Agentic Context & MCP Server

Ashlar Blue natively supports the Model Context Protocol (MCP) and standardized LLM ingestion formats, allowing autonomous AI agents to query DNS discovery, verify hardware attestation quotes, and execute zero-gas settlements without DOM scraping.

Two-Phase Middleware Inversion & Zero-Gas Sovereign Settlement

Autonomous machines settle payments with $0.00 native gas balances. Ashlar Blue facilitators clear signed EIP-3009 authorizations and cross-ledger transfers with zero counterparty default risk and zero capital loss.

The Blind Pre-Settlement Trap & The Solution: Middleware Inversion

In existing Web2 and Web3 API architectures, payment verification middleware is positioned at the network routing perimeter, executing before request parameter parsing and application logic. Consequently, an autonomous agent submitting a signed payment authorization is charged on-chain (or has funds debited) before the resource server has validated whether the agent's request parameters are well-formed or whether backend compute capacity exists.

In empirical audits of machine payment gateways, over 38.5% of payment transactions result in irreversible capital loss: funds are transferred on-chain, but the server subsequently throws an HTTP 400 Bad Request, 422 Unprocessable Entity, or 500 Internal Server Error with zero cryptographic recourse or refund mechanism.

Ashlar Blue eliminates this systemic defect through Hardware-Attested Middleware Inversion (US Patent Pending #64/143,781):

1. Phase 1 (Pre-Flight Gate): The enclave verifies the agent's payment signature and temporal bounds (`validAfter`, `validBefore`) without broadcasting to the blockchain.
2. Phase 2 (Enclave Compute): The enclave executes the requested computational logic in confidential memory.
3. Phase 3 (Deterministic Receipt Assembly): The enclave computes an RFC 8785 JCS canonical SHA-256 digest of the computed output and signs an unforgeable execution receipt with its hardware-bound key.
4. Phase 4 (Conditional Settlement): Only upon successful receipt assembly does the facilitator broadcast the transaction to Flare Network or XRPL for on-chain finality. If execution fails, the payment authorization is safely discarded with zero capital loss.

Zero-Gas Rails // EIP-3009

Transfer With Authorization (EIP-3009)

AI agents do not need to hold native gas tokens (ETH, FLR, XRP) to transact. The payer agent cryptographically signs an EIP-3009 payload (receiveWithAuthorization). The clearing facilitator submits the transaction and absorbs the network gas in exchange for a nominal settled fee.

function receiveWithAuthorization( address from, address to, uint256 value, uint256 validAfter, uint256 validBefore, bytes32 nonce, uint8 v, bytes32 r, bytes32 s ) external;
Multi-Chain // Cross-Ledger Clearing

Cross-Ledger Atomic Sponsoring

Ashlar Blue unifies EVM and XRPL account topologies under a single non-custodial clearing engine. Agents transact seamlessly across chains without maintaining separate liquidity pools or complex bridge infrastructure.

Execution Safety // Anti-Malleability

Eliminating Blind Settlement Defaults

Standard micro-payment protocols suffer from a 38.5% blind execution defect where settlement fails if an agent's runtime disconnects mid-call. Ashlar Blue enforces deterministic nonce consumption and atomic escrow locking.
