Block posting · Arc

Name the block. Name the worst price.

A SELL block escrows the base amount and names the lowest price you accept. A BUY block escrows USDC at the limit plus the fee and names the highest. Makers quote sealed; the best revealed price fills the whole block.

A SELL block escrows the full amount of the base token. It returns if the block cancels.

Posting needs one approval of the escrow token and one transaction. Cancel is free until a maker commits.

What the desk holds

A SELL block: the base amount. A BUY block: USDC for the amount at the limit plus the fee on it. Anything unspent returns at settlement. The owner cannot move it.

When it comes back

Cancel while the seal is open and nobody committed. Or at settlement: no valid quote means the block is cancelled and the escrow plus any forfeited bonds return to you.

Who can settle

Anyone, after the reveal window closes or as soon as every committed maker has revealed. You never depend on a counterparty to act.
