Burn UI

Burn UX Responsibilities

• check EVE allowance
• prepare approve(...) when needed
• simulate AMM.exit(...)
• block duplicate current-batch queued burns
• expose cancellation when protocol rules allow it

Current Write Shapes

EVE.approve(AMM, burnAmount)
AMM.exit(requestedEth, burnAmount, burnPriceTolerance)
AMM.cancelRedemption(batchId)

requestedEth is the quoted ETH for burnAmount at the current base price, reduced by a 0.1% buffer (BURN_REQUEST_BUFFER_BPS). exit() reverts with AMMTooMuchETHRequested if the requested ETH would need more EVE than burnAmount at execution-time NAV, so an unbuffered quote fails on any NAV drop between quote and inclusion. With the buffer, burnAmount acts as the maximum burn and any EVE not needed stays in the wallet.

Important Detail

The pending-request block is based on direct contract reads into the current batch, not on subgraph-only state.
