Building the base layer for L2s: unlocking real-time BFT finality; crosschain composability; and universal compatibility powering our multichain future ☕️
Espresso is a blockchain, but we didn't build another smart contract platform fighting for apps in a zero-sum game. We built foundational infrastructure for sovereign chains that need fast BFT finality and real-time settlement without giving up control. That's Espresso☕- At @ETHGlobal in NYC this week? Be sure to track down @Varunx10 if you’re looking for a top-notch mentor ⤵️If you’re building something that needs fast and reliable transaction confirmation backed by BFT consensus, come talk to me about @EspressoSys Will be around mentoring for the next few days!
- Crosschain composability has a finality problem. Bridges need reliable confirmation of source chain state before they can act. On Ethereum, that could take 16 minutes. Every seamless-looking crosschain product is working around this problem, not solving it 🧵
GIFReplying to @EspressoSysWe demonstrated this with Presto. Users minted NFTs on @ApeChainHUB using funds on @RariChain, or the reverse, no waiting, no bridging. What would have taken minutes took seconds. Not by cutting corners. It's what fast, secure finality at the base layer makes possible.
00:00With Presto, we used NFTs to prove the mechanism. The same principle applies wherever chains need to trust each other: crosschain payments, collateral mobility, onchain financial products. Fast finality isn't a nice-to-have; it's what makes a multichain system composable. - L2s are not dead. But most general-purpose chains with nothing to differentiate them are. Chains built around a specific app, user base, or financial product have a clear reason to exist. @benafisch discusses the state of the L2 ecosystem in @CoinDesk's Protocol newsletter.
- 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 - 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. 🧵⤵️
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.The 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.
