The Problem

The Infrastructure Your Bank Was Never Built to Provide

African B2B trade moves fast. Traditional financial rails were not designed for it — and the cost is real: rejected payments, frozen accounts, and compliance gaps your regulator will find.

01 · De-risking

Your Account Closed Without Warning

Banks are withdrawing from cross-border corridors under international de-risking pressure. Importers operating on UAE, China, or Asia trade routes are disproportionately affected — often with no appeal process and no replacement.

02 · Compliance

No KYT Audit Trail — Regulatory Exposure

OKX, Binance — low fees (0.1–1 USDT), but zero KYT decisions in the audit trail. Received USDT through a CEX? You cannot explain the source to your regulator or a counterparty audit.

03 · Counterparty

Supplier Verification Is Your Problem

Your UAE supplier requires USDT, but without proof of source. You carry the compliance risk — instead of having infrastructure that handles it automatically.

04 · Audit

Zero Reproducibility Under Audit Review

Six months later your auditor asks why you approved that transaction. With a standard wallet, there is no reproducible decision record. With A2vanta, every decision is versioned.

Platform

Three Pillars of Institutional-Grade Treasury

Not a crypto wallet. Compliance infrastructure — built for regulatory scrutiny, auditor review, and counterparty verification on every B2B payment.

Pillar 01

KYT-First Compliance

  • Every inbound USDT screened through HAPI, Arkham, and GoPlus risk engines
  • Incoming fail-open with forced quarantine; outgoing fail-closed on blocked addresses
  • Zero automatic mixing of grey funds with operational wallet
  • One client = one dedicated deposit address — clean provenance by design
Pillar 02

Auditable Pricing

  • Fee = TRON network cost only: 6–7 TRX (activated) / 8–10 TRX (high-energy) / 13–14 TRX (new wallet)
  • Exchange rate snapshot (multi-source oracle) recorded in audit log — every figure reproducible
  • No percentage of amount, no caps — flat fee: 1M USDT costs the same as 100 USDT
  • Choose TRX or USDT payment; neither carries a hidden margin
Pillar 03

Multi-Sig Governance

  • 3-tier signing: treasury manager initiates, CFO approves, compliance reviews
  • Sponsor Energy Wallet isolated from operational wallet
  • AI agent has no access to Resource Manager — code-level guard
  • Every decision versioned and reproducible for any regulatory or auditor review
How It Works

KYT-first pipeline

Blocking decision short-circuits everything downstream. No accidental transactions, no automation over grey funds.

Inbound deposit → release
  1. Detect USDT TRC-20 transfer
    tx_hash, sender, amount
  2. KYT screen sender (HAPI + Arkham + GoPlus)
    risk_score, labels, decision
  3. Set DepositRiskStatus
    clean / review / quarantine / blocked
  4. Release after manual approval if not clean
    audit log per transition
Outbound request → broadcast
  1. KYT check destination address
    fail-closed if blocked
  2. Estimate Energy + recipient activation
    standard / high_energy / non_activated
  3. Quote fee (TRX / USDT, by oracle)
    client picks payment currency
  4. Multi-sig sign → broadcast
    tx_hash + audit record
Pricing

Transparent Pricing

TRON network cost — the only line item. OKX charges 0.1 USDT, Binance 1 USDT; neither provides a KYT decision in the audit trail. A2vanta does.

Fee Currency Choice

Pay in TRX or USDT — your choice before signing. If USDT — the fee is added on top of the transfer amount, not deducted from it.

Amount-independent

1,000,000 USDT costs exactly the same as 100 USDT. No percentage of volume, no caps.

Transparent Oracle

USDT rate — median of 4 sources (Binance, CoinGecko, CoinMarketCap, on-chain TWAP). Snapshot recorded in audit log at signing time.

Trust stack

No Black Box

Vendor stack is publicly declared, audit log is reproducible, signing tiers are architecturally separated.

KYT Vendors

HAPI · Arkham · GoPlus

Provider-agnostic adapter Phase 1. TRM Labs / Chainalysis — next stage after legal opinion and compliance budget.

Custody Recovery

AWS KMS + YubiKey FIDO2

Three custody models: non-custodial / assisted recovery / licensed. Choose based on your risk profile.

Signing Tiers

Admin · Super Admin · Compliance · AI

Each tier with RBAC scope. AI agent has no access to Resource Manager — code-level guard, audit, network ACL.

Audit Log

Reproducible 6+ Months Later

Every decision is versioned: engine_version + ruleset_hash. A compliance officer can always reproduce the logic.

FAQ

Frequently Asked Questions

Non-custodial: you hold the keys yourself. Assisted recovery: AWS KMS + YubiKey FIDO2 as backup path. Licensed custody: for regulated clients with external audit. Choose based on your risk profile.
In assisted recovery mode, recovery via AWS KMS shard + YubiKey FIDO2 second factor. Multi-sig topology: 3-of-5 for prod, 2-of-3 for test. One lost key does not block funds.
