monad-wallet-ops

name	monad-wallet-ops
description	Operates BuddyEvents Monad testnet wallets and on-chain event lifecycle via CLI and Foundry cast. Use when the user asks to create, fund, inspect, or send from agent wallets, OR to create events on-chain, buy tickets, or list tickets for resale.

Monad Wallet & Event Ops (BuddyEvents CLI)

Context

This skill manages agent wallets and the on-chain event lifecycle for this repo using cli/buddyevents and Foundry's cast on Monad testnet (chainId 10143).

Primary capabilities:

• Wallet: wallet setup, wallet fund, wallet balance, wallet send
• Events: events create (API), on-chain createEvent (cast), events list, events cancel
• Tickets: tickets buy (on-chain or x402), tickets sell, tickets list

Key config file: ~/.buddyevents/config.json
Key fields: private_key, wallet_address, contract_address, usdc_address, monad_rpc, api_url

Workflow

Copy this checklist and execute in order:

Full Event Lifecycle Checklist
- [ ] Build CLI
- [ ] Create wallet (or confirm existing)
- [ ] Fund MON from faucet
- [ ] Fund USDC from Circle faucet
- [ ] Check MON + USDC balances
- [ ] Create event (API and/or on-chain)
- [ ] Buy ticket (on-chain or x402)
- [ ] Verify ticket ownership

Part A — Wallet Commands

Run from cli/ after building.

1) Build CLI

cd cli
go build -o buddyevents .

2) Create wallet

./buddyevents wallet setup

Behavior:

• Generates ECDSA private key
• Stores wallet in ~/.buddyevents/config.json
• Prints wallet address and private key

3) Fund testnet MON

./buddyevents wallet fund

Notes:

• Uses Monad agent faucet API with chainId: 10143
• For USDC, use Circle faucet manually: https://faucet.circle.com (select Monad Testnet)

4) Check balances

./buddyevents wallet balance

Outputs:

• MON (native)
• USDC (ERC-20 at configured usdc_address)

5) Send funds

Send MON:

./buddyevents wallet send --token mon --to 0xRECIPIENT --amount 0.01

Send USDC:

./buddyevents wallet send --token usdc --to 0xRECIPIENT --amount 1.5

Part B — Event Creation

B1) Create event via API (Convex backend)

./buddyevents events create \
  --name "Francesco's Participation" \
  --description "Exclusive event" \
  --start 1765000000000 \
  --end 1765007200000 \
  --price 0.01 \
  --max-tickets 50 \
  --team-id REPLACE_TEAM_ID \
  --location "SF"

Required flags: --name, --start, --end, --team-id
Optional: --description, --price (default 0), --max-tickets (default 100), --location, --creator (defaults to config wallet)

Output: Event created: <eventId>

B2) Create event on-chain via cast

Uses the BuddyEvents.createEvent(string name, uint256 priceInUSDC, uint256 maxTickets) contract function.

PRIVATE_KEY=$(jq -r '.private_key' ~/.buddyevents/config.json)
CONTRACT=$(jq -r '.contract_address' ~/.buddyevents/config.json)
RPC=https://testnet-rpc.monad.xyz

cast send --rpc-url "$RPC" \
  --private-key "$PRIVATE_KEY" \
  "$CONTRACT" \
  "createEvent(string,uint256,uint256)" \
  "Francesco's Participation" \
  10000000 \
  50

Parameters:

• name — event name string
• priceInUSDC — price in USDC smallest units (6 decimals: 10000000 = 10 USDC, 0 = free)
• maxTickets — max ticket supply

Output: transaction hash. Parse EventCreated log to get the eventId:

cast receipt --rpc-url "$RPC" <TX_HASH> --json | \
  jq '.logs[0].topics[1]' | xargs cast --to-dec

B3) Verify on-chain event was created

cast call --rpc-url "$RPC" \
  "$CONTRACT" \
  "getEvent(uint256)(string,uint256,uint256,uint256,address,bool)" \
  <EVENT_ID>

Output: (name, priceInUSDC, maxTickets, ticketsSold, organizer, active)

B4) List events via API

./buddyevents events list --status active

---

Part C — Ticket Purchase

C1) Buy ticket on-chain (direct contract call)

./buddyevents tickets buy --on-chain-id <EVENT_ID>

This runs:

1. cast call getEvent() to read price
2. cast send approve() USDC to contract
3. cast send buyTicket() on the contract

C2) Buy ticket via x402 API flow

./buddyevents tickets buy --event-id <CONVEX_EVENT_ID>

This performs the 402 → pay → retry flow automatically.

C3) List ticket for resale

./buddyevents tickets sell --token-id <TOKEN_ID> --price <PRICE_USDC_UNITS>

C4) List owned tickets

./buddyevents tickets list
./buddyevents tickets list --event-id <EVENT_ID>

---

Troubleshooting

• no wallet configured
  Run ./buddyevents wallet setup.

• faucet error (429) or similar
  Faucet rate-limited. Retry later or use https://faucet.monad.xyz.

• RPC error on balance/send
  Check MonadRPC in ~/.buddyevents/config.json (expected https://testnet-rpc.monad.xyz).

• invalid --to address
  Use a checksummed or valid 0x... EVM address.

• Empty name / Zero tickets on createEvent
  Contract requires non-empty name and maxTickets > 0.

• Not organizer on editEvent / cancelEvent
  Only the address that created the event on-chain can modify it.

• USDC transfer failed on buyTicket
  Ensure wallet has sufficient USDC balance and has approved the contract.

Safety

• Never paste private keys in chat or logs.
• wallet setup overwrites current configured wallet in ~/.buddyevents/config.json.
• Confirm recipient address and amount before wallet send.
• On-chain events are immutable once tickets are sold (price cannot change).
• Always verify contract_address in config matches the deployed contract before sending transactions.
