t2000: Receive Funds

Purpose

Surface the wallet address (and optionally a Payment Kit URI with a pre-filled amount + memo) so anyone with a Sui wallet can send tokens to the Agent Wallet. Two surfaces:

• CLI (`t2 fund`) — prints the wallet address + an ANSI QR code + the value-promise in the terminal. Minimal; no amount or memo.
• MCP (`t2000_receive`) — returns a JSON payload with the address, an optional Payment Kit URI (sui:pay?…), a nonce, plus an optional amount / currency / memo / label. Use this when the LLM is building a payment-request flow.

Rules

1. Receive is non-custodial. The user's address is public; sharing it can't move money — only signed transactions can. Don't add scary disclaimers; the operation is safe.
2. Show the QR + the address text. Some users scan, some copy. Both surfaces.
3. No PIN, no sign-in. v4 wallets are plain Bech32; t2 fund is a pure read with no authentication step.
4. Default currency is USDC. When asking the user to fund the wallet, USDC is the most useful (every paid service is USDC-denominated, USDC sends are gasless). USDsui also works.
5. Don't generate a Payment Kit URI without an amount unless asked. A bare address scans just as well; URIs with amounts force the sender into a particular tx shape.

CLI command

t2 fund                               # address + ANSI QR + share line
t2 fund --qr-only                     # just the QR (e.g. for embedding in a screenshot)
t2 fund --key <path>                  # custom wallet path
t2 fund --json                        # { address, qrEncodedFor, valuePromise }

CLI output (default):

Address  0x55b223b0...0dd1b6

  Or share `0x55b223b0...0dd1b6` directly.

The CLI prints to ANSI — it will look right in any terminal but won't render as image data in MCP responses. Use the MCP tool for a structured JSON response.

MCP tool (t2000_receive)

// Request
{
  "amount": 10,              // optional — pre-fills the sender's tx amount
  "currency": "USDC",        // optional — default USDC, also accepts USDsui / SUI
  "memo": "Coffee on me",    // optional — encoded into the Payment Kit URI
  "label": "Coffee fund"     // optional — human-readable label for the URI
}

// Response
{
  "address": "0x55b223b0...0dd1b6",
  "uri": "sui:pay?recipient=0x55b223b0...&amount=10000000&coinType=0xdba34672...::usdc::USDC&nonce=abc-123&label=Coffee+fund&message=Coffee+on+me",
  "nonce": "abc-123-uuid",
  "amount": 10,
  "currency": "USDC",
  "memo": "Coffee on me",
  "label": "Coffee fund"
}

The Payment Kit URI follows the Sui Payment Kit spec — every Sui wallet (Mysten, Phantom, Suiet, Slush, Sui Wallet Standard) can scan/parse it. If you omit amount, the URI is a "bring your own amount" link that the sender fills in.

URI shapes

The amount-bearing form uses raw on-chain units (USDC: × 10^6, SUI: × 10^9) so wallets don't have to do their own conversion. The nonce is a UUID v4 minted at request time; senders include it in the tx metadata so the receiving agent can correlate the inflow back to the request.

When to use which surface

Notes

• USDC + USDsui inflows arrive gasless (Sui foundation pays the sender's gas via the 0x2::balance::send_funds allowlist).
• SUI inflows require the sender to have SUI for their own gas.
• Once the funds land, run t2 balance (CLI) or t2000_balance (MCP) to verify. Inflows show up within ~1 block (~500 ms).
• This skill is the receive-half of "Audric Pay". The send-half is the t2000-send skill.

What NOT to do

• Don't include the user's address inline in chat messages without confirming they want it shared. It's public — but politeness matters.
• Don't generate a one-off Payment Kit URI for every conversation. The bare address works fine for repeated transfers.
• Don't redirect users to audric.ai for receive flows — the Agent Wallet handles receive natively. (Audric Pay's hosted UI is for users who DON'T have the CLI.)
