AUDD Stablecoin Treasury Layer

Purpose

PrivateDAO treats stablecoin settlement as treasury infrastructure, not as a cosmetic token toggle.

The AUDD layer is designed for teams that need:

• Australian-dollar merchant settlement
• governed treasury management in AUD terms
• invoice collection with reviewer-visible proof
• programmable finance flows tied to governance approval
• business-facing payment rails that stay readable from browser to chain

AUDD fits this layer because the sponsor brief is practical and production-oriented: build something people can use, make AUDD the on-chain Australian-dollar asset, and connect it to real payments, settlement, treasury, or programmable finance flows on Solana.

Product lanes

AUDD merchant settlement

The product can stage an AUDD payment request from the browser, attach memo-coded intent, preserve route context, and keep the resulting signature inside the same reviewer path as the treasury request.

Primary routes:

• https://privatedao.org/services#treasury-payment-request
• https://privatedao.org/services/testnet-billing-rehearsal/
• https://privatedao.org/judge/

AUDD treasury management

Treasury operators can prepare AUD-denominated reserve motions, supplier settlement, or invoice funding requests without splitting governance, route logic, and settlement proof across separate tools.

Primary routes:

• https://privatedao.org/services#jupiter-treasury-route
• https://privatedao.org/govern/
• https://privatedao.org/proof/?judge=1

AUDD programmable finance

The same surface can support policy-bound merchant disbursements, recurring treasury operations, and route-reviewed finance actions while keeping governance and wallet execution linked.

Primary routes:

• https://privatedao.org/services/
• https://privatedao.org/documents/agentic-treasury-micropayment-rail/
• https://privatedao.org/documents/treasury-reviewer-packet/

Why AUDD fits the product

The sponsor ask is direct:

• use AUDD meaningfully on Solana
• solve a real financial problem
• ship a smooth user experience
• stay production-oriented

PrivateDAO already matches that shape with:

• wallet-first treasury requests
• governed payout and settlement routing
• SPL token transfer construction in the browser
• memo-coded payment traces
• reviewer-visible signatures, logs, and packet routes

That makes AUDD a strong fit for the existing architecture because we do not need to redesign the product to support an Australian-dollar rail. We need to configure the official AUDD mint and run the same governed flow through the treasury layer.

Technical shape

The web product now exposes AUDD as a first-class treasury asset when these environment values are configured:

NEXT_PUBLIC_TREASURY_AUDD_MINT=
NEXT_PUBLIC_TREASURY_AUDD_RECEIVE_ADDRESS=
NEXT_PUBLIC_TREASURY_AUDD_DECIMALS=6
NEXT_PUBLIC_TREASURY_AUDD_TOKEN_PROGRAM=TokenkegQfeZyiNwAJbNbGKPFXCWuBvf9Ss623VQ5DA
PRIVATE_DAO_MICROPAYMENT_MINT=
PRIVATE_DAO_MICROPAYMENT_SYMBOL=AUDD

The browser flow constructs a wallet-signed SPL token transfer using:

• associated token account derivation
• idempotent destination ATA creation
• TransferChecked
• memo-coded billing and settlement labels
• explorer-visible Testnet signatures

No unverified AUDD mint is hardcoded into the repository. The official Solana mint is injected through environment configuration, and the same route activates the AUDD-specific transfer path with a funded wallet.

Practical grant fit

This layer aligns directly with the grant categories:

• payments: merchant and invoice settlement
• on-chain settlement: wallet-signed AUDD transfers with chain proof
• treasury management: governed reserve and supplier motions
• programmable finance: policy-bound payout and route logic
• merchant tools: request intake and billing rehearsal from the browser

The result is not a slide-deck concept. It is a shipped treasury surface that can be pointed at AUDD as the settlement asset.

Reviewer path

Recommended review order:

1. Open https://privatedao.org/services/testnet-billing-rehearsal/
2. Connect a Solana Testnet wallet.
3. Select AUDD merchant settlement lane or AUDD treasury management lane.
4. Sign the wallet transaction with the official AUDD mint configured and a funded AUDD wallet connected.
5. Open the explorer link and inspect the memo, transfer, and runtime logs.
6. Continue into /services, /judge, /proof/?judge=1, and the treasury reviewer packet.

Current boundary

PrivateDAO now ships the browser route, treasury configuration, payout profiles, and wallet-signed SPL transfer construction for AUDD.

The remaining activation input is the official AUDD Solana mint plus a funded wallet for live asset-specific settlement. The product lane itself is already present and reusable across merchant settlement, treasury management, and programmable finance flows.
