Nethermind

Tokenised assets fall into three legal categories. Informational — records a fact about an offchain asset Certificatory — digital receipt against a custodian Dispositive — transfer of the token IS transfer of legal title Most tokenised assets today are certificatory.

@cmta_ch @taurus_hq Second collaboration with CMTA. First focused on security tooling for the CMTAT codebase. This one extends the standard into capital markets infrastructure. github.com/CMTA/CMTAT-FIX

CMTAT-FIX: open-source engine from Nethermind, @cmta_ch, and @Taurus_hq. Commits FIX protocol descriptors onchain for CMTAT tokens. Field-level Merkle proof verification, no FIX parsing. Engine + TypeScript SDK. cmta.ch/news-articles/…

Built the engine and TypeScript SDK for this. FIX descriptors committed onchain via Merkle roots, field-level verification without parsing FIX. v0.2.0, open source. github.com/CMTA/CMTAT-FIX x.com/cmta_ch/status…

@cmta_ch @taurus_hq Modular engine, one instance per token. Callers supply a field path and Merkle proof, contract checks it against the stored root. SDK handles the encoding and proof generation offchain.

Every new tokenized security currently requires weeks of custom integration before it can trade or settle. @Nethermind built CMTAT-FIX - in collaboration with CMTA and @Taurus_hq - to fix this, embedding verifiable FIX descriptors on-chain through an open-source modular engine. Standards that work with existing infrastructure, not against it. 🔗 github.com/CMTA/CMTAT-FIX 🔗 Blog post: cmta.ch/news-articles/…

2024: Can AI find smart contract vulnerabilities? 2025: Can you act on the output without drowning in false positives? 2026: How fast, what does it cost, what does it cover? Detection isn't the bottleneck anymore.

eth_getLogs is faster in 1.37.1. The log index work, for indexers and heavy RPC workloads: nethermind.io/blog/speeding-…

The architecture behind Flat DB and why flat storage beats walking the trie for reads: nethermind.io/blog/flat-db-a…

Nethermind Client 1.37.1 is live. Worldstate backend refactor lands with pluggable backends. Flat DB ships opt-in. RocksDB and column DB snapshots. EIP-7928 block-level access lists. Initial zkEVM groundwork and witness generation. EVM hot paths, pruning, and networking hardening throughout. Breaking: Engine API versioning reworked. eth/66 and eth/67 dropped. eth/69 default, eth/70 live.

@Divyansh_S28 Thanks for the PRs. Shipping and learning at the same time is the whole point of the codebase being open.

Been merging a lot of PRs to @Nethermind lately, It's fun contributing and learning at the same time. Thanks to the OG folks.

@dexcompiler Thanks, full credit to the team! 🫶

Congratulations [again] @Nethermind Extreme C# performance engineering on display 👏 docs.stereumlabs.com/blog/ec-sync-s…

On stronger hardware and networking we've seen this drop to around 20 minutes. Full methodology: docs.stereumlabs.com/blog/ec-sync-s…

Nethermind reaches the chain tip in ~90 minutes, using only the Ethereum P2P network. No third-party snapshots, no trusted imports. The fastest way to bring a node online without loosening the trust model. Independently measured by StereumLabs.

@FibrousFinance Appreciate it. Any protocol can plug in the same way, more coming.

Another step for the Agentic DeFi future! Fibrous is part of @Nethermind's defi-skills. Built to reduce friction for humans & agents, we remain a core pillar of the ecosystem. Simply: Best Agentic Swaps. 🐍 defi-skills.nethermind.io

DeFi usually means five tabs open. Swap on one protocol, bridge on another, hunt token addresses, copy them over, approve, sign, hope the slippage holds. defi-skills collapses that into a prompt. Now a plugin for Claude Code and Openclaw, with multi-chain support.

@areta_io @ethereumfndn @chainlinklabs We build Ethereum's execution client and we audit what gets deployed on it. Formal verification, AI-augmented detection, comprehensive review. All accessible through the program. Apply: ethereum.areta.market nethermind.io/nethermind-sec…

Nethermind serves on the Expert Committee for the Ethereum Security Subsidy Program alongside @areta_io, @ethereumfndn, and @chainlinklabs. $1M to subsidize security reviews for Ethereum mainnet builders. Applications are open.

@KaiaChain Most of the work that keeps Ethereum reliable looks like this.

@Nethermind This is the kind of optimization that never makes headlines but quietly determines whether your wallet feels fast or broken. The infra wins that matter most are always the boring ones.

Wallet providers reconstruct transaction history by scanning the chain for events tied to user addresses. The longer the chain gets, the slower that query becomes. This is eth_getLogs without Log Index vs with it, querying a typical user address across increasing block ranges. Nethermind Client, one flag to enable.
