The first fully sovereign, self-governing, Scudo-native DeFi treasury agent that pays for its own intelligence, enforces cryptographic multi-agent governance, and preserves capital with verifiable intent under Tether’s official unit of account.
XAU₮Anchor is a fully autonomous DeFi treasury agent that dynamically manages a three-asset portfolio — USDT, XAU₮ (Tether Gold), and Aave V3 aUSDT — with zero human input, executing on a 5-minute reasoning loop with a full on-chain audit trail.
Core Thesis: Gold and crypto are anti-correlated in fear markets. XAU₮ is Tether's own gold-backed token. XAU₮Anchor is the first autonomous agent built specifically around Tether's dual-asset vision to preserve capital during periods of high volatility.
XAU₮Anchor executes tasks autonomously, manages capital, and interacts with on-chain logic (WDK-native Aave V3 lending, x402 micropayments) under strictly defined constraints. Builders defined the rules. The agent does the work. Value settles on-chain.
To elevate XAU₮Anchor from a trading script to institutional-grade economic infrastructure, XAU₮Anchor four critical trust layers:
- AI-to-AI Governance (Multi-Sig): Execution is decoupled from risk. The primary agent cannot execute trades without a cryptographic co-signature from an independent, sovereign Risk Node.
- Zero-Knowledge Intent Proofs: Before any WDK transaction is signed, the agent generates a SHA-256 cryptographic commitment of its LLM reasoning (), establishing a verifiable off-chain prep layer.
- Self-Sustaining Economy: The agent utilizes the x402 protocol to autonomously fund its own oracle data via USDT micropayments.
- Native Scudo Accounting: All internal XAU₮ treasury balances are strictly denominated in Scudo (1 XAU₮ = 1000 Scudo), aligning directly with Tether's micro-treasury unit-of-account standards.

real transaction hashes on Polygon Amoy, verifiable on Polygonscan.
Three supply transactions confirmed at time of submission.
Velora USDT↔XAU₮ Swap — MAINNET-READY, TESTNET-SIMULATED
XAU₮ has no DEX liquidity on any EVM testnet — this is a Velora/ecosystem infrastructure gap, not a code limitation. The production code is wired and runs unmodified:
import SwapVeloraEvm from '@tetherto/wdk-protocol-swap-velora-evm'
wdk.registerProtocol('swap-velora', SwapVeloraEvm)
await wdk.executeProtocol('swap-velora', {
fromToken: '0xc2132D05D31c914a87C6611C10748AEb04B58e8F', // USDT — Polygon mainnet
toToken: '0x45804880De22913dAFE09f4980848ECE6EcbAf78', // XAU₮ — Polygon mainnet
amount: BigInt(Math.floor(amountUSD * 1e6)),
slippageTolerance: 50
})Swaps are simulated with realistic slippage (0.1-0.4%) and gas ($0.08-0.20). Zero code changes required to run on Polygon mainnet when Velora pool exists.
