📄️ Block Transitions
Monomer applications must support both the usual Cosmos SDK application functionality and rollup-specific workflows.
📄️ x/rollup
The x/rollup module implements rollup-chain specific logic.
📄️ Deposits
Monomer supports ETH deposits through the OptimismPortal L1 contract. This is the canonical way to move assets from Ethereum to the Monomer rollup chain, and the easiest way to bootstrap liquidity on the rollup chain.
📄️ Withdrawals
Monomer supports ETH withdrawals through the Optimism Portal L1 contract. This is the canonical way to move assets from an OP Stack rollup chain to Ethereum.
📄️ L2 Transactions
Monomer exposes the standard Cosmos BroadcastTX API endpoint for submitting cometbft transactions directly to the rollup chain.
