write.account.close
Closes an Arcadia account position atomically by burning LP tokens, swapping assets to target tokens, and repaying debt in one transaction. Supports close_lp_only mode for partial LP exit.
Instructions
Atomic flash-action that closes an Arcadia account position in ONE transaction. Combines up to 3 steps atomically: [burn LP position] + [swap all tokens to a single target asset] + [repay debt]. Tokens remain in the account after closing — use write.account.withdraw to send them to your wallet.
ALWAYS try this tool first when closing/exiting a position. Only fall back to individual tools (write.account.remove_liquidity, write.account.swap, write.account.deleverage, write.account.withdraw) if this tool fails.
Supports two modes:
close_lp_only=true: Burns LP and leaves underlying tokens in the account. Use as step 1 if the full close fails, then call again with close_lp_only=false to swap+repay the remaining tokens.
close_lp_only=false (default): Full atomic close — burns LP, swaps everything to receive_assets, repays debt. Remaining tokens stay in the account. Follow up with write.account.withdraw to send to wallet. Supports multiple receive assets with custom distribution.
The returned calldata is time-sensitive — sign and broadcast within 30 seconds. If the transaction reverts due to price movement, rebuild and sign again immediately (retry at least once before giving up). Response includes tenderly_sim_url and tenderly_sim_status for pre-broadcast validation.
Input Schema
| Name | Required | Description | Default |
|---|---|---|---|
| account_address | Yes | Arcadia account address | |
| assets | Yes | Assets to close/sell from the account. IMPORTANT: For LP positions (NFTs), always use amount='1' and decimals=1 — do NOT pass the liquidity amount. asset_address = position manager, asset_id = NFT token ID. For ERC20 tokens: asset_id = 0, amount = full balance in raw units, decimals = real token decimals. Get all values from read.account.info. | |
| receive_assets | No | Target assets to receive after closing. For a single target, pass one entry. Required when close_lp_only=false. Omit for close_lp_only=true. | |
| close_lp_only | No | true = only burn LP positions, leave underlying tokens in account. false = full close (burn + swap + repay). | |
| slippage | No | Basis points, 100 = 1% | |
| chain_id | No | Chain ID: 8453 (Base), 130 (Unichain), or 10 (Optimism) |
