Developer Experience

Facet boundaries keep storage layouts consistent while enabling rapid iteration on new compliance rules, fee models, or currency extensions.

Gas-aware Optimized selectors and relay flows keep costs predictable, even with policy enforcement.

Governance & Safety

Access control libraries, paused states, and emergency coordination facets orchestrate safe rollbacks without halting the entire ecosystem.

Atomic coordination Coordinated pause and resume across Cambio, HalfLife, and relay layers prevent fragmented state.

HalfLife Reversible Transactions

A programmable settlement window lets authorized actors undo mistakes without removing finality for good actors.

Dynamic HalfLife Windows

Configurable per asset, per role, or per transaction type.

5m - 72h
Typical policy bands

Key Mechanics

  • Transfers emit policy metadata for analytics and audit review.
  • Authorized roles can escalate to SmartLock if additional investigation is required.
  • Once a HalfLife expires, the funds become irreversible and release Protect accruals.

SmartLock Emergency Controls

Freeze, unfreeze, and coordinate across systems.

Governed Authority

  • Role-based access ensures only designated responders can initiate locks.
  • Lock states propagate to Cambio, relayers, and off-chain services via events.
  • Audit logs capture the reasoning and approvals for every action.

T3 Protect Insurance & Fee Rails

Programmable economics keep the ecosystem solvent and align incentives.

Protect Accrual Engine

Fees accumulate to cover future losses and reimburse customers.

Capabilities

  • Streamed fee accruals per transfer, adjustable by policy.
  • Transparent balance reporting with claims tracking.
  • Integrates with external reinsurers via event hooks.

Rules Engine & Analytics

Compliance automation without sacrificing developer velocity.

Controls

  • Allow/deny lists, velocity limits, and scenario-based policies.
  • Event streaming to SIEM, case management, and regulatory reporting tools.
  • Configurable callbacks for KYC/AML checks before settlement.

Gasless Relay & Integration Tooling

Deliver a Web2-smooth experience with enterprise-grade observability.

Meta-Transactions

EIP-2771 compatible flows hide gas from end users.

Highlights

  • Relayer service signs and forwards user intents with policy enforcement.
  • Replay protection and nonce management hardened through tests.
  • UX surfaces clear status updates with webhook callbacks.

Developer Tooling

Storage layout reports, selector maps, and coverage dashboards.

Toolchain

  • Hardhat tasks for deployment, upgrades, and verification.
  • Automated coverage, gas reporting, and storage layout diffs.
  • Documentation links to white paper, policy drafts, and integration samples.
