private/burn_vault_shares
Curator-only endpoint that settles a pending withdraw request by signing a burn approval at a quoted share price (USD per share). Takes the request id and the user’s withdraw-action hash, burns the shares, and returns the settlement result. Requires the curator mint-and-burn permission.

The wallet the request acts for.
The current time in milliseconds, as a decimal string.
EIP-191 signature of the timestamp, by the wallet or one of its session keys.
Body
Fields common to every signed vault action. They appear alongside each endpoint's action-specific parameters in the same request object.
Composite vault request id: (vault_subaccount_id, wallet, vault_nonce)
Useful as a stable dedup key across off-chain and on-chain vault events.

Quoted share price in USD per share, as a decimal string (e.g. "1").
0x-prefixed hex of the 65-byte EOA signature.
x >= 020-byte Ethereum address as a 0x-prefixed lowercase hex string.
42^0x[0-9a-fA-F]{40}$The subaccount the action is signed on; which subaccount applies depends on the specific method — see that method's reference.
x >= 00x-prefixed hex of the 32-byte user withdraw-action hash.
