Blockchain engineering capability, base layer to frontier

Protocol layers

L0, L1, L2, and application-specific chains.

Core protocol engineering

Consensus, runtime/VM, cryptography, upgrades.

Node & network ops

Infrastructure, RPC, monitoring, maintenance.

Enterprise & permissioned

Fabric, Corda, private & consortium networks.

Frontier Technology

AI-integrated chains, DePIN, post-quantum.

Protocol Engineering & Core Development

Rust-based core engineering

Protocol development in Rust, the language behind most modern high-performance runtimes.

Consensus mechanism design

Consensus tuned for the finality, throughput, and fault-tolerance your network requires.

Substrate runtime upgrades

On-chain forkless upgrades & pallet development for Substrate-based chains no hard fork.

Protocol migration & network upgrades

Migrating live networks to new versions or new chains with data integrity preserved.

Commonware framework development

Custom consensus and networking primitives outside established blockchain stacks.

Cryptography & VM engineering

Custom precompiles, execution environments, and cryptographic primitives.

Blockchain infrastructure & network architecture

Layer 0 development

Interoperability layer beneath L1s cross-chain communication and shared security primitives.

Layer 1 development

Base-layer networks covering consensus, state architecture, and network parameters.

Layer 2 development

Rollup and sidechain architecture that scales throughput while inheriting base-layer security.

Appchain development

Purpose-built application-specific chains that remove congestion and fee volatility.

Rollup-as-a-Service

Deploy & manage a dedicated rollup sequencer, data availability, and settlement configured for you.

Chain abstraction

Let users and apps interact across chains through one interface no manual bridging or switching.

Interoperability engineered by design

Cross-chain messaging and bridging built into the architecture from the outset on the standards your ecosystem already trusts.
  • IBC integration for Cosmos-based networks
  • LayerZero, Hyperlane, and Chainlink CCIP messaging
  • Shared-security and restaked interoperability via EigenLayer AVSs
  • Aggregation layers and unified liquidity, AggLayer-style

Run reliable networks at scale

Node infrastructure

Node hosting and management for enterprises running dedicated infrastructure rather than third-party RPC.

Validator & RPC operations

High-availability validators, public/private RPC endpoints, and automated snapshots.

Infrastructure maintenance

Node updates, security patching, and performance monitoring after mainnet launch.

“Antier engineered and deployed a custom consensus upgrade for a live DeFi network improving finality with zero disruption to production.”

From protocol to production

Every engagement runs through the same de-risked lifecycle the reason “we maintain what we ship” is more than a slogan

Architecture review

Consensus, permissioning & governance scoped together.

Specification

Consensus, permissioning & governance scoped together.

Implementation

Core engineering in Rust & framework SDKs.

Audit & verification

Security audits & formal verification.

Testnet

Devnet, benchmarking & load testing.

Mainnet

Coordinated launch & genesis.

Maintenance

Upgrades, patching & SLA-backed ops.

Infrastructure decisions made at the Start are the hardest to undo later.

Schedule a technical review

Institutional-grade assurance built into delivery

Audits, formal verification, benchmarking, and quantum-readiness built into the process.
