For Builders

The first programmable compliance primitive in production.

Build against PG[Σ] policy-gated threshold signing, the Agent Mesh, L3RS-1, and a chain-agnostic, AI-enhanced liquidity router. Six agent classes, fourteen named AI capabilities, eight chains at launch.

L3RS-1 v1.0.0 Profile F

The asset standard with a total ComplianceModule.

L3RS-1 is the token standard that ships compliance as a first-class field, not an afterthought. Profile F is the institutional profile: jurisdiction-bound, identity-tier-bound, Travel-Rule-bound, audit-ready. Every L3RS-1 Profile F token carries a canonical PolicyHash that gets bound into every signature that moves it.

The standard is open. The reference implementation is in TypeScript, with Rust and Python ports landing alongside the public reproducibility harness in Q3 2026. The full specification — including the formal definition of the ComplianceModule, the canonical hashing scheme, the transfer semantics, and the audit-trail format — lives in Crypto Spec §3 through §5.

example.ts

import { L3RS1, ComplianceModule } from "@t3rra/sdk";

const policy = ComplianceModule.create({
  jurisdiction: ["EU", "UK"],
  identityTier: "qualified-investor",
  travelRule: true,
  lockup: { duration: "12mo", from: "mint" },
});

const token = await L3RS1.mint({
  asset: "PrivateCreditBook-2026-Q2",
  policy,
  totalSupply: 50_000_000n,
});

console.log(token.policyHash);
// 0x7b3c...e4f1

Flow

AI-enhanced, chain-agnostic liquidity router.

Section 15 of the Flow paper is twenty-six pages. Architecture, ablation, and failure modes — all published. Section 16 covers cross-chain sourcing.

Residual GBM route scorer

Scores candidate routes against PHI residuals. Trained on 18 months of synthetic and shadow-traffic data. Beats a hand-tuned heuristic by 23% on the public benchmark.

Learned re-ranker

Real-time pairwise re-ranking under venue conditions. Sub-millisecond inference. Falls back to the rule-based ranker on anomaly flag.

LLM quote evaluator

Reads RFQ quotes for hidden adverse terms under structured prompting. Catches 9 of the 11 adverse-term classes in the test set.

LSTM inventory forecaster

Predicts depth and inventory across chains on a 5–60 minute horizon. Used by the settlement timing optimizer.

Deep anomaly detector

Autoencoder over the joint route/venue/quote distribution. Flags outliers for human review without blocking flow.

Cross-chain routing

Chain-indexed venue graph, (5,9) bridge committee, certificate-bound atomic settlement. The reason an L3RS-1 asset can roam.

The Agent Mesh

Six agent classes. Fully addressable.

Every action passes through the same PG[Σ] envelope. Agents and humans are protocol-indistinguishable.

Reference Code

Verify a PolicyHash in three lines.

verify-policy.ts

import { verifyPolicyHash } from "@t3rra/sdk";

const ok = await verifyPolicyHash(transcript, policyDoc);
if (!ok) throw new Error("Policy violation: signature does not bind PolicyHash");

SDK in TypeScript at launch. Rust and Python ports alongside the public reproducibility harness in Q3 2026.

Verify a route certificate.

verify-route.ts

import { verifyRouteCertificate } from "@t3rra/sdk";

const cert = await flow.routeCertificate(routeId);
const ok = verifyRouteCertificate(cert, {
  predicate: "J ∧ T ∧ ID ∧ X",
  chains: ["ethereum", "base", "stellar"],
});

The route certificate is a verifiable proof that the admissibility predicate held along every hop. Three lines, no trust assumption.

Verify a cross-chain certificate.

verify-crosschain.ts

import { verifyCrossChainCertificate } from "@t3rra/sdk";

const ok = await verifyCrossChainCertificate(cert, {
  committeeThreshold: { n: 9, t: 5 },
  asset: token.id,
});

(5,9) committee. Stated unforgeability theorem. Atomic under partial network failure. Crypto Spec §10–§11.

What We Publish

Reference SDK

TypeScript at launch. Rust and Python in Q3 2026. Open-source under Apache-2.0.

FAQ

Common questions.

Which chains are supported?

Eight chains at launch: Ethereum, Base, Arbitrum, Polygon, Avalanche, Solana, Stellar, and Polkadot. The same L3RS-1 asset can exist on any or all of them under one compliance envelope.

Is the SDK open source?

The reference SDK is open-source under Apache-2.0. TypeScript at launch, with Rust and Python ports in Q3 2026.

What is the upgrade path for existing tokens?

L3RS-1 Profile F is designed to wrap or interoperate with existing permissioned token standards like ERC-3643. Migration paths depend on the source standard — contact dev@t3rra.co for guidance.

What is the audit status?

Two independent Tier-1 audits are required before any L3RS-1 issuance goes live. Audit reports are published alongside the issuance documentation.

The primitive is published. The SDK is shipping. Build something we will be proud to settle.
