Diamond Standard Architecture

T3Token uses the Diamond Standard (EIP-2535) for modular, upgradeable smart contracts.

Diamond Pattern Benefits

The Diamond Standard allows unlimited contract size by splitting functionality across multiple facets. Each facet can be added, removed, or upgraded independently without losing state or breaking existing integrations.

Core Components

Component	Purpose	Size
`Diamond.sol`	Main proxy contract that delegates calls to facets	~2KB
`DiamondCutFacet.sol`	Handles adding/removing/replacing facets	~3KB
`DiamondLoupeFacet.sol`	Provides introspection capabilities	~1.5KB
`T3TokenTransferFacet.sol`	Advanced transfer logic (largest facet)	~6KB

SecureSettle: Crypto-to-Fiat Bridge

SecureSettle is a universal crypto-to-fiat settlement bridge that eliminates settlement risk through a decentralized, automated escrow service.

✅ New Feature - December 2024

Core Innovation: SecureSettle bridges crypto assets with traditional fiat systems using secure on-chain escrow and off-chain oracle confirmation. It supports multi-asset settlement, self-custody vaults, and features a novel custodial reversal system to mitigate settlement risk while protecting consumers.

Architecture Overview

SecureSettle integrates with the existing T3 Diamond architecture as a dedicated facet, interacting with external oracles and the Cubix network to confirm fiat settlement before releasing on-chain assets.

Core Data Structures

struct SecureSettleData {
    address cryptoAsset;           // BTC.b, ETH, T3USD, etc.
    uint256 cryptoAmount;
    string fiatCurrency;           // USD, EUR, etc.
    uint256 fiatAmount;
    bytes32 cubixTransactionId;    // External settlement reference
    bytes32 clearingEndpointHash;  // Dynamic clearing endpoint security
    uint8 settlementMode;          // 0=custodial, 1=self-custody
    address breakGlassCustodian;   // Emergency recovery address
    uint256 oracleConfirmationAt;  // Fiat settlement timestamp
}

struct CustodialReversal {
    address originalSender;        // User who initiated reversal
    uint256 amount;                // Amount being held
    bytes32 relatedSettlementId;   // Associated SecureSettle transaction
    uint256 autoReleaseTime;       // When auto-release becomes available
    bool isReleased;               // Whether funds have been released
}
                

Standard Crypto-to-Fiat Workflow

Escrow Creation: A user calls createSecureSettle(), depositing a crypto asset and providing a hash of a secret clearing endpoint.
Fiat Processing: An off-chain fiat transfer is initiated. The Cubix network (or other rail) confirms fiat delivery.
Oracle Confirmation: A trusted oracle receives proof of fiat settlement and calls confirmFiatSettlement() on-chain.
Asset Release: The oracle reveals the secret clearing endpoint. The contract verifies the hash and releases the escrowed crypto asset to the recipient.

WRITE createSecureSettle ~180k gas

function createSecureSettle(
    address cryptoAsset,
    uint256 cryptoAmount,
    string calldata fiatCurrency,
    uint256 fiatAmount,
    bytes32 clearingEndpointHash
) external payable returns (bytes32 settlementId);
                        

Creates a new secure settlement escrow, locking the specified crypto asset.

Dynamic Clearing Endpoint

The clearingEndpointHash is a keccak256 hash of a unique URL, a nonce, and a user-supplied secret. This commit-reveal pattern prevents replay and misrouting attacks, ensuring each settlement confirmation is unique.

WRITE confirmFiatSettlement ~150k gas

function confirmFiatSettlement(
    bytes32 settlementId,
    string calldata clearingURL,
    bytes32 nonce,
    bytes32 userSecret,
    bytes32 cubixTransactionId
) external;
                        

Called by a trusted oracle to confirm fiat settlement and release the escrowed assets.

Access Control:

Requires SETTLEMENT_ORACLE_ROLE.

"Custody-less" Self-Custody Vault

SecureSettle can also function as a personal time-locked vault with an optional institutional recovery mechanism, allowing for secure self-custody.

WRITE createSelfEscrow ~120k gas

function createSelfEscrow(
    address cryptoAsset,
    uint256 amount,
    bytes32 secretHash,
    uint256 releaseTime,
    address breakGlassCustodian
) external payable returns (bytes32 escrowId);
                        

Locks an asset in a self-custody vault. The asset can only be released by revealing the secret, by the owner after the release time, or by the designated custodian.

Parameter	Type	Description
`secretHash`	bytes32	A hash of a secret only the owner knows.
`releaseTime`	uint256	A future timestamp when the owner can release funds without the secret.
`breakGlassCustodian`	address	An authorized institution that can recover funds in an emergency.

WRITE custodianRecover ~70k gas

function custodianRecover(bytes32 escrowId) external;

Allows a designated custodian to execute a "break-glass" recovery, returning the funds to the original owner's wallet.

Access Control:

Caller must be the breakGlassCustodian for the specified escrow and have the CUSTODIAN_ROLE.

Institutional-Grade Recovery

This feature provides a powerful safety net, blending the benefits of self-custody with the security of institutional oversight. All recovery actions emit a CustodianRecovery event for a full audit trail.

Settlement Risk Mitigation

To prevent a bad actor from abusing T3's reversible transaction feature to steal funds after a fiat settlement, reversals related to recent SecureSettle activity are routed to a custodial wallet for review instead of being returned to the sender.

Resolution Pathway	Scenario	Outcome
Auto-Release	Settlement expires without fiat confirmation.	Funds are automatically returned to the original sender after a buffer period.
Custodian Resolution	A complex dispute arises (e.g., oracle failure).	A custodian with `CUSTODIAN_ROLE` investigates and sends funds to the correct party.
Multi-Sig Emergency	A high-value or legally complex dispute.	Multiple admins must approve the resolution.

Facet	Purpose	Key Roles
`CambioEscrowFacet`	Creates/cancels note escrows, exposes note metadata.	`CAMBIO_ISSUER_ROLE`
`CambioRedemptionFacet`	Burns notes, releases funds, tracks receipts, enforces nonce replay protection.	`CAMBIO_REDEEMER_ROLE` or issuer.
`CambioAdminFacet`	Configures caps, metadata limits, and pause state for the analog channel.	`CAMBIO_ADMIN_ROLE`

Storage Append (AppStorage v4)

struct CambioNote {
    address issuer;
    address cambio;
    uint256 escrowedAmount;
    uint256 spent;
    uint48 createdAt;
    uint48 deadline;
    bool active;
    bytes32 phraseHash; // Non-zero when a recovery phrase is required for redemption
    uint16 phraseLength;
    bytes16 phraseChecksum; // Entropy used to derive 5-character checksum code
}

struct CambioReceipt {
    bytes32 noteId;
    address issuer;
    address redeemer;
    uint256 amount;
    uint48 timestamp;
    bytes32 metadataHash;
}

struct CambioConfig {
    bool cambioPaused;
    uint256 maxNoteValue;
    uint48 minDeadlineBuffer;
    uint48 maxDeadlineWindow;
    uint32 maxMetadataLength;
}
                

Lifecycle Flow

Issue: Cambio calls createCambioNote or createCambioNoteWithPhrase. Both lock funds into the diamond; the latter returns (bytes32 noteId, string checksumCode) so issuers can print the note with its 5-character checksum.
Redeem: Redeemer invokes redeemCambioNote (QR/ID path) or redeemCambioNoteWithPhrase. Phrase-protected notes enforce length checks and a keccak256 match before funds are released.
Settle: Merchants transact using HalfLife-enabled transfers; reversals remain available until commitWindowEnd lapses.
Cancel: Issuer may cancel unused notes to reclaim escrowed balances.

Phrase Enforcement

CambioPhraseTooShort, CambioPhraseTooLong, CambioPhraseRequired, and CambioPhraseMismatch provide deterministic guardrails for handwritten phrases. The 5-character checksum is derived from stored entropy so offline handoffs can be verified quickly while redemption still requires the full keccak256 match.

Testing & Observability

Unit: Bounds, duplicate IDs, metadata size, nonce replay, administrative controls.
Unit (Phrase): Recovery phrase issuance and redemption tests ensure minimum/maximum length, mismatch reverts, and successful flows.
Integration: CambioHalfLifeIntegration couples redemption with HalfLife reversals/expiry.
Golden Path: End-to-end regression now exercises issuance → redemption → reversal → continued redemption.

Role Separation

Ensure Cambio roles are granted explicitly. Issuers, redeemers, and admins operate independently to prevent overreach. Set maxNoteValue and minDeadlineBuffer to align with jurisdictional risk tolerances.

Investment Platform Facets — removed in v1.0.0

This subsystem is not part of the framework and is not deployed. An investment platform — vehicle registry, governance, compliance, yield and revenue distribution — was built out substantially (roughly 12,000 lines including test suites) and then removed before the v1.0.0 release because the distribution mechanism did not work correctly.

The specific defects, recorded at the time of removal:

YieldDistributionFacet was event-only — it emitted distribution events but no tokens ever actually moved. Tax-withholding routing was never completed.
RevenueDistributionFacet relied on a placeholder wallet-to-bank routing function, which broke revenue attribution.
DistributionManagementFacet used an accounting model that did not align with the canonical bank-deposit issuance model (ADR-001 claim buckets).
InvestmentVehicleRegistryFacet and InvestmentComplianceFacet had enum drift against their interfaces and placeholder statistics functions that reverted.

Shipping a distribution system that reports success while moving no money is worse than shipping nothing, so the code was removed rather than carried forward disabled. Reviving it is tracked as a backlog item with the per-facet fixes required; the implementation is preserved in the development repository's history.

Hash commitments and post-quantum posture

SmartLock envelopes release escrow against a hash commitment rather than a signature. At creation the sender stores hashCommitment = keccak256(fragment || nonce); release requires revealing a preimage that re-derives it. The full secret is never committed on-chain — only a per-transfer fragment and nonce — so recovering a lock means finding a preimage, not breaking a signature.

That distinction matters for quantum exposure. Shor's algorithm breaks ECDSA outright, which is what a signature-gated lock would depend on. Grover's algorithm gives only a quadratic speedup against preimage search, and against a 256-bit commitment that leaves roughly a 2¹²⁸ effective margin — already impractical, and further constrained because a lock's commitWindowEnd bounds the attack to the lifetime of that single transfer rather than a long-lived key.

This is a design posture, not a post-quantum implementation. T3 uses no lattice-, hash-, or code-based PQC signature scheme, and the surrounding system still relies on ECDSA for transaction authorisation and ERC-2771 meta-transactions — so an adversary with a cryptographically relevant quantum computer would attack those, not the SmartLock commitment.

The claim is narrow and deliberate: the lock-release path does not add ECDSA exposure. It is not a claim that the system is quantum-resistant.

What happened to the earlier design

A predecessor facet, LockedTransferManagerFacet, carried explicit quantum-threat-level plumbing — threat-level events, an emergency response path, and a multi-method fragment derivation scheme. That machinery was not carried forward into the envelope model. The facet now lives under archive/legacy-facets/; it is not in the active manifest and is not deployed. What survived into SmartLockEnvelopeFacet is the commitment scheme itself.

Earlier versions of this page described that archived design in the present tense and characterised it as a breakthrough in quantum-resistant cryptography. It was neither current nor a breakthrough, and the wording above replaces it.

AccessControlFacet.sol

Role-based access control system with hierarchical permissions.

Role Hierarchy

Role	Permissions	Admin Role
`DEFAULT_ADMIN_ROLE`	Full system control, diamond cuts	Self-administered
`ADMIN_ROLE`	Parameter updates, emergency functions	DEFAULT_ADMIN_ROLE
`MINTER_ROLE`	Token minting and burning	ADMIN_ROLE
`PAUSER_ROLE`	Emergency pause/unpause	ADMIN_ROLE
`CUSTODIAN_ROLE`	KYC/AML management	ADMIN_ROLE

WRITE grantRole ~45k gas O(1)

function grantRole(bytes32 role, address account) external returns (bool);

Grant role to account. Caller must have admin role for the target role.

Atomic Emergency Coordination System

Sub-second response system for critical situations with automatic fallback mechanisms.

Emergency Response Capabilities

The emergency coordination system provides atomic responses to critical situations including quantum threats, regulatory compliance issues, and security incidents. Response time typically under 200ms with automatic fallback to safe states.

Emergency Response Hierarchy

Threat Level	Response	Authority Required
Level 1-3 (Low)	Enhanced monitoring, parameter adjustment	ADMIN_ROLE
Level 4-6 (Medium)	Partial pause, compliance verification	PAUSER_ROLE
Level 7-8 (High)	Full pause, emergency transfers	DEFAULT_ADMIN_ROLE
Level 9-10 (Critical)	System lockdown, emergency coordination	Multi-signature required

Quantum Threat Response

The system includes quantum-safe fallback mechanisms. In case of quantum cryptographic threats, the system can automatically switch to post-quantum cryptographic standards and suspend vulnerable operations.

Admin UI + Data Explorer

Not part of the v1.0.0 public release. ui-management/ exists in the development repository but was held back as not yet release-caliber, so it is not in the published snapshot and the commands below will not work against a fresh clone. Reinstating it is tracked as issue #1 (~1.5–2.5 days of work). The indexer/ it reads from does ship, so the Ponder half of this page is usable today. This section describes the intended operator surface.

Operations teams use the Admin UI to manage permissions, treasury controls, compliance workflows, and consortium governance without touching the CLI. The Data Explorer sits on top of the Ponder indexer and offers both natural-language prompts and raw GraphQL queries for audits, investigations, and executive reporting.

What the UI Covers

Admin: role assignment, treasury parameters, and guardrails.
Banking: minting, transfers, and fee configuration.
Compliance: monitoring, activity review, and rules management.
Consortium: member onboarding, institution lifecycle, and coordination.
Financial: interbank liabilities and settlement oversight.

Data Explorer Workflows

Natural-language questions for non-technical users.
GraphQL mode for analysts and auditors.
Batch HalfLife summary view that groups batch events with per-recipient records.
Quick access to Cambio, envelope, compliance and rules activity. (Earlier drafts also listed SecureSettle and multi-sig settlement; both facets were superseded and now live under archive/legacy-facets/ — they are not in the active manifest and are not deployed.)

Run Locally

The indexer step works against the public repository. The ui-management step requires the development repository until issue #1 lands.

cd indexer
npm run dev

cd ui-management
npm run dev

Configuration

Set NEXT_PUBLIC_PONDER_URL (defaults to http://localhost:42070/).
Ponder serves GraphQL at the root path (/) and expects POST requests.

Ongoing Enhancements

Expanded query presets and natural-language coverage as new facets ship.
Richer compliance dashboards for audit, incident, and rules workflows.
Improved data exploration with new summary views and exportable tables.

Batch HalfLife Semantics

Batch HalfLife events use an indexed address[] recipients parameter, so logs emit a hash rather than the full list. The indexer records:

recipientsHash for batch events
Per-recipient events via HalfLifeExpiredSingle and HalfLifeReversedSingle

{
  batchHalfLifeEvents {
    items {
      eventType
      recipient
      amount
      totalProcessed
      totalAmount
      recipientsHash
      txHash
      timestamp
    }
  }
}
