Espresso ☕️
@EspressoSys
Building the base layer for L2s: unlocking real-time BFT finality; crosschain composability; and universal compatibility powering our multichain future ☕️
When @ApeChainHUB integrated with Espresso, it kept everything. Its sequencer, its 250ms preconfs, its architecture The one change: Espresso finalizes its batches first Unlocking: - BFT finality in seconds - Sequencer equivocation protection - Real-time crosschain composability
- Why are banks and asset managers tokenizing financial products? Distribution, says @benafisch. Going onchain meets users where they already are. Stablecoin holders can put idle capital to work in structured financial products without off-ramping to fiat.

RARI Chain is shutting down. Our genesis NFT collection, The Composables, lives there. Here’s our plan for ensuring The Composables live on. Before @RariChain closes, we’ll take a snapshot of all holder wallets. We’ll then remint the collection on a new chain and airdrop
GIF - Replying to @EspressoSysThe Litecoin incident showed how dangerous it is for crosschain systems to act on source-chain activity that can still reorg. LitVM's Espresso integration addresses that directly. Bridge safety rests on Espresso-finalized state, not probabilistic finality or a single sequencer.
- Replying to @EspressoSysNote: While Espresso finalizes all LitVM-originating transactions, deposits coming from Litecoin, Ethereum, or any other source chain still inherit that chain's finality model. The fix is a conservative wait on inbound deposits. Everything else on LitVM moves at Espresso speed.
- Replying to @EspressoSysThere's another single point of failure Espresso closes: centralized sequencers If a bridge acts on a sequencer's confirmation, a compromised sequencer can revert that transaction and drain the bridge. Espresso-finalized state can't be reverted, even by a compromised sequencer.
- Replying to @EspressoSysFor context on what changed: - Probabilistic finality (Bitcoin, Litecoin): odds of reversal drop with each block. This is why CEXs wait at least 6 blocks before accepting deposits from these chains. - Deterministic finality (Espresso, Ethereum): once final, can't reorg. (Note:
- Replying to @EspressoSysBy using Espresso, LitVM separates two concepts that usually get bundled: finality & settlement Litecoin and Ethereum are still settlement venues for their native assets that users bridge back to them from LitVM. But it's Espresso that finalizes everything that happens on LitVM.
- Replying to @EspressoSysBridges have accepted this risk because stronger finality was too slow. But that tradeoff is now unnecessary. Espresso provides deterministic finality in seconds. Once a transaction is final, it can't reorg. @LitecoinVM chose to integrate with Espresso for exactly this reason.
- Replying to @EspressoSysBridges are extremely sensitive to reorgs. If a bridge pays out on the destination chain before the source-chain transaction is truly final, an attacker can collect on the destination while the original deposit disappears from history. Classic double spend.
- The April Litecoin reorg cost crosschain protocols real money. NEAR Intents lost 11,000 LTC and 7.78 BTC. THORChain was hit for a smaller amount the same day. The root problem wasn't a Litecoin bug. It was probabilistic finality. 🧵⤵️
