Cross River Bank	Cross-border + SWIFT	24–48 hours

Rail	Region	Settlement Window
ACH	US Domestic	24 hours
Domestic Wire	US Domestic	~4 hours
FedWire	US Domestic (urgent)	~2 hours
SWIFT	International	48 hours
SEPA	European	24 hours

🚀 Six Onramp Partners

Six fiat-to-crypto onramp partners provide global coverage. The FundingRoutePlanner automatically selects the optimal provider based on asset, fees, settlement time, and reliability.

Partner	Type	Coverage	Best For
Onramper	Meta-Aggregator	100+ payment methods worldwide	Global routing — auto-selects best underlying provider
MoonPay	Direct Converter	Card + bank transfer	Widget checkout, embedded flows
Transak	Widget Converter	100+ countries, local payments	Regional payment methods, HMAC-SHA-256 webhooks
Circle Mint	Institutional	Bank wire → native USDC	Institutional investors — wire in, USDC out, vault secured
Stripe	Traditional	Card + bank payments	Crypto onramp checkout sessions
Coinbase Commerce	Crypto-Native	USDC, USDT, DAI	Investors who already hold crypto

🎯 The Funding Orchestrator

The FundingOrchestrator is the single entry point for all funding operations. Every deposit, regardless of source, flows through it.

Event Types

Fail-Closed Safety

If no real provider is configured, the NullFundingProvider serves as a fail-closed safety default that rejects all operations. The system will never silently fail to process a deposit or accidentally route funds to a misconfigured provider.

🔍 Multi-Chain Deposit Detection

The DepositArrivalDetector monitors nine chains simultaneously. Each chain uses its native detection mechanism:

Chain Type	Detection Method	Chains
EVM	Transfer event logs from smart contracts	Ethereum, Polygon, Arbitrum, Avalanche, BSC, Base, Optimism
XRPL	Ledger subscription streams (real-time)	XRPL
Solana	Account change notifications (websocket)	Solana
Bitcoin	UTXO scanning	Bitcoin
Bank Rails	Wire reference number correlation	ACH, Wire, SWIFT

Webhook Fallback

If webhook delivery fails, FundingPollingFallback activates automatic status polling with exponential backoff: 30s → 2min → 5min. No deposit goes undetected even if real-time channels fail.

💎 Multi-Chain Stablecoin Architecture

Seven stablecoins across up to five chains each — this is what makes the scaling story real.

Stablecoin	Chains	Issuer
USDC	Ethereum, Arbitrum, Base, Solana, XRPL	Circle
USDT	Ethereum, Tron, Arbitrum, Solana	Tether
DAI	Ethereum, Arbitrum, Optimism, Polygon	MakerDAO
PYUSD	Ethereum, Solana	PayPal / Paxos
RLUSD	XRPL, Ethereum	Ripple
XRP	XRPL (native)	Ripple
XLM	Stellar (native)	SDF

Cross-Chain Bridge Pairs (XRPL ↔ Stellar)

Pair	Fee	Range
XRP → xXRP	0.25%	10K — 100K
AURG → AURG	0.50%	1 — 50K
xGOLD → xGOLD	0.50%	1 — 10K

The LienPolicyEngine defines waterfall claim priority: Senior → Mezzanine → Junior. The waterfall is computed deterministically — no discretion, no manual overrides. The EscrowWorkflowEngine manages the escrow lifecycle — depositing collateral, computing coverage ratios, monitoring price feeds, issuing margin calls, and triggering liquidation.

🎯 Failure Matrix — No Undefined Behavior

The FailureMatrix provides a deterministic response for every possible failure mode. There is no undefined behavior in the platform — every failure has a defined, documented, and tested response path.

Design Principle

The FailureMatrix is not an error handler — it is a decision engine. For every failure class (network, custody, compliance, settlement, market), there is a prescribed recovery action, escalation path, and fallback behavior. No failure goes unhandled. No error produces undefined state.

Network Failures

Chain-specific retry with exponential backoff, automatic failover to alternative settlement rails

Custody Failures

CustodyRegistry health tracking, automatic routing to secondary providers, operation queuing

Compliance Failures

Hard blocks on compliance violations — no bypass, no override, full audit trail

Market Stress

MarketStressSimulator models extreme scenarios and cascading failures before they happen
