IETF DNS-Based Payment Discovery

Authoritative specification in the x402 DNS Discovery IETF Draft eliminating centralized proxy registries via RFC 8461 MTA-STS pointer patterns.

Standard 01 // Discovery

Single-Roundtrip Resolution

Clients discover agent settlement endpoints in exactly 1 DNS lookup and 1 HTTPS GET, eliminating proprietary registration databases.

Standard 02 // IANA Allocation

Global _x402 Namespace

Registered permanent _x402 globally scoped DNS node identifier enabling native protocol discovery across any apex domain.

Standard 03 // Grammar

Section 4 ABNF Grammar

Strict deterministic key-value validation: v=x402-1, wk=https://..., k=facilitator, net=eip155:114, scheme=exact.

Confidential Silicon

Universal Silicon TEEs & Hardware Attestation

Sovereign execution environments where private keys, AI model weights, and agent state are protected inside hardware-encrypted silicon (Intel TDX, AMD SEV-SNP, NVIDIA GPU CC, AWS Nitro) with cryptographic quotes anchored to immutable ledger availability.

Silicon Security // Memory Isolation

Multi-Silicon Hardware Enclaves

Zero-trust infrastructure: even cloud hypervisors and root hosting administrators cannot read memory pages or extract signing keys from inside the running enclave.

Cryptographic Ledger // Blockchain DA

MRTD Hardware Hashes & Flare DA

Measurement Root of Trust hashes (MRTD) and hardware quote certificates are permanently posted to Flare Data Availability for instant on-chain verification.

Settlement Rails

Deterministic Canonical Settlement

Eliminating payload malleability via RFC 8785 JSON Canonicalization Scheme (JCS) and executing gasless payments across Flare Network and XRPL.

Rail 01 // Determinism

RFC 8785 Canonical JCS

24/24 test vector verification cross-checking float formatting, whitespace normalization, and UTF-16 code unit ordering across proxy meshes.

Rail 02 // Zero-Gas

EIP-3009 Gasless Payments

Facilitators execute transactions via receiveWithAuthorization where autonomous machine payers carry $0.00 in native gas balances.

Rail 03 // Multi-Chain

Cross-Ledger Atomic Clearing

Deterministic non-custodial clearing engine extending zero-gas settlement across EVM, XRPL, and institutional stablecoins with complete cryptographic proof verification.

Telemetry & Field Data

Global DNS Discovery Observatory

Ashlar Blue operates an automated worldwide telemetry crawler—the machine-trust equivalent of SSLLabs. The Observatory continuously audits apex domains to validate live IETF _x402 DNS discovery records, verify RFC 8785 canonical manifest signatures, and monitor hardware enclave attestation health across Flare Network and XRPL.

How To Get Started

Autonomous Agent Attestation & Settlement Lifecycle

Deploy and test machine settlement in three deterministic steps: discover payment metadata via DNS, verify multi-silicon hardware attestation, and execute zero-gas settlement across Flare Network and XRPL.

Discover Any Agent via DNS

Query the IANA registered _x402 DNS TXT record of any apex domain. Resolve payment terms, facilitator address, and hardware attestation manifests in a single roundtrip.

$ dig +short TXT _x402.domain.com
"v=x402-1; wk=https://...; k=facilitator"

Attest & Verify Silicon

Verify the server's hardware quote against the Flare Data Availability ledger. Guarantee counterparty code integrity without trusting cloud hypervisors.

ashlar.verifyTDXQuote(quoteBytes)
// MRTD Hash: 0x2e6bff01... [VERIFIED]

Settle with Zero Gas

Submit an EIP-3009 canonical authorization payload signed via RFC 8785 JCS. Ashlar Blue facilitators broadcast and settle atomically across Flare Network or XRPL.

ashlar.settleGaslessPayment(authPayload)
// Status: 200 OK (0.00 Native Gas Paid)

Frequently Asked Questions

Institutional & Technical FAQs

Key answers regarding protocol architecture, hardware enclave security, and corporate standing.

Ashlar Blue utilizes EIP-3009 (receiveWithAuthorization) and XRPL XLS-80 fee-sponsoring rails. Autonomous agents sign deterministic payment authorizations off-chain using their own private keys. Ashlar Blue facilitators submit the transaction and sponsor the native gas fee, deducting the exact micro-fee from the settled asset. The agent wallet requires $0.00 in native gas balances.

Standard software containers (Docker, Kubernetes) leave private signing keys and AI runtime memory accessible to cloud hypervisors and host administrators. Ashlar Blue requires hardware-enforced memory encryption across certified silicon—including Intel TDX (MKTME), AMD SEV-SNP (VCEK), and NVIDIA GPU CC on Hopper/Blackwell Tensor Cores. Cryptographic attestation quotes are generated directly in hardware and verified deterministically against immutable ledger data availability, guaranteeing mathematical proof of execution integrity.

Following the proven RFC 8461 (MTA-STS) pattern, services publish an unauthenticated DNS TXT record under the permanent IANA _x402 node (e.g. _x402.domain.com) pointing to an authenticated HTTPS manifest (/.well-known/x402). Clients resolve discovery in exactly 1 DNS lookup and 1 HTTPS GET, eliminating central directory bottlenecks.

No. Ashlar Blue is strictly non-custodial software and cryptographic infrastructure. We never hold, transmit, pool, or manage customer funds. All settlements occur atomically on decentralized ledgers (Flare Network and XRP Ledger) directly between counterparties.

Corrente Labs Inc. is the Delaware C-Corporation parent research laboratory governing the Ashlar Blue protocol. Corrente Labs architects the open IETF standards (x402 DNS Discovery & SCITT Receipts), engineers certified Intel TDX hardware attestation pipelines, and oversees institutional multi-chain cryptographic settlement rails.
